By | Posted on September 4, 2019 |

Peta is a computer virus that is actually another edition of ransomware from STOP family of malware. The objective for creating such infectious code is to force victims to pay a huge ransom demand in order to make their encrypted files accessible once more. The idea of cyber criminals in applying a complex encryption algorithm to user’s data has been one of their favorite ways to easily generate revenue and Peta virus is just one of the so many ransomware currently flooding the internet.

The Peta ransom virus has sneaky ways to penetrate a computer undetected. Once inside and all of necessary processes are loaded, it searches the local storage for common files like documents, photos, images, videos, spreadsheets, archives, databases, drawings, and so on. Its next move is to use a hybrid crypto-system to render the files garbled or unusable. Other than this obscure method, all infected data will obviously exhibit .peta file extension, which only denotes that no programs can successfully open it. Peta ransomware wants computer users to know about this progressing attack and therefore, it will leave a ransom note on the same exact folder as encrypted files.

The documents state that victims will have to pay attackers a hefty $980 if they want to restore .peta files back to their original format. Payment can be trimmed down to half of the original price if victims can make the transaction within the 72 hours period from the time of initial attack.
