How to remove BackMyData Ransomware and decrypt .backmydata files

0
BackMyData Ransomware is a malicious software variant belonging to the Phobos family, identified for its capability to encrypt files on infected computers, thereby rendering them inaccessible to users. It targets a wide range of file types, encrypting them and appending the .backmydata extension along with the victim's ID and an email address ([backmydata@skiff.com]) to the filenames. This renaming makes the files easily identifiable but inaccessible without decryption. The specific encryption algorithm used by BackMyData is not explicitly mentioned, but like other ransomware variants in the Phobos family, it likely employs strong encryption methods that make unauthorized decryption challenging without the necessary decryption keys. BackMyData generates two ransom notes named info.hta and info.txt, which are placed on the victim's desktop. These notes contain messages from the attackers, instructing victims on how to contact them via email (backmydata@skiff.com) and demanding a ransom payment in exchange for decryption keys. The notes also threaten to sell stolen data if the ransom is not paid, emphasizing the urgency and seriousness of the situation.

How to remove Lkhy Ransomware and decrypt .lkhy files

0
Lkhy Ransomware is a variant of the notorious STOP/DJVU ransomware family that encrypts files on infected computers, appending the .lkhy extension to the filenames. It uses the Salsa20 encryption algorithm to lock files, making them inaccessible to users. Once the encryption process is complete, LKHY drops a ransom note named _readme.txt, demanding payment in Bitcoin to allegedly send a decryption key. LKHY ransomware targets specific file types, such as documents, images, videos, and databases, using a symmetric AES algorithm. It generates a unique encryption key for each file and deletes the original files, leaving only the encrypted versions. The ransom note demands payment ranging from $499 to $999 in Bitcoin, with a 50% discount if the victim contacts the attackers within 72 hours. The ransom note is typically found in every folder containing encrypted files.

How to remove Jackpot Ransomware and decrypt .coin files

0
Jackpot is a type of ransomware, a malicious software that encrypts files on a victim's computer and demands a ransom for their decryption. It was first seen in early 2020. The ransomware is known to modify the Windows Registry editor, change the wallpaper, and notify the victim about the infection. During the encryption process, Jackpot Ransomware appends the .coin extension to all compromised files. For example, a file named 1.jpg would appear as 1.jpg.coin. The specific encryption algorithm used by Jackpot Ransomware is not specified in the search results. After the encryption process is complete, Jackpot Ransomware creates ransom messages in payment request.html and payment request.txt files on the desktop. The ransomware also locks the device's screen with a message identical to those in the ransom-demand .html and .txt files.

How to remove LockShit BLACKED Ransomware and decrypt .KJHEJgtkhn files

0
LockShit BLACKED Ransomware is a type of malicious software that targets companies worldwide, encrypting their data and demanding a ransom for the decryption key. It is known for its aggressive tactics, including threatening to repeatedly attack a company if the ransom is not paid. The ransomware changes the desktop wallpaper and creates a ransom note named KJHEJgtkhn.READMEt.txt to provide victims with instructions on how to proceed. Once a computer is infected, LockShit BLACKED ransomware appends a unique extension to the encrypted files, which is .KJHEJgtkhn. The specific encryption algorithm used by LockShit BLACKED is not detailed in the provided sources, but ransomware typically employs strong encryption methods like AES or RSA, making it difficult to decrypt files without the corresponding decryption key. The ransom note informs victims that their data has been stolen and encrypted. It warns against deleting or modifying any files, as this could lead to recovery problems. The note also includes a link to a TOR website where the ransom payment is presumably to be made.

How to remove Ldhy Ransomware and decrypt .ldhy files

Ldhy Ransomware is a type of malicious software that falls under the category of crypto-ransomware. It is designed to infiltrate Windows systems, encrypt files, and demand a ransom for the decryption key. This article aims to provide an informative overview of Ldhy Ransomware, its infection methods, the encryption it uses, the ransom note it generates, and the possibilities for decryption. Once Ldhy Ransomware has infiltrated a system, it targets and encrypts a wide range of file types, including documents, images, and databases, using the Salsa20 encryption algorithm. This algorithm is known for its strong encryption capabilities, making brute-forcing the decryption keys practically impossible. After encrypting the files, LDHY appends a .ldhy extension to the filenames, signaling that the files have been compromised. Ldhy Ransomware creates a ransom note named _readme.txt, which is typically placed on the victim's desktop. The note informs the victim that their files have been encrypted and that recovery is only possible by purchasing a decrypt tool and a unique key from the attackers. The ransom demanded can range from $499 to $999, payable in Bitcoin, with a 50% discount offered if the victim contacts the attackers within 72 hours.
