Ransomware

Nztt Ransomware is a dangerous malware variant belonging to the STOP/Djvu family. Once installed, Nztt encrypts files using a strong encryption algorithm and appends the .nztt extension to the filenames. For example, a file named 1.jpg would become 1.jpg.nztt. The ransomware then generates a ransom note as a text file. Nztt Ransomware targets various file types, including images, videos, audio, documents, and databases. It uses a powerful encryption algorithm to lock files and make them inaccessible without a decryption key. The primary motive of the creators is to extort money from users in return for the decryption tool. The ransom note found within the _readme.txt file informs victims that decrypting files relies on specialized decryption software and a unique key. It also provides instructions on how to use the file encryption method and recover access to the encrypted data. The ransom demanded by the cybercriminals ranges from $490 to $980 in Bitcoin.

Nzqw Ransomware is a member of the Djvu family, which encrypts a range of files on compromised computers and appends the .nzqw extension to their original filenames. It typically infects computers via unsafe websites, where users may download cracked games, pirated software, or other similar files. The ransomware uses AES+RSA encryption methods to render files inaccessible. Nzqw Ransomware creates a ransom note in the form of a text file named _readme.txt. The note emphasizes that the decryption process relies on specialized decryption software and a unique key. The ransom demanded is usually $980 for the decryption key and software. In the event of an infection, it is crucial to remove the ransomware using a professional anti-virus program before attempting any data recovery techniques. After removing the ransomware, you can try using data recovery software or restoring your files from a backup if you have one. However, there is no guarantee that these methods will successfully recover your encrypted files.

Wzer Ransomware is a malicious program that belongs to the STOP/Djvu family of ransomware. It targets various types of files, such as photos, videos, and documents, encrypting them and appending the .wzer extension to each file. This makes the files inaccessible and unusable without the corresponding decryption key held by the attackers. The malware encrypts files using complex cryptographic algorithms, making them unreadable and inaccessible. Wzer Ransomware leaves a ransom note in the form of a _readme.txt file on the victim's desktop. The note provides information about the encrypted files and demands a ransom payment in Bitcoin to decrypt the files.

Wzoq Ransomware is a file-encrypting malware that belongs to the notorious STOP/DJVU ransomware family. Its primary purpose is to restrict access to data, such as documents, images, and videos, by encrypting files. Once the Wzoq ransomware infects a system, it encrypts files and appends the .wzoq extension to each encrypted file, making them unusable without the decryption key. For example, a file initially named 1.jpg would become 1.jpg.wzoq after falling prey to this malicious software. The ransomware then attempts to extort money from victims by demanding a ransom in exchange for a decryption key that can allegedly restore access to the encrypted files. After encrypting the files, Wzoq ransomware drops a ransom note named _readme.txt on the desktop.

Wztt Ransomware is a malicious software that encrypts various files on a victim's computer and adds the .wztt extension to their filenames, making them inaccessible. For example, it renames 1.jpg to 1.jpg.wztt and 2.png to 2.png.wztt. It is a variant of the STOP/DJVU malware group, which exploits vulnerabilities in a user's computer system and demands a ransom in exchange for the recovery and decryption of the encrypted files. The ransomware generates a ransom note, typically placed on the victim's desktop, named _readme.txt that provides a pair of email addresses (support@freshmail.top and datarestorehelp@airmail.cc) for the victims to contact within a 72-hour timeframe to avoid the ransom fee increasing to $980. Wztt Ransomware employs a strong encryption algorithm and a key (either an 'offline key' or an 'online key') to encrypt the files. It attempts to encrypt as many files as possible, encrypting only the first 154kb of the contents of each file to speed up the encryption process.

FreeWorld is a type of ransomware, specifically categorized as a crypto virus or files locker. Ransomware is a malicious software that encrypts files on a victim's computer and demands payment for decryption. It is designed to infect the Windows operating system and encrypt files using advanced military-grade technologies. FreeWorld Ransomware uses a hybrid encryption scheme, with a combination of AES and RSA encryption to secure their malware against the researchers getting encrypted files back. When the FreeWorld ransomware infects a system, it encrypts the victim's files and appends a .FreeWorldEncryption extension to their filenames. After encryption, it creates a ransom note named FreeWorld-Contact.txt. The ransom note explains that the victim's data has been encrypted and provides instructions for contacting the attackers to initiate the data recovery process.

Wzqw Ransomware is a type of malware that belongs to the Djvu family. It encrypts various files on a victim's computer and adds the .wzqw extension to their initial filenames. The encryption is done using the AES-256 algorithm (CFB mode) encryption algorithm. Once the encryption is successful, the users are unable to access their files without the decryption key. The ransom note, located within the _readme.txt file, underscores that the process of decrypting files solely relies on specialized decryption software and an exclusive key. The ransom note also demands a ransom payment in Bitcoin from the victims, which ranges from $490 to $980, depending on the time passed after the attack. The note instructs the victim to make payment for decryption using Bitcoins, with the ransom amount contingent on the speed of response. Once payment is made, the decryption tool will be provided to unlock the encrypted files. As a guarantee, the note suggests that the victim can send up to 5 files for free decryption. The total size of these files should not exceed 4 MB, and they should not contain valuable data such as databases, backups, or large Excel sheets.

Jaoy is a new version of notorious STOP/Djvu Ransomware, that is known to be the most widespread ransomware in history. Jaoy Ransomware encrypts files using a strong AES-256 encryption key algorithm. This encryption method is widely used and considered to be very secure. It is unlikely that victims will be able to decrypt their files without the decryption key provided by the attackers. Virus adds the .jaoy extension to the end of all encrypted file names. For example, a file named document.docx would become document.docx.jaoy after being encrypted by the ransomware. The ransom note created by Jaoy Ransomware is named _readme.txt and is left in all the folders containing encrypted files. The note demands a ransom of $490 to $980 and provides two email addresses for contact.
