Viruses

Messec Ransomware is a type of virus, a malicious software that encrypts files on a victim's computer, rendering them inaccessible. The primary goal of Messec, like other ransomware, is to demand a ransom from the victim in exchange for the decryption of the affected files. Once Messec infects a computer, it encrypts the files and appends the .messec extension to each filename. For example, a file originally named 1.jpg would be renamed to 1.jpg.messec. The specific encryption algorithm used by Messec ransomware is not explicitly mentioned in the search results. However, ransomware typically uses strong encryption algorithms, such as AES (Advanced Encryption Standard) or RSA (Rivest-Shamir-Adleman), to encrypt files. Messec creates a ransom note named READ_ME.txt in every directory containing encrypted files. The note informs the victim that their files have been encrypted and provides instructions on how to pay the ransom to recover the files. The attackers offer to decrypt three files for free as proof of their decryption capability. The ransom amount is $100, with an additional $25 for each subsequent hour.

Jawr is a type of ransomware that belongs to the Djvu ransomware family. It is a malicious software that encrypts files on a victim's computer, rendering them inaccessible. The ransomware then demands a ransom from the victim, typically in Bitcoin, to decrypt the files. Once Jawr ransomware infects a system, it targets various types of files, such as videos, photos, and documents. It modifies the file structure and adds the .jawr extension to each file, making them inaccessible and unusable without the decryption key. Jawr ransomware uses the Salsa20 encryption algorithm to encrypt the files. This is a robust ciphering method, making it extremely difficult, if not impossible, to pick the decryption key without cooperating with the attackers. After encrypting the files, Jawr ransomware leaves a ransom note named _readme.txt on the system. This note informs the victim that their files have been encrypted and provides instructions on how to pay the ransom to get the decryption key. The ransom note often includes threats of permanent data loss or increased ransom amounts if the ransom is not paid within a specified timeframe.

MuskOff Ransomware is a malicious program based on the Chaos Ransomware, which encrypts files on the victim's computer and demands payment for their decryption. It was discovered by researchers during a routine inspection of new malware submissions to the VirusTotal platform. MuskOff Ransomware appends the .MuskOff extension to the filenames of encrypted files. For example, a file originally named 1.jpg would appear as 1.jpg.MuskOff after encryption. Ransomware generally uses strong encryption algorithms, such as AES or RSA, to encrypt files. After encrypting files, MuskOff Ransomware creates a ransom note named read_it.txt. The note states that the victim's files have been encrypted and demands payment in Bitcoin for their decryption. The cybercriminals request 1500 USD in BTC, but the amount listed in BTC (0.1473766) is worth over 5000 USD at the time of writing.

Gyew Ransomware is a variant associated with the Djvu malware family. It operates by encrypting files, appending the .gyew extension to their names, and leaving behind a ransom note named _readme.txt. For example, it changes 1.jpg to 1.jpg.gyew, 2.png to 2.png.gyew, and so on. The ransom note claims that numerous files, including images, databases, and important documents, have been encrypted. This renders the files inaccessible without the decryption key. The ransomware targets common files like Office documents, drawings, photos, images, videos, and so on. The ransom note is typically left on the desktop. It instructs victims to acquire a decryption tool and a unique key to regain access to their files. The initial ransom demand is set at $980, but it's halved to $490 if paid within 72 hours.

Blackoutware is a type of ransomware, a malicious software designed to encrypt data and demand ransoms for its decryption. This article will provide a comprehensive understanding of Blackoutware Ransomware, its infection methods, the file extensions it adds, the encryption it uses, the ransom note it creates, and the potential decryption tools available. Blackoutware Ransomware is a crypto virus that encrypts files on a victim's computer and appends their filenames with a .blo extension. For instance, a file initially titled 1.jpg would appear as 1.jpg.blo. After the encryption process, a ransom note titled !!!WARNING!!!.txt is dropped into the C:\Users[username] folder. The ransom note states that the victim's files have been encrypted and that decryption requires payment. The ransom is typically demanded in cryptocurrencies, such as Litecoin (LTC) or Bitcoin (BTC), with the amount often listed as 5000 euros. The victim is usually given 72 hours to comply, and the note warns against modifying the encrypted files or using third-party decryption tools, as this could result in permanent data loss.

Gyza Ransomware is a malicious software that belongs to the STOP/Djvu ransomware family. It targets various file types, encrypts them, and appends the .gyza extension to the encrypted files, rendering them inaccessible. After encryption, Gyza delivers a ransom note (_readme.txt) instructing victims to pay a ransom to obtain a decryption tool and a unique key to restore access to their files. The ransomware uses the Salsa20 encryption algorithm to encrypt files. The ransom note instructs victims to contact the cybercriminals via support@freshmail.top or datarestorehelp@airmail.cc email addresses. The ransom amount ranges from $490 to $980, payable in Bitcoin.

Gycc is a strain of ransomware that is linked to the Djvu malware family. This malicious software is designed to encrypt files on a victim's computer, rendering them inaccessible. The encrypted files are appended with the .gycc extension. For instance, a file originally named 1.jpg would be renamed to 1.jpg.gycc. Ransomware typically uses strong encryption algorithms, such as RSA or AES, to lock victims' files. Once encrypted, the files can only be unlocked by a decryption key known only to the attacker. After encrypting the files, Gycc ransomware leaves a ransom note named _readme.txt. This note informs the victim that their files have been encrypted and provides instructions on how to contact the attackers. The victims are usually asked to contact the malware developers via specific email addresses. The ransom demanded can range from $490 to $980, typically in Bitcoin cryptocurrency.

Danger Siker Ransomware is a type of malware that encrypts files on a victim's computer, making them inaccessible. It appends the .DangerSiker extension to filenames (e.g., 1.jpg becomes 1.jpg.DangerSiker). The ransomware changes the desktop wallpaper and creates a ransom note named mesajin_var_amcik.txt in Turkish, demanding a payment of 0.5 XMR (Monero cryptocurrency) for file decryption. The ransom note instructs the victim not to attempt file recovery independently, as it could worsen the situation. Once the payment is made, the victim is directed to send an email to mesaezzoris@gmail.com. Below is a sample of the ransom-demanding message.
