Ransomware

Secplaysomware Ransomware is a malicious software that targets computer systems by encrypting files and demanding a ransom from victims in exchange for file decryption. Upon infection, this ransomware appends the .qwerty extension to all affected files, rendering them inaccessible. The ransomware not only encrypts each file, but it also drops a ransom note, typically named UNLOCK_README.txt, in every directory containing encrypted files. This note instructs the victim to contact the attacker via a specific email address to discuss the terms for unlocking the files. However, there's no guarantee that the attacker will provide a decryption key even after payment, making reliance on these cybercriminals risky. Secplaysomware appears to use advanced encryption algorithms commonly found in ransomware, making independent decryption a challenging task without the attackers' private key.

Luck (MedusaLocker) Ransomware is a malicious program belonging to the infamous MedusaLocker ransomware family, which has become notorious for its capability to encrypt valuable data and demand hefty ransoms for decryption. This ransomware, once it infiltrates a system, targets and encrypts the files using robust RSA and AES cryptographic algorithms, rendering user data inaccessible. With its unforgiving nature, it appends a distinct file extension to each locked file. For instance, users may notice their files marked with the extension .luck_06, though variations may occur in different versions. Alongside this encryption process, a ransom note is quietly yet prominently positioned within the compromised directories, typically within an HTML file titled How_to_back_files.html. This note threatens the victim with the loss of data if specific monetary demands are not met within a designated timeframe, further intensifying the urgency by cautioning against any attempts to alter encrypted files or seek unauthorized decryption assistance.

GURAM Ransomware is a malicious software variant that clandestinely infiltrates computer systems with the primary intent of encrypting valuable files and demanding a ransom for their decryption. This ransomware typically appends the .GURAM extension to the encrypted files, transforming a potentially recognizable file such as document.docx into document.docx.{victim's_ID}.GURAM. The encryption process employed by GURAM is robust, leveraging either symmetric or asymmetric cryptographic algorithms, which makes decryption without the appropriate key extremely challenging. Upon encryption, a ransom note is usually deposited in a text file named README.txt, found in each folder containing encrypted files. This note informs victims of their compromised data status and outlines the payment requirements, typically demanding a sizable ransom in cryptocurrency, such as Litecoin, with threats of increasing the amount if payment is delayed.

Crynox Ransomware, a notorious threat in the realm of cybercrime, is a malicious software variant designed to encrypt a victim's files and demand a ransom for their release. This ransomware is based on the Chaos ransomware variant, using sophisticated encryption algorithms to ensure that the victim's data is inaccessible. Once infiltrated, Crynox appends the .crynox extension to the affected files, drastically impacting a user's ability to access their crucial documents, spreadsheets, photos, and more. The encryption process usually employs a combination of RSA and AES, both recognized for their robust security, which presents a significant challenge to reverse engineer or decrypt without the correct keys. Victims typically encounter a ransom note titled read_it.txt placed on their desktop or in all folders containing encrypted files. This note provides instructions from the attackers, often demanding payment in Bitcoin to retrieve the decryption key, and urging victims to follow specific instructions to avoid data loss.

Black (Prince) Ransomware is a malicious software variant designed to manipulate victims through file encryption and extorting ransom payments. Emerging from the Prince ransomware family, it maliciously encrypts files on the victim's computer system, making them inaccessible to users. Upon encryption, it appends a distinct .black extension to the affected files, rendering them unrecognizable to commonly used software. Files like document.pdf or image.jpg become document.pdf.black and image.jpg.black, respectively, signaling the encryption. Targeted file encryption serves as a powerful and disruptive force, leveraging either symmetric or asymmetric cryptographic algorithms to ensure victims are locked out of their own data. This ransomware leaves a comprehensive ransom note titled Decryption Instructions.txt on the desktop, instructing victims on how to regain access to their files by paying a ransom through unspecified cryptocurrency. It strongly advises victims against renaming or manipulating the encrypted files, as this could lead to permanent data loss and further complicate data recovery.

X101 Ransomware is a hazardous form of malware known to encrypt files on affected systems, rendering them inaccessible without a decryption key. This malicious software specifically targets stored files by appending the extension .X101 to each. During the encryption process, it uses a robust algorithm called TermCryptV101 combined with RSA2048 for heightened security, making the decryption process particularly challenging without the correct key. Victims are typically met with a ransom note labeled !!!HOW_TO_DECRYPT!!!.TXT, placed conspicuously in folders containing encrypted files to ensure it grabs attention. The note details instructions demanding a ransom payment of $250 in Bitcoin to recover the data, providing contact details via Telegram and Jabber for negotiations. It discourages using third-party tools or services and warns against renaming files, cautioning that these actions might cause irretrievable data loss. Despite the temptation to comply with the attackers' demands, paying the ransom does not guarantee data recovery, as these criminals may fail to provide the necessary decryption keys even after payment.

Starcat Ransomware is a malicious program identified as a form of ransomware that targets computer systems, encrypting files to extort money from victims. Once this ransomware infiltrates a system, it appends a specific extension, .starcat, to each encrypted file, rendering the user unable to access their personal data without a decryption key. Utilizing the advanced CHACHA20+RSA4096 encryption algorithm, Starcat ensures that decrypting affected files without the attackers’ designated key becomes virtually impossible. Victims of this ransomware will notice a change in their desktop wallpaper, along with the creation of a ransom note titled recover files,view here.txt. This note, written in multiple languages including English, Russian, and Chinese, demands a hefty sum of $5,000 in XMR (Monero) to decrypt the files and threatens victims with public exposure of their files if they fail to comply in a timely manner.

Help_restoremydata Ransomware is a malicious software program designed to encrypt files on an infected computer, rendering them inaccessible without a specific decryption key. This ransomware appends the .help_restoremydata extension to the names of the files it encrypts, effectively locking the user out of their data. For example, a file originally named document.docx would be renamed to document.docx.help_restoremydata. The encryption process utilized by Help_restoremydata employs robust cryptographic algorithms, specifically RSA-4096 and AES-256, which makes it difficult to decrypt without the appropriate decryption key. Upon completing the encryption, the ransomware leaves a HOW_TO_RECOVERY_FILES.html file as a ransom note, both on the desktop of the infected computer and within the folders containing the encrypted files. This note demands payment in cryptocurrency, typically Bitcoin, and warns users not to attempt file recovery using third-party software, as this could result in permanent data loss.
