Ransomware

PowerLocker Ransomware is a malicious software designed to encrypt victim's files, making them inaccessible until a ransom is paid. This type of malware appends a specific file extension, in this case, .PowerLocker, to each affected file, effectively renaming them in a manner that signals their compromised status, such as turning example.doc into example.doc.PowerLocker. Utilizing the AES-256 encryption method, a robust and secure cryptographic algorithm, PowerLocker ensures that these files cannot be easily decrypted without specific decryption keys, which the attackers hold. Once files are encrypted, victims will find a ransom note created in the form of a text file, IMPORTANT.txt, placed conspicuously on their desktop. The ransom note typically instructs victims to contact the attackers, often through a provided email address, to negotiate payment for the decryption tool that theoretically restores access to the files.

Pres Ransomware is a malicious program that belongs to the Dharma family, notorious for its file-encrypting capabilities. Once it infiltrates a system, it targets a wide range of file types, making them inaccessible to users. It achieves this by encrypting the data and appending the .pres extension to the compromised files. For example, a file named document.docx would be modified to document.docx.id-[unique_ID].[contact_email].pres. This meticulous file renaming method is engineered to distinguish the newly encrypted files from their original state. The ransomware utilizes robust encryption algorithms, common in many high-tier ransomware strains, which renders the data inaccessible without the specific decryption key, usually retained by the cybercriminals. The presence and nature of the encryption used make it nearly impossible to decrypt the files through simple means, necessitating either the involvement of the attackers or the use of specialized decryption tools. Violating the victim's digital space further, Pres Ransomware generates a ransom note, typically as a pop-up window and within a text file named info.txt.

Encountered in the wild by cybersecurity researchers, Lyrix Ransomware is a formidable threat designed to encrypt a user's files and subsequently demand a ransom for restoration. Typically, this ransomware appends an extension consisting of ten random characters to the filenames of encrypted files, transforming them beyond recognition. For instance, a file named document.docx might appear as document.docx.EFsndfh after encryption. Utilizing sophisticated encryption techniques, such as AES or RSA, Lyrix ensures that the affected files cannot be effortlessly decrypted without a specific decryption key—a key possessed solely by the attackers. Following the encryption, the ransomware plants its ransom note in a straightforward text file named README.txt, which can be found among the encrypted files or the desktop. The note's message, albeit varying slightly between different versions, ominously informs the victim of the data's encryption and the extraction of sensitive information, advising against using third-party decryption tools in fear of data corruption.

PLU Ransomware is a malicious software recently identified in the cybersecurity landscape, designed specifically to encrypt critical user files and demand ransom for their decryption. Operating under the guise of a sophisticated threat, it appends the .PLU extension to the affected files, transforming ordinary file names into a series of unintelligible characters, such as 1.jpg becoming 1e6e6c21-04b5-4487-b233-f201db8507be.PLU. This ransomware leverages "military-grade" encryption methods, making it virtually impossible to access the files without the unique decryption key held by the threat actors. Once the attack is complete, it delivers a ransom note titled IMPORTANT.txt, providing victims with detailed instructions on how to contact the attackers via email at pluransom@tutamail.com for negotiations over the decryption fee. The note also changes the desktop wallpaper, creating a constant visual reminder of the hostage state of one's files.

LockZ Ransomware is a malicious software designed to encrypt files on a victim's computer and demand payment for their release. Once it infiltrates a system, it appends the file extension .lockz to each encrypted file, rendering them inaccessible. For example, a file named document.docx would be renamed to document.docx.lockz. The ransomware employs complex encryption algorithms to ensure that victims cannot easily decrypt the affected files without the key. After the encryption process is complete, LockZ changes the desktop wallpaper and drops a ransom note titled @HELP_HERE_TO_RESCUE_YOUR_FILES@.txt. This note informs the victim of the attack and provides instructions on how to pay the ransom to recover their files, typically demanding 1 Bitcoin as payment and threatening to double the ransom if not paid within 48 hours.

AnarchyRansom Ransomware is a malicious program classified under the notorious ransomware category, which targets computers by encrypting data and demanding ransom payments for decryption solutions. When it infiltrates a victim's system, it immediately proceeds to encrypt files, making them inaccessible. This ransomware appends the .ENCRYPTED extension to the compromised files, altering their original filenames and thus rendering them unrecognizable. For example, a document like report.doc becomes report.doc.ENCRYPTED. AnarchyRansom utilizes sophisticated encryption algorithms—either symmetric or asymmetric—to lock the files, making it nearly impossible to reverse the encryption without the unique decryption key held solely by the attackers. Following encryption, AnarchyRansom alters the desktop wallpaper with a demand message and additionally drops a ransom note titled READ-ME!.txt on the victim's desktop. This note warns against using third-party decryption tools and advises immediate contact with the cybercriminals via the provided email, coercing victims into paying the demanded ransom.

RESOR5444 Ransomware represents a growing category of cyber threats known for encrypting valuable data and demanding payment for decryption. Once active on a system, it encrypts the victim's files, adding extensions composed of five random characters, like .WSnPt, to filenames, signaling the files have been compromised. The ransomware employs sophisticated encryption techniques, either symmetric or asymmetric algorithms, to ensure that decryption without the necessary keys is nearly impossible. After successfully encrypting data, RESOR5444 changes the desktop wallpaper and creates a ransom note titled Readme.txt on the victim's desktop or other locations. This note warns the victim that their files are encrypted and that sensitive data might be leaked online unless a ransom is paid. Cybercriminals behind this ransomware strongly advise against involving third parties and request direct contact for payment instructions.

Rans0m Resp0nse (R|R) Ransomware, often stylized as Rans0m Resp0nse (R|R), is a formidable variant of ransomware developed using the source code from the notorious LockBit ransomware families. This sophisticated malware encrypts files on the victim's device, rendering them inaccessible by appending a distinctive, randomly generated string of characters as a new extension (e.g., ".RSN6Lzcyg"). These alterations ensure that even recognizing the original file type becomes challenging. For instance, a file named document.pdf may transition to document.pdf.RSN6Lzcyg, symbolizing its encryption status. Employing advanced encryption methods akin to military-grade security, Rans0m Resp0nse (R|R) leverages strong cryptographic algorithms to secure its grip on essential data. After the encryption process, it drops a ransom note in the form of a text file, titled [random_string].README.txt, which appears in every affected folder. This note notifies the victims of the encryption and provides instructions on paying the ransom, usually demanding payment in Bitcoin within a specific time frame to receive the alleged decryption tool.
