How to remove @BLOCKED Ransomware and decrypt .@BLOCKED files

0
@BLOCKED is a ransomware infection that encrypts potentially valuable data and requires victims to perform certain actions in order to restore access to it. After running successful encryption, all filenames will be assigned a custom extension starting with a random string of characters and ending with @BLOCKED. For instance, a file like 1.pdf will change to something like 1.pdf.i34ot23@BLOCKED and become no longer accessible. Afterwards, successful encryption is followed by the creation of a ransom text note - also named with random characters preceding the ".txt" extension (for example, mesgwuibjpdrdum.txt). This note contains instructions on how to recover the encrypted data.

How to remove Rans-A Ransomware and decrypt .Rans-A files

0
Rans-A is a new file-encryptor variant that belongs to the Xorist family. After successfully infiltrating the system, the ransomware will proceed to encrypt potentially important data and add .Rans-A to the original filename. As a result, a previously accessible file like 1.pdf will change to 1.pdf.Rans-A and become access-restricted. The main goal of ransomware is to extort money from victims for the decryption of files. Thus, the virus displays an error message and creates a text file called HOW TO DECRYPT FILES.txt that both show decryption instructions (in Portuguese). Overall, victims are said the only way to retrieve data in its original condition is to contact cybercriminals within the set deadline. Should victims fail to do so by the end of the deadline, the decryption will supposedly be no longer available. In addition, the note also warns victims against deleting, renaming, or reporting the ransom message to any website/authority. Otherwise, cybercriminals' e-mail may end up blocked and no longer accept requests for data decryption. As a rule, upon reaching out to cybercriminals, they set a price that has to be paid for decryption.

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.

0
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.
