The researcher who leaked internal chats from the Conti ransomware group has now published its source code and appears to have doxxed one of its developers.

The leaker, going under the Twitter name @Contileaks, had originally published internal chats from the group on Sunday in response to its declaration of support for the Russian invasion of Ukraine. They followed it up by publishing the source code overnight.

The researcher published the code as a password-protected file, prompting a flurry of requests for access. They explained that they would release the password to trusted parties, saying in a tweet: “conti src password shared only with trusted ppl for now. to avoid more damage!”




However, earlier this week, another researcher appeared to have cracked the password and shared the code online.

Other code released in the ContiLeaks dumps appears to include the source for the TrickBot command dispatcher and data collector. The researcher also published access details for several storage servers used by the Conti group yesterday.

The leak also extended to personal information. The researcher tweeted what they claim is the GitHub page and Gmail address gleaned from the code. The address is flagged in the code as an developer for the Conti group, but responses to the tweet suggest that the developer did not know that he was writing back-end code for a ransomware operation.

Amid the data posts, the researcher continued to criticize the Russian government for its attack on Ukraine, posting: “more sanctions! they destroy hospitals, and a lot of ppl died! even some of my friends !”

Screenshots have appeared of the Conti recovery dashboard and the BazarLoader command and control panel used to control infected devices.

Others claimed that the source code is not the latest version. The leaked code allegedly dates back to September 2020.

Since the initial leaks occurred, various analyses have appeared online detailing the bitcoin addresses used by the group, along with lists of e-mail addresses found it its correspondence. Other information now freely available online includes hundreds of data points detailing domains used in the ransomware’s command and control infrastructure, along with the gang’s active Dark Web chat IDs.
