AI Is Giving Lesser-Resourced Attackers Nation-State-Level Reach, Google Warns
Google's Threat Intelligence Group warns AI now gives lesser-resourced criminal and nation-state attackers nation-state-level speed and scale, citing TeamPCP, Basin Castle, APT42, and APT24 usage.
GTIG documented throughout 2026 that adversaries increasingly use AI to automate and scale attacks. TeamPCP (UNC6780) used an AI coding chatbot with agent instructions to plan and execute a mass credential harvesting campaign in under six hours, and has compromised PyPI, npm, and Docker Hub since March 2026 with its Dustmaker credential stealer plus released tools Shai-Hulud and Miasma. PRC-nexus Basin Castle uses LLMs for target profiling, lure drafting, and malware development; APT42 (Calanque Ion) uses Gemini for OSINT and localized lures; APT24 (Ravine Castle) uses Gemini across the full attack lifecycle; and DPRK's Midnight Neptune (UNC1069) integrates AI into cryptocurrency theft. Google responds by disrupting attacker accounts and hardening models against distillation attacks.

NSA, FBI warns of hackers using AI-generated tools in attacks on critical infrastructure technology
NSA and FBI warn of an active campaign using AI-generated exploit scripts against Siemens S7 PLCs in critical infrastructure sectors.
NSA, FBI and other federal agencies issued an urgent advisory describing an active threat campaign targeting US-based Siemens S7 Series PLCs with AI-generated exploitation scripts disguised as legitimate monitoring tools. Actors use internet scanning to find exposed PLCs in energy, water, and manufacturing sectors, and may be preparing for operational effects. The advisory expands on July warnings of Iran-affiliated hackers targeting PLCs from Siemens, Schneider Electric, Rockwell Automation, and Allen-Bradley.

Anthropic Says Russian Hackers Used Claude AI to Automate Malware Evasion
Anthropic disrupted Midnight Blizzard campaigns where AI agents automatically rebuilt malware to evade detection, targeting 20+ government and defense organizations.
Anthropic's threat intelligence report documents the Russian state-nexus actor Midnight Blizzard using Claude to automatically monitor, modify, and redeploy malware until it evaded security products. The campaign hit more than 20 organizations, including Ukrainian and European government ministries, defense bodies, embassies, and think tanks, with mailbox theft from two drone component manufacturers and compromise of hotel guest Wi-Fi via DNS hijacking. The report also describes financially motivated groups GTG-50020 and GTG-50021 targeting AI credentials, including a prompt-injection attack on an automated evaluation sandbox that yielded production API keys and attempts to reach a pre-release Claude model across roughly 30 AI companies.

Threat actors are coming for your AI assets to operationalize their use of AI
Google GTIG reports espionage and crime groups stealing AI models, prompts, and API credentials, plus distillation campaigns and agentic AI attack automation.
Google Threat Intelligence Group's quarterly AI Threat Tracker reports adversaries stealing proprietary models, source code, prompts, and API credentials from government, healthcare, and media targets, including China-based UNC6508 compromising clouds to run unauthorized LLM workloads. Distillation campaigns against Google's models exceeded 100 million prompts launched via thousands of stolen account credentials through proxy networks. Mandiant also observed a financially motivated actor deploy an autonomous multi-agent framework that harvested thousands of third-party credentials in under 6 hours, and a 'Recon' framework on a live C2 server managing over 23,000 stolen credentials including cloud and AI API keys.

Chinese Hackers Use AI Agents in Multi
China-linked campaign used the SecFlow AI-agent framework (Claude, Qwen, DeepSeek) to automate intrusions against government targets in Taiwan, Indonesia, China and Vietnam.
Hunt.io documented a second China-linked campaign wiring commercial AI models into live cyberespionage, reconstructing the SecFlow orchestration system from five accidentally exposed open directories. Targets included Taiwan's Kuomintang Party archives, Indonesia's Ministry of Foreign Affairs, mainland Chinese government and education systems, and Vietnamese industrial hosts. The most extensive compromise hit a Fengtai District government Office Automation environment, yielding LSASS and registry hive theft, 822 user records and 1.28GB of attachments including patient health data. Tooling included a GLUTTON webshell hiding payloads in PNG pixels via steganography and a fake MySQL deserialization service for client-side code execution.
