Ransomware

Qepi Ransomware is a malicious software that belongs to the STOP/DJVU family of ransomware, known for its file encryption and extortion tactics. This ransomware variant specifically targets personal and professional data stored on infected computers, encrypting files and demanding a ransom for their decryption. Upon infection, Qepi Ransomware scans the computer for files and encrypts them, appending a specific extension, .qepi, to the filenames. This marks the files as encrypted and inaccessible without the decryption key. The ransomware uses a combination of AES and RSA encryption algorithms, making the decryption without the corresponding keys virtually impossible. After encrypting the files, Qepi Ransomware generates a ransom note named _readme.txt, which is typically placed on the desktop and in folders containing encrypted files. This note contains instructions for the victim on how to contact the cybercriminals and pay the ransom to potentially receive a decryption key.

Tuborg Ransomware is a malicious software variant that encrypts files on the infected systems, rendering them inaccessible to users. It is identified as a variant of the Proton ransomware family. This ransomware specifically targets various file types and appends a unique extension, .tuborg, to the filenames after encrypting them. For example, a file originally named 1.jpg would be renamed to 1.jpg.[Hiit9890@cyberfear.com].tuborg after encryption. Upon successful infection, Tuborg Ransomware employs robust encryption algorithms, specifically AES (Advanced Encryption Standard) and ECC (Elliptic Curve Cryptography), to lock files. This encryption is highly secure, making unauthorized decryption extremely challenging without the necessary decryption keys held by the attackers. The ransomware generates a ransom note in a text file named #tuborg-Help.txt, which is placed on the desktop or in folders containing encrypted files. This note informs victims that their files have been encrypted and stolen, and recovery without the attackers' decryption service is impossible. It demands payment in exchange for decryption software and the destruction of the stolen data. The note also typically includes contact information and warns against seeking help from third-party recovery companies, suggesting that quick action may reduce the ransom amount.

Robaj Ransomware is a type of malicious software that belongs to the Conti ransomware family. This ransomware encrypts all the data on a victim's computer, including photos, text files, excel tables, audio files, videos, and more, rendering them inaccessible without a decryption key. Once Robaj ransomware infects a computer, it appends a specific extension to the filenames of the encrypted files. This extension is .Robaj. For example, a file originally named photo.jpg would be renamed to photo.jpg.Robaj, and similarly, document.docx would become document.docx.Robaj. Robaj ransomware uses strong encryption algorithms to lock the files on the infected computers. The exact type of encryption—whether symmetric or asymmetric—is not specified in the sources, but given its association with the Conti family, it likely employs robust mechanisms to prevent unauthorized decryption. The ransomware drops a ransom note named readme.txt on the victim's computer. This note informs the victim that their files have been encrypted and that they must pay a ransom in Bitcoin to recover their data. Interestingly, the ransom note does not specify the amount to be paid; it merely instructs the victim to contact the attackers via anonymous communication channels, which are not clearly defined in the note.

ATCK Ransomware is a malicious software variant that encrypts files on infected computers, rendering them inaccessible to users. This ransomware is part of the Dharma family, known for its damaging capabilities and widespread impact. This article provides an in-depth look at how ATCK ransomware operates, including its infection methods, encryption process, ransom note details, and potential recovery options. Upon infection, ATCK ransomware encrypts files and modifies their filenames significantly. It appends the victim's unique ID, the attacker's email address, and the .ATCK extension to each encrypted file's name. For instance, a file named example.jpg would be renamed to example.jpg.id-{random-ID}.[attackattack@tutamail.com].ATCK after encryption. This renaming scheme not only signifies the file has been encrypted but also provides the victim with contact information for the ransom negotiation. ATCK ransomware delivers its ransom demands through two primary methods: a text file named info.txt and a pop-up window. Both notes inform the victim that their files have been encrypted and offer a way to restore them through contact with the attackers via provided email addresses (attackattack@tutamail.com or attackattack@cock.li). The ransom notes emphasize that attempting to decrypt files with third-party software could lead to permanent data loss, and they offer free decryption of a few files as proof that they can reverse the encryption.

IRIS Ransomware is a malicious software that encrypts files on a victim's computer, demanding a ransom for their decryption. It is identified as a variant of the Chaos ransomware family. This crypto-virus is particularly harmful as it not only locks files but also threatens to leak stolen sensitive data if the ransom is not paid. Upon infection, IRIS Ransomware begins encrypting files across various formats, including documents, images, and databases. It appends a unique four-character extension to each file it encrypts, making the filenames appear with random characters, such as 1.jpg.p67l or 2.docx.2n8h. After encryption, IRIS changes the desktop wallpaper and drops a ransom note named read_it.txt in the affected directories. This note informs victims that their files have been encrypted and demands a ransom of $350, payable in Monero (XMR), a cryptocurrency. The note also warns that the victim’s sensitive data, including browsing history and personal details, has been stolen, implying that formatting the device will not prevent the attackers from leaking this information.

Senator Ransomware is a type of malicious software that encrypts files on a victim's computer, rendering them inaccessible until a ransom is paid. This ransomware is part of a broader category of malware that has been increasingly prevalent in cyberattacks across various sectors. Understanding the mechanics of Senator Ransomware, including its infection process, the encryption it uses, the ransom notes it generates, and the potential for decryption, is crucial for both prevention and remediation. A distinctive feature of Senator Ransomware is its method of renaming the encrypted files. It appends an email address, a victim's ID, and the .SENATOR extension to the filenames. For example, a file originally named document.docx would be renamed to something like document.docx.[email_address].[victim_ID].SENATOR after encryption. This renaming convention is a clear indicator of Senator Ransomware's presence on the system. Senator Ransomware drops a ransom note named SENATOR ENCRYPTED.txt in the directories containing the encrypted files. This note is intended to communicate with the victims, providing them with instructions on how to proceed. It typically includes the ransom amount, expected in cryptocurrency, and detailed instructions on how to contact the attackers through various communication methods, including Session messenger, Telegram, or email. The note is designed to coerce the victim into paying the ransom in exchange for the decryption key.

Bgzq Ransomware is a type of malicious software that targets computers by encrypting files and demanding a ransom for their decryption. It is part of a broader category of malware known as ransomware, which has been a significant threat to individual users, businesses, and organizations worldwide. Upon infection, Bgzq ransomware appends a specific file extension to the encrypted files, which is .bgzq. This marks the files as inaccessible, and they cannot be opened by standard means. The encryption used by Bgzq is robust, utilizing strong cryptographic algorithms to lock files, thereby preventing unauthorized access without the decryption key. Following the encryption process, Bgzq ransomware generates a ransom note named _README.txt, which is placed in folders containing the encrypted files. This note typically contains instructions for the victim on how to pay the ransom and contact the attackers. The note emphasizes that decryption without the attackers' intervention is not possible, urging victims to pay a ransom to retrieve access to their data.

Bgjs Ransomware is a type of malicious software that falls under the broader category of ransomware. It is designed to infiltrate computer systems, encrypt files, and demand a ransom from the victim in exchange for the decryption key. This particular strain is part of the STOP/Djvu family, which is known for its widespread attacks and numerous variants. Upon infection, Bgjs Ransomware appends a distinctive .bgjs file extension to each encrypted file, making them easily identifiable. The ransomware uses the Salsa20 encryption algorithm, which is a stream cipher known for its high performance and security. The use of this algorithm makes the encrypted files inaccessible without the corresponding decryption key. Bgjs Ransomware creates a ransom note named _README.txt and places it in every folder containing encrypted files. This note typically includes instructions on how to contact the attackers, the amount of ransom demanded (often in cryptocurrency), and sometimes a deadline for payment. The note may also offer a test decryption service for a single file as proof that the attackers possess the necessary decryption key.
