Pentesters

Open-source “AI hacker” tools automate red-team workflows but can silently exfiltrate pentest output to third-party LLM APIs—exposing IP, credentials, and regulated data. This post explains the real risk (data egress, not training), why traditional DLP/SIEM often misses it, and how enterprise-safe approaches—like isolated, auditable platforms—prevent unauthorized leakage.

Awareness doesn’t equal defense. Threat Actor Intelligence helps you go beyond the headline: “Are these attackers using techniques that would actually work in our environment?”

Pentesters and red teams share a common goal: improving an organization’s security posture. But their objectives, scope, and methods differ. NodeZero® helps both teams succeed by showing what’s truly exploitable, so you can cut through the noise and continuously validate your security posture.

Scanning and patching aren't enough. Learn the critical difference between being vulnerable and being exploitable—and why it's the key to preventing real-world breaches.

Critical Ivanti Endpoint Manager vulnerabilities revealed—learn about CVE exploits and mitigation.

Introduction The recent VMware VMSA describes four new CVEs affecting VMware vRealize Log Insight, reported by ZDI. Three of these CVEs can be combined to give an attacker remote code execution as root. This vulnerability is exploitable in the default configuration for VMware vRealize Log Insight. We have successfully reproduced this exploit and would like…
