Following the invasion of Ukraine, a member of the Conti ransomware group believed to be of Ukrainian origin leaked the gang’s internal communications after the group’s leaders posted an aggressive pro-Russian message on their official website on Friday, in the aftermath of the Russian invasion of the country. Internal records were disclosed via an email that was provided to a number of journalists and security experts, among other people. The records include chat logs going back a year, as well as source code for a variety of malware used by the Conti ransomware gang. This leak is a veritable goldmine of threat intelligence for researchers interested in how a successful ransomware gang of Conti’s size operates.
