In 2025, zero-trust architectures (ZTAs) are revolutionizing network defense, but they’re not impenetrable. My latest blog dives into advanced pentesting strategies, drawing from recent breaches like the ToolShell chain in Microsoft SharePoint (CVEs 2025-49704, -49706, -53770, -53771) and Ivanti exploits by UNC5221. Learn step-by-step methodologies: from asset mapping with BloodHound and Nmap, to authentication bypasses, segmentation probes using Scapy, and post-exploitation with Covenant. Key insights include avoiding policy drift, leveraging OWASP for microservices, and purple teaming for fixes. Backed by CISA, NIST, and real-world trends, this guide equips pentesters to emulate adversaries effectively. What’s your toughest ZTA challenge?
