How to remove Rzml Ransomware and decrypt .rzml files

0
Rzml Ransomware is a malicious software that belongs to the Djvu family. When a computer is infected, Rzml encrypts files and adds the .rzml extension to their names, making them inaccessible. For instance, 1.jpg becomes 1.jpg.rzml and 2.png turns into 2.png.rzml. Apart from encrypting files, Rzml also creates a ransom note in the form of a text file named _readme.txt. The distribution of Rzml might involve information stealers like Vidar and RedLine. Rzml ransomware encrypts files using the AES-256 algorithm (CFB mode). This encryption method is highly secure and difficult to break without the decryption key. Currently, there is no guaranteed method to decrypt .rzml files without the decryption key provided by the attackers. However, it is not recommended to pay the ransom, as there is no guarantee that the attackers will provide the decryption key or that it will work as intended.

How to remove Rzfu Ransomware and decrypt .rzfu files

0
Rzfu Ransomware is a malicious file-encrypting virus that belongs to the Djvu family. It is a variant of the STOP/DJVU malware lineage. When this ransomware infects a computer, it encrypts files using a strong AES-256 encryption key algorithm and appends the .rzfu extension to their filenames. For example, 1.jpg becomes 1.jpg.rzfu and 2.png changes to 2.png.rzfu. The ransomware encrypts various file types, such as videos, photos, and documents. Encrypted files become inaccessible and unusable without the decryption key. Rzfu Ransomware creates a ransom note in the form of a text file named _readme.txt. The note informs victims that all their files are encrypted with strong encryption and that the only way to recover them is to purchase a decrypt tool and a unique key. The ransom demand starts at $980, and victims are given a 50% discount if they pay within 72 hours.

How to stop “YouPorn” sextortion e-mail spam

0
YouPorn sextortion email spam is a type of scam where cybercriminals send fraudulent emails pretending to be from the adult site YouPorn. The scammers claim that a sexually explicit video of the recipient was uploaded to the site and demand payment in Bitcoin to have it taken down. These emails are scams, and the recipients should not make any payments to the listed Bitcoin addresses. Spam campaigns typically infect computers by sending emails with malicious attachments or links. When a user opens the attachment or clicks on the link, it can trigger the download and installation of malware, such as Emotet, TrickBot, or Qbot. These malware infections can lead to further issues, such as ransomware attacks or data theft.

How to remove Rzew Ransomware and decrypt .rzew files

0
Rzew Ransomware is a malicious software belonging to the Djvu family, designed to encrypt a victim's data and render it inaccessible until a ransom is paid to the attacker. It targets various types of files, such as documents, videos, and photos, and adds the .rzew extension to each encrypted file, making them inaccessible and unusable without the decryption key. Rzew Ransomware uses the Salsa20 encryption algorithm to encrypt files. Although not the strongest method, it still provides an overwhelming number of possible decryption keys, making it extremely difficult to decrypt files without the correct key. After encrypting files, Rzew Ransomware creates a ransom note, a text file named _readme.txt, which informs the victim that their files have been encrypted and demands a ransom payment ranging from $490 to $980 in Bitcoin. The ransom note is placed in all folders containing encrypted files.

How to remove Rzkd Ransomware and decrypt .rzkd files

0
Rzkd Ransomware is a malicious software that belongs to the STOP/DJVU ransomware family, which is known for its widespread distribution and high volume of attacks. It targets Microsoft Windows operating systems and encrypts files on the victim's computer, demanding a ransom payment in exchange for a decryption key to restore access to the encrypted files. The ransomware appends the .rzkd extension to the filenames of encrypted files, rendering them inaccessible. For example, it transforms files such as 1.jpg into 1.jpg.rzkd and 2.png into 2.png.rzkd. The encryption algorithm used by Rzkd is Salsa20. Rzkd creates a ransom note, which can be found in a file named _readme.txt. The note provides instructions for contacting the attackers via email addresses (support@freshmail.top and datarestorehelp@airmail.cc) and emphasizes that restoring the encrypted files is only possible with decryption software and a unique key obtained from the cybercriminals behind the attack. The ransom amount ranges from $490 to $980 in Bitcoin.

How to remove Deadnet Ransomware and decrypt .deadnet26 files

0
Deadnet Ransomware is a malicious program that belongs to the MedusaLocker Ransomware family. It is designed to encrypt data and demand payment for its decryption. The ransomware primarily targets companies rather than home users. The impact of Deadnet Ransomware on victim organizations can be significant, leading to financial losses, disruption of operations, and reputational damage. Deadnet Ransomware uses a hybrid encryption scheme, which is common among modern ransomware. This scheme combines symmetric encryption algorithms like AES with asymmetric encryption algorithms like RSA. Although the specific encryption algorithm used by Deadnet Ransomware is not well-studied, this hybrid approach makes it more difficult for researchers and specialists to decrypt the affected files without paying the ransom. Deadnet Ransomware encrypts files and adds the .deadnet26 extension to their filenames. After the encryption process is completed, Deadnet Ransomware drops a ransom note titled HOW_TO_BACK_FILES.html.
