A virus, belonging to the HiddenTear project, named Rush has continued to infect user PCs, adding the .crashed file extension after it encrypts their files. The virus is almost identical with Sanction ransomware with differences being the name, encryption and file extensions used.

Security experts strongly advise against making any ransom payoff to the developers of this virus since this may not result in getting your files back and furthermore, you support the cyber-criminals.
