“Though the group’s reported variety of profitable assaults appears giant, statistical info signifies the opposite,” explains Martin Chlumecky, malware researcher at Avast. “The group’s success fee is 40%. Web sites hosted on well-secured servers can face up to the assaults. Round 20% of the assaults the group claims to be liable for didn’t match the targets listed of their configuration recordsdata.”
The group controls unprotected PCs around the globe contaminated with malware known as Bobik, which act as bots. Bobik first emerged in 2020 and was used as a distant entry instrument prior to now.

At one time, they will successfully strike about 13 URL addresses without delay, judging by configuration historical past, together with subdomains,” continues Martin Chlumecky. “Moreover, one XML configuration usually features a outlined area as a set of subdomains, so Bobik successfully assaults 5 completely different domains inside one configuration. Consequently, they can’t deal with extra domains for capability and effectivity causes.”
NoName057(16)’s extra profitable assaults affected corporations with easy, informational websites, together with simply an about, mission, and a contact web page, for instance. The servers of web sites like these will not be sometimes designed to be closely loaded and infrequently don’t implement anti-DDoS strategies, making them a simple goal.
