Researchers from cybersecurity firm Hold Security confirmed that the researcher was able to access the database XMPP chat server of the Conti group.

The leak was also reported by the popular malware researcher Vitali Kremez through BleepingComputer.

The messages are only related to chat conversations since January 21, 2021, their analysis coulg give analysis precious information about the operations conducted by the group, including unreported victims due to private deals with companies that opted out to pay the ransom avoid the public disclosure of the security breach.

These conversations contain various information about the gang’s activities, including previously unreported victims, private data leak URLs, bitcoin addresses, and discussions about their operations.
