Chinese AI firms are siphoning capabilities from American models, CISA warns

CISA, NSA and FBI warn Chinese AI firms including DeepSeek and Moonshot AI extracted billions of tokens from US frontier models via distillation campaigns.

A joint CISA, NSA and FBI advisory says China-based firms including DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun and Z.AI have run industrial-scale knowledge distillation campaigns against US frontier models such as Claude, GPT, Gemini and Grok since at least late 2024, likely with Chinese government knowledge. The campaigns used gray-market API proxies called transfer stations, premium account pools and traffic routing to bypass restrictions, evade safeguards and exfiltrate billions of tokens used to train models like DeepSeek R1/V3 and Kimi. The agencies challenge DeepSeek's reported $5.6 million training cost and recommend identity verification, usage monitoring, response variation, differential privacy and indicator sharing as defenses.

CISA Warns Chinese AI Firms Extract Billions of Tokens From Claude, GPT, Gemini and Grok

CISA, NSA and FBI advisory says six Chinese AI firms extracted billions of tokens from Claude, GPT, Gemini and Grok via API proxies since late 2024.

A joint advisory from CISA, NSA and FBI alleges China-based AI companies including DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun and Z.AI harvested billions of tokens across millions of exchanges from Claude, GPT, Gemini and Grok variants since late 2024. Operators allegedly used API proxy 'transfer stations', account pools, bulk premium subscriptions and prompt injection or jailbreak-style requests to force models to reveal chain-of-thought reasoning. DeepSeek's R1 and V3 and Moonshot's Kimi-K2 and Kimi-K3 models reportedly benefited from the extracted data. CISA urged providers to add identity checks, monitor subscription-to-usage ratios, rate limit, and share infrastructure signals with cloud platforms.

DeepSeek, Alibaba and Chinese AI Firms Extract Billions of Tokens From U.S. AI Models

NSA, CISA and FBI advisory AA26-251A accuses DeepSeek, Alibaba and four other Chinese AI firms of industrial-scale distillation of US frontier models.

Joint advisory AA26-251A from NSA, CISA and FBI accuses DeepSeek, Alibaba, Moonshot AI, MiniMax, StepFun and Z.AI of extracting billions of tokens from Claude, GPT, Gemini and Grok variants since at least late 2024, likely with Chinese government awareness. Campaigns allegedly used API proxy 'transfer stations', account pools, metadata sanitization and prompt injection to harvest reasoning, coding, agentic and reinforcement-learning capabilities, with techniques mapped to MITRE ATLAS. DeepSeek's R1 and V3 and Alibaba's Qwen families reportedly trained on harvested outputs, and DeepSeek's $5.6 million training-cost claim is disputed as excluding distilled data value. Agencies urge anomaly monitoring, output alteration for suspected extractors, and intelligence sharing across vendors, clouds and aggregators.

Russian suspect in bank account takeovers is extradited to US

Russian web developer Sergei Filimonov was extradited from Georgia to the US to face charges in a multimillion-dollar bank account takeover fraud.

Sergei Anatolyevich Filimonov, 36, appeared in an Atlanta federal court on September 4 and pleaded not guilty to bank fraud, wire fraud, access device fraud, and aggravated identity theft charges. Prosecutors say that from November 2023 to October 2025 his group bought sponsored search-engine links that diverted online banking customers to spoofed login pages, stole their credentials, and initiated unauthorized wire transfers. The FBI linked the scheme to the December 2025 seizure of the domain web3adspanels.org, identifying at least 19 victims, roughly $14.6 million in confirmed losses, and about $28 million in attempted losses.

China-Based Artificial Intelligence Companies Conducting Industrial-Scale Distillation Campaigns Against U.S. AI Companies

NSA, CISA, and FBI warn DeepSeek, Alibaba, and other Chinese AI firms ran industrial-scale distillation of U.S. frontier models, threatening U.S. AI leadership.

A joint NSA, CISA, and FBI Cybersecurity Advisory (AA26-251A) says China-based firms DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun, and Z.AI extracted billions of tokens from U.S. frontier models including Claude, GPT, Gemini, and Grok, likely with Chinese government knowledge. Campaigns running since at least late 2024 used native APIs, cloud providers, third-party aggregators, gray-market proxy "transfer stations", and shared premium subscriptions to bypass geographic restrictions, evade safeguards, and violate providers' terms of use. The agencies recommend detecting anomalous prompts, accounts, and usage patterns; subtly altering responses to suspected distillers; and cross-organization intelligence sharing. They also call DeepSeek's publicly cited $5.6M training cost misleading because it excludes data acquired through distillation.

Srsly Risky Biz: Trump's Private Hacker Memo Is the Right Idea

A Trump presidential memo directs DHS to authorize vetted private-sector hackers to conduct cyber operations against foreign cybercriminal groups (CE-TCOs).

A presidential memorandum directs the Department of Homeland Security to establish a program authorizing private companies to conduct cyber surveillance and cyber effects operations against Cyber-Enabled Transnational Crime Organisations (CE-TCOs). Participating companies must pass vetting, obtain government approval before operations, and post a USD $1 million bond. The accompanying fact sheet cites more than USD $20.8 billion in US losses to cyber-enabled crime in 2025. Critics worry about accidental escalation if operations touch foreign government systems.

FBI: Hackers using social engineering to breach accounts and steal explicit content

FBI warns hackers use social engineering and password-stuffing to hijack social media accounts and sell victims' explicit content on criminal marketplaces.

The FBI issued an alert on threat actors who breach social media accounts of adults and children using password-stuffing with credentials from data leak sites, impersonation of social media support staff, and cloned login pages, in order to steal and sell explicit content. Stolen content is often posted with victims' personal information, leading to sextortion, harassment, and stalking. Related DOJ cases include a man who pleaded guilty to hacking about 600 Snapchat accounts and a former University of Michigan coach who accessed records of about 150,000 people across 100+ colleges.

Delta investigates in-flight Wi-Fi spoofing on post

A passenger on Delta flight 591 allegedly spoofed the airline's in-flight Wi-Fi with a rogue access point, prompting an FBI and FAA investigation.

Delta Airlines is investigating an incident on flight 591 from Las Vegas to Atlanta in which a passenger reportedly created a rogue Wi-Fi network named 'Delta WiFi Fast' to steal sensitive passenger data. The cabin crew deactivated the aircraft's Wi-Fi for roughly 30 minutes, and Delta says flight safety and aircraft operating systems were never affected. The FBI's Atlanta office and the FAA acknowledged awareness of the incident, which bears hallmarks of an evil twin attack involving spoofed login portals and credential harvesting. DEF CON organizers said this year's conference in Las Vegas also suffered multiple similar deauthentication Wi-Fi attacks.
