Working of Petya ransomware

Petya Ransomware is not like any traditional ransomware. It does not encrypt all file simply. First it reboot the computer & encrypt the Hard Disk complete Master File Table & destroys the MBR (Master Boot Record).
The MBR is replaced with another malicious code into the PC & there is no way to boot PC then. The file system which information like  file names, sizes, and location are locked on the physical disk.
In the beginning Kaspersky told that the ransomware is a variant of old Petya ransomware but later said the infection is based on the whole new infection & call it ‘NotPetya’.

  1. Avira & symantec has claimed that Petya is based on Eternal Blue exploit, same as WannaCry.
  2. Eternal Blue exploit attacks Windows SMB file sharing system & spreads fast between different systems.

After the infection your PC will show the message “If you see this text, then your files are no longer accessible because they are encrypted. Perhaps you are busy looking for a way to recover your files, but don’t waste your time. Nobody can recover your files without our decryption service.”

    “You’re buying into belief in the value of a currency backed by nothing — no banks, no governments, no property. Cryptocurrency advocates will tell you that’s why it’s so great””
    No thats not at all what cryptocurrency advocates will say – they will say you are clueless to claim its backed by nothing. Its not fiat currency. Fiat currency is backed by nothing – cryptocurrency is backed by verified proofing systems and public ledgers that cannot be forged or altered”
