Your malware scan says everything is clean… but what if the attack never used a file in the first place?

In this episode of Cybersecurity 101, Mark Hemingway breaks down fileless malware — one of the stealthiest and most dangerous attack techniques used today. Unlike traditional threats, fileless malware runs in system memory, abuses trusted tools like PowerShell, and often leaves no trace on disk, making it incredibly hard for traditional defenses to detect.
You’ll learn:

What fileless malware actually is:

How attackers use legitimate system tools against you

Common techniques like memory injection and registry-based persistence

Why traditional antivirus often misses it

Practical steps to defend your environment

Modern attacks don’t always look like malware. Sometimes they look like normal system activity — and that’s what makes them so dangerous.
