Another ransomware is out and making its comeback, causing havoc to many users. This latest ransomware is called Petya ransomware. Petya functions as a ransomware-type of infection which was first discovered in 2016. Apparently, its developers decided to recover and release the ransomware by the end of June, 2017 and since then had attacked 12,000 machines over 65 countries. This ransomware came from Russia. Its first attack since coming back, originated from Ukraine and started spreading on June 18, 2017 or earlier than that. The Petya ransomware has already affected several companies like Rosneft, Maersk, Saint-Gobain, banks like the National Bank of Ukraine, and more.

Petya ransomware is also known as PetrWrap, GoldenEye ransomware, Mamba virus and Mischa ransomware, although the newly recovered Petya ransomware starts to behave like the WannaCry ransomware and that spoke volumes knowing how fatal the WannaCry is. Once Petya infects your computer, it won’t encrypt your files one by one but reboots your computer first and displays the screen shown above. It then starts to encrypt the Master File Table (MFT) of your hard drive that causes the Master Boot Record (MBR) to stop operating. When that happens, the Petya virus silently carries out the encryption process in your system’s background. Once the encryption is done and you try to reboot your computer, a flashing skeleton will appear together with the text, “PRESS ANY KEY”. After you press the key, another window opens containing the ransom note.

 

The ransom note asks the user to pay 0.9 BitCoin which is around $400, however it was changed to $300 in BitCoin. So the ransom amount could be different for each victim. The Petya ransomware uses a very complex algorithm which is RSA-4096 and AES-256 in encrypting files. These complicated algorithms are impossible to decrypt without the decryption key which is located somewhere on a remote server that is only accessible to the developers of Petya.

You can get infected with this dangerous ransomware after downloading a fake office document usually found on spam emails. According to our researchers, the Petya ransomware uses the SMBv1 vulnerability which was also used by the WannaCry ransomware to spread out its infection. And after a series of test, they’ve found out that if you create a text file entitled, perfc and place it in C:Windows folder, the Petya ransomware removes itself once it detects that file on your computer. Strange right? But it is worth the shot and besides, prevention is always better than cure so to protect yourself from the wrath of this ransomware create the perc file and make sure you have an excellent antivirus and anti malware program in your computer like Spy Remover Pro.
