These special skills included recruiting other coders, purchasing and managing servers used to deploy and operate Windows’ nasty Trickbot, encrypting the malware to avoid detection by security software, spamming and phishing potential victims and then laundering the stolen funds. It also added the ability to steal information from victims’ browsers, such as their online account credentials.

“For example, Dunaev developed browser modifications for several widely used open source browsers, such as FireFox and Chrome, using open source code bases for each browser called FireFox Nightly and Chromium,” court documents state. “These changes made it easier and better for remote access gained by Trickbot by allowing actors to steal passwords, credentials, and other stored information.”

Dunaev also admitted to writing code used to steal secrets from infected computers. Between October 2018 and February 2021 alone, the crew defrauded victims of more than $3.4 million, according to court documents.
