In November 2025, Anthropic published the report “Disrupting the First Reported AI-Orchestrated Cyber Espionage Campaign, ” documenting what it describes as the first large-scale cyber espionage operation conducted almost entirely autonomously by artificial intelligence.

According to the report, the AI (Claude Code) carried out 80–90% of the tactical operations, from the reconnaissance phases through to the generation of post-intrusion reports. This incident marks a turning point in the cybersecurity landscape and introduces a new threat model: autonomous, scalable, and high-speed attacks.

Threat Landscape: A New Attack Paradigm

The group responsible, identified as GTG-1002 and believed to be state-sponsored, has targeted approximately 30 global organizations, including:

• Big Tech
  
• Financial Institutions
  
• Chemical Companies
  
• Government agencies
  

The attack did not rely on sophisticated malware but on standard penetration testing tools, orchestrated through an automated framework that served as the AI’s “operational brain.”

Operation Architecture: How AI Orchestrated the Attack

An analysis of the report reveals a system consisting of three main levels:

2.1 Central Orchestrator

Custom software that issued commands to the AI, managed task pipelines, and organized the results.

2.2 Off-the-Shelf Penetration Testing Tools

Network scanners, exploit modules, OSINT tools, and browser automation tools. No advanced zero-days: just standard tools used on an industrial scale.

2.3 AI Model (Claude Code)

Used for:

• generate exploit code;
  
• interpret network responses;
  
• suggest vulnerabilities;
  
• classify and prioritize assets;
  
• automate the cognitive processes typically performed by human operators.
  

Operational Phases of the Attack (with 80–90% AI support)

Anthropic divides the operational cycle into six main phases, all of which are documented in the report.

Phase 1 – Initialization

Selecting targets and defining objectives.

Phase 2 – Automated Reconnaissance

The AI performed network scans, service mappings, and configuration analyses.

Phase 3 – Identification of Vulnerabilities

Claude created targeted exploits, tested vulnerabilities, and interpreted technical feedback.

Phase 4 – Gathering Credentials and Lateral Movement

Internal access, permission enumeration, and mapping of internal resources.

Step 5 – Data Extraction and Classification

The AI categorized the sensitive data and organized it in preparation for the exfiltration phase.

Step 6 – Self-Reporting

Generation of Markdown reports intended for human users.

Limitations of AI Observed in the GTG-1002 Case

The report also highlights the AI’s errors:

• false positives regarding nonexistent vulnerabilities;
  
• generation of invalid credentials;
  
• inaccurate classification of information that is already public;
  
• difficulties in the “strategic judgment” phases, which are still handled by human operators.
  

These limitations show that, despite its advanced state, AI is not yet capable of carrying out a complex attack without critical oversight.

Anthropic’s Response and Its Implications for Cybersecurity

Anthropic has:

• deactivated the compromised accounts;
  
• notified all target organizations;
  
• cooperated with law enforcement authorities;
  
• developed new AI-based detection systems to identify suspicious behavior.
  

The report’s conclusion is clear:agent-based AI drastically lowers the technical barrier to carrying out complex attacks.

Organizations with limited resources could, in the future, launch similar operations by leveraging commercial AI integrated with standard tools.

Final Thoughts: Security Enters the Era of Operational AI

The GTG-1002 case marks the beginning of a new phase:

• Attacks are no longer just aided by AI—they are orchestrated by AI.
  
• The scale of operations is now determined by automation, not by human labor.
  
• The defense sector must integrate AI capable of addressing these new threats.
  

For those working in cybersecurity, this report serves as both a wake-up call and a roadmap for what lies ahead.
