Hackers used one of the oldest tricks in the book to turn a buck. All the expense of several thousand Roku users.

Roku notified users that “certain individual Roku accounts” might have been accessed by someone other than their owners. The method of attack involved … credential stuffing, where stolen passwords from one account are “stuffed” into other accounts. With this form of attack, a reused password in one account can give access to several others.

Roku discovered that was the likely cause here, affecting at least 15,000 users.[i]

“Through our investigation, we determined that unauthorized actors had likely obtained certain usernames and passwords of consumers from third-party sources (e.g., through data breaches of third-party services that are not related to Roku).”

So while Roku itself wasn’t breached, hackers used info from other data breaches to break into these accounts, which were sold online. Reportedly for as little as fifty cents each.

With access to the compromised accounts, thieves tried to purchase subscriptions and hardware using stored payment options.

Roku went on to say that these unauthorized actors didn’t get access to “social security numbers, full payment account numbers, dates of birth, or other similar sensitive personal information requiring notification.”

The company said it continues to monitor accounts for unusual activity and that it’s working with subscribers to refund any unauthorized charges.

It has also reset passwords for potentially affected account holders. The company directed users to visit my.roku.com and use the “Forgot password?” option on the sign-in page.

What can I do if I think I got caught up in the Roku breach?

While an estimated 15,000-plus compromised accounts have been identified, the possibility remains that yet more might be at risk as well. Every Roku subscriber should check their account for unusual activity. From there, we suggest updating your password to a new password that’s both strong and unique.

With that, we recommend that you take the following steps, which can help prevent and halt any harm being done with your personal info.

Keep an eye out for phishing attacks.

With some personal info in hand, bad actors might seek out more. They might follow up a breach with rounds of phishing attacks that direct you to bogus sites designed to steal your personal info — either by tricking you into providing it or by stealing it without your knowledge. So look out for phishing attacks, particularly after breaches.

If you are contacted by a company, make certain the communication is legitimate. Bad actors might pose as them to steal personal info. Don’t click or tap on links sent in emails, texts, or messages. Instead, go straight to the appropriate website or contact them by phone directly.

In this case, head to my.roku.com and use the “Forgot password?” option as the company suggests.

Change your passwords and use a password manager.

Changing passwords now is a must. Strong and unique passwords are best, which means never reusing your passwords across different sites and platforms. Using a password manager helps you keep on top of it all, while also storing your passwords securely. Moreover, changing your passwords regularly might make a stolen password worthless because it’s out of date.

Enable two-factor authentication.

While a strong and unique password is a good first line of defense, enabling two-factor authentication across your accounts helps your cause by providing an added layer of security. It’s increasingly common to see nowadays, where banks and all manner of online services will only allow access to your accounts after you’ve provided a one-time passcode sent to your email or smartphone. If your accounts support two-factor authentication, enable it.

Unfortunately at this time, Roku users don’t have this option available to them (although Roku does offer it for its smart home app).

Consider using identity monitoring, particularly for the dark web.

An identity monitoring service can monitor everything from email addresses to IDs and phone numbers for signs of breaches so you can take action to secure your accounts before they’re used for identity theft.​ Personal info harvested from data breaches can end up on dark web marketplaces where other bad actors buy it for their own attacks. Ours monitors the dark web for your personal info and provides early alerts if your data is found on there, an average of 10 months ahead of similar services.​ We also provide guidance to help you act if your info is found.

In the case of the Roku attack, the account thieves purchased compromised accounts on dark web marketplaces. Identity monitoring can help you spot that kind of activity, which then lets you know it’s time to change your passwords.

Check your credit, consider a security freeze, and get ID theft protection.

Although Roku said it found no evidence that account thieves gained access to further sensitive info, treat your info like it was anyway. Strongly consider taking preventive measures now. Checking your credit and getting identity theft protection can help keep you safe in the wake of a breach. Further, a security freeze can help prevent identity theft if you spot any unusual activity. You can get all three in place with our McAfee+ Advanced or Ultimate plans. Features include:

Credit monitoring keeps an eye on changes to your credit score, report, and accounts with timely notifications and guidance so you can take action to tackle identity theft.
Security freeze protects you proactively by stopping unauthorized access to existing credit card, bank, and utility accounts or from new ones being opened in your name. And it won’t affect your credit score.
ID Theft & Restoration Coverage gives you $2 million in identity theft coverage and identity restoration support if determined you’re a victim of identity theft.​ This way, you can cover losses and repair your credit and identity with a licensed recovery expert.

Consider using comprehensive online protection.

A complete suite of online protection software can offer layers of extra security. In addition to more private and secure time online with a VPN, identity monitoring, and password management, it includes web browser protection that can block malicious and suspicious links that might lead you down the road to malware or a phishing scam — which antivirus protection can’t do alone. Additionally, we offer support from a licensed recovery pro who can help you restore your credit, just in case.

Apple and Microsoft recently released software updates to fix dozens of security holes in their operating systems. Microsoft today patched at least 60 vulnerabilities in its Windows OS. Meanwhile, Apple’s new macOS Sonoma addresses at least 68 security weaknesses, and its latest updates for iOS fixes two zero-day flaws.

Last week, Apple pushed out an urgent software update to its flagship iOS platform, warning that there were at least two zero-day exploits for vulnerabilities being used in the wild (CVE-2024-23225 and CVE-2024-23296). The security updates are available in iOS 17.4, iPadOS 17.4, and iOS 16.7.6.

Apple’s macOS Sonoma 14.4 Security Update addresses dozens of security issues. Jason Kitka, chief information security officer at Automox, said the vulnerabilities patched in this update often stem from memory safety issues, a concern that has led to a broader industry conversation about the adoption of memory-safe programming languages [full disclosure: Automox is an advertiser on this site].

On Feb. 26, 2024, the Biden administration issued a report that calls for greater adoption of memory-safe programming languages. On Mar. 4, 2024, Google published Secure by Design, which lays out the company’s perspective on memory safety risks.

Mercifully, there do not appear to be any zero-day threats hounding Windows users this month (at least not yet). Satnam Narang, senior staff research engineer at Tenable, notes that of the 60 CVEs in this month’s Patch Tuesday release, only six are considered “more likely to be exploited” according to Microsoft.

Those more likely to be exploited bugs are mostly “elevation of privilege vulnerabilities” including CVE-2024-26182 (Windows Kernel), CVE-2024-26170 (Windows Composite Image File System (CimFS), CVE-2024-21437 (Windows Graphics Component), and CVE-2024-21433 (Windows Print Spooler).

Narang highlighted CVE-2024-21390 as a particularly interesting vulnerability in this month’s Patch Tuesday release, which is an elevation of privilege flaw in Microsoft Authenticator, the software giant’s app for multi-factor authentication. Narang said a prerequisite for an attacker to exploit this flaw is to already have a presence on the device either through malware or a malicious application.

“If a victim has closed and re-opened the Microsoft Authenticator app, an attacker could obtain multi-factor authentication codes and modify or delete accounts from the app,” Narang said. “Having access to a target device is bad enough as they can monitor keystrokes, steal data and redirect users to phishing websites, but if the goal is to remain stealth, they could maintain this access and steal multi-factor authentication codes in order to login to sensitive accounts, steal data or hijack the accounts altogether by changing passwords and replacing the multi-factor authentication device, effectively locking the user out of their accounts.”

CVE-2024-21334 earned a CVSS (danger) score of 9.8 (1o is the worst), and it concerns a weakness in Open Management Infrastructure (OMI), a Linux-based cloud infrastructure in Microsoft Azure. Microsoft says attackers could connect to OMI instances over the Internet without authentication, and then send specially crafted data packets to gain remote code execution on the host device.

CVE-2024-21435 is a CVSS 8.8 vulnerability in Windows OLE, which acts as a kind of backbone for a great deal of communication between applications that people use every day on Windows, said Kevin Breen, senior director of threat research at Immersive Labs.

“With this vulnerability, there is an exploit that allows remote code execution, the attacker needs to trick a user into opening a document, this document will exploit the OLE engine to download a malicious DLL to gain code execution on the system,” Breen explained. “The attack complexity has been described as low meaning there is less of a barrier to entry for attackers.”

A full list of the vulnerabilities addressed by Microsoft this month is available at the SANS Internet Storm Center, which breaks down the updates by severity and urgency.

Finally, Adobe today issued security updates that fix dozens of security holes in a wide range of products, including Adobe Experience Manager, Adobe Premiere Pro, ColdFusion 2023 and 2021, Adobe Bridge, Lightroom, and Adobe Animate. Adobe said it is not aware of active exploitation against any of the flaws.

By the way, Adobe recently enrolled all of its Acrobat users into a “new generative AI feature” that scans the contents of your PDFs so that its new “AI Assistant” can  “understand your questions and provide responses based on the content of your PDF file.” Adobe provides instructions on how to disable the AI features and opt out here.
