How to remove SophosEncrypt Ransomware and decrypt .sophos files

0
SophosEncrypt is a new ransomware-as-a-service (RaaS) that has been disguising itself as the well-known cybersecurity provider Sophos, thus masking its true identity and intentions. The ransomware encrypts files on the infected system using a complex encryption algorithm, making data useless on the infected system. It affects commonly used data such as pictures, documents, videos, databases, and archives. The ransomware appends a unique machine identifier, the email address entered during setup, and the suffix .sophos to every file it encrypts. Cybersecurity researchers have uncovered that the ransomware encryptor is written in Rust and uses the C:\Users\Dubinin path for its crates. However, it is still unclear how the ransomware is being promoted and distributed. Most modern ransomware uses strong encryption methods such as RSA-2048 or AES-128, making it impossible to get your files back unless you have the decryption key. It is still unclear which encryption method SophosEncrypt uses. The ransomware creates a ransom note (information.hta) for every folder with encrypted files, and replaces the impacted device's wallpaper to show a message indicating system-wide data encryption with the Sophos logo.

How to remove Mitu Ransomware and decrypt .mitu files

0
Mitu Ransomware is a type of malware that encrypts the files on a victim's computer, rendering them unusable. Mitu is a harmful file encryption virus that uses a strong AES-256 encryption key algorithm to encrypt the files of an infected computer system. Like other ransomware, Mitu Virus also overtakes your confidential data and asks for a ransom from the victim. It is marketed as a useful app in online advertisements, on social media, and in emails. The Mitu ransomware attack is launched when the computer user downloads and installs the program. It begins by connecting to a remote server in order to download more malicious files. Additionally, it awaits instructions and the private key from the distant computer that was set up to maintain the encryption process. When the Mitu ransomware infects files, it adds a distinctive .mitu suffix to them, making them inaccessible and unusable without a specific decryption key. Once the encryption process is concluded, Mitu creates a ransom note titled _readme.txt.

How to remove Miza Ransomware and decrypt .miza files

0
Miza Ransomware is a dangerous virus that encrypts files on infected computers and demands payment (usually on cryptocurrency) for their decryption. It is part of the Djvu ransomware family and is known for its wide distribution and high infection rates. The virus encrypts files by appending a .miza extension to the original filename. For example, a file photo.jpg will get changed into photo.jpg.miza after this ransomware attack. Upon successful transformation of files, a ransom note _readme.txt is dropped in all compromised folders. Miza ransomware uses a strong encryption algorithm called Salsa20 to encrypt victim's files. The encryption process is almost unbreakable, making it difficult to recover files without the decryption key. The encryption technique employed by Miza Ransomware is a critical factor in its effectiveness. However, detecting the encryption process can be challenging due to its minimal and often unnoticed symptoms, such as occasional spikes in RAM and CPU usage.

How to remove DEADbyDAWN Ransomware and decrypt .OGUtdoNRE files

0
DEADbyDAWN is a type of ransomware that encrypts files and alters their names by replacing them with a random string of characters and appending its unique extension. The ransomware drops fifty text files onto the desktop, labeled sequentially from README0.txt to README50.txt. Each of these files contains an identical ransom note. It is important to note that different samples of DEADbyDAWN append different extensions to filenames. DEADbyDAWN alters file names by replacing them with a random string of characters and appending its unique extension (.OGUtdoNRE). Different samples of DEADbyDAWN may append different extensions to filenames. DEADbyDAWN uses encryption to render files inaccessible. The encryption method used by DEADbyDAWN is not specified or yet unknown. The sample of the ransom note is presented in the text box below.

How to remove Miqe Ransomware and decrypt .miqe files

0
Miqe Ransomware is an advanced encryption virus that enciphers files on a victim's computer and demands payment in exchange for a key and a decryptor that can restore access to the files. The virus is part of the Djvu ransomware family. The ransom note, _readme.txt, informs victims that the only way to recover the compromised data is by purchasing the decryption key and software from the attackers. The ransom demand starts at $980, and victims are given a 50% discount if they pay within 72 hours. In order to separate the data from any installed applications, the virus appends the data with the .miqe file extension as it encrypts it. The encrypted files can only be decrypted with the appropriate key, which is held by the attackers. Miqe ransomware attacks are often carried out by sophisticated cybercriminals who employ advanced encryption techniques and tactics, making it challenging to decrypt the files without the encryption key. During the encryption process, a file named *.key (previously .key.) is created in the root directory (C:\ or /root/). Required for decryption, this key file only exists on the machine where it was created and cannot be reproduced. The STOP Djvu ransomware encrypts victim's files with Salsa20, and appends one of dozens of extensions to filenames.

How to remove NURRI Ransomware and decrypt .NURRI files

0
NURRI Ransomware is part of the Phobos ransomware family. Like other representatives of Phobos ransomware, this virus encrypts files aside from locking a system and demands payment from affected users in exchange for a decryption key to unlock the encrypted files. The ransomware appends the .NURRI extension to filenames and provides two ransom notes (info.hta and info.txt). The ransom note states that all files have been encrypted due to a security problem with the user's PC. The virus encrypts files using a strong encryption algorithm and a key (‘offline key’ or ‘online key’). It tries to encrypt as many files as possible, for this it only encrypts the first 154kb of the contents of each file and thus significantly speeds up the encryption process. NURRI has the ability to encrypt files on all drives connected to the computer: internal hard drives, flash USB disks, network storage, and so on.

How to remove Gaqq Ransomware and decrypt .gaqq files

0
Gaqq Ransomware is a dangerous malware that can cause significant damage to your computer and files. It is a type of virus or malware that strongly encrypts important files on a victim's computer, making them inaccessible until a ransom is paid. The ransomware belongs to the STOP/Djvu malware family, which is known for its harmful activities. Gaqq Ransomware appends the .gaqq extension to the name of each locked file. It employs a sophisticated encryption technique to lock files, using a combination of Salsa20 and RSA-4096 encryption algorithms. Once the ransomware infects a device, it creates a text file named _readme.txt on the infected device, which contains instructions from the operators of the Gaqq Ransomware. The ransom note demands a specific payment for the decryption key, which can range from $490 to $980.

How to remove Waqq Ransomware and decrypt .waqq files

0
Waqq Ransomware is a type of malware that encrypts files stored on the compromised device and subsequently demands a ransom from its victims. It belongs to the Djvu Ransomware family and encrypts files using an RSA encryption cipher. Once the encryption process is finalized, Waqq appends its own extension (.waqq) to the original filenames. Subsequent to the encryption, the ransomware deposits a ransom note in the form of a _readme.txt file containing instructions on how to make the ransom payment. The ransom note provides two email addresses (support@freshmail.top and datarestorehelp@airmail.cc) and directs victims to contact them within a 72-hour window to prevent the ransom. In this articles we feature tools that will help you remove Waqq Ransomware and all possible solutions to decrypt .waqq files using standard Windows tools or third party decryption and file-recovery utilities.
