10 Ways to Protect Your Identity

Read Time:9 Minute, 56 Second

We’re online more than ever, in large part because it allows us to take advantage of online conveniences like bill pay and booking appointments. But these many benefits might also leave us exposed to risks, like identity theft.

Identity theft is characterized by one person using another’s personal or financial data for their benefit. Cybercriminals may take information like a person’s name, birthday, Social Security number, driver’s license number, home address, and bank account information and use it for their benefit. A name and matching financial information, for instance, can be used to apply for credit cards or open new accounts.

The good news is that you can safeguard yourself and your family with some best practices — allowing you to enjoy your best life online and worry less about cybercriminals. Share these 10 tips with your family to help keep your entire household safe.

Password-protect your devices with strong passwords

A good habit to get into is to password-protect your computer, tablet, and mobile devices through unique, strong passwords. These devices are home to some of your most sensitive information, including everything from emails to apps that connect to your bank accounts. So, if these devices fall into the wrong hands, a password makes it harder to access your personal data.

Take some time to come up with your passwords, though. It’s important to create strong passwords that hackers can’t guess. A strong password will include a mix of symbols, numbers, and letters. Steer clear of simple passwords like “123456” (it might seem obvious, but this is one of the most common passwords people use). Also, avoid including information that other people can guess, like your birthdate, home address, or name.

Don’t forget to use different passwords for different accounts. If you use the same password across multiple accounts, and a fraudster gains access to one account, they may access the others. Fortunately, McAfee’s identity protection services include a password manager, which can help secure your account credentials across multiple devices. This tool encrypts passwords, storing them safely and making it easy to keep track of them.

Learn how to identify and avoid phishing scams

Identity thieves are skilled at leveraging new technologies. Phishing is one great example of this. Phishing involves criminals masquerading as trustworthy entities, such as government agencies or banks, and using this trusted position to get sensitive information. Phishing scams started with traditional mail. They’re now also done via phone, text, and email.

As a general rule of thumb, never give out any personal information when contacted by a business, bank, or another entity. Also, make sure your email spam filters detect phishing attempts. Never open emails from people you don’t know, and don’t download email attachments without knowing what they are. Some phishing emails include malware, which can infiltrate your device and access personal data. A McAfee Total Protection plan is an all-in-one protection solution that can help you detect and avoid malware.

Fraudulent websites may also use phishing techniques. A website may look similar to the legitimate website of a mortgage lender, bank, or credit card company but might be a fraudulent platform seeking to get information from consumers. Always verify that any website you visit is the legitimate website of the institution, and consider McAfee antivirus software, which offers a safe browsing solution.

Set up alerts through your bank

When financial identity theft occurs, this can also impact financial institutions like banks and lenders. So, they’re eager to prevent fraud, as well. One way they do this is through fraud alerts. You can set up your online banking to issue fraud alerts — for example, via an email, text message, or phone call — if your bank suspects suspicious activity on your account.

In some cases, a bank will also freeze your account until you verify whether the activity is legitimate. This is a common tactic used to protect against credit card fraud. Geo-control is one example: If you live in the U.S., but a German IP address uses your credit card, your credit card provider will likely issue an alert. You can also set up alerts for certain transaction amounts or types.

Review your credit report regularly

Your credit report is one of the most powerful tools you have at your disposal for catching identity thieves and stopping them in their tracks. You’re entitled to a free credit report every 12 months via AnnualCreditReport.com, an initiative of the Federal Trade Commission (FTC). You can get a free copy of your report from each major credit bureau: Experian, Equifax, and TransUnion.

Review your report thoroughly, checking for inaccuracies. When credit monitoring, check your:

Personal information: Verify that your name, address, phone number, birthdate, Social Security number, and employment details are correct.
Accounts: Confirm that all accounts listed are yours and current. Keep an eye out for unrecognized credit cards, utility accounts, phone accounts, or streaming accounts.
Public records: Check for foreclosures, civil suits, liens, or bankruptcies. If these issues are on your credit report and you don’t recognize them, you might be affected by identity fraud.

 

If you find any discrepancies, contact the appropriate credit reporting company. You should also contact the relevant financial institution and visit IdentityTheft.gov. You can report the suspected identity theft and find resources to help you recover.

Be mindful of what you share on social media

Social media is great for connecting with others online, but it does open the door to some vulnerabilities. Be careful about what you post, and steer clear of sharing personal details like your home address, children’s names, pet’s names, or birthdays, which some people use as passwords. If a social media platform offers two-factor authentication, opt in.

Images are another touchy subject. Never post photos that include private data, like a picture of your passport or vaccine card. Consider what’s in the background of any photos — from your home (with a house number) to mail with your address. Finally, you may want to set your visibility to private on all social media accounts, limiting who can view them. And even if your account is private, you should still follow the above tips.

Shred sensitive documents

Some identity thieves get people’s personal information by dumpster diving. One solution? Invest in a paper shredder. You’ll be able to shred documents into tiny bits that are hard to piece together, making it that much harder for someone else to piece together any personal information they contain.

Here are some documents worth shredding:

Debit card statements, credit card statements, and bank statements that contain personal financial information
Invoices or receipts containing details like financial account numbers
Documents containing your Social Security number, like pay stubs and work contracts
Junk mail with contact information, like your name and address
Old photos and IDs, which people can use to create fake IDs
Shipping labels, like those you might get from online retailers to make returns
Medical records or receipts, which may contain insurance information
Canceled checks

If you’re not sure whether something needs to be shredded, go ahead and destroy it. It only takes seconds, and you’re better off safe than sorry.

Protect all of your devices with antivirus software

Whether you use a computer, tablet, or mobile device for many of your online activities, like paying bills, these devices contain a lot of personal data. So, it’s good to protect them from hackers. ​​Install antivirus software like McAfee’s to protect against viruses and spyware. It would be best if you also had a firewall, which is a network security system that controls the incoming and outgoing network traffic based on set security parameters.

To take your device security a step further, you may also want to invest in a virtual private network (VPN). This helps hide your online activity. It can safeguard against hackers on public networks but is also worth using at home. It hides details like browsing activity, personal data, and IP address from potential snoops. McAfee also offers VPN services.

Keep personal documents in a safe space

While your computer, tablet, or mobile device may hold a great deal of personal data, you likely also have hard copies of sensitive documents worth protecting. Documents like your birth certificate, Social Security card, and passport contain valuable information that identity thieves can use for personal gain, so you want to make sure they’re kept in a safe space.

Don’t simply shove these documents into your desk drawer. It’s best to keep them in a locked, fireproof home safe with a secure code. To keep things organized, put each document in a protective plastic sleeve and put the sleeves in a binder. This can be useful if you have a large family and need to keep track of everyone’s data.

Follow the news to learn about data breaches

Sophisticated hackers don’t just target individuals. They may also try to infiltrate businesses, government agencies, higher education institutions, health care facilities, and any other organization that gathers sensitive consumer information. If an entity is subject to a data breach, they’re legally required to notify any consumers who may have been impacted.

However, it’s still good to inform yourself about potential breaches that may affect you. Larger-scale data security risks are usually reported in the media. We also post about data breaches on the McAfee blog. If an entity you do business with has been affected, change your passwords and the passwords of any related accounts immediately.

Know the warning signs of identity theft

Knowing possible signs of identity theft can help you catch it early so that you can continue to enjoy your time online. Educate yourself and your family about these warning signs, ensuring everybody stays safe. Here are some possible indications identity thieves have targeted you:

You receive phone calls from debt collectors about accounts you aren’t familiar with. Don’t provide personal information over the phone immediately. Check your credit report to get the details about the debts in question.
Your credit score experiences unexplained changes. Get a copy of your credit report from the major credit reporting agencies to find out why.
Your bank accounts or credit cards have unknown charges you (and your family) can’t account for. Contact your financial institution to report the suspected fraud, providing relevant documentation to back up your claims. You can also report fraud to your local government.
You receive a fraud alert from your financial institution. Check any activity deemed potentially fraudulent as soon as possible.
You get mail addressed to another person’s name. This could include medical bills, W-2 forms related to unfamiliar employers, or credit card bills, for example. Follow up with the relevant institution.
You experience problems with your tax return For example, the Internal Revenue Service (IRS) may reject your filing if someone else has already filed in your name (to get your tax refund). Contact the IRS fraud department.

You’re only a step away from better protection

The internet keeps all of us connected, but that’s why identity theft protection is important. With people increasingly connected, doing more, and sharing more online, cybercriminals can pinpoint weaknesses and take advantage. Hackers are ready to leverage your information for personal gain, and identity theft is no exception.

McAfee is here to help. McAfee’s identity protection services provide 24/7 monitoring of your email addresses and bank accounts, providing up to $1 million worth of ID theft coverage. You deserve to enjoy the comfort offered by the internet without stressing about identity theft. Implement the best practices above in your household so that you and your loved ones can stay connected with confidence.

5 Common Types of Identity Theft

Read Time:10 Minute, 55 Second

The internet provides plenty of fun and exciting opportunities for you and your family, from sharing on social media to online shopping. To help you enjoy every minute of it, though, it’s good to be aware of what less savory characters are up to.

And they sure have been busy. In fact, the U.S. Federal Trade Commission (FTC) received 2.1 million fraud reports in 2020. What is identity theft? Well, it’s the fraudulent use of another individual’s name and details for personal gain.

Those affected by identity fraud may see a dip in their finances and credit scores. They may also deal with anxiety around financial security going forward. However, while it’s important to be aware of the threat of identity theft, this shouldn’t be cause for alarm. There are plenty of tools and techniques that can help protect you and your family so you can continue to enjoy everything modern technology has to offer.

The first step in protecting yourself? Educate yourself. Understanding the different types of identity theft can help you safeguard yourself and your loved ones so that you can continue all your favorite online activities. Here we’ll define and explore the different types of identity theft to watch out for.

What is identity theft?

We’ve all probably heard of identity theft, but what is it? Identity theft is when someone uses another person’s financial or personal data, usually for monetary gain. This means a fraudster may take sensitive information like names, birthdates, Social Security numbers, driver’s license details, addresses, and bank account numbers or credit card numbers. They might then use this information to make purchases, open credit cards, and even use health insurance to get medical care.

5 types of identity theft

A little knowledge can go a long way in stopping cybercriminals in their tracks — especially since they’re becoming more sophisticated and coming up with new schemes every day.

Here are five common types of identity theft to help you stay one step ahead of hackers.

Financial identity theft

Financial identity theft is when one person uses another’s personal data for financial benefit. This is the most common form of identity theft (including the credit card example described above). Financial identity theft can take multiple forms, including:

Fraudsters may use your credit card information to buy things. We all love to shop online — even criminals. Unfortunately, this issue has become especially prevalent thanks to online shopping during the COVID-19 pandemic.
Hackers may steal funds from your bank account. Sometimes, the amount might be so small that it seems inconsequential, totaling just a few dollars. However, criminals can rack up millions in damages if they target enough people in this way.
Criminals may open new accounts using your Social Security number and other data. For example, a person may use your data to open a new line of credit. They then run through the credit line, leaving you to foot the bill.

The good news is that it’s easy to protect yourself against financial identity theft by checking your bank accounts, credit card statements, and bills. If you see an unexplained charge, contact your credit card company or bank immediately to report it. Also, check your credit report for changes in your score. An unexplained decrease in your score could mean fraudulent activity. You can do this through AnnualCreditReport.com, where you can get a free credit report every 12 months from each of the three major credit bureaus.

Another idea is to place a one-year fraud alert on your credit reports to keep people from opening new accounts in your name. This encourages creditors and lenders to take extra precautions to verify your identity before granting any loans or credit increases. You can also place a security freeze on your credit report, which blocks others from accessing it to extend credit.

Medical identity theft

This might not seem like a real form of identity theft, but it happens. Medical identity theft is when a criminal poses as another person to obtain health care services. In fact, fraudsters may use your name and insurance information to:

Get prescriptions for drugs.
Access medical services, from checkups to costly surgeries.
Obtain medical devices and supplies, such as wheelchairs or hearing aids.

This can result in you having bills for prescriptions, services, or devices you didn’t need, ask for, or even receive. Your health care and insurance records may even have these things added to them. An inaccurate medical record can make it harder for you to get the care you need in the future and even impact insurance coverage.

Fortunately, you can help minimize the risk of medical identity theft by regularly reviewing your medical claims. Contact your insurer if you see unfamiliar procedures, prescriptions, or services. You’ll also want to let your health care provider know so that they can ensure your medical files are correct. Finally, consider filing a complaint with the U.S. Department of Health and Human Services (HHS).

Criminal identity theft

Criminal identity theft occurs when a person arrested by law enforcement uses someone else’s name instead of providing theirs. They might be able to pass this off by creating a fake ID or using a stolen ID, like your driver’s license, to show to the police. This type of fraud can be difficult to detect until the consequences are evident, like:

You receive a court summons. For example, the courts may issue a summons if a criminal uses your ID for unpaid parking tickets.
A bench warrant is issued for your arrest. Unresolved problems like unpaid parking tickets can also result in a judge issuing a bench warrant. You may then be taken into custody at any time, even during a routine traffic stop.
A background check is issued. Sometimes, police will keep an identity theft victim in their database, noting it as an alias for the real criminal. This can result in a false criminal record showing up on your background check. This can cause problems with potential landlords and employers.

You can help protect yourself against criminal identity theft by safeguarding your ID. If your license or state-issued ID is lost or stolen, report it to the local Department of Motor Vehicles (DMV) and law enforcement. Also, limit the information you share online (and encourage family members to do the same). For example, if your teen got their first driver’s license and wants to share a pic of it on social media, explain why this isn’t a good idea.

Synthetic identity theft

As one of the fastest-growing types of financial crime in the U.S., synthetic identity theft involves creating fake identities using real people’s information. Fraudsters may use data like birthdates, addresses, and Social Security numbers from real people, blending them to create a fake profile. They can then use this persona to apply for loans or credit cards or commit other financial crimes. Kids and older adults tend to be vulnerable to this type of fraud since they rarely use their SSNs.

The most important thing about synthetic identity theft is knowing the signs and acting fast. Keep an eye out for any mail with your address on it but addressed to a different name and phone calls or mail about new credit accounts. You can further protect yourself by regularly checking your credit reports for unexplained changes and placing a security freeze on them.

There are also identity monitoring services available, which scan the internet, including the dark web, for breached Social Security numbers. If you suspect you or a loved one is the victim of synthetic identity theft, contact the relevant financial institutions to alert them.

Child identity theft

We all want to protect our children from bad actors, especially when it comes to identity theft. Child identity theft involves using a minor’s information to commit financial fraud, like opening a new account or line of credit under the child’s name. The thief may even use the child’s identity to get a driver’s license, apply for government benefits, or buy a house. This is often easier than targeting an adult because most kids don’t have credit reports or financial accounts, making them a clean slate.

Unfortunately, child identity theft is often perpetrated within the family by a relative who has access to the child’s data like their birthdate and address. And many children don’t realize they’ve been targeted until they’re older — for example, when they try to take out a student loan. By this point, the issue may have been escalating for years. So, it’s important as a parent to be aware of child identity theft.

The best way to do this is to check whether your child has a credit report with any of the three big credit bureaus (TransUnion, Equifax, and Experian). If so, review the report and report any fraudulent activity. You can also place a freeze on your child’s credit report to help minimize the risk of future fraud.

How do you know if you’re a victim of identity theft?

No one wants to be left in the dark when it comes to identity theft, so knowing the signs can help you spot it and take action quickly. This can help stop fraud in its tracks, minimizing both immediate damage and long-term repercussions. Some warning signs that may indicate identity theft include:

You get a fraud alert from a financial institution. To protect customers against identity thieves’ scams, most banks have security protocols to pinpoint potential data breaches. For example, if you live in the U.S., but a purchase is made using your credit card information in London, your bank may stop the transaction and send you a credit card fraud alert.
There are unexplained changes in your credit score. Your credit score going up can mean someone is trying to extend credit in your name (with the intent to run through it). A dip in your score could indicate anything from a loan application to a bill going to collection. You can get a free copy of your credit report from the three major credit bureaus every 12 months.
There are changes to your financial accounts. Check your bank statements at least once a month, keeping an eye out for unfamiliar transactions or withdrawals. Also, check for an increase in your line of credit or a new credit card account (which someone else may have requested in your name).
A loan or credit card application is denied. If you apply for a new credit card or a loan and are turned down, find out why. If you thought you had good credit, double-check your current credit history. Identity theft can result in your credit score
You get phone calls from debt collectors. If collection agencies start calling you about unfamiliar debts, someone else might be using your information to open financial accounts or take out lines of credit. Don’t divulge any personal information on the phone but do check your credit report to see what debts they’re referring to.
You get unfamiliar mail. If you get mail sent to your address that’s clearly for someone else, that person might be using your address for personal gain. Be wary if you receive medical bills in the mail that you don’t recognize or W-2 forms for companies you’ve never worked for.
You experience tax return If you get a tax transcript you didn’t ask for, or the Internal Revenue Service (IRS) rejects your e-filing, identity theft might be to blame. Some thieves will file fraudulent returns to get the victim’s refund. Contact the IRS fraud alert department.

You can also increase your odds of recognizing identity theft with tools like McAfee’s identity protection services. Our continual monitoring can keep tabs on over 60 types of personal information, which allows us to quickly identify security issues, alerting you to potential breaches so that you can fix them.

NY Man Pleads Guilty in $20 Million SIM Swap Theft

Read Time:6 Minute, 11 Second

A 24-year-old New York man who bragged about helping to steal more than $20 million worth of cryptocurrency from a technology executive has pleaded guilty to conspiracy to commit wire fraud. Nicholas Truglia was part of a group alleged to have stolen more than $100 million from cryptocurrency investors using fraudulent “SIM swaps,” scams in which identity thieves hijack a target’s mobile phone number and use that to wrest control over the victim’s online identities.

Truglia admitted to a New York federal court that he let a friend use his account at crypto-trading platform Binance in 2018 to launder more than $20 million worth of virtual currency stolen from Michael Terpin, a cryptocurrency investor who co-founded the first angel investor group for bitcoin enthusiasts.

Following the theft, Terpin filed a civil lawsuit against Truglia with the Los Angeles Superior court. In May 2019, the jury awarded Terpin a $75.8 million judgment against Truglia. In January 2020, a New York grand jury criminally indicted Truglia (PDF) for his part in the crypto theft from Terpin.

A SIM card is the tiny, removable chip in a mobile device that allows it to connect to the provider’s network. Customers can legitimately request a SIM swap when their mobile device has been damaged or lost, or when they are switching to a different phone that requires a SIM card of another size.

But fraudulent SIM swaps are frequently abused by scam artists who trick mobile providers into tying a target’s service to a new SIM card and mobile phone controlled by the scammers. Unauthorized SIM swaps often are perpetrated by fraudsters who have already stolen or phished a target’s password, as many financial institutions and online services rely on text messages to send users a one-time code for multi-factor authentication.

Compounding the threat, many websites let customers reset their passwords merely by clicking a link sent via SMS to the mobile phone number tied to the account, meaning anyone who controls that phone number can reset the passwords for those accounts.

Reached for comment, Terpin said his assailant got off easy.

“I am outraged that after nearly four years and hundreds of pages of evidence that the best the prosecutors could recommend was a plea bargain for a single, relatively minor count of the unauthorized use of a Binance exchange account, when all the evidence points toward Truglia being one of two masterminds of a wide-ranging criminal conspiracy to steal crypto from me and others,” Terpin told KrebsOnSecurity.

Terpin said public court records already show Truglia bragging about stealing his funds and using it to finance a lavish lifestyle.

“He at the very least withdrew 100 bitcoin (worth $1.6 million at the time and nearly $5 million today) from my theft into his wallet at a separate, US-based exchange, and then moved or spent it,” Terpin said. “The fact is that the intentional theft of $24 million, whether taken at the point of a gun in a bank or through a SIM card swap, is a major felony. Truglia should be prosecuted to the fullest extent of the law.”

Terpin also is waging an ongoing civil lawsuit against 18-year-old Ellis Pinsky, who’s accused of working with Truglia as part of a SIM swapping crew that has stolen more than $100 million in cryptocurrency. According to Terpin, Pinsky was 15 when he took part in the $24 million 2018 SIM swap, but he returned $2 million worth of cryptocurrency after being confronted by Terpin’s investigators.

“On the surface, Pinsky is an ‘All American Boy,’” Terpin’s civil suit charges. “The son of privilege, he is active in extracurricular activities and lives a suburban life with a doting mother who is a prominent doctor.”

“Despite their wholesome appearances, Pinsky and his other cohorts are in fact evil computer geniuses with sociopathic traits who heartlessly ruin their innocent victims’ lives and gleefully boast of their multi-million-dollar heists,” the lawsuit continues. “Pinsky is reputed to have used his ill-gotten gains to purchase multi-million-dollar watches and is known to go on nightclub sprees at high end clubs in New York City, and Truglia rented private jets and played the part of a dashing playboy with young women pampering him.”

Pinksy could not be immediately reached for comment. But a review of the latest filings in the lawsuit show that Pinsky’s attorneys stopped representing him because he no longer had the funds to pay for their services. The most recent entry in the New York Southern District’s docket asks the court to give Pinsky additional time to seek counsel, and hints that barring that he may end up representing himself.

Truglia is still being criminally prosecuted in Santa Clara, Calif., the home of the REACT task force, which pursues SIM-swapping cases nationwide. In November 2018, REACT investigators and New York authorities arrested Truglia on suspicion of using SIM swaps to steal approximately $1 million worth of cryptocurrencies from Robert Ross, a San Francisco father of two who later went on to found the victim advocacy website stopsimcrime.org.

According to published reports, Truglia and his accomplices also perpetrated SIM swaps against the CEO of the blockchain storage service 0Chain; hedge-funder Myles Danielson, vice president of Hall Capital Partners; and Gabrielle Katsnelson, the co-founder of the startup SMBX.

Truglia is currently slated to be sentenced in April 2022 for his guilty plea in New York. He faces a maximum sentence of up to 20 years in prison.

Erin West, deputy district attorney for Santa Clara County, told KrebsOnSecurity that SIM swapping remains a major problem. But she said many of the victims they’re now assisting are relatively new cryptocurrency investors for whom a SIM swapping attack can be financially devastating.

“Originally, the SIM swap targets were the early adopters of crypto,” West said. “Now we’re seeing a lot more of what I would call normal people trying their hand at crypto, and that makes a lot more people a target. It makes people who are unfamiliar with their personal security online vulnerable to hackers whose entire job is to figure out how to part people from their money.”

West said REACT continues to train state and local law enforcement officials across the country on how to successfully investigate and prosecute SIM swapping cases.

“The good news is our partners across the nation are learning how to conduct these cases,” she said. “Where this was a relatively new phenomenon three years ago, other smaller jurisdictions around the country are now learning how to prosecute this crime.”

All of the major wireless carriers let customers add security against SIM swaps and related schemes by setting a PIN that needs to be provided over the phone or in person at a store before account changes should be made. But these security features can be bypassed by incompetent or corrupt mobile store employees.

Microsoft Patch Tuesday, December 2021 Edition

Read Time:5 Minute, 17 Second

Microsoft, Adobe, and Google all issued security updates to their products today. The Microsoft patches include six previously disclosed security flaws, and one that is already being actively exploited. But this month’s Patch Tuesday is overshadowed by the “Log4Shell” 0-day exploit in a popular Java library that web server administrators are now racing to find and patch amid widespread exploitation of the flaw.

Log4Shell is the name picked for a critical flaw disclosed Dec. 9 in the popular logging library for Java called “log4j,” which is included in a huge number of Java applications. Publicly released exploit code allows an attacker to force a server running a vulnerable log4j library to execute commands, such as downloading malicious software or opening a backdoor connection to the server.

According to researchers at Lunasec, many, many services are vulnerable to this exploit.

“Cloud services like Steam, Apple iCloud, and apps like Minecraft have already been found to be vulnerable,” Lunasec wrote. “Anybody using Apache Struts is likely vulnerable. We’ve seen similar vulnerabilities exploited before in breaches like the 2017 Equifax data breach. An extensive list of responses from impacted organizations has been compiled here.”

“If you run a server built on open-source software, there’s a good chance you are impacted by this vulnerability,” said Dustin Childs of Trend Micro’s Zero Day Initiative. “Check with all the vendors in your enterprise to see if they are impacted and what patches are available.”

Part of the difficulty in patching against the Log4Shell attack is identifying all of the vulnerable web applications, said Johannes Ullrich, an incident handler and blogger for the SANS Internet Storm Center. “Log4Shell will continue to haunt us for years to come. Dealing with log4shell will be a marathon,” Ullrich said. “Treat it as such.” SANS has a good walk-through of how simple yet powerful the exploit can be.

John Hultquist, vice president of intelligence analysis at Mandiant, said the company has seen Chinese and Iranian state actors leveraging the log4j vulnerability, and that the Iranian actors are particularly aggressive, having taken part in ransomware operations that may be primarily carried out for disruptive purposes rather than financial gain.

“We anticipate other state actors are doing so as well, or preparing to,” Hultquist said. “We believe these actors will work quickly to create footholds in desirable networks for follow-on activity, which may last for some time. In some cases, they will work from a wish list of targets that existed long before this vulnerability was public knowledge. In other cases, desirable targets may be selected after broad targeting.”

Researcher Kevin Beaumont had a more lighthearted take on Log4Shell via Twitter:

“Basically the perfect ending to cybersecurity in 2021 is a 90s style Java vulnerability in an open source module, written by two volunteers with no funding, used by large cybersecurity vendors, undetected until Minecraft chat got pwned, where nobody knows how to respond properly.”

The Cybersecurity and Infrastructure Security Agency (CISA) has joined with the FBI, National Security Agency (NSA) and partners abroad in publishing an advisory to help organizations mitigate Log4Shell and other Log4j-related vulnerabilities.

A half-dozen of the vulnerabilities addressed by Microsoft today earned its most dire “critical” rating, meaning malware or miscreants could exploit the flaws to gain complete, remote control over a vulnerable Windows system with little or no help from users.

The Windows flaw already seeing active exploitation is CVE-2021-43890, which is a “spoofing” bug in the Windows AppX installer on Windows 10. Microsoft says it is aware of attempts to exploit this flaw using specially crafted packages to implant malware families like Emotet, Trickbot, and BazaLoader.

Kevin Breen, director of threat research for Immersive Labs, said CVE-2021-43905 stands out of this month’s patch batch.

“Not only for its high CVSS score of 9.6, but also because it’s noted as ‘exploitation more likely’,” Breen observed.

Microsoft also patched CVE-2021-43883, an elevation of privilege vulnerability in Windows Installer.

“This appears to be a fix for a patch bypass of CVE-2021-41379, another elevation of privilege vulnerability in Windows Installer that was reportedly fixed in November,” Satnam Narang of Tenable points out. “However, researchers discovered that fix was incomplete, and a proof-of-concept was made public late last month.”

Google issued five security fixes for Chrome, including one rated critical and three others with high severity. If you’re browsing with Chrome, keep a lookout for when you see an “Update” tab appear to the right of the address bar. If it’s been a while since you closed the browser, you might see the Update button turn from green to orange and then red. Green means an update has been available for two days; orange means four days have elapsed, and red means your browser is a week or more behind on important updates. Completely close and restart the browser to install any pending updates.

Also, Adobe issued patches to correct more than 60 security flaws in a slew of products, including Adobe Audition, Lightroom, Media Encoder, Premiere Pro, Prelude, Dimension, After Effects, Photoshop, Connect, Experience Manager and Premiere Rush.

Standard disclaimer: Before you update Windows, please make sure you have backed up your system and/or important files. It’s not uncommon for a Windows update package to hose one’s system or prevent it from booting properly, and some updates have been known to erase or corrupt files.

So do yourself a favor and backup before installing any patches. Windows 10 even has some built-in tools to help you do that, either on a per-file/folder basis or by making a complete and bootable copy of your hard drive all at once.

And if you wish to ensure Windows has been set to pause updating so you can back up your files and/or system before the operating system decides to reboot and install patches on its own schedule, see this guide.

If you experience glitches or problems installing any of these patches this month, please consider leaving a comment about it below; there’s a decent chance other readers have experienced the same and may chime in here with useful tips.

Inside Ireland’s Public Healthcare Ransomware Scare

Read Time:8 Minute, 40 Second

The consulting firm PricewaterhouseCoopers recently published lessons learned from the disruptive and costly ransomware attack in May 2021 on Ireland’s public health system. The unusually candid post-mortem found that nearly two months elapsed between the initial intrusion and the launching of the ransomware. It also found affected hospitals had tens of thousands of outdated Windows 7 systems, and that the health system’s IT administrators failed to respond to multiple warning signs that a massive attack was imminent.

PWC’s timeline of the days leading up to the deployment of Conti ransomware on May 14.

Ireland’s Health Service Executive (HSE), which operates the country’s public health system, got hit with Conti ransomware on May 14, 2021. A timeline in the report (above) says the initial infection of the “patient zero” workstation happened on Mar. 18, 2021, when an employee on a Windows computer opened a booby-trapped Microsoft Excel document in a phishing email that had been sent two days earlier.

Less than a week later, the attacker had established a reliable backdoor connection to the employee’s infected workstation. After infecting the system, “the attacker continued to operate in the environment over an eight week period until the detonation of the Conti ransomware on May 14, 2021,” the report states.

According to PWC’s report (PDF), there were multiple warnings about a serious network intrusion, but those red flags were either misidentified or not acted on quickly enough:

On Mar. 31, 2021, the HSE’s antivirus software detected the execution of two software tools commonly used by ransomware groups — Cobalt Strike and Mimikatz — on the Patient Zero Workstation. But the antivirus software was set to monitor mode, so it did not block the malicious commands.”
On May 7, the attacker compromised the HSE’s servers for the first time, and over the next five days the intruder would compromise six HSE hospitals. On May 10, one of the hospitals detected malicious activity on its Microsoft Windows Domain Controller, a critical “keys to the kingdom” component of any Windows enterprise network that manages user authentication and network access.
On 10 May 2021, security auditors first identified evidence of the attacker compromising systems within Hospital C and Hospital L. Hospital C’s antivirus software detected Cobalt Strike on two systems but failed to quarantine the malicious files.
On May 13, the HSE’s antivirus security provider emailed the HSE’s security operations team, highlighting unhandled threat events dating back to May 7 on at least 16 systems. The HSE Security Operations team requested that the Server team restart servers.

By then it was too late. At just after midnight Ireland time on May 14, the attacker executed the Conti ransomware within the HSE. The attack disrupted services at several Irish hospitals and resulted in the near complete shutdown of the HSE’s national and local networks, forcing the cancellation of many outpatient clinics and healthcare services. The number of appointments in some areas dropped by up to 80 percent.”

Conti initially demanded USD $20 million worth of virtual currency in exchange for a digital key to unlock HSE servers compromised by the group. But perhaps in response to the public outcry over the HSE disruption, Conti reversed course and gave the HSE the decryption keys without requiring payment.

Still, the work to restore infected systems would take months. The HSE ultimately enlisted members of the Irish military to bring in laptops and PCs to help restore computer systems by hand. It wasn’t until September 21, 2021 that the HSE declared 100 percent of its servers were decrypted.

As bad as the HSE ransomware attack was, the PWC report emphasizes that it could have been far worse. For example, it is unclear how much data would have been unrecoverable if a decryption key had not become available as the HSE’s backup infrastructure was only periodically backed up to offline tape.

The attack also could have been worse, the report found:

if there had been intent by the Attacker to target specific devices within the HSE environment (e.g. medical devices);
if the ransomware took actions to destroy data at scale;
if the ransomware had auto-propagation and persistence capabilities, for example by using an exploit to propagate across domains and trust-boundaries to medical devices (e.g. the EternalBlue exploit used by the WannaCry and NotPetya15 attacks);
if cloud systems had also been encrypted such as the COVID-19 vaccination system

The PWC report contains numerous recommendations, most of which center around hiring new personnel to lead the organization’s redoubled security efforts. But it is clear that the HSE has an enormous amount of work ahead to grow in security maturity. For example, the report notes the HSE’s hospital network had over 30,000 Windows 7 workstations that were deemed end of life by the vendor.

“The HSE assessed its cybersecurity maturity rating as low,” PWC wrote. “For example, they do not have a CISO or a Security Operations Center established.”

PWC also estimates that efforts to build up the HSE’s cybersecurity program to the point where it can rapidly detect and respond to intrusions are likely to cost “a multiple of the HSE’s current capital and operation expenditure in these areas over several years.”

One idea of a “security maturity” model.

In June 2021, the HSE’s director general said the recovery costs for the May ransomware attack were likely to exceed USD $600 million.

What’s remarkable about this incident is that the HSE is publicly funded by the Irish government, and so in theory it has the money to spend (or raise) to pay for all these ambitious recommendations for increasing their security maturity.

That stands in stark contrast to the healthcare system here in the United States, where the single biggest impediment to doing security well continues to be lack of making it a real budget priority. Also, most healthcare organizations in the United States are private companies that operate on razor-thin profit margins.

I know this because in 2018 I was asked to give the keynote at an annual gathering of the Healthcare Information Sharing and Analysis Group (H-ISAC), an industry group centered on sharing information about cybersecurity threats. I almost didn’t accept the invitation: I’d written very little about healthcare security, which seemed to be dominated by coverage of whether healthcare organizations complied with the letter of the law in the United States. That compliance centered on the Health Insurance Portability and Accountability Act (HIPAA), which prioritizes protecting the integrity and privacy of patient data.

To get up to speed, I interviewed over a dozen of the healthcare security industry’s best and brightest minds. A common refrain I heard from those interviewed was that if it was security-related but didn’t have to do with compliance, there probably wasn’t much chance it would get any budget.

Those sources unanimously said that however well-intentioned, it’s not clear that the “protect the data” regulatory approach of HIPPA was working from an overall threat perspective. According to HealthcareIT News, more than 40 million patient records have been compromised in incidents reported to the federal government in 2021 so far alone.

During my 2018 talk, I tried to emphasize the primary importance of being able to respond quickly to intrusions. Here’s a snippet of what I told that H-ISAC audience:

“The term ‘Security Maturity’ refers to the street smarts of an individual or organization, and this maturity generally comes from making plenty of mistakes, getting hacked a lot, and hopefully learning from each incident, measuring response times, and improving.

Let me say up front that all organizations get hacked. Even ones that are doing everything right from a security perspective get hacked probably every day if they’re big enough. By hacked I mean someone within the organization falls for a phishing scam, or clicks a malicious link and downloads malware. Because let’s face it, it only takes one screw up for the hackers to get a foothold in the network.

Now this is in itself isn’t bad. Unless you don’t have the capability to detect it and respond quickly. And if you can’t do that, you run the serious risk of having a small incident metastasize into a much larger problem.

Think of it like the medical concept of the ‘Golden Hour:’ That short window of time directly following a traumatic injury like a stroke or heart attack in which life-saving medicine and attention is likely to be most effective. The same concept holds true in cybersecurity, and it’s exactly why so many organizations these days are placing more of their resources into incident response, instead of just prevention.”

The United States’ somewhat decentralized healthcare system means that many ransomware outbreaks tend to be limited to regional or local healthcare facilities. But a well-placed ransomware attack or series of attacks could inflict serious damage on the sector: A December 2020 report from Deloitte says the top 10 health systems now control a 24 percent market share and their revenue grew at twice the rate of the rest of the market.

In October 2020, KrebsOnSecurity broke the story that the FBI and U.S. Department of Homeland Security had obtained chatter from a top ransomware group which warned of an “imminent cybercrime threat to U.S. hospitals and healthcare providers.” Members associated with the Russian-speaking ransomware group known as Ryuk had discussed plans to deploy ransomware at more than 400 healthcare facilities in the United States.

Hours after that piece ran, I heard from a respected H-ISAC security professional who questioned whether it was worth getting the public so riled up. The story had been updated multiple times throughout the day, and there were at least five healthcare organizations hit with ransomware within the span of 24 hours.

“I guess it would help if I understood what the baseline is, like how many healthcare organizations get hit with ransomware on average in one week?” I asked the source.

“It’s more like one a day,” the source confided.

In all likelihood, the HSE will get the money it needs to implement the programs recommended by PWC, however long that takes. I wonder how many U.S.-based healthcare organizations could say the same.
