Creators of the rival Petya and Mischa ransomware programmes have leaked the private keys of Chimera ransomware.
According to Mischa developers, they gained access to large parts of the system used by Chimera's creators earlier this year and as a result obtained Chimera's source code and integrated some of it into their own project.
Malwarebytes spotted the leak and reported that Mischa shares some components with Chimera. There is no confirmation that the newly leaked RSA keys actually work to decrypt files affected by Chimera.
“Checking if the keys are authentic and writing a decryptor will take some time – but if you are a victim of Chimera, please don't delete your encrypted files, because there is a hope that soon you can get your data back,” Malwarebytes researchers said.
