How to remove TUGA Ransomware and decrypt .TUGA files

0
TUGA Ransomware is a type of malware that encrypts files on a computer and demands a ransom to decrypt them. It is often spread through phishing emails that contain malicious attachments or through drive-by downloading, which occurs when a user unknowingly visits an infected website and then malware is downloaded and installed without the user’s knowledge. Once infected, TUGA Ransomware encrypts all user’s data on the computer, including images, documents, excel tables, audio files, videos, etc., and appends its own extension to every file (.TUGA), leaving the README.txt files in each folder with the encrypted files. The ransom note left by TUGA is created to inform victims that their systems have been compromised. The note includes a link to the Telegram channel t.me/hell2cat to communicate with the hackers. They demand a payment of $1000 in exchange for providing the decryption key to regain access to the encrypted files.

How to remove Tghz Ransomware and decrypt .tghz files

0
Tghz Ransomware is a type of malware that encrypts files on a computer and demands payment in exchange for the decryption key. It belongs to the Djvu/STOP ransomware family, which is known for its wide distribution and high infection rates. Tghz Ransomware encrypts various file types, such as documents, images, and videos, and adds the .tghz extension to the affected files. It uses the Salsa20 encryption algorithm, which is not the strongest method, but still provides an overwhelming amount of possible decryption keys. To brute force the 78-digit number of keys, you need 3.5 unvigintillion years (1*10^65), even if you use the most powerful regular PC. Once the encryption process is complete, Tghz Ransomware conveniently leaves a ransom note named _readme.txt. The ransom note provides payment information and the threat, including how to send payment, how much you need to pay, and what happens if you don't pay. The ransom amount ranges from $490 to $980 (in Bitcoins).

How to remove Bhtw Ransomware and decrypt .bhtw files

0
Bhtw Ransomware is a new variant of the STOP/Djvu ransomware family that encrypts files and adds the .bhtw extension to their names. This way, after encryption file, for example 1.doc will get a suffix and will become 1.doc.bhtw. The ransomware is distributed via spam email containing infected attachments, fake software cracks, or by exploiting vulnerabilities in the operating system and installed programs. Once the ransomware infects a computer, it encrypts all popular file types, including videos, images, documents, audio files, and archives. After encryption, it generates a ransom note in the form of a text file named _readme.txt. The ransom note contains instructions on how to pay the ransom to get the decryption key.

How to remove Udaigen Ransomware and decrypt .jcrypt files

0
Udaigen Ransomware is a type of malware that encrypts files and demands payment for decryption. It adds its specific extension .jcrypt, to every file it encrypts. Unfortunately, there are no known decryption tools for Udaigen Ransomware at this time. The encryption method used by this ransomware is currently unknown. To prevent further encryption by Udaigen ransomware, it is essential to remove it from the operating system. However, removing the ransomware will not restore the compromised files. The only solution is to recover the files from a previously created backup stored in a different location. We highly recommend storing backups in multiple separate locations, such as remote servers or unplugged storage devices, to prevent permanent data loss. Malware creates ransom note ___RECOVER__FILES__.jcrypt.txt and displays pop-up window with information to contact the hackers.

How to remove Bhgr Ransomware and decrypt .bhgr files

0
Bhgr Ransomware is a file-encrypting virus and a variant of the STOP/Djvu ransomware family. It encrypts files and appends the .bhgr extension to their original filenames. It uses advanced RSA and AES encryption algorithms to lock files of infected PCs, making it impossible to unlock files without knowing the unique private decryption key generated by the computer. Unfortunately, at this time, there are no decryption tools available for Bhgr Ransomware. However, Emsisoft provides free ransomware decryption tools that may work with specific ransomware versions. Bhgr Ransomware generates a ransom note in the form of a text file named _readme.txt. The ransom note contains instructions on how to pay the ransom in exchange for a decryption key that can unlock the encrypted files.

How to remove Bhui Ransomware and decrypt .bhui files

0
Bhui Ransomware is a type of malware that encrypts files on a victim's computer and demands payment in exchange for a decryption key. Bhui ransomware is part of the STOP/Djvu ransomware family and is spread through malicious files disguised as freeware, key generators, and hacked games, which are commonly found on file-sharing and torrent sites. Once installed, Bhui encrypts all files on the victim’s computer, adding the .bhui extension to the filenames. For example, a file named 1.jpg gets renamed to 1.jpg.bhui, and 2.png becomes 2.png.bhui. Bhui ransomware encrypts files using a strong encryption algorithm called Salsa20. The encryption algorithm is complex and makes it difficult to decrypt files without the decryption key. In addition to file encryption, Bhui generates a ransom note, a text file called _readme.txt. The ransom note emphasizes that file decryption is only possible with the use of specific decryption software and a unique key.
