Viruses

Keylock Ransomware is a type of malicious software that encrypts files on a victim's computer and appends a .keylock extension to the filenames. For example, a file originally named 1.jpg would appear as 1.jpg.keylock after encryption. Once the encryption process is completed, Keylock creates a ransom-demanding message titled README-id-[username].txt (filename varies based on the username). The ransom note provides instructions on how to pay the ransom, usually in Bitcoin, to obtain the decryption key and regain access to the encrypted files. Keylock ransomware uses AES encryption, a symmetric encryption algorithm, to encrypt files quickly. The ransom note warns against renaming, modifying, or deleting the encrypted files, attempting manual decryption, or using third-party recovery software or antivirus tools, as these actions may result in permanent data loss.

Itqw Ransomware is a malicious software that belongs to the STOP/Djvu ransomware family. It targets various types of files, such as videos, photos, documents, and more, encrypting them and rendering them inaccessible. Itqw ransomware encrypts files using a strong encryption algorithm and a unique key. The ransomware appends a distinct .itqw extension to each encrypted file and demands a ransom payment, typically in the form of Bitcoin cryptocurrency, to supposedly unlock the files. The ransom amount can vary depending on the specific variant of the Itqw Ransomware. Itqw Ransomware creates a ransom note, a file named _readme.txt, which contains instructions on how to contact the attackers and pay the ransom. The ransom amount ranges from $490 to $980 in Bitcoin.

Ithh Ransomware is a variant of the Djvu ransomware family that encrypts files on the victim's computer and appends the .ithh extension to the filenames. For example, it changes 1.jpg to 1.jpg.ithh and 2.png to 2.png.ithh. After encrypting the files, Ithh Ransomware generates a ransom note within a file named _readme.txt. The attackers demand a ransom payment, usually in cryptocurrency, to provide the decryption key to restore access to the encrypted files. However, paying the ransom is strongly discouraged, as there is no guarantee that the attackers will provide the decryption tools. The Ithh ransom note is a message left by the Ithh Ransomware attackers after encrypting the victim's files. The note typically contains information about the ransomware attack, instructions on how to pay the ransom ($490 or $980 in cryptocurrency).

Itrz Ransomware is a malicious software that belongs to the STOP/DJVU family of ransomware. It is designed to encrypt files on a victim's computer, making them inaccessible until a ransom is paid to the cybercriminals. The ransomware appends the .itrz extension to the filenames of encrypted files, rendering them unusable without the decryption key. Itrz ransomware is associated with the Djvu ransomware family and may be distributed alongside information-stealing malware like RedLine or Vidar. Itrz ransomware encrypts a wide range of common file types, including documents, images, videos, and more. After encrypting the files, Itrz ransomware generates a ransom note, usually located within a file named _readme.txt. The note informs the victim that their files have been encrypted and demands a ransom payment, typically ranging from $490 to $980 in Bitcoin, in exchange for the decryption key.

Ptrz Ransomware is a file-encrypting ransomware infection that restricts access to data such as documents, images, and videos by encrypting files with the .ptrz extension. The ransomware operates by using the Salsa20 encryption algorithms to scramble the contents of the targeted files. Once the files are encrypted, they cannot be opened by any programs. Once the PTRZ Ransomware infects a computer, it targets various types of files and encrypts them. Due to the strong encryption method used, it becomes incredibly hard, if even possible, to pick the decryption key without cooperating with the attackers. After the encryption process, PTRZ Ransomware displays a ransom note in a _readme.txt file. This note contains instructions on how to contact the authors of the ransomware and the ransom amount, which ranges from $490 to $980 (in Bitcoins). The victims are asked to contact the malware developers via the support@freshmail.top and datarestorehelp@airmail.cc email addresses.

Xollam is a high-risk file-encrypting malware, a variant of the Mallox Ransomware, which is part of the TargetCompany Ransomware family. It is designed to lock all the files on an infected PC, rendering them inaccessible. The ransomware encrypts the victim's files using the ChaCha20 encryption algorithm and generates the encryption keys using a combination of Curve25519, an example of elliptic curve cryptography. Xollam Ransomware appends the .xollam extension to the end of the encrypted data filename. Other file extensions observed were: .FARGO3, .exploit, .avast, .bitenc, in addition to the use of victims' names as the extension. Xollam creates a ransom note named FILE RECOVERY.txt. The ransom note states that files encrypted by Xollam ransomware cannot be used until they are decrypted with a tool purchased from threat actors behind the attack. Attempts to modify files or restore them using third-party tools will damage them.

Pthh Ransomware is a file-encrypting malware that restricts access to data such as documents, images, and videos by encrypting files with the .pthh extension. It belongs to the STOP/DJVU ransomware family. The primary goal of this ransomware is to extort money from victims by demanding a ransom in exchange for the decryption key. The ransomware uses the Salsa20 encryption algorithm. If Pthh cannot establish a connection to the server before starting the encryption process, it uses an offline key, which is the same for all victims, making it possible to decrypt .pthh files in the future. After the encryption process, Pthh ransomware displays a ransom note in a _readme.txt file. The note contains instructions on how to contact the authors of this ransomware and the ransom amount, which ranges from $490 to $980 (in Bitcoins). The victims are asked to contact the malware developers via the support@freshmail.top and datarestorehelp@airmail.cc email addresses.

Grounding Conductor is a type of malware known as ransomware. Its primary purpose is to prevent victims from accessing their files by encrypting them. This ransomware variant is also known as a Crypto Virus or Files locker due to its encryption capabilities. Grounding Conductor ransomware adds a specific extension to the files it encrypts. The file renaming pattern is [original_filename].{victim's_ID}.Grounding Conductor.zip. For example, a file originally named photo.jpg might be renamed to photo.{12345678-1234-1234-1234-123456789012}.Grounding Conductor.zip. Grounding Conductor ransomware uses a specific encryption method to lock the files of its victims. The encrypted files include a file marker at the end of each encrypted file: &XChaCha20 or XChaCha20. After encrypting the files, Grounding Conductor ransomware leaves a ransom note named readme.txt. This note typically contains instructions for the victims on how to pay the ransom to get their files decrypted.
