According to the report, Andrey Gorbachov and Gleb Sluchevsky used online quizzes for installing malicious browser extensions. They kind of overlayed their own advertisements onto Facebook’s news feed, when the users visited their profiles from other browsers. Such method possibly was used in order to work friends’ names into the ad copy, repeating the form of many Facebook ads.
The men from Kyiv worked under nicknames such as Olena Stelma, Amanda Pitt and Ihor Kolomiyets. Their scheme had been working till October 2018.
Facebook claims that this scheme is oriented on the Russian users. The fight against this scheme brought over $75,000 damages to the company.
