Your EDR says “no malware detected.” Should you be relieved?
Not necessarily.
CrowdStrike's 2026 Global Threat Report found that 82% of detections in 2025 were malware-free. It also reported an 89% increase in attacks by AI-enabled adversaries.
This tells us something important about modern intrusions.
Attackers don't always need to bring their own tools.
They can abuse:
→ Valid credentials
→ PowerShell
→ Remote administration tools
→ Cloud services
→ Existing system utilities
→ Legitimate APIs
→ Compromised accounts
Everything can look legitimate.
That's what makes these attacks difficult.
The question for defenders therefore shouldn't simply be:
“Is this file malicious?”
It should be:
“Is this behavior normal?”
A legitimate tool used by the wrong account at the wrong time against the wrong system can become a security incident.
This is why behavioral analytics, identity telemetry, endpoint visibility and good detection engineering matter so much.
Malware detection is important.
But modern security needs to detect malicious intent expressed through legitimate capabilities.
The attacker doesn't always need to install something.
Sometimes they just need to use what you already have.
