VB2017 video: Turning Trickbot: decoding an encrypted command-and-control channel

Posted by Martijn Grooten on Nov 3, 2017

Trickbot, a banking trojan which appeared this year, seems to be a new, more modular, and more extensible malware descendant of the notorious Dyre botnet trojan. At VB2017, Symantec researcher Andrew Brandt presented a walkthrough of a typical Trickbot infection process, and its aftermath, as seen through the lens of a tool used to perform man-in-the-middle decryption. Today, we publish both Andrew's slides and the recording of his presentation.
