Conti Ransomware Gang Chats Leaked After Pro-Russia Threats
The Conti ransomware operation faced a major internal data leak after publicly backing Russia during the invasion of Ukraine and warning it would use its “full capacity” to retaliate against Western cyberattacks on Russian critical infrastructure. Researchers and media reports said activists released roughly 60,000 internal messages, reportedly from the gang’s Jabber server, exposing more than a year of conversations and offering an unusually detailed view into one of the most prolific ransomware groups tied to Russia.
The leaked chats were described as shedding light on Conti’s internal structure, tactics, and past operations, including activity linked to high-profile incidents such as the attack on Ireland’s public health service. Reporting also highlighted Conti’s use of the ProxyShell exploit in attacks against healthcare targets and the deployment of scripts to disable Windows Defender before encryption. The fallout appeared to ripple across the cybercrime ecosystem, with rival ransomware group LockBit publicly distancing itself from geopolitics and emphasizing that it was motivated by profit rather than allegiance to any state.

How this story unfolded
5 events from the most recent confirmed update back to the earliest known activity.
Researchers report Conti resumed operations after leak disruption
By early March, multiple security firms assessed that the Conti ransomware gang had quickly recovered from the late-February chat leaks and was again conducting breaches, phishing activity, command-and-control operations, and posting new victim data. Analysts said the leak caused only brief disruption and was unlikely to dismantle the group without law enforcement action.
Second leak exposes Conti ransomware source code and tools
A follow-on leak exposed screenshots of Conti storage servers, the BazarBackdoor API, and the source code for the gang's ransomware encryptor, decryptor, and builder. The disclosure reportedly occurred after a password-protected archive was cracked, expanding the earlier leak beyond internal chat logs.
Researchers begin analyzing leaked Conti chats
Security researchers and vendors began reviewing the leaked chat archive and publishing early findings about Conti's structure, tactics, and operations. The disclosures highlighted the leak's significance for understanding the ransomware group's internal workings.
Activists leak Conti's internal chat logs
After Conti's pro-Russia statement, activists leaked roughly 60,000 internal Conti messages, reportedly from Jabber and spanning about 13 months. Researchers said the leak offered rare insight into the gang's internal operations and past attacks.
Conti threatens retaliation over cyberattacks on Russia
Conti published a statement warning it would use its "full capacity" to retaliate if the US or its allies launched cyber operations against Russia or targeted Russian critical infrastructure during the Ukraine conflict. The group also said it was not formally allied with the Russian government while signaling support for Russia.
