How to remove Proton Ransomware and decrypt .c77l, .ZENEX or .SWIFT files

0
Proton Ransomware is a malicious software designed to encrypt files on a victim's computer, rendering them inaccessible until a ransom is paid. Proton Ransomware is a type of malware that encrypts files on the infected computer, adding specific extensions to the filenames and demanding a ransom from the victim to restore access to the encrypted files. It has been discovered in various forms, with some variants appending extensions such as .c77l, .ZENEX or .SWIFT extensions to the affected files along with emails (.[decrypt.computer@gmail.com].c77L, [decrypthelp0@gmail.com].ZENEX, .[swift_1@tutamail.com].SWIFT). Basically, SWIFT Ransomware and ZENEX Ransomware are just variations of Proton Ransomware. This variations create following ransom note files: #Zenex-Help.txt, #SWIFT-Help.txt or #Restore-files.txt. The ransomware uses AES (Advanced Encryption Standard) and ECC (Elliptic Curve Cryptography) algorithms to encrypt files, ensuring that the encryption is strong enough to prevent unauthorized decryption without the unique key held by the attackers. This article aims to provide a comprehensive overview of Proton Ransomware, including its infection methods, the file extensions it adds, the encryption algorithms it uses, the ransom note it creates, and the possibilities for decryption.

How to remove LockBit 3.0 Ransomware and decrypt encrypted files

0
LockBit 3.0, also known as LockBit Black, is a sophisticated ransomware strain that encrypts data on targeted systems, disrupting access to system and network resources. It is part of a Ransomware-as-a-Service (RaaS) operation, which means it is used by affiliates who deploy it in cyberattacks in exchange for a share of the ransom profits. LockBit 3.0 is known for its fast encryption capabilities and has been active since at least March 2022. During the encryption process, LockBit 3.0 appends a specific extension to encrypted files. This extension can vary, but examples include "HLJkNskOq" and "19MqZqZ0s". The ransomware changes the icons of encrypted files and alters the desktop wallpaper to inform victims of the attack. LockBit 3.0 drops a ransom note, typically named [random_string].README.txt or a similar text file, in every encrypted folder. The note contains instructions for contacting the attackers and paying the ransom, often demanding payment in cryptocurrency.

How to remove RansomHub Ransomware and decrypt your files

0
RansomHub Ransomware is a type of malicious software that falls under the category of file-encryption virus. It is designed to infiltrate computer systems, encrypt files, and demand a ransom for the decryption key. Unlike traditional ransomware, which encrypts files and demands payment, RansomHouse, which is associated with RansomHub, focuses on breaching networks via vulnerabilities to steal data and coerce victims to pay up without necessarily using encryption. RansomHub ransomware may add various file extensions to encrypted files, such as .toxcrypt, .magic, .SUPERCRYPT, .CTBL, .CTB2, .locky, or a 6-7 length extension consisting of random characters. The specific encryption algorithms used by RansomHub are not detailed, but ransomware typically employs strong encryption methods like AES or RSA to prevent unauthorized decryption. RansomHub creates ransom notes with instructions for victims on how to pay the ransom and potentially recover their files. Common ransom note file names include README_{random-string}.txt, and various others. The location of the ransom note is typically within the directories of encrypted files.

How to remove BlackLegion Ransomware and decrypt .BlackLegion files

0
BlackLegion Ransomware is a type of malicious software designed to encrypt files on a victim's computer, rendering them inaccessible, and then demanding a ransom for the decryption key. Once installed on a computer, BlackLegion encrypts files and appends a unique extension to the filenames. Any files encrypted with BlackLegion Ransomware will have a random 8 characters followed by the victim's email and the .BlackLegion extension. For example, a file named photo.jpg might be renamed to photo.jpg.[random-numbers].[Blackdream01@zohomail.eu].BlackLegion after encryption. BlackLegion creates a ransom demand in the form of a text file, typically named DecryptNote.txt or a variant thereof. This note includes instructions on how to pay the ransom, usually in cryptocurrency, and may offer to decrypt a single file for free as proof that the attackers can restore the victim's files.

How to remove WantToCry (NAS) Ransomware and decrypt .want_to_cry files

0
WantToCry Ransomware is a type of encryption virus, which is a subset of malware that encrypts files on a victim's computer and demands a ransom for the decryption key. This particular cryptor targets NAS devices. The WantToCry ransomware appends the .want_to_cry extension to the files it encrypts. This clearly marks which files have been compromised and are inaccessible without the decryption key. While the specific encryption method used by WantToCry is not detailed in the provided source, ransomware generally uses strong encryption algorithms like AES (Advanced Encryption Standard) or RSA (Rivest–Shamir–Adleman) to lock files, making them inaccessible without a unique decryption key. It is a crypto virus that locks files and coerces victims into paying to regain access to their data WantToCry creates a ransom note named !want_to_cry.txt that is left on the victim's computer. This note informs the victim that their data has been encrypted and provides instructions on how to pay the ransom, which is set at $300. Victims are instructed to download and install qTOX, create a profile, and contact the cybercriminals via qTOX chat to arrange payment.

How to remove Mallox Ransomware and decrypt .mallab or .ma1x0 files

Mallox Ransomware, also known as "TargetCompany" or "Fargo," is a malicious software that encrypts files on a victim's computer and demands a ransom for the decryption key. It has been active since mid-2021 and operates under a Ransomware-as-a-Service (RaaS) model, leveraging underground forums and markets to recruit affiliates and advertise its services. Mallox encrypts files using the ChaCha20 encryption algorithm and adds various file extensions to the encrypted files, such as .mallox, .mallab, .ma1x0, .malox, .malloxx, .maloxx, and others. It also uses victims’ names as the extension in some cases. The ransomware drops a ransom note (HOW TO RESTORE FILES.txt) in every directory on the victim's drive, explaining the infection and providing contact information for the attackers. The note instructs victims to send their personal ID to the attackers' email address to receive payment instructions for the decryption tool.

How to remove Press Ransomware and decrypt .press, .dwarf or .spfre files

0
Press Ransomware is a type of malware that falls under the category of crypto-ransomware, which is designed to encrypt data on infected computers, rendering the files inaccessible to the users. The attackers then demand a ransom payment in exchange for the decryption key that would allow the victims to regain access to their encrypted files. After encrypting the files, Press Ransomware appends .press, .dwarf or .spfre extensions to the filenames, making them easily identifiable. For example, a file originally named 1.jpg would be renamed to 1.jpg.press after encryption. The specific encryption algorithm used by Press Ransomware is not detailed in the provided search results, but it is common for such malware to use robust encryption methods like AES or RSA to prevent unauthorized decryption. Upon completion of the encryption process, Press Ransomware drops a ransom note named RECOVERY NFO.txt on the victim's computer. This note informs the victim that their files have been encrypted and that sensitive data has been exfiltrated. The attackers threaten to sell or leak the stolen content online if the ransom is not paid. The note also offers the victim the opportunity to send a couple of encrypted files to the attackers for free decryption as proof that they can decrypt the files.
