Shrug2 ransomware. How to remove? (Uninstall guide)

removal by Lucia Danes - - | Type: Ransomware

Shrug2 ransomware is a file-encrypting virus that that pretends to be from the same family as WannaCry

Shrug2 ransomware
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[1] 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.

Shrug2 ransomware is a malicious crypto-virus that infects your system silently and starts its malicious processes in the background. As the first step, ransomware modifies old or adds new registry keys to make sure that its script is launched everytime your infected device reboots. 

Additionally, Shrug2 virus scans the system and selects which photos, videos, documents or databases to encrypt with a sophisticated AES encryption algorithm. When this file locking is done, the virus places .SHRUG2 file extension. As a result, you can clearly see which files are modified by the threat. 

This silent intruder has been spreading for some time. As a result, Shrug2 can be detected by numerous anti-virus and anti-malware tools as:

  • Artemis!04112AEC4740
  • TR/Ransom.rhagu
  • Generic.Ransom.Hiddentear.A.B8BBD7A8
  • TR/Hiddenrear.agdsy
  • Trojan.Ransom.Shrug
  • Ransom.Genasom!8.293 (CLOUD)
  • TROJ_GEN.R002H09GC18
  • malicious_confidence_70% (D)
  • malware (ai score=97)
  • Win32/Trojan.Hoax.4a4[2] 

When this virus is done with the encryption process, it displays a program window on the screen that looks like a decryption service. The ransom note states that you have 3 days to pay $70 in Bitcoin to a provided wallet. The window is called ShrugDecryptor and contains the following message:

'Ooops! Your files have been encrypted
Are you proud of me,
papa WannaCry?
momma NotPetya?

What happened?
Your important files have been encrypted. Many of your documents, pictures, videos, databases, scripts, codes, presentations are no longer accessible because they have been encrypted.

The first sentences of the ransom note are typically mimicking WannaCry and Petya cyber threats. However, at the moment securoty experts do not find any relation between these cyber threats. If you got infected, you need to remove Shrug2 ransomware as soon as possible. It is important because this ransomware can access various places in the system and modify it according to its developer's commands.

As we have mentioned, this cyber threat is using C&C server configuration helping people behind the virus store your data or control various parts of the device without you knowing that. This additional feature of the ransomware makes it even more dangerous. To prevent the worst case scenario, focus on Shrug2 ransomware removal and get rid of this threat. Use Reimage or other anti-malware tools to scan your device and eliminate all issues hailing from the infection.

Malicious files are typically distributed via infected emails

Malware developers aim to distribute the virus payload widely, so they pretend to send emails from companies like DHL, PayPal or Amazon. Since people often use these services, victims unknowingly open these safe-looking emails and download malicious files. 

Researchers[3] advise you to pay more attention because the minute you download and open the infected file on your computer this malicious ransomware script is planted on the system. These invoices or receipts can look safe but always check for typos and grammar mistakes on the email. This can be an indicator that the email is not legitimate.
