The number of queries related to new ransomware activity is growing each day with new infections. This time around, users are dealing with Tycx Ransomware, which is a new and dangerous piece developed by the Djvu/STOP family. This particular version started infecting computers in the second half of March 2023. Its recent activity has encrypted a lot of personal data with strong algorithms. Despite Tycx Ransomware has not being totally inspected just yet, there are some things that are clear already. For example, the virus reconfigures various types of data (images, documents, databases, etc.) changing original extensions to .tycx. This means that all types of data will save its initial name, but change the main extension to something like this "1.pdf.tycx". Once the encryption process gets to a close, you will no longer be able to access your data. In order to regain it, extortionists have scripted the creation of identical notes dropped into encrypted folders or onto a desktop. The name of the note is usually _readme.txt, which contains detailed instructions on how to recover your data.

Tywd Ransomware (the latest version of STOP or Djvu Ransomware) is extremely harmful and one of the most active encryption viruses. More than half of ransomware submissions to ID-Ransomware (ransomware identification service) are made by victims of STOP Ransomware. Although it has been in circulation for a couple of years, the number of infections caused by Tywd Ransomware continues to increase. It may be somewhat ironic, but most of the victims (at the moment) are users of pirated software. The version of the virus, that is under consideration today, adds .tywd extension to files. The malicious program also creates a text file (called _readme.txt) in each infected folder, which explains to the user that his computer is infected, and he will not be able to access his data until he pays a ransom of $980. If the user pays within 72 hours after infection, the ransom is reduced to 490 US dollars. The example of this ransom note is presented below.

Darj Ransomware is a prevalent encryption virus and blackmailer, that targets valuable personal files. Belongs to STOP/Djvu malware group. After infection and data encoding hackers start extorting the ransom. There have been more than 600 versions of the ransomware, each version gets slightly modified to circumvent the protection, but main footprints remain the same. The malware uses AES-256 in CFB mode. Shortly after launch, the STOP family cryptographer executable connects to C&C, retrieves the encryption key and infection ID for the victim's PC. Data is transmitted over simple HTTP in the form of JSON. If C&C is not available (the PC is not connected to the Internet, the server itself is not working), the cryptographer uses the hard-coded key and ID in it and performs offline encryption. In this case, you can decrypt the files without paying a ransom. Variations of STOP Ransomware can be distinguished from each other by ransom notes and extensions it adds to encrypted files. For STOP Ransomware under research today, extension is: .darj. The ransom note file _readme.txt is presented below in the text box and picture. In the article below we explain how to remove Darj Ransomware completely and ways to decrypt or restore .darj files.
