Ransomware

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.

Lucky Ransomware, part of the MedusaLocker family, is a notorious type of malicious software that encrypts data on the infected device and demands a ransom for the decryption key. Once executed, it appends the .lucky777 extension to the locked files, altering their original formats and rendering them inaccessible. For instance, a file named document.txt will become document.txt.lucky777. The ransomware employs advanced encryption algorithms, typically RSA and AES, to secure the victim's files, forcing many to consider paying the demanded ransom due to the impracticality of breaking this encryption without the original decryption keys. Even after payment, there is no assurance that the cybercriminals will provide the proper decryption key or tool. Upon encryption completion, READ_NOTE.html is dropped onto the desktop as a ransom note, informing victims about the encryption and the steps needed to restore their files.

NailaoLocker Ransomware is a malicious program that encrypts users' files to demand a ransom for decryption. Identified in ransomware infections, it uses the .locked file extension to lock up victim files. When a file is encrypted by this ransomware, its name is appended with a .locked extension, signifying it has been compromised. Developed using the C++ programming language, NailaoLocker employs a symmetric encryption algorithm, which is notorious for being complex and secure. The attacker's goal is to make it virtually impossible for victims to decrypt their files without the corresponding decryption tool that they claim to provide upon payment. This encryption means that reversing the effects requires a specific key stored by the attackers, making unauthorized decryption highly challenging. Victims of this ransomware are greeted with a ransom-note.txt file after their files have been encrypted.

ETHAN Ransomware is a malicious software threat classified under the MedusaLocker ransomware family. It is specifically designed to infiltrate computer networks, encrypt files, and demand ransom payments from victims in exchange for file decryption. This ransomware uses a combination of RSA and AES cryptographic algorithms, which are often employed to ensure that once data is encrypted, decryption becomes exceedingly difficult without the correct key. In a typical attack, files on an infected system are targeted for encryption, and as part of this process, their original filenames are altered by appending the extension .ETHAN — for instance, a file named document.docx becomes document.docx.ETHAN. Following the encryption, READ_NOTE.html, a ransom note file, is generated and placed in various locations on the affected system, often accompanied by changes to the desktop wallpaper to further alert the user to the breach. This ransom note informs victims that their files have been encrypted and that personal or company data might have been exfiltrated, thus exerting additional pressure to comply with the payment demands.

CipherLocker Ransomware is a malicious software program designed to encrypt files on an infected computer, effectively rendering them inaccessible until a ransom is paid. Victims will notice that encrypted files have the extension .clocker appended to their original filenames, indicating that they are under the ransomware's lock. For example, a file named example.docx would appear as example.docx.clocker once encrypted. Typically employing robust encryption algorithms, CipherLocker Ransomware makes decryption without a specific key practically impossible. This ransomware drops a ransom note titled README.txt in the infected directories, which informs the victim of the situation and demands a payment of Bitcoin to restore access to the files. The note often includes detailed payment instructions, a deadline, and a warning against attempting to decrypt the files using unauthorized software, underscoring the potential loss of data.
