A likely Russia-affiliated cyber-espionage group is using an increasingly sophisticated malware downloader to target Ukrainian organizations across the transportation, manufacturing, and energy sectors.
According to ESET, the group, tracked as UAC-0099 , is using the downloader, dubbed MatchBoil, to deliver MatchWok, a C# backdoor that gives the attacker persistent access to compromised systems.
