3AM (ThreeAM) Ransomware is a newly discovered strain of ransomware written in Rust programming language. It has been used in limited attacks as a fallback option when the deployment of LockBit ransomware was blocked. The ransomware attempts to stop multiple services on the infected computer before it begins encrypting files and tries to delete Volume Shadow (VSS) copies. 3AM ransomware appends the .threeamtime extension to the filenames of encrypted files. For example, a file named
photo.jpgwould be changed to
photo.jpg.threeamtime. The ransomware creates a ransom note named RECOVER-FILES.txt in every folder containing encrypted files. The note provides information on how to pay the ransom and possibly purchase a decryption tool from the attackers.
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
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.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.jpgwould 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 (firstname.lastname@example.org and email@example.com) 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.
