Viruses

Oohu Ransomware is a malicious software belonging to the Djvu ransomware family, designed to encrypt files and modify their file names by appending the .oohu extension. This ransomware variant employs the Salsa20 encryption algorithm, making it extremely difficult to decrypt files without the attacker's assistance. After encryption, it generates a ransom message named _readme.txt. The ransom note demands a payment of $490 to $980 in Bitcoin to decrypt the files. However, there is no guarantee that the cybercriminals will provide the decryption key after receiving the payment. If your computer gets infected with Oohu Ransomware, it is advised not to pay the ransom, as there is no guarantee that the cybercriminals will provide the decryption key. Instead, follow our professional guide to remove the ransomware and attempt to recover your files using available tools and methods.

Oopl Ransomware is a variant of the STOP/Djvu ransomware family, which encrypts files on the victim's computer and demands a ransom for their decryption. It is distributed through various methods, such as spam emails with infected attachments, fake software cracks, or by exploiting vulnerabilities in the operating system and installed programs. When Oopl ransomware infects a system, it scans for files like photos, videos, and documents, modifies their structure, and adds the .oopl extension to each encrypted file, making them unusable without the decryption key. For example, it transforms files like 1.jpg into 1.jpg.oopl and 2.png into 2.png.oopl. The ransom note created by Oopl ransomware is named _readme.txt. Oopl ransomware uses the Salsa20 encryption algorithm to encrypt files. Although it is not the strongest method, it still provides an overwhelming number of possible decryption keys, making brute-forcing the decryption key extremely difficult.

Ooza Ransomware is a malicious software that belongs to the Djvu family, which is a part of the notorious STOP/Djvu Ransomware lineage. Its primary objective is to encrypt files on the infected computer, making them inaccessible, and then demand a ransom payment in exchange for the decryption key. Once Ooza Ransomware infects a computer, it encrypts data and adds the .ooza extension to the file names. For example, a file originally named 1.jpg becomes 1.jpg.ooza. The ransomware uses the Salsa20 encryption algorithm. After encrypting the files, Ooza Ransomware creates a ransom note in the form of a text document named _readme.txt. The note provides information about the ransom demand, which ranges from $490 to $980 in Bitcoin, and contact details for the cybercriminals.

Hgew Ransomware is a malicious software that belongs to the STOP/Djvu family of ransomware. It is designed to encrypt files on the infected computer and append the .hgew extension to the filenames, rendering them inaccessible. For example, a file named 1.jpg would be renamed to 1.jpg.hgew. After encrypting the files, Hgew Ransomware generates a ransom note named _readme.txt. The perpetrators provide guidance and contact email addresses (support@freshmail.top and datarestorehelp@airmail.cc) within the ransom note. Hgew Ransomware uses the Salsa20 encryption algorithm to encrypt files on the infected computer. Salsa20 is not the strongest encryption method, but it still provides an overwhelming number of possible decryption keys, making it extremely difficult to brute force the decryption.

AnonTsugumi is a ransomware that encrypts files on the victim's computer, making them inaccessible. It appends the .anontsugumi extension to the filenames of the affected files and changes the desktop wallpaper. The ransomware also provides a ransom note (README.txt) with instructions on how to pay the ransom and recover the encrypted files. The specific encryption algorithm used by AnonTsugumi is not yet known. However, many modern ransomware strains use a combination of AES and RSA encryption to secure their malware. To remove AnonTsugumi ransomware and decrypt the affected files, you can use an automated removal tool or follow a manual removal guide. Automated removal tools can delete all instances of the virus in just a few clicks, while manual removal requires special computer skillsTo remove AnonTsugumi ransomware and decrypt the affected files, you can use an automated removal tool or follow a manual removal guide. Automated removal tools can delete all instances of the virus in just a few clicks, while manual removal requires special computer skills.

Hgfu Ransomware is a file-encrypting malware that belongs to the Djvu malware family. It infiltrates computers and encrypts data, adding the .hgfu extension to file names. For example, a file originally named 1.jpg transforms into 1.jpg.hgfu. In addition to encrypting files, Hgfu generates a ransom note in the form of a text file titled _readme.txt. The distribution of Hgfu may involve information-stealing malware such as Vidar and RedLine. Hgfu Ransomware uses a strong AES-256 encryption key algorithm to encrypt the files of an infected computer system. Cybercriminals often employ these stealers to obtain sensitive information before using Djvu ransomware for data encryption. Upon execution, Hgfu ransomware communicates with a remote server to generate a unique key for the specific computer. After acquiring the key, it starts to encrypt target files using a complex method that is almost impossible to reverse without the decryption key.

Alvaro Ransomware is a malicious software designed to encrypt files on a victim's computer or network, rendering them unusable. It is part of a growing family of ransomware strains known for its complex encryption algorithms and sophisticated distribution tactics. Once it infects a system, it encrypts the victim's files, adding a unique file extension, .alvaro, to distinguish them from the original file. Alvaro Ransomware appends the attackers' email, a unique ID assigned to the victim, and extension to the affected files. For example, a file named 1.jpg would appear as 1.jpg.EMAIL = [alvarodecrypt@gmail.com]ID = [5-digit-number].alvaro. Although the specific encryption algorithm used by Alvaro Ransomware is not known, modern ransomware often uses a hybrid encryption scheme, combining AES and RSA encryption to secure their malware against researchers getting encrypted files back. After the encryption process is completed, Alvaro Ransomware drops a ransom-demanding message titled FILE ENCRYPTED.txt.

Hgml Ransomware is a variant of the Djvu ransomware family, which is known for encrypting files and demanding ransom payments for decryption. It targets various types of files, such as videos, photos, and documents making them inaccessible and unusable without the decryptor. Hgml ransomware uses a powerful encryption algorithm to lock the victim's data. It modifies the filenames by adding the .hgml extension, for example, converting 1.jpg into 1.jpg.hgml. After encrypting the files, Hgml creates a ransom note named _readme.txt that contains instructions for the victim, including the attackers' email addresses (support@freshmail.top and datarestorehelp@airmail.cc) and the ransom amount. Follow the guide below to remove Hgml Ransomware and attempt to decrypt .hgml files for free.
