Conti Ransomware Gang Has Full Log4Shell Attack Chain
The Conti ransomware gang, which last week became the first professional crimeware outfit to adopt and weaponize the Log4Shell vulnerability, has now built up a holistic attack chain.
The sophisticated Russia-based Conti group – which Palo Alto Networks has called “one of the most ruthless” of dozens of ransomware groups currently known to be active – was in the right place at the right time with the right tools when Log4Shell hit the scene 10 days ago, security firm Advanced Intelligence (AdvIntel) said in a report shared with Threatpost on Thursday.
As of today, Monday, Dec. 20, the attack chain has taken the following form, AdvIntel’s Yelisey Boguslavskiy told Threatpost: Emotet -> Cobalt Strike -> Human Exploitation -> (no ADMIN$ share) -> Kerberoast -> brute -> vCenter ESXi with log4shell scan for vCenter.
