What is Shrug2

Shrug2 ransomware is a threat that offers ShrugDecryptor to recover encrypted data. Shrug2 ransomware is the second version of Shrug ransomware which has been filled with the few new features. The threat is almost identical to the original ransomware. However, the cryptovirus is appending a new file extension and is also using Command and Control server configuration. Like the previous version, Shrug2 relies on AES encryption cipher to lock victim’s files, and, after successful encryption, adds .SHRUG2 file extension as a marker for encrypted data. As a result, users’ data becomes unreadable. Additionally, ransomware places a ransom note on the system which appears in a program window called ShrugDecryptor and states more details about the attack. It claims that the ransom amount is 70 USD which should be paid in Bitcoin. Also, the virus promises to delete data permanently if the ransom is not paid in three days. At the moment, there is no contact email in the ransom note that is advertising the alleged Shrug decryption services.
