What is 3301 ransomware? And how does it execute its attack?

3301 ransomware is a malicious threat that encrypts your files in exchange for money. This ransomware is a variant of the Karmen ransomware which belongs to Ransomware as a Service (RaaS) platform used to develop customized ransomware infections. Meaning to say, 3301 is also another customized version of the RaaS platform and currently, it is still unknown who is behind the attacks.
3301 ransomware uses AES 256 encryption algorithm to append the .3301 extension to its targeted files. After the encryption, it creates an html file called DECRYPT_MY_FILES.html which contains the ransom note. Here’s what the message says:
“Ransomware 3301
! Attention !
All your documents, photos, databases
and other important files have been encrypted.
Only way to decrypt your files is to receive the private key and decryption program To receive the private key and decryption program go to any crypted folder inside there is the special file (DECRYPT_MY_FILES.HTML) with complete instructions how to decrypt your files.”
The ransom note will lead you to another html page labeled as You Are Locked by 3301. It suggests that you only have a total of 168 hours or 7 days to pay the ransom and get the decryption key, else you’ll lose your files forever since the crooks claim to delete the decryption key after a week. However, you shouldn’t rush and make the payment right away for there are still other alternative solutions you can try to remove the ransomware and recover your files without having to spend a cent since it’s a fact that even if you pay the ransom, it does not give you an assurance that the crooks will give you the decryption key to get your files back.
