Viruses

If your files became unavailable, got weird icons, and got .mztu extension, that means your computer got hit by Mztu Ransomware (also known as STOP Ransomware or Djvu Ransomware). This is an extremely dangerous and harmful encryption virus, that encodes data on victims' computers and extorts ransom equivalent of $490/$960 in cryptocurrency to be paid on an anonymous electronic wallet. If you didn't have backups before the infection, there are only a few ways to return your files with a low probability of success. However, they are worth trying, and we describe them all in the following article. In the text box below, you can get acquainted with the contents of _readme.txt file, which is called "ransom note" among security specialists and serves as one of the symptoms of the infection. From this file, users get information about the technology behind the decryption, the price of the decryption, and the contact details of the authors of this piece of malware.

Mzqw Ransomware (aliases: Djvu Ransomware, STOP Ransomware) is an extremely dangerous file-encrypting virus, that extorts money in exchange for decrypter. Ransomware utilizes a strong AES-256 encryption algorithm and makes files unusable without decryption master key. Particular malware in this review appeared in the end of January 2023 and appends .mzqw extensions to files. As a result, file example.jpg converts to example.jpg.mzqw. Mzqw Ransomware creates a special text file, that is called _readme.txt, where hackers give contact details, overall information about encryption, and options for decryption. Threat places it on the desktop and in the folders with encrypted files. Cyber-criminals can be contacted via e-mail: support@freshmail.top and datarestorehelp@airmail.cc.

SecureAgent is a ransomware virus that encrypts system-stored data and blackmails victims into paying money for its decryption. Along with encrypting access to data, the ransomware also assigns the .secured extension to highlight the blocked files. For instance, a file originally named 1.pdf will change to 1.pdf.secured and reset its icon as well. After encryption is done, the virus changes the desktop wallpapers and displays a pop-up window containing decryption guidelines. Overall, the window features a deadline timer for transferring $120 (in Bitcoin) to the cybercriminals' crypto address. After the given time expires, the decryption key for unlocking the data will supposedly be deleted making files permanently inaccessible. Developers behind SecureAgent do not provide any contact information, which makes it unclear how they will send a decryption key after the payment.

Poqw Ransomware (also known as STOP Ransomware) is a cynical virus that knocks out the soil and leaves users at a loss because it affects the most intimate type of information - personal photos, videos, e-mails, as well as documents, archives, and other valuable data. Ransomware is a type of threat that not only encrypts those files, but demands a buyout. STOP Ransomware is officially the most widespread and dangerous virus among the file-encrypting type of malware. There have been more than 500 versions of it and latest struck with .poqw extensions. Such suffixes are added by Poqw Ransomware to files it encodes with its powerful AES-256 encryption algorithm. In 99% of cases, its algorithms are unbreakable, however, with instructions and utilities covered in this article you get this 1% chance of recovery. Firstly look at the ransom note, that Poqw Ransomware copies to the desktop and affected folders.

Being part of the Djvu and STOP virus family, Zouu Ransomware is a file-encrypting virus that has been strolling around the web since the middle of January 2023. In fact, developers distribute a plethora of versions that vary from each other by extensions, cybercriminals' e-mail, and other details. There are over 600 extensions that STOP Ransomware has used to attack the user's data. In our case, STOP Ransomware appends .zouu extension to files so that they become encrypted. For instance, something like 1.mp4 will be retitled to 1.mp4.zouu and reset its default icon after infection. Sequentially, the program creates a note called _readme.txt that contains ransom information. Usually, the generated content looks very similar in all ransomware types.

Zoqw Ransomware, being a part of STOP Ransomware is a critical virus, endangering user's personal files. It belongs to the family of file-encrypting malware, that uses the AES (Salsa20) algorithm and unbreakable key. This virus is, sometimes, called Djvu Ransomware, after the word used as an extension in the first versions (.djvu). The variant of the threat, that we describe today, modifies files with .zoqw extension appeared in first half of January 2023 and acts exactly the same in comparison with dozens of previous versions. Files are encrypted with a secure key and there are quite small chances to decrypt them completely, especially if an online key was used. However, certain manual methods and automatic tools, described in this article can assist you in successfully decrypting some data. In the text box below you can find the "ransom note" - a small text file with a brief virus introduction and instructions to pay the ransom.

One of the main computer security threats today is ransomware. Those are devastating computer viruses, that encrypt users' files using various cryptographic algorithms and extort ransom money for the decryption key. It is especially sensitive for users, as it attacks either personal files such as videos, photos, music, or business data such as MS Office file formats, e-mails, databases. Such files can be crucial for business operation or extremely important personally as part of family memory. Malefactors can demand from several hundred to several thousand dollars as a ransom. STOP Ransomware is officially the most widespread and therefore most dangerous ransomware threat. There've been more, than 650 versions of this virus in 5 years. Each variation infects thousands of computers, and there are millions of victims of this nasty malware. In this article, we will explain typical methods to fight Bpto Ransomware and decrypt affected files. In today's focus, versions of STOP (Djvu), that add .bpto extensions. Recent samples use a very similar pattern to infiltrate PCs and encrypt files. After encryption, ransomware creates a file (ransom note), called _readme.txt.

Theva is the name of a ransomware virus that encrypts system-stored data and demands victims to pay money in Bitcoin for its decryption. During encryption, targeted files end up visually altered - for instance, 1.pdf will change to 1.pdf.[sql772@aol.com].theva and so forth with other files. Upon successful blockage of data, Theva Ransomware represents its decryption instructions in a text document called #_README_#.inf. It also changes victims' desktop wallpapers. In order to recover the data, victims are urged to contact cybercriminals via the given e-mail address (sql772@aol.com) and pay the ransom in Bitcoin cryptocurrency. It is said the price for decryption depends on how fast victims establish contact with swindlers. Following successful payment, threat actors promise to send the necessary decryption tool that will unlock all blocked data.
