Malwarebytes, an internet security company, already confirmed this fact in their report last month where they said Mischa shares “some components” with Chimera.
There’s no official confirmation yet that the leaked RSA keys would actually work in decrypting the files in Chimera-infected systems, however, there’s a big chance that they are legitimate. Malwarebytes researchers made this statement in their blog post:
“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.”
Chimera appeared in November, and it differs from other types of ransomware; it threatens the victims
