What is LockCrypt 2.0 ransomware? And how does it carry out its attack?
LockCrypt 2.0 ransomware is a new crypto-virus that was discovered recently. It also happens to be a new variant of the LockCrypt ransomware and uses a combination of AES 256 and RSA 2048 encryption algorithms in locking important files. Once it sneaks into a targeted computer, it plagues various essential system settings to remain undetected. It begins to carry out its attack after its malicious payload is executed. Upon the execution of the malicious payload, LockCrypt 2.0 ransomware also downloads more files some of which are likely to access the Windows Registry so it can achieve persistence on the infected system.
It continues to carry out its attack by starting the encryption process where it applies traditional and unbreakable encryption algorithms, which, as mentioned are AES 256 and RSA 2048. During this phase, it tries to save the encryption keys in the path, “C:\Windows\DECODE.KEY” – if the key file ends up not getting saved properly, recovering the encrypted data would be impossible. After the encryption, this crypto-malware creates a text file named “How To Restore Files.txt” with a ransom message stating:
Your personal id – E3pgw1ofS2
Warning: all your files are infected with an unknown virus.
To decrypt your files, you need to contact at [email protected]
The decoder card is received by bitcoin.
You can buy bitcoins from the following links://blockchain.info/wallet
Do not try to restore files your self, this will lead to the loss of files forever
You can send us 2-3 encoded files.
And attach to the letter a file from the folder c:\Windows\DECODE.KEY for testing, we will return them to you for FREE”
Based on the ransom note, creators of LockCrypt 2.0 ransomware claims they can decrypt files and even offers a free chance to test their decryption tool if you send some encrypted files. However, contacting these crooks is not advised as there is still no guarantee that they’ll decrypt your affected files once they receive the payment. And besides, you can try other alternative ways to recover your files – you can start by checking the path, “C:\Windows\DECODE.KEY” and see if the encryption key is really there or not.
How does LockCrypt 2.0 ransomware proliferate?
Phishing emails still remain to be the most commonly used method in distributing ransomware threats like LockCrypt 2.0 ransomware. Crooks tend to attach a corrupted file which contains malicious scripts used to establish a connection between the remote C&C server of LockCrypt 2.0 and the targeted computer. Once the connection is established, the malicious payload is then dropped in the system. This is why opening emails from unreliable and dubious senders, is not recommended.
