Ransomware

Solution Ransomware is a menacing type of malware that belongs to the MedusaLocker ransomware group, known for encrypting files and demanding ransoms for decryptions. Once it infiltrates a system, this ransomware targets valuable data and appends a unique file extension to the filenames—specifically, .solution352. For example, a file that was previously document.docx would be renamed to document.docx.solution352 after encryption. The ransomware employs a combination of RSA and AES encryption algorithms to lock the files, making it nearly impossible to open them without the decryption key. Post-encryption, a ransom note titled How_to_back_files.html is generated and placed within every affected directory. This document instructs victims to contact the attackers within a specified timeframe, typically 72 hours, to negotiate a ransom. The attackers use this tactic as leverage, threatening to increase the ransom or begin leaking stolen data if the victim fails to comply promptly.

Discovered as part of the MedusaLocker ransomware family, DavidHasselhoff Ransomware is a malicious software that encrypts data and demands a ransom for decrypting it. This ransomware appends files with unique extensions such as .352_davidhasselhoff, indicating a yet unidentified variant. Designed to lock files using the robust RSA and AES cryptographic algorithms, the ransomware leaves victims unable to access their data without a private key held by the attackers. Once files are encrypted, a ransom note titled How_to_back_files.html is created on the infected device, directing victims to contact the attackers to negotiate the ransom payment. The ransomware's ransom note warns victims that any attempt to restore files with third-party software could result in permanent data corruption, urging them to avoid such actions.

Evidence Of Child Pornography Ransomware represents a particularly malicious form of malware that encrypts a victim's files and demands a ransom for their release. Making matters worse, this ransomware accuses victims of possessing illegal content to intimidate them further. Upon infection, it encrypts files and appends random extensions to their names, such as .d3prU, complicating any immediate identification or recovery efforts. The ransomware usually targets various file types, including images, documents, and videos, using strong encryption algorithms, typically AES or RSA, rendering the files inaccessible without the decryption key. Victims encounter a ransom note crafted to increase panic and pressure, warning them about consequences and demanding payment. The note is delivered in two formats: READ ME !.txt and an HTML file named after the user, such as [username]_GUI.html, typically placed in folders containing encrypted files and on the desktop. Sadly, as of now, there are no publicly available decryption tools capable of unlocking files affected by this ransomware, as the encryption is implemented securely.

Moon Ransomware is a sophisticated strain of malicious software that targets computer systems to encrypt user data, rendering it inaccessible. This ransomware specifically appends a unique identifier followed by the .moon extension to affected files, thus complicating attempts to open or use these files without the proper decryption keys. For example, a file named document.docx could be altered to document.docx.{unique_identifier}.moon. This pattern disrupts the file structure, making it clear when files have been compromised. The encryption method employed by Moon Ransomware is highly secure, often based on strong cryptographic algorithms that are nearly impossible to break without specific keys held by the attackers. Once encryption is completed, the ransomware generates a ransom note titled README.txt and typically places it in directories where encrypted files reside, as well as on the desktop for high visibility. This note explains the ransom demand, the method of payment (usually in cryptocurrency like Bitcoin), and provides contact information for the attackers while discouraging victims from using third-party decryption tools by threatening permanent data loss or increased ransom fees.

Discovered in 2024, King Ransomware is a notorious ransomware variant stemming from the Proton family, designed to encrypt files on infected systems. Once it infiltrates a computer, it appends the .king file extension to encrypted files along with an email address, effectively rendering them inaccessible. For instance, a file named document.docx would be transformed into document.docx.[king_ransom1@mailfence.com].king. This ransomware uses sophisticated encryption algorithms, making file recovery challenging without specific decryption keys. An ominous ransom note named #Read-for-recovery.txt is created on the infected system and also changes the desktop wallpaper to instruct victims on how to reclaim their files. The note directs victims to contact the cybercriminals through the provided email addresses and await further instructions.

DennisTheHitman Ransomware is a malicious program that falls under the notorious GlobeImposter ransomware family. It compromises victim systems by encrypting valuable data and demands a ransom for their decryption. The infection typically appends filenames with the extension .247_dennisthehitman, transforming a file named example.jpg to example.jpg.247_dennisthehitman. This extension may vary based on the specific variant of the ransomware. Once the encryption process is complete, the ransomware creates a ransom note in an HTML file titled how_to_back_files.html. This note informs the victim that their company network has been infiltrated, data has been encrypted using RSA and AES cryptographic algorithms, and sensitive information has been stolen and stored on a private server. The note deters victims from renaming or modifying the encrypted files and warns against using third-party recovery tools, which it claims will permanently corrupt the files.

Defi Ransomware represents a significant threat in the realm of cybersecurity. This particular ransomware, part of the Makop family, operates by encrypting the victim's files and appending a distinctive extension to their names. For instance, original filenames are modified by adding a unique ID, the attackers' email address, and a .defi[random] extension, making the files inaccessible. On our test system, a file named photo.jpg was transformed into photo.jpg.[random-ID].[wewillrestoreyou@cyberfear.com].defi1328. Post encryption, the ransomware drops a ransom note in a text file named +README-WARNING+.txt, which typically appears on the desktop. The cybercriminals behind Defi ransomware request a ransom payment for the decryption key, promising to provide the decryption tool and warning against using third-party software, which they claim could result in permanent data loss.

The Bully Ransomware is a severe malware strain identified by cybersecurity researchers. This ransomware is rooted in the Chaos ransomware variant, and its primary objective is to encrypt files on the victim's computer and demand a ransom for their decryption. Once inside a system, The Bully Ransomware modifies filenames by appending the .HAHAHAIAMABULLY extension—changing, for example, document.docx to document.docx.HAHAHAIAMABULLY. The ransomware also generates a ransom note named read_it.txt, which typically appears on the desktop or in directories containing encrypted files. This note informs victims that their data has been encrypted and stolen, while warning against using third-party decryption tools under the threat of permanent data loss.
