Facebook this week announced filing two lawsuits - one against an organization and its agents and one against four individuals in Vietnam - over advertising-related schemes.
According to Facebook, four individuals residing in Vietnam employed session/cookie theft techniques to compromise the accounts of employees at advertising and marketing agencies, leveraging them to run unauthorized ads.
As part of their scheme, the defendants allegedly used a malicious Android application, called "Ad Manager for Facebook," to take control of the accounts.
The defendants, Thêm Hữu Nguyễn, Lê Khang, Nguyễn Quốc Bảo, and Pham Hữu Dung, created the Ad Manager for Facebook application and also tricked users into installing it.
The app prompted users to provide Facebook login details, along with other information, which the defendants then used to access the victims' Facebook accounts and run ads, including some that promoted online scams.
As part of the scheme, deceptive ads were placed on Facebook to promote merchandise such as clothing, watches, and toys.
