The Petya Ransomware now bundles a second file-encrypting program for cases where it cannot replace a computer’s master boot record to encrypt its file table. The latest variant of the ransomware program, dubbed Mischa, installs another program that encrypts users’ files directly. The ransom that Mischa currently asks is 1.93 bitcoins, or around US$875 — higher than some similar ransomware programs. There is currently no known way to restore files encrypted by Mischa without paying the ransom.”]
