Ransomware

Moscovium Ransomware is a highly damaging type of malware that operates by encrypting data and demanding a ransom in exchange for the decryption key. This devious program appends a unique extension, .m0sC0v1um, to the encrypted files, making them inaccessible to users without the proper key. Typically, a file that was once named document.docx would be altered to document.docx.m0sC0v1um, signifying the encryption. The ransomware uses advanced cryptographic algorithms to secure the files, albeit the specifics of which algorithm are employed, whether symmetric or asymmetric, are not immediately disclosed by the attackers. After encrypting the victim's data, Moscovium leaves a ransom note in the form of a text file named !!!_DECRYPT_INSTRUCTIONS_!!!.txt on the desktop, providing the unfortunate user with instructions for recovery.

Mamona Ransomware is a severe type of malicious software designed to encrypt a victim's files and demand payment for their decryption. This cyber threat specifically appends the .HAes extension to each affected file, transforming them into unusable and inaccessible versions of their former selves. Users encountering this ransomware might notice files like image.jpg turned into image.jpg.HAes, indicating a successful attack. Encryption is achieved using robust cryptographic algorithms that render it nearly impossible for victims to access their data without the decryption key held by the attackers. Upon completion of the encryption process, victims find their desktop wallpaper changed, coupled with a text file labeled README.HAes.txt as the ransom note. This note is a grim reminder of the attackers' demands, warning against seeking external help or contacting law enforcement, and usually providing a pathway to communicate with the criminals for instructions on payment.

Data Ransomware is a dangerous encryption malware discovered during routine analysis of malware samples uploaded to VirusTotal. It belongs to the Proton ransomware family and is designed to encrypt files on an infected computer. Victims will notice that their files are inaccessible and appended with an email address and a distinctive extension, .data3, indicating they have been encrypted. This ransomware changes the desktop wallpaper and creates a ransom note named #Read-for-recovery.txt, instructing victims to contact the attackers via an email address provided within. The presence of this ransomware renders files unusable unless a specific decryption key is applied, which is held by the cybercriminals behind the attack. Unfortunately, paying the ransom does not guarantee file recovery, as attackers may not provide the decryption tools after payment.

SuperBlack Ransomware, identified as a notable threat in the cybersecurity landscape, is a ransomware-type program developed to encrypt data and demand ransom payments from victims in exchange for decryption keys. Typically associated with the LockBit ransomware family, SuperBlack Ransomware uses asymmetric cryptographic algorithms to render files inaccessible. Once it infiltrates a system, this malware appends encrypted files with a unique and random character string as an extension, transforming a file named document.jpg into something like document.jpg.hN7fLm29a. In addition to file encryption, the ransomware alters the desktop wallpaper and generates a ransom note named [random_string].README.txt. This note, strategically placed in various system locations, aggressively informs victims of their encrypted data and demands monetary payment to prevent data leakage and file loss. The note also warns against attempting any self-recovery or modification of the encrypted data, claiming it would result in permanent data loss.

Anubi Ransomware is a malicious software that encrypts files on an infected computer, demanding a ransom payment from victims to restore access to their data. Like many ransomware variants, it operates by appending a new extension, in this case, .Anubi, to the filenames of encrypted files, making them inaccessible without a decryption tool. Typically, this ransomware uses advanced encryption algorithms, which can be difficult to break without the decryptor provided by the attackers. Anubi further ingrains itself into a victim's system by changing desktop wallpapers and displaying a pre-login screen message indicating that files are both stolen and encrypted, guiding victims to seek recovery instructions. A crucial component of its strategy is the creation of a ransom note named Anubi_Help.txt, which is deposited in multiple folders on the system. This note contains email addresses for contact with the attackers and explicit instructions for ransom payment, often accompanied by threats against tampering with the encrypted files or seeking third-party assistance.

VanHelsing Ransomware is a malicious software belonging to the ransomware category, notorious for encrypting victim’s files and demanding a ransom in the form of Bitcoin for their decryption. This type of ransomware strategically applies a distinct .vanhelsing extension to each encrypted file, effectively transforming a file originally named example.jpg into example.jpg.vanhelsing. Employing sophisticated cryptographic algorithms, VanHelsing ransomware ensures that decryption without the key held by the attackers is virtually impossible. Once the files' encryption is complete, it changes the desktop wallpaper and creates a ransom note named README.txt, which is typically left in an accessible location for the user, such as the desktop. This note informs victims that their data has been compromised and instructs them on how to proceed with the ransom payment while threatening to leak stolen data if demands are not met.

GKICKG Ransomware is a malicious software that encrypts files on infected systems, rendering them inaccessible without a decryption key that the attackers offer for a ransom. Known for its severe impact, this ransomware primarily targets corporate networks, encrypting files and appending a distinctive extension to them. Victims will find their files renamed with a format that integrates their victim ID, ending with the .GKICKG extension. For instance, a file that was once named document.docx would become document.docx.{Victim_ID}.GKICKG. The ransomware employs robust encryption algorithms, often making it nearly impossible to decrypt the files without the attacker's private decryption key. Upon encryption, the ransomware generates a ransom note in a text file named README.TXT, usually placed in every directory where files have been encrypted. This note outlines the attack details, the ransom demands, and threats about leaking stolen data if payment is not made.

Zsszyy Ransomware is a malicious software designed to encrypt files on an infected system, ultimately coercing the victim into paying a ransom for decryption. This ransomware is part of a family of similar threats, sharing traits with others such as Tianrui and Hush. Once it infiltrates a computer, it targets a wide array of file types, rendering them inaccessible by appending a unique extension, .zsszyy, to filenames. For instance, files that were once named document.docx become document.docx.{unique-ID}.zsszyy. The encryption encryption algorithms employed by Zsszyy are typically strong and sophisticated, ensuring that affected files cannot be easily deciphered without a specific decryption key, which is held by the cybercriminals operating the ransomware. This further complicates efforts to recover files without resorting to paying the demanded fee. Victims encounter a ransom note, entitled README.TXT, placed strategically within affected directories. This note delivers the attackers’ demands and threats, often warning against using third-party recovery services and promising that file decryption is swift post-payment.
