Russian Govt. Continues Carding Shop Crackdown

Read Time:5 Minute, 9 Second

Russian authorities have arrested six men accused of operating some of the most active online bazaars for selling stolen payment card data. The crackdown — the second closure of major card fraud shops by Russian authorities in as many weeks — comes closely behind Russia’s arrest of 14 alleged affiliates of the REvil ransomware gang, and has many in the cybercrime underground asking who might be next.

Dept. K’s message for Trump’s Dumps users.

On Feb. 7 and 8, the domains for the carding shops Trump’s Dumps, Ferum Shop, Sky-Fraud and UAS were seized by Department K, a division of the Ministry of Internal Affairs of the Russian Federation that focuses on computer crimes. The websites for the carding stores were retrofitted with a message from Dept. K asking, “Which one of you is next?”

According to cyber intelligence analysts at Flashpoint, that same message was included in the website for UniCC, another major and venerated carding shop that was seized by Dept. K in January.

Around the same time Trump’s Dumps and the other three shops began displaying the Dept. K message, the Russian state-owned news outlet TASS moved a story naming six Russian men who were being charged with “the illegal circulation of means of payment.”

TASS reports the six detained include Denis Pachevsky, general director of Saratovfilm Film Company LLC; Alexander Kovalev, an individual entrepreneur; Artem Bystrykh, an employee of Transtekhkom LLC; Artem Zaitsev; an employee of Get-net LLC; and two unemployed workers, Vladislav Gilev and Yaroslav Solovyov.

None of the stories about the arrests tie the men to the four carding sites. But Flashpoint found that all of the domains seized by Dept. K. were registered and hosted through Zaitsev’s company — Get-net LLC.

“All four sites frequently advertised one another, which is generally atypical for two card marketplaces competing in the same space,” Flashpoint analysts wrote.

Stas Alforov is director of research for Gemini Advisory, a New York firm that monitors underground cybercrime markets. Alforov said it is most unusual for the Russians to go after carding sites that aren’t selling data stolen from Russian citizens.

“It’s not in their business to be taking down Russian card shops,” Alforov said. “Unless those shops were somehow selling data on Russian cardholders, which they weren’t.”

A carding shop that sold stolen credit cards and invoked 45’s likeness and name was among those taken down this week by Russian authorities.

Debuting in 2011, Ferum Shop is one of the oldest observed dark web marketplaces selling “card not present” data (customer payment records stolen from hacked online merchants), according to Gemini.

“Every year for the last 5 years, the marketplace has been a top 5 source of card not present records in terms of records posted for sale,” Gemini found. “In this time period, roughly 66% of Ferum Shop’s records have been from United States financial institutions. The remaining 34% have come from over 200 countries.”

In contrast, Trump’s Dumps focuses on selling card data stolen from hacked point-of-sale devices, and it benefited greatly from the January 2021 retirement of Joker’s Stash, which for years dwarfed most other carding shops by volume. Gemini found Trump’s Dumps gained roughly 40 percent market share after Joker’s closure, and that more than 87 percent of the payment card records it sells are from U.S. financial institutions.

“In the past 5 years, Ferum Shop and Trump’s Dumps have cumulatively added over 64 million compromised payment cards,” Alforov wrote. “Based on average demand for CP and CNP records and the median price of $10, the total revenue from these sales is estimated to be over $430 million. Due to the 20 to 30% commission that shops generally receive, the administrators of Ferum Shop and Trump’s Dumps likely generated between $86 and $129 million in profits from these card sales.”

The arrests of the six men comes less than two weeks after Russian law enforcement officials detained four suspected carders — including Andrey Sergeevich Novak, the reputed owner of the extremely popular and long-running UniCC carding shop.

In 2018, the U.S. Justice Department charged Novak and three dozen other defendants thought to be key members of “Infraud,” a long-running cybercrime forum that prosecutors say cost merchants and consumers more than half a billion dollars.

Unicc shop, which sold stolen credit card data as well as Social Security numbers and other consumer information that can be used for identity theft. It was seized by Dept. K in January 2020.

Flashpoint said the recent arrests represent the first major actions against Russia-based cybercriminals since March 2020, when the FSB detained more than thirty members of an illicit carding operation, charging twenty-five of them with “illegal circulation of means of payment.”

Dumps, or card data stolen from compromised point-of-sale devices, have been declining in popularity among fraudsters for years as more financial institutions have issued more secure chip-based cards. In contrast, card-not-present data stolen from online stores continues to be in high demand, because it helps facilitate fraud at online retailers. Gemini says the supply of card-not-present data rose by 50 percent in 2021 versus 2020, fed largely by the success of Magecart e-skimmers that target vulnerabilities in e-commerce sites.

Alforov says while the carding shop closures are curiously timed, he doubts the supply of stolen card data is going to somehow shrink as a result. Rather, he said, some of the lower-tier card shops that were previously just resellers working with Trump’s Dumps and others are now suddenly ramping up inventory with their own new suppliers — very likely thanks to the same crooks who were selling cards to the six men arrested this week in Russia.

“What we’re seeing now is a lot of those reseller shops are coming to the market and saying, ‘We don’t have that order data we were getting from Ferum Shop but now have our own vendors,’” Alforov said. “Some of the lesser tier shops are starting to move up the food chain.”

Multiple Vulnerabilities in SAP Products Could Allow for Remote Code Execution

Read Time:32 Second

Multiple vulnerabilities have been discovered in SAP products, the most severe of which (CVE-2022-22536) could allow for remote code execution. SAP is a software company which creates software to manage business operations and customer relations. Successful exploitation of the most severe of these vulnerabilities could allow an unauthenticated, remote attacker to execute code on the affected systems. Depending on the privileges associated with the application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Applications configured to have fewer restrictions on the system could be less impacted than those who operate with elevated privileges.

CVE-2022-22536: SAP Patches Internet Communication Manager Advanced Desync (ICMAD) Vulnerabilities

Read Time:3 Minute, 30 Second

SAP and Onapsis Research Labs collaborate to disclose three critical vulnerabilities impacting SAP NetWeaver Application Servers. The most severe of the three could lead to full system takeover.

Background

On February 8, SAP disclosed several vulnerabilities in the Internet Communication Manager (ICM), a critical component of its NetWeaver Application Servers in coordination with security researchers at Onapsis who discovered the flaws. SAP and Onapsis have both released write-ups regarding their partnership to discover and patch these flaws. The Cybersecurity and Infrastructure Security Agency also issued an immediate warning about these vulnerabilities, stating that exploitation could result in disrupted operations, data theft, fraud and ransomware attacks.

SAP Netweaver is an application and integration server that acts as the software stack for most of SAP’s applications, including solutions for critical business functions such as enterprise resource planning, customer relationship management and supply chain management.

Analysis

Onapsis Research Labs discovered three critical vulnerabilities in the ICM component of SAP applications. According to the Onapsis Threat Report, the vulnerable ICM component is “present in most SAP products and is a critical part of the overall SAP technology stack,” making these vulnerabilities a major concern for enterprises that deploy SAP products. Because this component connects SAP applications to the internet, it is exposed by default in most deployments.

CVE-2022-22536 is a memory pipes (MPI) desynchronization vulnerability that received the highest CVSSv3 score of 10.0. Onapsis has named this flaw ICMAD for Internet Communication Manager Advanced Desync. An unauthenticated remote attacker could exploit the vulnerability using a simple HTTP request and achieve full system takeover. In addition to being the most critical, CVE-2022-22536 also has the widest effect of all three vulnerabilities, impacting SAP NetWeaver Java or ABAP applications with default configurations.

CVE-2022-22532 is a HTTP request smuggling vulnerability according to SAP in the ICM component. However, Onapsis lists it as a use after free vulnerability. This vulnerability only exists in SAP NetWeaver Java systems. It received a CVSSv3 score of 8.1 and does not require authentication or user interaction to exploit. According to the Onapsis report, certain “more complex [exploit] scenarios” could lead to remote code execution.

CVE-2022-22533 is a memory leak in memory pipe management that could lead to denial of service. It also only affects SAP Application Server Java systems and received a CVSSv3 score of 7.5. An attacker could exploit this flaw using specially crafted HTTP(S) requests to consume all MPI resources.

Proof of concept

Onapsis Research Labs published a scanner script on GitHub for organizations to detect if their SAP instances are vulnerable to CVE-2022-22536. The readme file for the scanner does caution that this script is a best effort attempt at identifying vulnerable instances and cannot provide 100% accuracy.

Solution

As part of its monthly Security Patch Day, SAP published HotNews Security Notes 3123396 and 3123427 (login required) to address CVE-2022-22536 and CVE-2022-22532. The table below lists the SAP products patched. CVE-2022-22533 is not currently listed on the February 2022 Patch Day page.

How to Secure Your Digital Wallet

Read Time:4 Minute, 0 Second

The convenience of tapping your phone at the cash register instead of fumbling for loose change in your physical wallet is undeniable. Nearly 40% of Canadians used their mobile wallets more often in 2020 because of the perceived safety of contactless payment, according to one report.1 While digital wallets and tap to pay is becoming more widespread, you may wonder: what exactly is a digital wallet? Are they safe? 

A digital wallet, also known as a mobile wallet, is a smartphone app that stores your payment information and enables tap to pay at most point-of-sale terminals. A digital wallet is perfectly safe, as long as you guard your smartphone just as closely as you would your physical wallet. 

Here’s why you should secure your digital wallet and three tips to help you do so. 

Why You Should Secure Your Digital Wallet 

Think about what you store in your physical wallet: credit cards, debit cards, driver’s license, library cards, gift cards, cash. Now, imagine (or if you’ve been unlucky enough to lose your wallet in the past, think back to) the hassle that would ensue if someone stole your wallet or you misplaced it. Not only do you have to cancel your cards, notify your various banks, and wait for replacements, but the niggling worry that a stranger has access to your personally identifiable information (PII) will likely keep you up at night. 

Just like you store your wallet in your front pocket when about town and check your seat before leaving a taxi or a plane, look after your smartphone just as closely. Unlike a physical wallet, whose absence is noticed quickly, a digital wallet may be compromised by a cyber pickpocket without you knowing for a while. For example, the BBC reported that researchers found a potential shortcoming in Apple Pay’s Express Transit mode where cyber pickpockets could remotely access mobile wallets.2 Luckily, the researchers’ experiment is unlikely to occur in the real world, but it’s a reminder to everyone to check their monthly bank statements for suspicious transactions. Cybercriminals get smarter and bolder by the day, so it’s not unlikely that they’ll find and exploit a digital wallet shortcoming in the future. 

Follow these tips to help you use your digital wallet more confidently.  

Tips to Protect Your Digital Wallet

1. Set a unique passcode

Always protect your digital wallet with a passcode! This is the best and easiest way to deter cybercriminals. It’s best if this combination of numbers is different than the passcode to your phone. Also, make sure the numbers are random. Birthdays, anniversaries, house addresses, and the last digits of your phone number are all popular combinations and are crackable codes to a resourceful criminal.  

Better yet, if your mobile wallet app allows you to protect your account with facial recognition or a fingerprint scan, set it up! If your digital wallet proves difficult or impossible to enter, a cybercriminal may leave it for an easier target, keeping your PII safe. 

2. Update software regularly

Another way to secure your digital wallet is to make sure you always download the latest software updates. Developers are constantly finding and patching security holes, so the most up-to-date software is often the most secure. Turn on automatic updates to ensure you never miss a new release. 

3. Download digital wallet apps directly from official websites 

Before you swap your plastic cards for digital payment methods, make sure you research the digital banking app before downloading. Make sure that any app you download is through the official Apple or Android store or the financial institution’s official website. Then, check out how many downloads and reviews the app has to make sure you’re downloading an official app and not an imposter. While most of the apps on official stores are legitimate, it’s always best practice to check for typos, blurry logos, and unprofessional app descriptions to make sure. 

Be More Confident Online 

The digital era is an exciting time to make the most of the conveniences technology affords; however, constant vigilance is key to keeping your finances and PII private. Whether you’re looking for additional peace of mind or have lost your wallet, consider signing up for an identity monitoring service like McAfee identity protection. McAfee will monitor your email addresses and bank accounts and alert you to suspicious activities up to 10 months sooner than similar services. Are you curious about how secure your current online habits are? Check your Security Protection Score today and see what steps you can take to live more confidently online.

Breaking 256-bit Elliptic Curve Encryption with a Quantum Computer

Read Time:40 Second

Researchers have calculated the quantum computer size necessary to break 256-bit elliptic curve public-key cryptography:

Finally, we calculate the number of physical qubits required to break the 256-bit elliptic curve encryption of keys in the Bitcoin network within the small available time frame in which it would actually pose a threat to do so. It would require 317 × 106 physical qubits to break the encryption within one hour using the surface code, a code cycle time of 1 μs, a reaction time of 10 μs, and a physical gate error of 10-3. To instead break the encryption within one day, it would require 13 × 106 physical qubits.

In other words: no time soon. Not even remotely soon. IBM’s largest ever superconducting quantum computer is 127 physical qubits.
