The cybercriminal group behind BlackEnergy, the malware family that has been around since 2007 and has made a comeback in 2014 (see our previous blog posts on Back in BlackEnergy *: 2014 Targeted Attacks in Ukraine and Poland and BlackEnergy PowerPoint Campaigns, as well as ourVirus Bulletin talk on the subject), was also active in the year 2015.
ESET has recently discovered that the BlackEnergy trojan was recently used as a backdoor to deliver a destructive KillDisk component in attacks against Ukrainian news media companies and against the electrical power industry. In this blog, we provide details on the BlackEnergy samples ESET has detected in 2015, as well as the KillDisk components used in the attacks. Furthermore, we examine a previously unknown SSH backdoor that was also used as another channel of accessing the infected systems, in addition to BlackEnergy.
