The Conti Ransomware Leaks
Background
On February 25th 2022 the Conti Ransomware crew declared they support the Russian government:
“The Conti Team is official announcing a full support of Russian government,” the group said in a very aggressive message posted on Friday. “If any body will decide to organize a cyberattack or any war activities against Russia, we are going to use our all possible resources to strike back at the critical infrastructures of an enemy.”
Later on the 25th @FellowSecurity and @vxunderground shared a screenshot of Conti ransomware groups private chatroom and all of their affiliates.
“Little did they know some of their “friends” sided with Ukraine.” - @vxunderground
Two days later on Feburary 27th a Twitter user @ContiLeaks leaked private conti ransomware communications (Jabber chat logs). Over the course of 3 days additional conti data sets were leaked publicly by @ContiLeaks. A full timeline of the leaked data publishing was curated and shared by @ex_raritas
Originally it was suspected that @ContiLeaks was operated by a pro- Ukrainian disgruntled ransomware affiliate.
As further data was leaked it became clear that @ContiLeaks had fully compromised Conti infrastructure and shared details of their root access. Given the extensive access obtained and data leaked, some people have theorized that a government intelligence agency is responsible for the leaks. The security company HoldSecurity reported that the leaks were from Ukrainian Security Researchers:
“Conti’s systems have been infiltrated by cybercrime researchers for some time. The data was dumped by a Ukrainian cyber security researcher pissed off after Conti expressed support for Russia in the conflict.” - @ransomwarefiles
This analysis aims to provide a centralized document with links to other resources and analysis.
“The #conti case will be studied for years to come. Such a diversion. And the criminal underground will fear forever the cyber ghost from Kyiv who took down Top 1 #Ransomware group in the world 🌎” - @ddd1ms
The raw data
Originally the leaked data was posted to the file sharing service anonfiles. Fortunately VX Underground took the effort to archive the data on their website.

“Hello world. Who can help with the lock of the net? Rights raised, data pumped out. Main domain (175serves online) + 2 trusts (~40 serv online). The problem is that everywhere there is a sophos with a password. You can’t find a pass from sophos. Any changes in the settings of sofos are limited, the mount will not be able to lock, although there are cars without AV. You need someone who can cut/stop the sophos. Write in the PM who knows how to deal with sophos.”
