Mischa ransomware is a computer virus that encrypts the files on your computer and then demands a ransom payment of approximately $875 to obtain the decryption key. Mischa ransomware is distributed via malicious emails that claim to consist of job applications. These malicious emails contain a link to a cloud storage service that when clicked will download the ransomware’s installer. The link claims to be a standard PDF file (PDFBewerbungsmappe.exe) that applicants can edit or a PDF resume.
Mischa ransomware is also spread by other ransomware infections. For example, Petya ransomware will install Mischa ransomware on your computer if it initially fails to encrypt the data on your computer.
Once the Mischa virus is contracted it will begin to scan the computer for data files it can encrypt that match the png, jpg, docx, exe, and other file extensions. It will proceed to encrypt the files it locates using the AES encryption algorithm. Then it will append a 4 character extension such as 7GP3 to the filename of the files it encrypts. This means that if your file is named file.exe it will become file.exe.7GP3.
In every folder that Mischa encrypts a file in it will additionally spawn two files named YOUR_FILES_ARE_ENCRYPTED.HTML and YOUR_FILES_ARE_ENCRYPTED.TXT. These are ransom notes that contain information about your files, links to a TOR site to pay the ransom, and a special key that each victim must use on the TOR site. The TOR site consists of a payment wizard that provides additional steps to make the ransom payment and various other pages, including a support page.
