Chinese language hackers automated 90% of an espionage marketing campaign utilizing Anthropic’s Claude, breaching 4 organizations of the 30 they selected as targets.
"They broke down their attacks into small, seemingly innocent tasks that Claude would execute without being provided the full context of their malicious purpose," Jacob Klein, Anthropic's head of menace intelligence, advised VentureBeat.
AI fashions have reached an inflection level sooner than most skilled menace researchers anticipated, evidenced by hackers with the ability to jailbreak a mannequin and launch assaults undetected. Cloaking prompts as being a part of a respectable pen testing effort with the intention of exfiltrating confidential knowledge from 30 focused organizations displays how highly effective fashions have turn into. Jailbreaking then weaponizing a mannequin towards targets isn't rocket science anymore. It's now a democratized menace that any attacker or nation-state can use at will.
Klein revealed to The Wall Road Journal, which broke the story, that "the hackers conducted their attacks literally with the click of a button." In a single breach, "the hackers directed Anthropic's Claude AI tools to query internal databases and extract data independently." Human operators intervened at simply 4 to 6 choice factors per marketing campaign.
The structure that made it attainable
The sophistication of the assault on 30 organizations isn’t discovered within the instruments; it’s within the orchestration. The attackers used commodity pentesting software program that anybody can obtain. Attackers meticulously broke down advanced operations into innocent-looking duties. Claude thought it was conducting safety audits.
The social engineering was exact: Attackers introduced themselves as workers of cybersecurity corporations conducting licensed penetration exams, Klein advised WSJ.

The structure, detailed in Anthropic's report, reveals MCP (Mannequin Context Protocol) servers directing a number of Claude sub-agents towards the goal infrastructure concurrently. The report describes how "the framework used Claude as an orchestration system that decomposed complex multi-stage attacks into discrete technical tasks for Claude sub-agents, such as vulnerability scanning, credential validation, data extraction, and lateral movement, each of which appeared legitimate when evaluated in isolation."
This decomposition was crucial. By presenting duties with no broader context, the attackers induced Claude "to execute individual components of attack chains without access to the broader malicious context," in response to the report.
Assault velocity reached a number of operations per second, sustained for hours with out fatigue. Human involvement dropped to 10 to twenty% of effort. Conventional three- to six-month campaigns compressed to 24 to 48 hours. The report paperwork "peak activity included thousands of requests, representing sustained request rates of multiple operations per second."

The six-phase assault development documented in Anthropic's report exhibits how AI autonomy elevated at every stage. Part 1: Human selects goal. Part 2: Claude maps the complete community autonomously, discovering "internal services within targeted networks through systematic enumeration." Part 3: Claude identifies and validates vulnerabilities together with SSRF flaws. Part 4: Credential harvesting throughout networks. Part 5: Knowledge extraction and intelligence categorization. Part 6: Full documentation for handoff.
"Claude was doing the work of nearly an entire red team," Klein advised VentureBeat. Reconnaissance, exploitation, lateral motion, knowledge extraction, have been all occurring with minimal human course between phases. Anthropics' report notes that "the campaign demonstrated unprecedented integration and autonomy of artificial intelligence throughout the attack lifecycle, with Claude Code supporting reconnaissance, vulnerability discovery, exploitation, lateral movement, credential harvesting, data analysis, and exfiltration operations largely autonomously."
How weaponizing fashions flattens the price curve for APT assaults
Conventional APT campaigns required what the report paperwork as "10-15 skilled operators," "custom malware development," and "months of preparation." GTG-1002 solely wanted Claude API entry, open-source Mannequin Context Protocol servers, and commodity pentesting instruments.
"What shocked us was the efficiency," Klein advised VentureBeat. "We're seeing nation-state capability achieved with resources accessible to any mid-sized criminal group."
The report states: "The minimal reliance on proprietary tools or advanced exploit development demonstrates that cyber capabilities increasingly derive from orchestration of commodity resources rather than technical innovation."
Klein emphasised the autonomous execution capabilities in his dialogue with VentureBeat. The report confirms Claude independently "scanned target infrastructure, enumerated services and endpoints, mapped attack surfaces," then "identified SSRF vulnerability, researched exploitation techniques," and generated "custom payload, developing exploit chain, validating exploit capability via callback responses."
Towards one expertise firm, the report paperwork, Claude "independently query databases and systems, extract data, parse results to identify proprietary information, and categorize findings by intelligence value."
"The compression factor is what enterprises need to understand," Klein advised VentureBeat. "What took months now takes days. What required specialized skills now requires basic prompting knowledge."
Classes realized on crucial detection indicators
"The patterns were so distinct from human behavior, it was like watching a machine pretending to be human," Klein advised VentureBeat. The report paperwork "physically impossible request rates" with "sustained request rates of multiple operations per second."
The report identifies three indicator classes:
Site visitors patterns: "Request rates of multiple operations per second" with "substantial disparity between data inputs and text outputs."
Question decomposition: Duties damaged into what Klein known as "small, seemingly innocent tasks" — technical queries of 5 to 10 phrases missing human shopping patterns. "Each query looked legitimate in isolation," Klein defined to VentureBeat. "Only in aggregate did the attack pattern emerge."
Authentication behaviors: The report particulars "systematic credential collection across targeted networks" with Claude "independently determining which credentials provided access to which services, mapping privilege levels and access boundaries without human direction."
"We expanded detection capabilities to further account for novel threat patterns, including by improving our cyber-focused classifiers," Klein advised VentureBeat. Anthropic is "prototyping proactive early detection systems for autonomous cyberattacks."
