Is .YDHM files virus on the rise again? Is YDHM part of Matrix ransomware? Can files encrypted by YDHM be recovered?
YDHM is a brand new version of the Matrix ransomware. It is dubbed this way by malware researchers, because it is appending the .YDHM extension to files after their encryption. Files are locked with both of the AES 128-bit and RSA 2048-bit military grade encryption algorithms. When the encryption process is over, the .YDHM files virus will place a ransom note message with instructions inside a file called “!YDHM_INFO!.rtf“. The YDHM cryptovirus is part of the Matrix ransomware family and it will demand money as a ransom to allegedly get your files recovered. Continue to read through the article to see how you could try to potentially restore some of your files.
