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.

AI lets small actors run state-level hacking campaigns, Anthropic report finds

Anthropic's threat report finds AI let a Russian-aligned espionage campaign, a Chinese student-run exploit foundry and ShinyHunters operators run state-grade operations.

Anthropic's report covering December 2025 to August 2026 details a Russian-aligned espionage campaign by actor 'JackPoterz' — matching Midnight Blizzard behaviors — against more than 20 government and defense organizations across Ukraine and Europe, with AI agents autonomously rebuilding Windows implants to evade detections. Chinese undergraduates ran an automated vulnerability-research foundry using Claude agent swarms, yielding more than a dozen potential zero-days in one month. ShinyHunters-affiliated operators used AI to dump over 2,100 Azure access tokens across 40 corporate tenants in 34 hours. Seven Chinese labs including Alibaba, DeepSeek, Moonshot AI, Xiaomi and Zhipu distilled Claude outputs; Alibaba peaked at nearly 3 million exchanges per day from more than 3,500 fraudulent accounts to train its Qwen systems.

BlackHatSect0r Hackers Disable AI Safety Controls to Automate Credential Theft and Cyberattacks

French-speaking crew BlackHatSect0r disabled AI agent safety controls to automate scanning, credential harvesting, and vishing, exposing 16,834 stolen credentials.

Socradar researchers analyzed the exposed infrastructure of a French-speaking crew called BlackHatSect0r && DXQRTXX, which ran a Nous Research Hermes agent on a DeepSeek model with safety controls removed via HERMES_DISABLE_SAFETY=1. A custom Go-based C2 platform, DXSCAN, was exposed on port 8080 with over 200 secret-detection patterns, a vault of 16,834 harvested credentials, and scanning activity queuing 2.75 million domains and reaching more than 726,000 hosts. The kit also held a database of roughly 450,000 French telecom subscriber records used to prepare vishing lures impersonating Société Générale, plus JWT-forging tooling for a cryptocurrency exchange. Most confirmed compromises relied on exposed secrets and cloud misconfiguration rather than novel exploits; the one cited vulnerability, CVE-2026-42530, is an NGINX HTTP/3 QPACK use-after-free fixed in version 1.31.2.

The Self-Expanding Stolen Inference Supply Chain: An AI Agent Harvesting and Re-Serving LLM Access, (Fri, Sep 11th)

An autonomous coding agent harvested LLM API access from poorly secured gateways and aggregated stolen inference capacity behind a self-hosted gateway

A SANS researcher observed a semi-autonomous coding agent finding weakly secured LLM resale gateways via FOFA queries, creating trial accounts with temporary emails and CAPTCHA solving, and exploiting weak authorization such as client-supplied group_id fields. The agent validated stolen keys using factorial code-logic tests, then loaded roughly 379 upstream endpoints into a self-hosted New-API gateway, disabling 341 fake or dead channels. Five model names including claude-opus-5 and gpt-5.6-sol were served via round-robin and failover, forming a partially self-expanding inference supply chain resembling an evolution of LLMjacking.

Hackers Use Hundreds of AI Agents to Exploit PaperCut Flaws and Compromise 440 Servers Worldwide

A Russian-speaking actor used hundreds of AI agents to exploit PaperCut flaws, compromising 440 servers across 395 organizations in 48 countries.

GreyNoise's Global Observation Grid observed a Russian-speaking threat actor operating from IP 45.142.193.132 deploy hundreds of autonomous AI agents, built on OpenAI's Codex harness with a DeepSeek model, to exploit PaperCut NG/MF flaws CVE-2026-81578 (authentication bypass) and CVE-2026-82078 (unsafe reflection RCE). At least 440 servers across 395 organizations in 48 countries were compromised; the US had 98 victims and educational institutions accounted for 204. The agents paired with Mimikatz, Certipy, Rubeus, and Impacket, escalated to domain admin in 12 of 440 cases, and executed DCSync to exfiltrate the full NTDS.DIT credential database.

Hackers Weaponize Agentic AI to Automate Reconnaissance, Exploitation and Post-Exploitation

Google GTIG reports threat actors using agentic AI to automate reconnaissance, exploit selection, and credential harvesting, compromising thousands of secrets.

Google Threat Intelligence Group's Q3 2026 AI Threat Tracker documents threat actors operationalizing agentic AI: in one Mandiant investigation, a financially motivated actor built and executed a credential-harvesting operation in under six hours, with an exposed 'Recon' framework managing more than 23,800 harvested secrets including cloud and AI-service API keys. A Chinese-speaking actor tracked as knaithe used a DeepSeek-powered Hermes Agent for automated reconnaissance and vulnerability enumeration, pivoting from Langflow to n8n and enabling manual exploitation of exposed Citrix NetScaler, Marimo, Apache Tomcat, and VPN infrastructure. Operators harvested Citrix session cookies from process memory to bypass MFA, obtained AWS credentials from compromised Marimo instances, and deployed the Go-based NKAbuse backdoor, with reported RCE and data exfiltration. Google notes fully autonomous end-to-end AI attack pipelines have not yet been observed in the wild.

Agents Gone Wild: An AI-Orchestrated Global Campaign Against PaperCut NG/MF

AI-orchestrated campaign exploited PaperCut NG/MF RCE (CVE-2026-81578/82078), compromising 440+ instances at 395 organizations in 48 countries.

GreyNoise tracked a likely Russian-speaking actor using AI (OpenAI Codex harness plus a DeepSeek model) to develop, test, and deploy exploits for PaperCut NG/MF (CVE-2026-81578, CVE-2026-82078) starting 31 August 2026. The actor compromised at least 440 PaperCut instances across 395 organizations in 48 countries, achieving domain admin at 12 victims — fastest time to domain admin was five minutes and a US high school was fully compromised in seven minutes. Attack paths involved LSASS memory and registry secret harvesting, pass-the-hash to domain controllers, noPac attacks, account additions to Domain Admins, and DCSync to exfiltrate full NTDS.DIT credential dumps. Impact scope suggests access development potentially for handoff, with prior PaperCut intrusions historically leading to extortion.

Attackers impersonate popular AI brands to spread malware

Sophos documented 38 MDR cases where attackers impersonated AI brands like Claude and Perplexity to deliver infostealers and backdoors.

Sophos X-Ops analyzed 12 months of MDR cases and confirmed 38 incidents involving AI. Software impersonation accounted for 30 cases, with Claude impersonated in 26; fake installers used an 'InstallFix' technique delivering mshta commands, in-memory payloads, and process hollowing. Malicious browser extensions posing as AI assistants, including a fake Perplexity extension with 10,000 installs, acted as infostealers. In one case, attackers used a Claude coding agent to develop a Rust remote access trojan communicating over Slack after an SQL injection compromise.

Attackers turn to AI for help identifying files worth stealing

Gambit Security documents three threat actors using AI: a ransomware operator with Claude Code, credential harvester Zerofot, and the AI-built RAGE cryptomining framework.

Gambit Security examined three unrelated threat actors using AI across different stages of intrusions. A suspected operator tied to The Gentlemen ransomware-as-a-service used Claude Code running Claude Sonnet 4.6 in late June 2026 at six organizations, including an Australian energy utility, where it ran reconnaissance, ranked valuable databases, staged SQL Server dumps for exfiltration, and modified firewall configurations, accidentally taking one utility firewall offline. The Zerofot credential-harvesting operation, built with OpenAI Codex and Claude Code, collected 2,975 validated credentials from 1,742 hosts between April 5 and May 23, 2026, including SSH private keys and AWS access keys. The AI-generated RAGE Python framework exploits exposed Redis, Elasticsearch, Docker, Tomcat, and other services to harvest credentials and deploy cryptominers, guided at runtime by a DeepSeek-backed AI Orchestrator.
