CrowdStrike Threat Intelligence and OverWatch observed that in H1 2026, 91% of vulnerabilities with publicly available proof-of-concept (PoC) code were weaponized and exploited within 48 hours, with the fastest recorded exploitation occurring 35 minutes after PoC publication. Adversaries integrated large language models (LLMs) into exploit development, automating vulnerability analysis, payload generation, and initial access. Technical artifacts include public PoC repositories, LLM-generated exploit scripts, automated scanning frameworks, C2 infrastructure, and AI-assisted reverse engineering tools. Defenders face a collapsed remediation window requiring accelerated patching and C2 detection.
