Detection Engineering & Incident Response: CVE-2026-2329
Respond to an unauthenticated-RCE compromise of a Grandstream IP phone (CVE-2026-2329). Reconstruct the timeline from web and device logs, find the attacker's rogue provisioning persistence, engineer and tune a detection rule for the overflow pattern, then contain, eradicate (firmware + config), verify and report.
