Just picked up a laptop from someone who got hit by ransomware encryption. I'm familiar with cryptowall and some the traces it leaves behind but this seems to be a little new. There isn't any html pages that open with images other than the text below. It doesn't really state what ransomware that they got.. All of their file extensions got changed to a .abc files extension (ex: "Test.docx.abc"). I've tried correcting the file extensions but when opening in the proper programs it says the files are corrupted. Also in all folder locations it has put the decryption files "restore_files_rvrk.txt" and "restore_files_rvrk.html" which just say the text below (I took out the web addresses it listed at the end). They do not have any system restore points and none of the files can be restored to a previous version so I am probably just going to do a rebuild on the laptop but I was curious to see what you guys thought.
What happened to your files ?
All of your files were protected by a strong encryption with RSA-2048.
What does this mean ?
This means that the structure and data within your files have been irrevocably changed, you will not be able to work with them, read them or see them,
it is the same thing as losing them forever, but with our help, you can restore them.
How did this happen ?
Especially for you, on our server was generated the secret key pair RSA-2048 - public and private.
All your files were encrypted with the public key, which has been transferred to your computer via the Internet.
Decrypting of your files is only possible with the help of the private key and decrypt program, which is on our secret server.
What do I do ?
Alas, if you do not take the necessary measures for the specified time then the conditions for obtaining the private key will be changed.
If you really value your data, then we suggest you do not waste valuable time searching for other solutions because they do not exist.
