Russia didn’t just ratchet up its aggression toward Ukraine on the high seas last week, it also stepped cyber-attacks against the country and other governments and private entities around the world.
Familiar threat actors Fancy Bear – using a packed Zebrocy variant and Cannon payload – and Cozy Bear – delivering a Cobalt Strike Beacon backdoor payload – increased their activity, Stealthcare said, but so did Gamaredon, another threat actor tied to Russia.
"The cyber-attacks are in keeping with Russia’s effort to extend Soviet-style hegemony worldwide—far beyond regional sea skirmishes with Ukraine," said Jeremy Samide CEO of Stealthcare, whose Zero Day Live Threat Intelligence platform detected the attacks.
"Closer to home, a new backdoor attacker has been targeting Ukrainian government agencies. The backdoor, dubbed Pterodo, is associated with the Gamaredon threat group that relies largely on off-the-shelf software and primarily focuses on Ukrainian military and government targets," said Samide. "Pterodo is a custom backdoor that inserts other malware and collects sensitive information. Along with Gamaredon group, it has been tied to Russia’s Federal Security Service (FSB), alongside the Cozy Bear group."
