How to remove ReadText Ransomware and decrypt .readtext4 files

0
ReadText Ransomware is a malicious program that belongs to the MedusaLocker ransomware family. It targets companies and utilizes double-extortion tactics to encrypt important files on the victim's computer and demand a ransom for their decryption. ReadText Ransomware appends the .readtext4 extension to the original filenames of the encrypted files. The number in the extension may vary depending on the ransomware variant. While the specific encryption method used by ReadText Ransomware is not known, modern ransomware typically employs a hybrid encryption scheme, combining symmetric encryption algorithms like AES with asymmetric encryption algorithms like RSA. After encrypting the files, ReadText Ransomware drops a ransom-demanding message named How_to_back_files.html.

How to remove Mzqt Ransomware and decrypt .mzqt files

0
Mzqt Ransomware is a variant of the Djvu ransomware family that encrypts files on the victim's computer and demands a ransom for their decryption. It appends the .mzqt extension to the encrypted files, making them inaccessible. For example, a file named sample.jpg would be renamed to sample.jpg.mzqt. The ransomware also generates a ransom note named _readme.txt containing instructions on how to contact the attackers and initiate a partial payment. Mzqt Ransomware uses an advanced encryption algorithm to encrypt users' data, rendering the files useless. It belongs to the Stop/Djvu family, which is known for its advanced cryptographic algorithm. It is essential to remove the ransomware from the infected system before attempting any file recovery methods. A powerful malware removal tool can help scan the computer and delete all threats at once.

How to remove Mzre Ransomware and decrypt .mzre files

0
Mzre Ransomware is a malicious software that encrypts files on infected computers, rendering them inaccessible. It is a variant of the Djvu ransomware family and is known to append the .mzre extension to the filenames of encrypted files. For example, a file named 1.jpg would be changed to 1.jpg.mzre. Mzre Ransomware may also be distributed alongside information-stealing malware like Vidar and RedLine. Mzre Ransomware encrypts files using a powerful cryptography algorithm and adds extensions to the filenames. This makes the files inaccessible and forces victims to pay a ransom to regain access to their data. Upon encrypting the files, Mzre Ransomware creates a ransom note named _readme.txt. The note provides information on how to establish contact with the attackers and outlines the decryption costs.

How to remove NIGHT CROW Ransomware and decrypt .NIGHT_CROW files

0
NIGHT CROW Ransomware is a malicious software designed to encrypt data on a victim's computer and demand payment for its decryption. It appends the .NIGHT_CROW extension to the encrypted files, making them inaccessible. For example, a file initially named sample.docx would become sample.docx.NIGHT_CROW. After encrypting the files, NIGHT CROW drops a ransom note titled NIGHT_CROW_RECOVERY.txt on the infected system. Although the specific encryption algorithm used by NIGHT CROW is not yet discovered, ransomware typically employs strong encryption algorithms, such as AES, to lock the victim's files. The ransom note created by NIGHT CROW informs the victim that their files have been encrypted but reassures them that the data is recoverable. The note instructs the victim to pay a 0.000384 BTC (Bitcoin cryptocurrency) ransom, which is approximately 10 USD at the current exchange rate. This amount is relatively low compared to other ransomware demands.

How to remove Azop Ransomware and decrypt .azop files

0
Azop Ransomware is a malicious software program that encrypts files on targeted computer systems, rendering them inaccessible. It is a member of the STOP/Djvu malware family and is known for its strong encryption capabilities. Azop Ransomware appends the .azop extension to the encrypted files, making them unreadable and unusable. For example, it changes 1.jpg to 1.jpg.azop and 2.png to 2.png.azop. Azop Ransomware uses the Salsa20 encryption algorithm to encrypt files. This strong encryption method makes it particularly difficult, if not impossible, to find the decryption key without cooperating with the attackers. Azop Ransomware creates a ransom note in the form of a text document named _readme.txt. The note contains instructions on how to contact the criminals behind Azop and pay a ransom in exchange for the decryption key.

How to remove LostTrust Ransomware and decrypt .losttrustencoded files

0
LostTrust Ransomware is a type of malicious software designed to encrypt data on a victim's computer, making it inaccessible until a ransom is paid. The primary goal of this ransomware is to extort money from victims by encrypting their files and demanding payment for decryption. LostTrust Ransomware appends the .losttrustencoded extension to the encrypted files. The specific encryption algorithm used by LostTrust Ransomware is not yet investigated. However, ransomware often uses complex encryption algorithms, such as AES and RSA, to encrypt files. LostTrust Ransomware creates a ransom note named !LostTrustEncoded.txt. The note informs victims that the attackers have acquired a significant amount of crucial data from their network and promises to provide a detailed list of the compromised files upon request.

How to remove Mzhi Ransomware and decrypt .mzhi files

0
Mzhi Ransomware is a type of malicious software designed to encrypt files, rendering them inaccessible to the victim. Its primary aim is to extort money from the victim in exchange for the decryption key to unlock the encrypted files. Mzhi Ransomware is similar to other ransomware strains like Mzqt, Azqt, and Mzqw, which also encrypt files and demand ransom payments. Mzhi Ransomware appends the .mzhi extension to the filenames of the encrypted files. This ransomware typically uses strong encryption algorithms like AES or RSA to encrypt the victim's files, making it nearly impossible to decrypt them without the correct key. Mzhi Ransomware creates a ransom note named _readme.txt and drops it in various directories on the infected computer. The ransom note informs the victim that their files have been encrypted and demands a ransom payment, usually in the form of cryptocurrency, to provide the decryption key.

How to remove Azhi Ransomware and decrypt .azhi files

0
Azhi Ransomware is a malicious software that belongs to the STOP/Djvu ransomware family. It infiltrates computer systems and encrypts various file types, such as documents, spreadsheets, presentations, images, photos, and videos. The encrypted files are appended with the .azhi extension, making them inaccessible and unusable. For example, it renames 1.jpg to 1.jpg.azhi and 2.png to 2.png.azhi. Azhi ransomware uses the Salsa20 encryption algorithm to scramble the contents of the targeted files. Due to the strong ciphering method, it becomes particularly difficult, if not impossible, to find the decryption key without cooperating with the attackers. The primary objective of Azhi ransomware is to demand a ransom payment from its victims, ranging from $490 to $980 in Bitcoin. Azhi ransomware creates a ransom note in the form of a text document named _readme.txt. The note clarifies that all files have been encrypted with a strong and unique encryption method and instructs victims to buy a decryption tool along with a key to restore their files.
