I recently came across a discussion about fileless malware, and now I’m confused. A few people claimed it’s easier to detect because it doesn’t create files, but I’ve also seen the opposite. How does the detection of fileless malware really work compared to normal, file-based malware?
Fileless malware is not as easy to detect-it’s actually tougher for security tools to pick up. The main difficulty is that it runs directly in a system’s memory instead of creating files on the hard drive. It is not easy for antivirus tools to scan file activity, and most of the usual signature-based detection methods don’t work.
In comparison to fileless malware, Traditional malware is much more easy to identify because it leaves behind files or artifacts that security software can analyze. Fileless attacks, on the other hand, live in memory and often rely on trusted tools like PowerShell or WMI, which makes their behavior blend in with normal system operations.
Because of this, spotting fileless threats usually requires more advanced techniques like behavior monitoring and memory forensics rather than standard antivirus scanning.

From what I’ve seen, traditional malware is still much easier to spot because it leaves actual files behind, and most security tools are designed to scan exactly that. Fileless malware ends up being a different story. Since it runs straight from memory and uses built-in components like PowerShell or WMI, it blends in with normal system activity and doesn’t leave much for typical antivirus tools to examine.
You generally need something that watches behaviour rather than just looking for known files. I’ve noticed this while working with CYBERSICS-it’s the behavioural patterns and memory activity that tend to reveal something is off, not file signatures. That approach usually gives you a clearer picture of what’s happening behind the scenes, especially with threats that never touch the disk.
So compared to regular, file-based malware, detecting fileless attacks really does require a different, more advanced method.
