PRODAFT’s findings are the results of information compiled between April and December 2023 by intercepting 1000’s of communication logs between varied menace actors affiliated with totally different ransomware variants.
Matveev is alleged to steer a staff of six penetration testers – 777, bobr.kurwa, krbtgt, shokoladniy_zayac, WhyNot, and dushnila – to execute the assaults. The group has a flat hierarchy, fostering higher collaboration between the members.
