A group of attackers, likely based in Vietnam, that specializes in targeting employees with potential access to Facebook business and ads management accounts, has re-emerged with changes to its infrastructure, malware, and modus operandi after being initially outed a few months ago.
Dubbed DUCKTAIL by researchers from WithSecure, the group uses spear phishing to target individuals on LinkedIn who have job descriptions that could suggest they have access to manage Facebook business accounts. More recently, the attackers were also observed targeting victims via WhatsApp. The compromised Facebook business accounts are used to run ads on the platform for attackers’ financial gain.
