The Petya ransomware, a particularly vicious threat, has reared its ugly head once again; only this time, it’s not alone. Petya now comes bundled together with Mischa, another ransomware that works well alongside Petya. The ransomware is delivered via an inconspicuous email disguised as a job application, with a resume attached. Once the user downloads the file, Petya encrypts the files on the device.
