How to remove RSA-4096 Ransomware and decrypt .RSA-4096 files

0
RSA-4096 Ransomware is a variant of the Xorist ransomware family, which is known for encrypting victims' data and demanding a ransom for the decryption key. This particular strain uses the RSA-4096 encryption algorithm, which is a part of the asymmetric RSA cipher with a key size of 4096 bits, making it very secure and difficult to crack. When RSA-4096 ransomware encrypts files, it appends the .RSA-4096 extension to the filenames. For example, a file originally named 1.jpg would be renamed to 1.jpg.RSA-4096. After encrypting files, RSA-4096 ransomware drops a ransom note titled HOW TO DECRYPT FILES.txt on the victim's desktop or within encrypted directories. This note explains that the files have been encrypted and provides instructions on how to pay the ransom to receive the decryption key. Victims are instructed to pay 2 BTC (about $124,000 at the time of writing) within 48 hours for the decryption key. However, paying does not guarantee file recovery, and removal of the ransomware does not decrypt the files. The only reliable recovery method is from backups.

How to remove Payuranson Ransomware and decrypt .payuranson files

0
Payuranson Ransomware is a type of malware that belongs to the Skynet ransomware family. Upon successful infiltration, Payuranson Ransomware initiates a sophisticated encryption routine. It typically targets a wide array of file types, including documents, images, videos, and databases, to maximize the impact of the attack. The ransomware appends a specific file extension to encrypted files, usually .payuranson, which serves as a clear indicator of infection. The encryption algorithm employed by Payuranson Ransomware is often advanced, using combinations of RSA and AES encryption methods. These are cryptographic algorithms known for their robustness, making unauthorized decryption exceptionally challenging without the unique decryption key held by the attackers. Following the encryption process, Payuranson Ransomware generates a ransom note, typically named SkynetData.txt or a similar variant, and places it in every folder that contains encrypted files. This note includes instructions on how to contact the attackers, usually via email or a Tor-based payment site, and the amount of ransom demanded, often in cryptocurrencies like Bitcoin. The note may also contain threats of data deletion or exposure to compel victims into paying the ransom.

How to remove LockBit 4.0 Ransomware and decrypt .xa1Xx3AXs files

0
LockBit 4.0 represents the latest iteration in the LockBit ransomware family, known for its highly automated and fast encryption processes. This ransomware operates as part of a Ransomware-as-a-Service (RaaS) model, allowing affiliates to deploy the malware against targets in exchange for a share of the ransom payments. LockBit 4.0 Ransomware is notorious for its efficiency and for incorporating evasion techniques that enable it to bypass security measures and encrypt files undetected. Upon successful infection, LockBit 4.0 appends a unique file extension to encrypted files, which has been observed to vary with each campaign. An example of such an extension is .xa1Xx3AXs. This makes the encrypted files easily identifiable but inaccessible without decryption keys. The ransomware uses a combination of RSA and AES encryption algorithms. AES is used to encrypt the files themselves, while RSA encrypts the AES keys, ensuring that only the attacker can provide the decryption key. LockBit 4.0 generates a ransom note named xa1Xx3AXs.README.txt or a similarly named file, which is placed in each folder containing encrypted files. This note contains instructions for contacting the attackers via a Tor website and the amount of ransom demanded, often in cryptocurrencies. The note may also include threats of leaking stolen data if the ransom is not paid, a tactic known as double extortion. This article provides an in-depth analysis of LockBit 4.0 Ransomware, covering its infection methods, the file extensions it uses, the encryption standards it employs, the ransom note details, the availability of decryption tools, and guidance on how to approach the decryption of files with the extension ".xa1Xx3AXs".
