Ransomware Red Flags: 7 Signs You're About to Get Hit

Caught off guard by a ransomware attack? Security experts say the warning signs were there all along.

Security Tools Are Being Used in Environments They Weren't Assigned To
Once attackers have admin rights, they will try to disable security software using applications created to assist with the forced removal of software, such as Process Hacker, IObit Uninstaller, GMER, and PC Hunter. These types of tools are legitimate, but if a specific tool is showing up on a system for which it's not assigned, then something is wrong. 
Any detection of Mimikatz (used in NotPetya) should get investigated, Sophos' Mackenzie adds. If no one on your security team confirms using it, that's a red flag because Mimikatz has become one of the most commonly used hacking tools for credential theft.

Backups no longer enough
Earlier, during a ransomware attack, organizations could remove the virus and restore files from the backup. The ransomware authors' tactics have now changed. They first steal all files that they can, and then encrypt everything. Later, if you don't want to pay the ransom, they threaten to publish your confidential files. In addition to backups, you need now to also take care of encrypting important info, both data at rest and data in transit.
