DETECTION OVERVIEW
Risk Factors
It is relatively easy for attackers to disguise a malicious file and share that file with a victim over common protocols such as HTTP, SMB/CIFS, or FTP. Changing the filename or extension of a malicious file does not affect the file hash, which is a unique signature that is calculated based on the contents of a file. A known malicious file hash that matches threat intelligence should be investigated to prevent the early stages of an attack such as ransomware.
The system might change the risk score for this detection.
