Facebook accounts hit with malicious ad attack with dangerous malware
In an alarming revelation, Bitdefender Labs has uncovered a sinister turn in cybercrime tactics on Facebook. Hackers are using a new virus called NodeStealer to steal your cookies and passwords. It’s a sneaky piece of code that runs on JavaScript and Node.js, and it can grab your web browser data and use it to hack into your Facebook account.
How do they do it? Well, they use cunning malvertising campaigns, which are fake ads that look like they’re from Meta, the company that owns Facebook. When you click on these ads, you’re actually downloading the NodeStealer virus, which then starts to spy on your online activity.

Hackers will post ads on Facebook with pictures of pretty girls, hoping to get you to click on them. But don’t fall for it. These ads are actually hiding a nasty virus that can steal your passwords and personal information.
Bitdefender researchers found that at least 10 Facebook accounts that belong to businesses have been hacked and used to spread these ads. The ads have a link that says, "Photo Album," but when you click on it, you download a file that infects your computer. The file then gets access to your browser cookies and passwords, which lets the hackers get into your accounts.

The sheer reach of these campaigns is deeply concerning. Bitdefender's analysis estimates an astounding 100,000 potential downloads, with a single ad amassing up to 15,000 downloads within a mere 24-hour span. Demographically, males over 45 are the most impacted, highlighting the targeted nature of these attacks.

Originally identified by Meta's security team in early 2023, NodeStealer has undergone a rapid and troubling transformation. The malware, initially devised to steal browser cookies and execute large-scale account takeovers, now boasts enhanced features enabling unauthorized entry into additional platforms like Gmail and Outlook. Its expanded capabilities even extend to stealing crypto wallet balances and downloading further malicious payloads.

The attackers' modus operandi is both clever and calculated. Utilizing ad credit balances from hijacked business accounts, they run ads that distribute the NodeStealer malware to a specifically chosen group of people.
They establish Facebook pages with names like "Album Update" or "Hot Album Update Today," alluring users with the promise of exclusive, risqué content. Yet, the promised "albums" are merely a façade for spreading NodeStealer malware.

To detect and defend against NodeStealer's nasty threat, you should adopt a multi-layered approach:
Implement robust security solutions from good antivirus protection: The cornerstone of digital defense is to have a reliable security solution installed on your device. Having good antivirus software actively running on your devices will alert you of any malware in your system, warn you against clicking on any malicious links in phishing emails, and ultimately protect you from being hacked. Review of the 2023 Best Antivirus Protection here.
Practice good cyber hygiene: Exercise caution in your digital interactions. Refrain from clicking on unsolicited links, particularly those associated with alarming notifications or ads urging you to download enticing media files.
Beware of suspicious ads: Specifically, for this NodeStealer campaign, you should be wary of any ad prompting the download of photo albums, especially if the source is Bitbucket, Gitlab, or Dropbox. Such ads are likely traps set by cybercriminals to deploy NodeStealer malware onto your device.
Scrutinize unusual account activity: Keep an eye out for any unusual activity on your accounts. Unexpected password-reset emails, unrecognized logins, or uninitiated security changes can be red flags signaling a compromised account.
Educate and inform: Share your knowledge about these threats with friends and family. The more informed people are, the less likely they are to fall victim to these schemes. Sign up for my security alerts by subscribing to my CyberGuy Newsletter here.
