Ransomware

Revenge Of Heisenberg Ransomware is a deceptive and malicious program designed to encrypt files on an infected computer and subsequently demand a ransom for their decryption. This ransomware has been discovered as one of the numerous threats based on the Chaos ransomware builder. Upon infection, it immediately encrypts the user's files and appends each with an extension of four random characters — examples include file names changing from 1.jpg to something like 1.jpg.nw2n. These alterations make the files inaccessible without obtaining the decryption key. The malware alters the desktop wallpaper and deposits a ransom note, typically titled read_it.txt, on the desktop to inform victims about the encryption and provide instructions on how to recover their data. This note explains that the decryption tools must be purchased from the attackers, usually for a specified sum in Bitcoin cryptocurrency; however, due to the volatile nature of Bitcoin exchange rates, the exact cost may fluctuate significantly.

REDKAW Ransomware is a type of malicious software designed to encrypt a victim's files and demand a ransom for their decryption. This ransomware typically adds a specific extension, .redkaw, to all affected files, rendering them inaccessible without the decryption key. The encryption process employed by REDKAW is highly secure, often utilizing advanced algorithms that make cracking the encryption without the decryption key practically impossible. Upon encrypting the files, the ransomware drops a ransom note, often named HOW-TO-FIX.txt, which is strategically placed in affected directories and on the desktop for maximum visibility. The note contains instructions detailing how victims can make the ransom payment, typically asking for a small amount to be paid in cryptocurrency, and warns against attempting any form of data recovery without the specified tools, under threat of permanent data loss.

Agho Ransomware is a malicious software variant belonging to the Djvu ransomware family, known for its aggressive encryption tactics designed to extort money from victims. This ransomware targets Windows operating systems, encrypting valuable files and appending them with the .agho file extension, rendering them inaccessible. The encryption process uses a robust algorithm that makes it nearly impossible to decrypt files without the unique decryption key held by the attackers. After encryption, the ransomware drops a ransom note named _readme.txt into every affected folder. This note informs victims that their files are encrypted and demands a ransom payment in exchange for the decryption tool and key, typically setting the price at $980, reduced to $490 if contact is made within the first 72 hours. The note also includes contact emails for the cybercriminals, encouraging victims to test decryption by sending one encrypted file, although this is a risky move as it does not guarantee that the rest of the files will be decrypted upon payment.

Purgatory Ransomware is a notorious type of malware that encrypts files on an infected system, demanding a ransom payment for the decryption key needed to recover the locked data. This ransomware appends a distinctive .purgatory extension to the files it encrypts, causing significant turmoil for users who find their documents, photos, and other personal files suddenly inaccessible. Once it infiltrates a system, ransom note is promptly displayed through a pop-up window, informing the victim of the encryption and providing instructions on how to pay the ransom. This message typically indicates that all files have been encrypted using a complex cryptographic algorithm, while the unique decryption key is held solely by the attacker, making self-decryption a challenging task without paying the ransom, which supports criminal activities.

Dark 101 Ransomware is a malicious software program that operates by encrypting files on infected systems and then demanding a ransom payment, often presenting itself through hacktivist inspired messages. Based on the Chaos ransomware variant, this specific malware appends file names with a unique extension comprised of four random characters, altering something like photo.jpg into photo.jpg.9xdq. This encryption method creates significant challenges for victims, as it utilizes robust cryptographic algorithms to block access to files until the decryption key is provided—allegedly after ransom payment. Upon completion of the encryption process, the ransomware delivers its ransom note through a text file named Dark101_read_it.txt, left on the infected computer's desktop, and alters the desktop wallpaper with further instructions.

Mania Crypter Ransomware is a dangerous type of malware originating from the notorious LockBit Black family, known for its highly sophisticated file encryption capabilities. This malicious software is designed to encrypt files on the victim's computer, effectively preventing access by appending a random string of characters as a new file extension. Examples of such changes include transforming 1.jpg into 1.jpg.utZMwPnzM and 2.png into 2.png.utZMwPnzM. The primary aim is to extort money from victims who are desperate to regain access to their important files. The ransomware works by using complex encryption algorithms, making it challenging to decrypt the affected files without the necessary decryption keys that are typically held by the attackers. Affected users often find a ransom note, typically named [random_string].README.txt, which is strategically placed on the desktop to grab immediate attention. This note contains instructions for making a Bitcoin payment, which is generally set at $300, to a specified crypto wallet, and warns against attempting manual decryption or renaming of files, which could lead to permanent data loss.

Innok Ransomware is a malicious software that encrypts files on the victim’s computer, appending a specific extension to the affected files to signify that they are under ransomware control. This ransomware is part of a broader category known as cryptoviruses, which are designed to render files inaccessible without proper decryption. When Innok Ransomware infiltrates a system, it appends the .innok extension to each encrypted file. For example, a file named picture.jpg becomes picture.jpg.innok after encryption, making it unusable without a decryption key. The ransomware typically employs robust encryption algorithms, often making use of either symmetric or asymmetric cryptography to lock the data securely and prevent victims from accessing their files without the decryption software or key. Upon completion of the encryption process, the ransomware alters the desktop wallpaper, replacing it with a ransom note titled innok_Help.txt, which explains the encryption situation and demands a ransom for decrypting the files. This note can be found on the desktop and is also shown on an overlay screen that appears before user account sign-in.

Ebola Ransomware belongs to the notorious Dharma family, known for its damaging effect on personal and corporate data. Understanding Ebola Ransomware begins by recognizing its method of operation, which is both sophisticated and malicious. As with many ransomware types, little can be done once files are encrypted without external tools or measures in place beforehand. During the attack, it attaches an ID number, an email address, and the: .ebola file extension to the compromised files, transforming, for example, a file named photo.jpg into photo.jpg.id-[unique_id].[email].ebola. Primarily, the ransomware employs robust encryption algorithms that are difficult or nearly impossible to crack without a decryption key. This encryption renders files inaccessible to users, thereby compelling victims to consider paying the ransom. The malware disseminates a ransom message in a pop-up window and also generates a text file named FILES ENCRYPTED.txt, which users typically find on their desktop or in key directories. Despite these intimidating tactics, victims are discouraged from engaging directly with the perpetrators since paying the ransom does not guarantee file recovery and could potentially fund further criminal activities.
