Fileless malware is a powerful attack technique that has grown more in prominence because it is incredibly difficult to detect and can be cleverly hidden from security tools.
Fileless attacks are undetectable by most antivirus software, endpoint detection and response (EDR), and traditional security tools because these usually only discover compromises based on file descriptors in the file system. A fileless attack is executed from a memory address, making it almost impossible to collect evidence or forensic clues about what happened.
This paper explains the fileless malware attack and provides the cloud native security methods you can implement to discover and respond to these attacks.
