Gafgyt is a botnet that was uncovered in 2014. It is notorious for launching large-scale distributed denial-of-service (DDoS) attacks. Security researchers now discovered the activities of the latest variant, which they call Gafgyt_tor, for the first time on February 15, 2015.

To evade detection, Gafgyt_tor uses the Tor anonymization network to hide its command-and-control (C2) communications and encrypts sensitive strings in messages. The use of Tor by malware families is nothing new, but researchers said they have not seen Gafgyt exploit the anonymity network before. More details can be found in this article.
