Ransomware

Korea Ransomware is a malicious program that belongs to the notorious Dharma family of ransomware, which is known for encrypting users' files and demanding a hefty ransom in exchange for decryption. This malware appends the .korea extension to the names of all affected files, making them inaccessible to users. For instance, a file named photo.jpg would be altered to photo.jpg.id-1E857D00.[omfg@420blaze.it].korea. The ransomware utilizes sophisticated encryption algorithms, often involving robust asymmetric cryptography, which means each encryption is unique and requires a specific decryption key known only to the attackers. Victims are left with the message in a text file named FILES ENCRYPTED.txt, and a pop-up notification, both of which urge them to contact the hackers via email addresses provided within the note. The ransom note threatens that any tampering or attempts at using unauthorized decryption tools could result in permanent data loss.

QQ Ransomware is a malicious software primarily designed to encrypt the files on an infected computer, denying access to the user until a ransom is paid. Once it infiltrates a system, the ransomware appends an additional file extension of .QQ to affected files, effectively identifying them as encrypted. For instance, a file named example.docx would become example.docx.QQ following encryption. This malware utilizes strong cryptographic algorithms, often making it nearly impossible to decrypt the files without a specific key held by the attackers. After the encryption process, How To Restore Your Files.txt is typically generated and displayed, containing a ransom note that instructs victims on how to contact the cybercriminals to supposedly regain access to their files. It is common for the note to urge victims against using third-party decryption tools or modifying the files, threatening irreversible damage if such steps are taken.

BlackHeart Ransomware belongs to the notorious MedusaLocker family, a group known for its aggressive data encryption tactics. Upon infiltrating a system, this ransomware encrypts files using robust encryption algorithms - commonly a combination of RSA and AES—which ensures that unauthorized users cannot access the data. After encryption, it appends a distinctive .blackheart138 extension to each affected file. For example, a file named document.docx would be transformed into document.docx.blackheart138, making the files inaccessible without the decryption key. The attackers drop a ransom note, typically named read_this_to_decrypt_files.html, in every affected directory. This note contains instructions on how the victim can contact the cybercriminals, usually via email addresses or a Tor-based chat service, to negotiate payment in exchange for a decryption tool. Urging prompt communication within a specified timeframe, the cybercriminals threaten to increase the ransom or even publish the stolen data if their demands are not met.

Danger Ransomware is a destructive type of malware belonging to the GlobeImposter family that encrypts valuable files on an infected system. It operates by modifying files with a new extension, specifically the addition of .danger to each encrypted file, making them inaccessible to the user. The attack process employs sophisticated RSA and AES encryption methods, which ensure the data remains locked without the appropriate decryption key. Alongside its encryption tactics, the ransomware drops a ransom note file titled HOW_TO_BACK_FILES.html onto compromised systems. This note serves as a grim announcement to the victim, stating that their data has been encrypted and detailing the ransom demands, often accompanied by threats to release collected personal data publicly or sell it if payment is refused. The note also provides contact information, urging victims to reach out via specified emails or a Tor-based website to negotiate the ransom payment.

Edfr789 Ransomware represents a significant threat in the spectrum of malware, primarily targeting unsuspecting users to extort money through file encryption. This ransomware, like many of its ilk, encrypts files on the victim's computer, making them inaccessible. It appends four random characters as extensions to the newly encrypted files, such as '.smAf' or '.ZITv', leaving victims with their documents, photos, and videos locked away. The encryption algorithm employed is advanced and robust, ensuring that only specific decryption tools created by the attackers would feasibly render the files accessible again. Once the encryption process is complete, Decryptfiles.txt is a ransom note generated on the affected system, typically placed in each folder containing encrypted files. This document lays out the demands of the cybercriminals, often warning against attempting recovery by any other means apart from purchasing their decryption tool. Victims are advised to contact the attackers within 72 hours via provided email addresses to avert permanent data loss.

Loches Ransomware is a severe malware threat belonging to the GlobeImposter family, which is infamous for encrypting files on infected systems and demanding a ransom for decryption. Once a computer is compromised, it encrypts the victim's data using robust encryption algorithms like RSA and AES, rendering files inaccessible. It appends a distinctive file extension, .loches, to each encrypted file, serving as a marker of the infection. This modification transforms files such that document.docx becomes document.docx.loches, clearly indicating that they have been locked by Loches Ransomware. Victims are then greeted with a ransom note, typically named how_to_back_files.html, which is created and placed in every folder containing encrypted files. This note outlines the attackers' demands, usually requiring payment in cryptocurrency, and sometimes offers to decrypt a few files for proof, while threatening to disclose sensitive data if demands are not met.

FOX (Dharma) Ransomware is a type of malicious software belonging to the notorious Dharma family. Aimed at extorting money from victims, it encrypts files on infected systems and demands a ransom for the decryption key. This ransomware appends a distinctive file extension to the encrypted files, specifically adding the .SCRT extension, making it easy to identify its presence. Not only does it rename files by changing their extensions, but it also adds the victim's unique ID and a contact email address for the attackers, giving the appearance of something like filename.jpg.id-12345678.[contact_email].SCRT. Utilizing robust encryption algorithms typical of the Dharma family, the ransomware ensures that files cannot be easily decrypted without the attacker's intervention. Upon encryption, info.txt, a ransom note, is generated and placed on the victim's desktop and other easily noticeable locations, instructing victims on how to contact the criminals and what steps to follow to regain access to their files. It typically advises the victim to email the provided address, threatening to erase the decryption key if the ransom is not paid, and ominously warns against seeking external help.

Hunters Ransomware, a menacing member of the Xorist ransomware family, has emerged as a formidable threat in the realm of cyber security. Targeting individual and corporate networks, it encrypts files and demands a hefty ransom for a decryptor. This malicious software appends the lengthy extension ..Remember_you_got_only_36_hours_to_make_the_payment_if_you_dont_pay_prize_will_triple_hunters_Ransomware to affected files, rendering numerous essential documents and personal data inaccessible. The extension's conspicuous length not only disrupts file usability but also serves as a psychological tactic to pressure victims. Upon infiltration, HOW TO DECRYPT FILES.txt is deposited onto the victim's desktop and within each contaminated folder, reiterating the severity of the situation. The note spells out a demand for $10,000 in Bitcoin, with contact instructions via the qTOX messenger for further guidance on the payment process. Unlike some ransomware strains for which decryption breakthroughs have been developed, Hunters offers no readily available tool or workaround to decrypt files without capitulating to the extortion demands or having pre-existing backups.
