Ransomware

Bbq Ransomware is a destructive malware strain categorized under the Makop ransomware family, widely recognized for its aggressive data encryption and extortion tactics. Once it infiltrates a victim’s system, it identifies valuable files and encrypts them using robust cryptographic algorithms designed to be virtually unbreakable without the attackers’ cooperation; Makop variants like Bbq typically use a mix of symmetric and asymmetric encryption, making brute-forcing or key guessing ineffective. During this process, .bbq46 is appended to each encrypted file, following a unique pattern: the original filename is suffixed with the victim’s unique ID, the attacker’s email for "customer support", and the new file extension. Files that once ended in common extensions like .docx or .jpg will instead appear as filename.jpg.[victimID].[dashboard487@onionmail.org].bbq46. To further signal the infection, +README-WARNING+.txt ransom note is dropped into most affected directories and displayed on the desktop. The note warns victims not to use third-party decryption tools or antivirus software, threatens permanent data loss, and promises file recovery upon payment. Bbq Ransomware also changes the desktop wallpaper with an extortion message detailing the infection and pointing to the ransomware operator’s contact addresses.

LegionRoot Ransomware stands out as a recently discovered crypto-malware that specifically targets user files to extort payment from its victims. After stealthily infiltrating a system—often via phishing emails, malicious attachments, or compromised downloads—it initiates an encryption process using the RSA encryption algorithm. Notably, each targeted file's name is appended with a string of random characters, such as 1.jpg.ZQJWWm&X&W, rather than a static extension, making it harder for users and automated tools to instantly recognize the infection. Once LegionRoot_ReadMe.txt is generated, typically placed in every affected folder, victims realize their files are inaccessible; documents, photos, databases, and other crucial data become unreadable, and attempts to open them are futile. The ransom note within this text file demands $500 worth of Bitcoin sent to a specified wallet, promising a private decryption key in return. Cyber criminals behind LegionRoot claim that file recovery is impossible without their unique private key, offering to demonstrate their ability by decrypting a single file if contacted.

Bert Ransomware is a strain of malicious software designed to encrypt files on a victim's computer, rendering them inaccessible without a decryption key. This type of ransomware appends the file extension .encryptedbybert to each of the affected files, altering their original filenames into a unique encrypted format. The encryption process employed by Bert is typically quite robust, often using advanced algorithms that make decryption without the proper key virtually impossible. Upon encrypting the files, Bert leaves a ransom note, titled .note.txt, in each directory containing encrypted files. This note serves as a communication tool from the attackers, detailing the compromised nature of the victim's files and providing instructions for contacting the cybercriminals with the intent of obtaining the decryption key. The attackers often exhort victims to reach out via specified communication methods, emphasizing that payment is necessary to recover access to their data.

Mammon Ransomware is a type of malicious software categorized under the ransomware family, which works by encrypting the victim's files and subsequently demanding a ransom for file decryption. This ransomware is notorious for appending its encrypted files with extensions, specifically ending in .aaabbbccc. Victims will notice their files transformed as original names are suffixed with the attackers' email, a unique ID, and the said extension. For instance, a file named 1.jpg could appear as 1.jpg.email-[example@gmail.com]id-[XXXXX].aaabbbccc post-infection. Utilizing powerful encryption algorithms, typically either symmetric or asymmetric cryptography, this ransomware makes decryption challenging without access to the unique key generated during encryption. Upon infiltration, howtoDecrypt.txt - a ransom note - materializes in the system, informing the victims of their locked files. The note usually appears in the directories containing encrypted files, providing instructions on how to pay the ransom and contact the cybercriminals via email or Telegram for decryption.

CRFILE Ransomware is a malicious software belonging to the MedusaLocker family designed to encrypt files on a victim’s computer and demand a ransom for their decryption. Once the ransomware infects a system, it appends a distinctive .CRFILE2 extension to the encrypted files, effectively locking them from access. The encryption process employs a combination of RSA and AES algorithms, which are well-known for their complexity and efficiency in securing data against unauthorized decryption. Upon successful encryption, CRFILE Ransomware generates a ransom note, typically titled READ_NOTE.html, which is placed in accessible directories on the compromised system. This note warns victims against attempting third-party recovery solutions and insists that only the attackers possess the decryption keys necessary to unlock the files.

Se7en Ransomware is a malicious program identified as part of the Babuk ransomware family, which gains access to targets through various deceptive tactics, including infected email attachments, pirated software, and malicious advertisements. Once inside a system, it begins the encryption process by converting files into inaccessible formats, thereby disrupting typical data access. The files affected by this ransomware are marked with a .se7en extension, transforming filenames such as 1.jpg into 1.jpg.se7en, making it clear which data has been compromised. This encryption method renders the files unusable without the correct decryption key, which attackers claim to possess. Upon completing the encryption, the ransomware generates a How To Restore Your Files.txt ransom note on compromised devices, usually placed in visible directories to ensure victims notice it quickly. This note serves not only as a warning but also as a set of instructions, asserting that encryption can only be undone by securing a decryption tool from the attackers, often involving a financial transaction conducted through anonymous platforms such as Bitcoin.

Numec Ransomware is a malicious software designed to encrypt the files on a victim's computer system, effectively locking them out of their own data. It appends the .numec extension to the filenames of encrypted files, turning a previously accessible document into an unusable format that requires decryption to be opened again. This ransomware employs sophisticated encryption algorithms that make it nearly impossible to decrypt the files without the specific decryption key that the attackers possess. When files are encrypted, they are typically stored in a folder named "EncryptedFiles" on the victim's desktop. Furthermore, a ransom note, which is found under the filename GetFilesBack.txt, is dropped on the system, providing instructions on how to potentially regain access to the locked files. Unfortunately, decrypting these files is a challenge; no publicly available decryption tool can handle this particular ransomware variant. Victims are therefore faced with the dilemma of relying on potentially unsafe methods to recover their files.

Crone Ransomware is a malicious program that encrypts files on infected computers, rendering them inaccessible to users. After encrypting the files, it appends the .crone extension to their original names, making them easily identifiable as encrypted. For instance, a file named document.pdf would become document.pdf.crone. This ransomware employs robust cryptographic algorithms, making file recovery without the attackers' assistance nearly impossible. Once the encryption process is complete, the ransomware drops a ransom note titled How To Restore Your Files.txt. The note is typically found in various folders containing encrypted files and provides instructions, often in both English and Russian, on how to pay the ransom to obtain a decryption tool. Victims are usually demanded to pay in Bitcoin to a specified wallet address, highlighting the anonymous nature of these transactions. It's important to note that paying the ransom does not guarantee file recovery, as many cybercriminals do not deliver the promised decryption tool.
