The creators of the Petya and Mischa ransomware programs leaked about 3,500 RSA private keys. The keys are believed to belong to systems infected with Chimera, another ransomware application. There’s no confirmation yet that the newly leaked RSA keys actually work to decrypt files affected by Chimera.
