LLM-Driven Zero-Day Vulnerability Rapid Attack Framework Emerges, Exploit Window Shrinks from "Weeks" to "10 Minutes"

Hexstrike-AI represents a major breakthrough in attack AI. The framework builds an AI Orchestration Layer that seamlessly integrates large-scale language models such as Claude, GPT, etc. with 150+ professional network penetration tools (Nmap, Vulnerability Scanner, Code Generation, etc.) through the MCP (Model Context Protocol) agent. Attackers simply describe the target in natural language (e.g. "exploit NetScaler") and the framework automatically translates it into precise technical steps and executes them.

Critical attack chain: after Citrix publicized three zero-day vulnerabilities in NetScaler ADC on August 26, 2025, the framework's built-in automation capabilities allowed:

Automation of reconnaissance phase: Nmap performs large-scale IP scanning (thousands of IPs processed in parallel)

Vulnerability Confirmation Acceleration: AI Generates Targeted PoC Code, Fails to Automatically Retry Mutations

Leverage deployment in seconds: automate RCE code writing, webshell deployment, backdoor creation

Window collapse: compression from historical "weeks of development" to **"implementation in 10 minutes "**

Technical Risk: The framework removes the manual intervention bottleneck by exposing the tool interface through the FastMCP server. Even moderate attackers can perform complex operations through the simplified command interface.Citrix CVE-2025-7775 (uncertified RCE) has been exploited by Webshell in the wild, signaling that the tool is being deployed in the field.

Defense recommendation: Need to shift from "patch-based" to "threat hunting" and "real-time response", adopting Zero Trust architecture, API-level isolation, and automated vulnerability detection. The traditional weekly patch cycle is no longer feasible.
