DeceptionAds Campaign Steals Millions User Data

The digital landscape is increasingly treacherous, with cybercriminals employing ever more sophisticated methods to steal personal information. A recent, large-scale attack, dubbed "DeceptionAds," highlights the cunning tactics used to compromise millions of users, underscoring the need for heightened online vigilance.

The DeceptionAds Campaign

The DeceptionAds campaign leveraged legitimate advertising networks, Monetag and BeMob, to distribute the Lumma infostealer malware. Attackers created enticing ads promising streaming services or pirated software, luring victims to click. This sophisticated approach bypassed many security measures.

The Fake CAPTCHA Trick

Upon clicking the malicious ads, users were redirected to fake CAPTCHA pages. These pages, deceptively using legitimate BeMob URLs, contained malicious JavaScript code. This code copied a PowerShell command to the victim's clipboard, instructing them to paste and run it, thus installing the Lumma Stealer.
