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 stop Hello Perv e-mail spam

0
Hello Perv email scam, also known as a sextortion scam, is a fraudulent campaign targeting the general public, businesses, and IT professionals alike. This scam involves sending mass emails to individuals, falsely claiming that the sender has compromising videos or information about the recipient's online activities, specifically related to pornography. The scam aims to extort money, typically in the form of Bitcoin, by threatening to release the supposed evidence to the recipient's contacts or the public if a payment is not made within a specified timeframe.

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".

How to remove Avira9 Ransomware and decrypt .Avira9 files

0
Avira9 Ransomware is a type of malicious software designed to encrypt files on a victim's computer, rendering them inaccessible. It is named after the file extension it appends to encrypted files. The attackers then demand a ransom from the victim in exchange for a decryption key, which is promised to restore access to the encrypted data. Upon encrypting a file, Avira9 appends a unique extension to the file name, typically .Avira9, making the file easily identifiable but inaccessible. The ransomware employs robust encryption algorithms, such as AES (Advanced Encryption Standard), RSA, or a combination of both, to lock the files. This encryption method is practically unbreakable without the corresponding decryption key, making the attacker's offer the only apparent solution to recovering the files. Avira9 Ransomware generates a ransom note, usually a text file named readme_avira9.txt or similarly, placed in every folder containing encrypted files or on the desktop. This note contains instructions for the victim on how to pay the ransom, usually in cryptocurrencies like Bitcoin, to receive the decryption key. It also often includes warnings about attempting to decrypt files using third-party tools, claiming that such attempts could lead to permanent data loss.

How to remove Wiaw Ransomware and decrypt .wiaw files

0
Wiaw Ransomware is a type of malicious software that belongs to the Stop/Djvu family of ransomware. It is designed to encrypt files on a victim's computer, rendering them inaccessible, and then demands a ransom from the victim to restore access to the encrypted files. Upon infection, Wiaw Ransomware adds the .wiaw extension to the files it encrypts. The encryption method used by Wiaw Ransomware is not explicitly detailed in the provided sources, but being part of the Stop/Djvu family, it likely employs a combination of AES and RSA encryption algorithms to lock files securely. Wiaw Ransomware creates a ransom note titled _readme.txt, informing victims of the encryption and demanding payment for a decryption tool. The note typically contains instructions on how to pay the ransom, often in cryptocurrency, and threatens permanent data loss if the demands are not met. Wiaw Ransomware is a dangerous malware that encrypts files and demands a ransom. While decryption tools exist, their effectiveness can vary, and prevention through good cybersecurity practices remains the best defense.

How to remove Wisz Ransomware and decrypt .wisz files

0
Wisz Ransomware is a type of malware that encrypts files on the victim's computer, appending the .wisz extension to the filenames. It targets personal photos, documents, databases, and other critical files, making them inaccessible without a decryption key, which the attackers offer in exchange for a ransom payment. Upon infection, Wisz Ransomware initiates a robust encryption process using the Salsa20 encryption algorithm. It scans the system for high-value files and encrypts them. This encryption renders the files inaccessible to the victims. After encrypting the files, WISZ ransomware drops a ransom note named _readme.txt in the directories containing encrypted files. This note includes instructions for contacting the attackers via email and the ransom amount, typically demanded in Bitcoin. The ransom usually ranges from $499 to $999, with a discount offered for prompt payment. This article provides an in-depth analysis of WISZ ransomware, including its infection methods, encryption techniques, ransom demands, and potential decryption solutions.
