Fileless Malware
Most malware installs files on your computer that antivirus can find. Fileless malware is sneakier - it lives only in your computer's memory and uses built-in Windows tools to do bad things. When you restart, it's gone from memory, but it often finds ways to come back.
What is Fileless Malware?
Malware that operates entirely in memory without writing files to disk, using legitimate system tools and processes to carry out malicious activities while evading traditional antivirus detection.
Why Should You Care?
Understanding fileless malware is essential for building a strong security posture. This knowledge helps organizations identify threats early and respond appropriately.
