Ransomware

Pomochit Ransomware is a malicious software variant that falls under the ransomware category, specifically known for encrypting files on infected systems with the intent to extort money from victims. Primarily targeting organizational networks, Pomochit is identified as part of the MedusaLocker ransomware family. Once this ransomware infiltrates a system, it employs a robust encryption process, rendering files inaccessible to users. Encrypted files will have the extension .pomochit01 appended to their names, such as a document named report.docx becoming report.docx.pomochit01. The encryption technology utilized is sophisticated, employing both RSA and AES algorithms, known for their secured methods of encryption targeting sensitive data. As a result, regaining access to the compromised files is exceedingly challenging without the decryption keys held by the ransomware operators. After the encryption is completed, Pomochit generates a ransom note named How_to_back_files.html, which is dropped onto the victim's system, often on the desktop or in folders containing encrypted files. This ransom note outlines the extent of the attack, warning victims against attempting to recover their files using third-party tools, as such actions are claimed to irreversibly damage the data.

OceanSpy Ransomware is a highly malicious strain of ransomware built on the Chaos encryption framework. This variant is designed to target user files by encrypting them and appending a unique extension comprising four random characters, rendering the files inaccessible. Victims searching for their previously functional documents may notice that file names, such as report.docx, suddenly turn into report.docx.9abc. Once the encryption is complete, the ransomware replaces the desktop wallpaper with a disturbing message while generating a ransom note labeled OceanCorp.txt on the victim's device. This note informs the users that their files are encrypted and provides instructions for obtaining a decryption key, which involves making a payment in Bitcoin. Individuals are encouraged to contact the attackers via Telegram, further emphasizing the risks posed by this ransomware variant.

ZILLA Ransomware belongs to the notorious Dharma family of ransomware, a breed known for its significant impact and high rate of infection. Upon infiltrating a system, ZILLA Ransomware encrypts files and changes their names by appending the victim's ID, a contact email address (filezilla@cock.li), and the .ZILLA extension. For instance, a file named example.png would be renamed to example.png.id-[victim-ID].[filezilla@cock.li].ZILLA. This ransomware employs advanced encryption algorithms, making it virtually impossible to decrypt files without the correct decryption key, which is kept securely by the attackers. It modifies system settings to ensure persistence and can even disable firewalls and delete Volume Shadow Copies to prevent restoration of files through conventional means. Victims of ZILLA Ransomware are greeted with a ransom note both as a pop-up window and as a text file titled ZILLA-INFO.txt.

NetForceZ Ransomware is a severe type of malware that targets computer systems with the intent to encrypt files, rendering them inaccessible without a specific decryption key. It commonly infiltrates systems through security vulnerabilities, or via social engineering tactics like phishing emails which trick users into unwittingly downloading and executing the ransomware. Upon successful infection, NetForceZ Ransomware scans the system for files to encrypt, changing their extensions to .NetForceZ, something easily identifiable, often unique to the malware. Its encryption algorithm is typically robust and military-grade, making file recovery exceedingly difficult without the correct decryption key. The rationale behind this approach is to force victims into paying a ransom, usually in cryptocurrency, in exchange for the decryption key necessary to restore those files. As part of its malicious activities, the malware leaves a ransom note in the form of a text file named ReadMe.txt in various affected directories, detailing instructions on how victims can presumably recover their compromised files by paying the demanded ransom.

RADAR Ransomware represents a particularly insidious strain of malware that compromises systems by encrypting files and demanding ransom payments for their decryption. This ransomware operates by appending random character strings to the names of affected files, making it difficult for victims to identify or use their data. usually it's 8-character alphanumerical sequence, something like .Qe7l01NP or similar. After encryption, it generates a ransom note titled README_FOR_DECRYPT.txt, usually found in every folder containing encrypted files. The message warns victims against tampering with or deleting the locked files, as these actions could render decryption impossible. Unfortunately, there is no guarantee that paying the ransom will lead to the safe recovery of files, as attackers often fail to provide the necessary decryption tools even after receiving payment.

LostInfo Ransomware is a malicious software designed to encrypt the files on a victim's computer, making them inaccessible and effectively holding them hostage until a ransom is paid. This type of ransomware typically targets a wide range of file types, ensuring that critical data such as documents, photos, and databases are all affected. Primarily, it appends the .lostinfo extension to each encrypted file, signifying that the file has been compromised. The encryption utilized by LostInfo Ransomware generally employs strong algorithms, such as AES (Advanced Encryption Standard) or RSA (Rivest–Shamir–Adleman), which are virtually impossible to decrypt without the corresponding key. The attacker leaves behind a ransom note, typically named README.TXT, in each affected directory, which contains instructions on how to pay the ransom, usually demanding payment in cryptocurrency like Bitcoin to maintain anonymity.

GameCrypt Ransomware is a malicious software designed to encrypt files on an infected computer, demanding a ransom payment for their decryption. Upon infection, it appends the file extension .GameCrypt to all encrypted files, making them unusable until a victim complies with the ransom demands. This ransomware employs a sophisticated encryption algorithm to secure the files, typically utilizing AES, which renders the data inaccessible without the proper decryption key. Victims are often greeted with a ransom note titled how_to_back_files.hta, which is usually placed on the desktop or within the affected folders, instructing them on how to pay the ransom, often in cryptocurrency, to purportedly regain access to their files.

NullBulge Ransomware represents a formidable new threat in the ever-evolving landscape of cybercrime, specifically targeting AI and gaming communities. Originating from the notorious LockBit family, this ransomware variant not only encrypts files but also appends a unique, random extension such as .uhei662ns to the filenames. Victims might see their files transformed from document.docx to document.docx.uhei662ns, making them inaccessible without the decryption key. NullBulge ransomware is known to employ robust encryption algorithms, typically AES-256, which ensures that the files remain locked until the ransom is paid. Additionally, the ransomware modifies the victim's desktop wallpaper to inform them of the breach and drops a ransom note, titled [extension].README.txt, in every affected directory. This note provides instructions on how to contact the cybercriminals, including links to TOR websites for secure communication and a personal decryption ID.
