Dark Intel Ransomware is a malicious program that aggressively targets personal data by encrypting files on infected devices. Upon attack, it appends the .encrypted extension to affected files, transforming them from accessible formats like .jpg or .png into unreadable files like 1.jpg.encrypted. This encryption technique prevents the victim from opening their files without a decryption key, effectively holding their data hostage. Dark Intel uses complex encryption algorithms, which are designed to be nearly impossible to break without the specific decryption key held by the attackers. Victims are left with dramatically altered file names and a ransom note ominously titled Ezz.txt, which typically appears on the desktop and inside encrypted directories. The note claims ownership of the hacked data and threatens its destruction if the ransom is not paid within a stipulated timeframe, often 48 hours, demanding a seemingly small ransom of 0.000010 BTC, which can add up across numerous victims.

In the realm of evolving cyber threats, AlienWare Ransomware emerges as a particularly insidious form of malware. This ransomware variant is based on the Chaos framework, and upon infiltrating a computer system, it encrypts various file types, rendering them inaccessible. It appends a unique set of four random characters as new file extensions, effectively altering and isolating each file from user access. For instance, a document such as report.docx might be transformed into report.docx.a1b2 after encryption, leaving its contents inaccessible without the appropriate decryption key. AlienWare's attack does not stop at mere encryption; it also alters the user's desktop wallpaper as a stark notification of the attack, increasing the psychological pressure on the victim. After encryption, the ransomware delivers a ransom note, read_it.txt, onto the desktop, further directing victims on how to pay the ransom for file decryption.

Xcvf Ransomware is a malicious software variant that belongs to the notorious Djvu ransomware family. Its primary function is to encrypt personal files on a victim's computer, rendering them inaccessible and essentially useless without a decryption key. Upon infection, the ransomware appends the .xcvf extension to each encrypted file, altering the original format and making it evident that the file has been compromised. For instance, a file previously named photo.jpg would be transformed into photo.jpg.xcvf. This encryption process is typically accompanied by the creation of a ransom note, which is commonly titled _readme.txt. This file is usually placed in every folder that contains encrypted files, serving as a grim notification to the victim. The ransom note details the demands of the cybercriminals, often requesting a payment in exchange for a decryption key, with prices generally set at $980, though it can be reduced to $490 if contact is made within a specified timeframe.

Bnrs Ransomware is a malicious software identified as part of the Djvu ransomware family that encrypts files on an infected system, rendering them inaccessible until a ransom is paid. Upon infection, this ransomware appends the .bnrs extension to the names of encrypted files, effectively altering them and making them unusable without decryption. For example, a file named document.pdf would become document.pdf.bnrs after encryption. The ransomware employs sophisticated encryption algorithms, typically using a combination of symmetric and asymmetric cryptography, which makes decrypting the files without the decryption key extremely challenging. After the encryption process, Bnrs Ransomware creates a ransom note titled _readme.txt in affected directories, detailing instructions for victims on how to recover their files by contacting the attackers and paying a specified ransom amount, usually in Bitcoin.

Locklocklock Ransomware is a malicious program designed to encrypt files on a victim's computer, demanding a ransom payment for their decryption. This type of malware targets a broad range of file types and appends a unique extension to them, making affected documents, images, and other files inaccessible to users. Specifically, it appends the .locklocklock extension to each encrypted file, for example, changing document.pdf to document.pdf.locklocklock. The ransomware employs sophisticated encryption algorithms that securely lock data, often leaving minimal chances for victims to retrieve their data without the encryption key. Upon encryption, Readme-locklocklock.txt, the ransom note, typically appears on the desktop or in the affected folders. This note informs victims about the encryption, demands a ransom payment in cryptocurrencies, and threatens data exposure on the dark web if the ransom is not paid.

DarkN1ght Ransomware is a malicious software variant that encrypts files on infected computers, making them inaccessible to the user unless a ransom is paid. This ransomware is based on the Chaos ransomware family and exhibits behaviors typical of modern ransomware threats, meticulously encrypting critical data and demanding a ransom for decryption. Upon infiltrating a system, DarkN1ght appends file extensions composed of four random characters to encrypted files, examples of which include extensions such as .3hok, .7oyv, and .6003. After encryption, affected files might be renamed from, say, 1.jpg to 1.jpg.3hok, exemplifying the alteration that occurs. This renaming serves as a clear indicator that the files are no longer directly accessible. The process of encryption utilized by DarkN1ght is assumed to be complex, possibly employing an asymmetric encryption algorithm, though specific details on its cryptographic methods remain undisclosed by researchers. In terms of communication, DarkN1ght Ransomware drops a poignant ransom note named read_it.txt on the victim's desktop and within various directories across the system.

Adver Ransomware is a malicious software strain that targets personal files by encrypting them, rendering the data inaccessible unless a decryption tool is obtained, typically through payment. When it infects a system, it appends the .adver file extension to all encrypted files; for example, a file named photo.jpg would become photo.jpg.adver. This encryption process is meticulous, employing sophisticated and often unbreakable algorithms, making manual decryption practically impossible without the correct decryption key. Victims of Adver Ransomware find a note titled RECOVERY INFORMATION.txt placed within their system, which outlines the extortion demands. This note usually details how to contact the perpetrators, typically through an email address provided, and instructs victims on paying the ransom amount in exchange for the decryption tool. Unfortunately, victims face additional distress knowing that paying the ransom does not guarantee the recovery of their files and only encourages criminal activity.

Novalock Ransomware is a malevolent strain of ransomware belonging to the notorious GlobeImposter family. Typically targeting business networks, this malware encrypts files on compromised systems and appends them with the .novalock file extension, effectively rendering the files unusable without the decryption key. For example, photo.jpg would be altered to photo.jpg.novalock, instantly indicating a breach. Under the hood, Novalock employs a hybrid encryption scheme, utilizing both RSA and AES algorithms. This combination ensures a highly secure encryption process, significantly complicating efforts to decrypt without the proper key. Once the encryption is complete, a ransom note titled how_to_back_files.html is generated on the affected system. This note is strategically placed in folders containing encrypted files, warning victims that the attacker has accessed their network, encrypted critical data, and stolen information that may be leaked publicly if the ransom is not paid.
