The best way to detect and defeat fileless malware attacks is to have a holistic approach with a multi-layered defense posture. An organization’s best practices for detecting fileless malware threats should include employing indicators of attack (IOAs) along with indicators of compromise (IOCs) and leveraging their security solution’s threat hunting capabilities.
Because fileless malware uses a system’s built-in tools to facilitate attacks and cover its tracks, cybersecurity teams must be aware, remain vigilant, and know the different methods attackers employ in carrying out these fileless malware attacks. It’s all about gaining visibility on cybercriminals that are trying hard to hide in a system’s memory.
