 This post is for all of you, Russian malware lovers/haters. Analyze it all to your heart's content. Prove or disprove Russian hacking in general or DNC hacking in particular, or find that "400 lb hacker" or  nail another country altogether.  You can also have fun and exercise your malware analysis skills without any political agenda.



The post contains malware samples analyzed in the APT28 reports linked below. I will post APT29 and others later.
