Verify AI Security Tools and Test Incident Response Plans for 2026
Huntress research outlines shifting endpoint risks, including multi-layered ransomware tactics and the need for human oversight in AI-driven defenses.
Key points
- Ransomware groups are using multi-layered extortion tactics that combine data theft with encryption and public pressure.
- Only 55% of companies have fully documented incident response plans, and just 30% regularly test them.
- AI-powered security agents require human oversight to prevent unpredictable behavior and ensure accurate threat detection.
Huntress research identifies evolving endpoint security challenges for 2026, emphasizing the need for human-led oversight and tested incident response plans to counter sophisticated threats.
In plain English
Endpoint security is changing because traditional antivirus software cannot stop modern attacks that blend endpoints, identities, and cloud workloads. Threat actors now use living-off-the-land techniques to hide within normal system processes. This makes detection harder for automated tools alone. Organizations must move beyond perimeter defenses to monitor internal activities closely.
The background
Ransomware tactics are becoming more aggressive, with groups employing double or triple extortion methods. According to Huntress, attackers now harvest credentials and threaten data disclosure before encrypting files. This multi-front approach increases business risk and public fallout. Fast detection is essential to stop these incidents from causing downtime or exposing sensitive information.
What changes now
AI is becoming more embedded in security operations, but it introduces new risks. Agentic AI tools can analyze large data volumes but may behave unpredictably if attacked or misused. Huntress notes that AI works best with human oversight. Security teams should ensure AI systems are intentional and controlled, pairing automated detections with human analysts who validate suspicious activity before it becomes a breach.
Key terms explained
Endpoint security protects devices like laptops and servers from threats. Incident response involves planned steps to handle breaches, including communication and cleanup. Extended detection and response combines signals from various sources, such as email and cloud workloads, to improve visibility. Teams usually check whether their plans cover common scenarios like ransomware and suspicious remote access.
Background: Extended detection and response (XDR)
Extended detection and response (XDR) aggregates telemetry from endpoints, networks, and cloud workloads into a single engine. It uses this unified view to correlate weak signals across sources, identifying complex attacks that isolated tools ignore. You gain better visibility but accept higher infrastructure costs and tuning complexity.

What to do and how to stay safe: Huntress
- Review your incident response plan to ensure it is fully documented and includes playbooks for common scenarios.
- Verify that your security tools include human oversight for AI-driven detections to prevent false positives or misses.
- Check for signs of credential harvesting and data exfiltration, as these often precede ransomware encryption.
- Monitor endpoint activities for living-off-the-land techniques that blend with normal system processes.

Frequently asked questions
How many companies have tested incident response plans?
According to IBM’s Cost of a Data Breach Report 2025, just 30% of companies regularly test their incident response plans.
What is multi-layered extortion in ransomware attacks?
Multi-layered extortion combines data theft, file encryption, and public pressure to force higher payouts from victims.
Why is human oversight important for AI security tools?
AI agents can miss novel threats or behave unpredictably if attacked, so human analysts are needed to validate suspicious activity.
