Ransomware

Wisz Ransomware is a type of malware that encrypts files on the victim's computer, appending the .wisz extension to the filenames. It targets personal photos, documents, databases, and other critical files, making them inaccessible without a decryption key, which the attackers offer in exchange for a ransom payment. Upon infection, Wisz Ransomware initiates a robust encryption process using the Salsa20 encryption algorithm. It scans the system for high-value files and encrypts them. This encryption renders the files inaccessible to the victims. After encrypting the files, WISZ ransomware drops a ransom note named _readme.txt in the directories containing encrypted files. This note includes instructions for contacting the attackers via email and the ransom amount, typically demanded in Bitcoin. The ransom usually ranges from $499 to $999, with a discount offered for prompt payment. This article provides an in-depth analysis of WISZ ransomware, including its infection methods, encryption techniques, ransom demands, and potential decryption solutions.

Lkfr Ransomware is a variant of the STOP/DJVU ransomware family, known for its malicious file encryption operations. Once it infiltrates a system, it targets various file types, encrypting them and appending the .lkfr extension, rendering them inaccessible without a decryption key. The ransomware demands a ransom payment in Bitcoin, typically ranging from $499 to $999, in exchange for the decryption key. After encryption, LKFR ransomware displays a ransom note named _readme.txt with payment instructions, demanding payment in Bitcoin to provide a decryption key. The note typically includes contact information and a unique ID for the victim. Lkfr Ransomware represents a significant threat due to its robust encryption tactics. Victims should focus on prevention, use reputable security solutions, and maintain regular offline backups to mitigate the impact of such ransomware attacks. If infected, it is crucial to remove the ransomware from the system and explore all available options for file recovery without succumbing to ransom demands.

2023Lock is a ransomware that has recently targeted companies, encrypting their data and demanding payment for decryption. This article aims to provide an informative, preventive, and recovery-focused perspective on this malicious software. Once installed, it encrypts files and appends the .2023lock extension to their names. The ransomware uses sophisticated encryption algorithms, making it difficult to decrypt files without the attackers' involvement. After encryption, 2023Lock creates two ransom notes, README.html and README.txt, which are dropped into the C drive. These notes inform the victim that their files have been encrypted and sensitive data stolen, urging them to contact the cybercriminals within 24 hours. The ransom note also warns against using third-party decryption tools, as they may render the affected data undecryptable. 2023Lock ransomware is a severe threat that can cause significant damage to your data. To protect yourself, maintain regular backups, keep your security software up-to-date, and exercise caution when handling email attachments or downloading files. If you are infected, do not pay the ransom, as there is no guarantee of file recovery. Instead, focus on removing the ransomware and restoring your data from a backup.

Dalle Ransomware is a high-risk infection that is part of the Djvu ransomware family. It was first discovered by malware researcher Michael Gillespie. The primary function of Dalle is to infiltrate computers stealthily and encrypt most stored files, rendering them unusable. During the encryption process, Dalle appends the .dalle extension to the filenames. The exact encryption algorithm used by Dalle is unconfirmed, but it is known that each victim receives a unique decryption key stored on a remote server controlled by the ransomware developers. Dalle creates a ransom note named _readme.txt and places a copy in every folder containing encrypted files. The note informs victims that their files are encrypted and demands a ransom payment to decrypt them. The initial ransom amount is $980, with a 50% discount offered if contact is made within 72 hours, reducing the cost to $490. The main purpose of the article is informational, aiming to educate readers about the Dalle Ransomware, its infection methods, the encryption it uses, the ransom note it creates, and the possibilities for decryption, including the use of tools like the Emsisoft STOP Djvu decryptor.

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.

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.

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.

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.
