Subject: [Intel] AI-Driven Attack Campaign using ARTEX Framework

Dear Team,

We are sharing intelligence regarding a high-speed attack campaign by the China-backed threat group Vapor Panda.

■ Overview
Vapor Panda is utilizing ARTEX, an automated agentic AI penetration testing framework integrated with DeepSeek. This allows the actor to pursue multiple attack paths concurrently with extreme speed (requests every 10 seconds), resulting in the compromise of ~140 sensitive targets within 11 days.

■ Scope
- Government agencies, Defense, Intelligence, and critical sectors (Semiconductors, Pharma, Finance, Telecom).

■ Recommended Actions
1. Monitor logs for high-frequency reconnaissance patterns and anomalous authentication attempts on external-facing assets.
2. Enforce and audit Multi-Factor Authentication (MFA) for all privileged accounts.
3. Increase the frequency of vulnerability scanning and accelerate patching for perimeter devices.

■ Reference
- CrowdStrike Threat Report

Priority: High
Deadline: Immediate review
