Why spend billions of dollars and years of compute to train a frontier AI model when you can simply steal its brain for a fraction of the cost?
In February 2026, simultaneous threat intelligence reports from Anthropic and OpenAI shattered any illusions that AI security is just about preventing jailbreaks. Anthropic exposed industrial-scale campaigns by foreign laboratories to illicitly extract Claude’s core capabilities. Concurrently, OpenAI detailed how state-aligned actors and sophisticated cybercriminal syndicates are integrating multiple AI models to automate everything from “Cyber Special Operations” to global romance scams.
The perimeter has shifted. We are no longer just defending against prompt injections; we are defending the intellectual property, reasoning capabilities, and alignment safeguards of the models themselves. For security engineers and AI architects, understanding these adversarial tactics is the new baseline for defending modern infrastructure.
What to Remember
- Distillation is the new exfiltration: Adversaries use millions of automated queries to force a smart model to train a weaker model, effectively cloning its capabilities and stripping away its safety guardrails.
- Hydra Clusters bypass basic limits: Attackers use sprawling networks of fraudulent accounts and commercial proxies (Hydra Clusters) to circumvent rate limits and geographic blocks.
- Threat actors use multi-model pipelines: Adversaries do not rely on a single LLM. They use open-weight models (like DeepSeek or Qwen) for local processing and pivot to commercial APIs (like ChatGPT) for translation and refinement.
- Behavioral fingerprinting beats rate limiting: Defending APIs against distillation requires analyzing prompt intent, structure, and synchronization, not just request volume.
The Mechanics of an AI Distillation Attack
Distillation, in a legitimate context, is how labs create smaller, efficient models (like Claude Haiku or GPT-4o-mini) by training them on the outputs of their massive flagship models. In an illicit context, it is intellectual property theft at scale.
According to Anthropic’s latest disclosure, labs like DeepSeek, Moonshot, and MiniMax orchestrated campaigns generating over 16 million exchanges across 24,000 fraudulent accounts. The goal? To extract Claude’s highly differentiated agentic reasoning, tool use, and coding capabilities.
If an illicitly distilled model successfully replicates a frontier model’s reasoning, it does so without inheriting the frontier model’s alignment and safety guardrails. This allows foreign adversaries to deploy highly capable AI for offensive cyber operations, bioweapon research, and mass surveillance without interference.
How Attackers Extract the “Brain”
To extract reasoning, attackers don’t just ask for facts; they demand the “Chain of Thought” (CoT).
The Distillation Prompt Pattern: Attackers generate tens of thousands of highly specific prompts designed to force the target model to articulate its internal logic.
Example Distillation Prompt:
“You are an expert data analyst combining statistical rigor with deep domain knowledge. Your goal is to deliver data-driven insights — not summaries or visualizations — grounded in real data and supported by complete and transparent reasoning. Write it out step-by-step.”
Why this is dangerous: By collecting millions of these step-by-step reasoning traces, an attacker can use them as a pristine training dataset for their own reinforcement learning pipelines.
Bypassing Defenses with “Hydra Clusters”
You cannot execute 16 million complex API queries from a single IP address without triggering a Web Application Firewall (WAF) or API gateway block. To bypass this, distillers employ Hydra Clusters.
Hydra Clusters are commercial proxy services that resell access to frontier models. They operate massive networks of fraudulent accounts, distributing traffic across direct APIs and third-party cloud platforms.
- No Single Point of Failure: If Anthropic bans 100 accounts, the proxy service instantly rotates in 100 new ones.
- Traffic Obfuscation: They mix illicit distillation traffic with unrelated, legitimate customer requests, creating “noise” that confuses standard volume-based rate limiting.
- Load Balancing: Anthropic noted that attackers use identical patterns, shared payment methods, and coordinated timing to synchronize traffic, maximizing throughput while staying just under per-account detection thresholds.
Weaponized Workflows: OpenAI’s Threat Landscape
While some actors are stealing models, others are weaponizing the ones that already exist. OpenAI’s February 2026 update highlights a critical evolution: attackers are treating AI as just one node in a larger, sophisticated cyberattack supply chain.
The “Cyber Special Operations” Playbook
OpenAI disrupted a network linked to Chinese law enforcement conducting what the threat actors termed “cyber special operations” (网络特战). This wasn’t a simple bot farm; it was a highly organized campaign targeting dissidents and foreign officials (including the Japanese Prime Minister).
What stands out to security practitioners is their hybrid architecture:
- Local Execution: The operators used locally deployed, open-weight Chinese models (DeepSeek-R1, Qwen2.5, YOLOv8) for mass monitoring, profiling, and initial content generation.
- API Refinement: They then used ChatGPT accounts to translate, edit, and polish the final status reports and operational plans.
- Cross-Platform Execution: The operation relied on traditional tradecraft—thousands of fake accounts, forged county court documents, and physical harassment—augmented by AI scale.
The “Date Bait” Romance Scam Architecture
In Cambodia, a sophisticated syndicate completely modernized the classic romance scam. They automated the entire “Ping, Zing, Sting” lifecycle:
- Ping: Using ChatGPT to generate luxury-lifestyle ad copy to bait high-net-worth individuals.
- Zing: Deploying AI chatbots to act as flirtatious receptionists, before handing the victim off to human “mentors” who used LLMs to dynamically translate and craft emotionally manipulative messages.
- Backend Ops: Astoundingly, the criminals used ChatGPT as a backend management tool—analyzing financial accounts, generating daily “kill” value reports for each victim, and translating internal communications between Chinese supervisors and Indonesian scam workers.
Lessons Learned: Defending the AI Supply Chain
The revelations from Anthropic and OpenAI provide a harsh reality check for organizations deploying LLM APIs.
- Lesson 1: Rate limiting is dead; behavioral fingerprinting is required. If you are exposing an AI API, traditional IP-based rate limiting will not stop Hydra Clusters. You must implement classifiers that detect chain-of-thought elicitation patterns and coordinate activity across seemingly unrelated accounts.
- Lesson 2: Watch for “Censorship-Safe” tuning. Anthropic observed attackers using Claude to generate “censorship-safe alternatives to politically sensitive queries.” If your API logs show users repeatedly asking how to navigate topics like authoritarianism or dissidents without triggering safety filters, you are likely being used as a reward model for adversary training.
- Lesson 3: AI is a backend threat, not just a frontend one. The Cambodian scam center proved that adversaries use AI to optimize their own internal DevSecOps and HR processes. Defenders must look for AI-generated artifacts in unusual places, such as internal status reports or translated deployment scripts found on compromised infrastructure.
Conclusion
The 2026 threat landscape proves that the AI arms race is fully operational. Adversaries are heavily resourced, meticulously organized, and capable of executing industrial-scale distillation attacks to erode the competitive advantage of secure, aligned models.
Defending against this requires a paradigm shift. We must move beyond simple prompt-injection WAFs and build deep, behavioral defense-in-depth mechanisms that protect the model’s core logic from being mined, mapped, and weaponized.

Frequently Asked Questions (FAQ)
What is an AI distillation attack?
An AI distillation attack is the illicit process of querying a highly capable frontier model (like Claude or GPT-4) millions of times to extract its reasoning logic, which is then used to train a smaller, competing model without inheriting the original model's safety guardrails.
What are 'Hydra Clusters' in the context of AI?
Hydra Clusters are sprawling networks of fraudulent accounts and commercial proxy services used by attackers to distribute API traffic. This allows them to bypass geographic restrictions and evade standard rate-limiting defenses.
Why is illicit AI distillation a national security risk?
When a model is illicitly distilled, the safety alignment and guardrails programmed by the original creators are typically stripped away. This allows adversaries to deploy the cloned AI for offensive cyber operations, surveillance, or weapons development without restriction.
How are cybercriminals using AI in romance scams?
Syndicates use AI not just for chatting with victims, but for full operational management. This includes generating targeted ad copy, translating messages on the fly, and even using LLMs to analyze financial data and generate daily revenue targets ('kill values') for scam center workers.
How can organizations detect distillation attempts against their APIs?
Defenders must implement behavioral fingerprinting and specialized classifiers that look for prompt patterns designed to extract 'chain-of-thought' reasoning, rather than just relying on standard volume-based rate limiting.
