What is Bguu ransomware? And how does it carry out its attack?

Bguu Ransomware

Bguu ransomware is a new crypto-virus that belongs to the HiddenTear ransomware group – an open-source platform used to develop ransomware threats. This new HiddenTear variant uses a “.bguu” extension in marking its encrypted files. Bguu ransomware carries out its attack the same way as other HiddenTear variants. It uses a sophisticated encryption algorithm, RSA 2048, in encrypting its targeted files.

Bguu ransomware starts to carry out its attack by dropping its malicious payload in the system which is the one that initiates a connection to a remote server. Following its infiltration, it alters essential system settings like repressing some system processes so that they can remain undetected. It also modifies some entries in the Windows Registry so it can automatically run every time the computer boots up. Once all system modifications are carried out, it starts its encryption process using the RSA 2048 cipher.

After the encryption, Bguu ransomware appends the .bguu extension on each one of the targeted files, rendering them useless and inaccessible to victims. It then changes the desktop wallpaper of the affected computer and drops a ransom note named “HACKED.txt”. The ransom note is contained in a text file that states:

“All your documents,photos,databases and other important files have been encrypted
with strongest encryption RSA-2048 key, generated for this computer .

Private decryption key is stored on a secret internet server and nobody can decrypted
your files until you pay and obtain the private key .

Warning
You only have 2 days to submit $300 USD of payment .
If you do not send money within the provided time the price will raise to $600 USD


1) The cost of private key for decrypting your files is 0.030 Bitcoin ( $300 USD ) .

2) You can buy bitcoins here : hxxp://www.localbitcoins.com
3) Send 0.030 Bitcoin ( $300 USD ) to : 36X2qqBh3DuUczSym5mMaqE5kdG2yApLuw
4) After you pay 0.030 Bitcoin ( $300 USD ) , send an email to [email protected]
with your transaction ID and i’ll send your private key .”

If your computer ended up getting infected with Bguu ransomware, remember that paying the ransom won’t really give you the solution you’re looking for. In fact, most ransomware victims are ignored by cybercrooks once they receive the payment. The best thing you can do to restore the encrypted files is to use an alternative method to recover them which will be provided in this post.
