How to use Trend Micro Ransomware File Decryptor
In the first step, the user has to choose the ransomware name. The selection looks as follows:
In case you don’t know the ransomware name, you can click on “I don’t know the ransomware name” option. The tool will prompt the user to select a target file to be decrypted. The tool tries to automatically identify the ransomware-based on the file signature.
In the second step, you need to select the file or folder on your PC to perform the decryption process. The tool can either attempt to decrypt a single file or all files in a folder and its sub-folders by using recursive mode. By clicking “Select & Decrypt”, choose a folder or a file and click OK to start the decrypting process.
In further steps, the Trend Micro Ransomware File Decryptor starts decrypting the files based on their file extension names. In the case of some ransomware file extensions, the tool may ask you to provide additional information about the files. At some times, you will be provided with two files; one infected file and second, matching non-infected file if there is an available backup copy. At this stage, you can select which file to be processed. Ideally, larger sized file should be selected; which clearly means it consists of more data.
Once the scan and decryption process is finished, the UI will show the results. The results include details such as duration of the scan, the number of infected files and number of decrypted files. At this stage, you can see the encrypted files’ location. The fixed file will have the same name of the original file with “_fixed” appended to the file name and will be placed in the same location.
Limitations of the decryptor tool
Though the tool is efficient enough to identify various ransomware file types and decrypts them; it may not be able to do it completely every time. This is applicable specifically to the files affected by CryptXXX V3 ransomware. For the files which are decrypted partially by the tool, users are suggested to use 3rd party recovery tools.
The creators of the tool have mentioned its limitation about the CERBER decryption as well. According to the creators of the tool, CERBER decryption must be executed on the infected machine itself (as opposed to another machine). This is because the tool needs to try and locate the first infected file for a critical decryption calculation. Further, due to the method of decryption for CERBER, the Ransomware File Decryptor may take several hours (average is 4) to complete decryption on a standard Intel i5 dual-core machine.
