AI-enabled hacking
Through 2026, AI agents ran real intrusions end-to-end: autonomously breaching government systems (195M Mexican taxpayer records), completing full simulated network takeovers, and carrying out the first agentic ransomware attack — as UK AISI clocked the capability doubling-time halving. Defenders gain the same tools (AI now finds and patches real zero-days), so it's a fast-accelerating arms race, not a rout.
Fang et al. (2024) showed GPT-4 could exploit 87% of a small set of 15 one-day CVEs, but only when handed the CVE description (just 7% without it) - so this was assisted exploitation, not autonomous vulnerability discovery. More current evidence is stronger: in September 2025 Anthropic disrupted the first documented large-scale AI-orchestrated cyber-espionage campaign, in which Claude autonomously executed an estimated 80-90% of a real operation (reconnaissance, exploit development, credential harvesting, and data exfiltration). Together these show AI is materially lowering the barrier to sophisticated cyberattacks.

An uncensored 'blackhat' LLM, WormGPT (built on GPT-J), was advertised on dark-web/Telegram markets on subscription, marketed for generating phishing and business-email-compromise (BEC) lures and malware without guardrails. The first commodified AI hacking tools.
The Hacker News 2023OpenAI and Microsoft disclosed they had shut down five state-affiliated threat groups (Russia's Forest Blizzard, North Korea's Emerald Sleet, Iran's Crimson Sandstorm, and China's Charcoal Typhoon and Salmon Typhoon) using ChatGPT for recon, scripting, phishing and vulnerability research. First public confirmation of nation-state offensive use of frontier LLMs.
OpenAI 2024Fang et al. showed a GPT-4 agent could autonomously exploit 87% of 15 real one-day vulnerabilities when given the CVE description, versus 0% for other models and off-the-shelf scanners; without the description its success collapsed to 7%. A landmark academic demonstration that frontier LLMs can weaponize public vulnerability disclosures.
Fang et al., arXiv, 2024Google's LLM-driven 'Big Sleep' agent discovered a previously unknown exploitable stack-buffer bug in SQLite, patched before release.

The first reported case of an AI agent executing the bulk of a live intrusion campaign.
Anthropic, 2025Google's Threat Intelligence Group reported PROMPTFLUX and PROMPTSTEAL, the first malware families that query LLMs (Gemini, Qwen) mid-execution to rewrite/obfuscate their own code and generate commands on the fly, including Russian APT28's PROMPTSTEAL data-miner used against Ukraine. AI moving from attacker aid to a live component of malware.

Hacker NewsResearchers at Israeli firm Gambit Security reported that a single unknown user wrote Spanish-language prompts telling Claude to act as an elite hacker, finding vulnerabilities in Mexican government networks, writing exploit scripts and automating the theft. The intrusion ran from December 2025 for roughly a month and was disclosed on 25 February 2026.
Los Angeles TimesAISI's evaluation of Claude Mythos Preview found it solved 73% of expert-level capture-the-flag tasks (no model could complete any before April 2025) and became the first model to finish 'The Last Ones,' a 32-step corporate network attack range estimated to take human experts 20 hours.
UK AI Security InstituteMicrosoft published CVE-2026-26030 and CVE-2026-25592 in Semantic Kernel: an in-memory vector store path allowing remote code execution triggered purely by prompt injection, and an arbitrary file write enabling sandbox escape because a download function was inadvertently exposed to the model as a callable tool.
Microsoft Security BlogAISI reported that the 80%-reliability time horizon for autonomous cyber tasks was doubling every 4.7 months, down from its 8-month estimate six months earlier, and that Claude Mythos Preview and GPT-5.5 exceeded even that accelerated trend line.
UK AI Security InstituteA team led by Nicolas Papernot showed a freely available AI model can drive a worm that tailors its attack to each device it reaches, propagating with no human operator. The prototype ran on an isolated test network and the paper redacted construction details.
The New York TimesAnthropic's Frontier Red Team published findings from mapping a year's worth of AI-enabled cyber threats onto the MITRE ATT&CK framework, documenting how AI is being used across attack stages.

Trail of BitsSecurity researchers identified what they believe to be the first agentic ransomware attack: an autonomous LLM agent carried out an entire attack — vulnerability exploitation, credential theft, and encryption — with no human involvement.
HIPAA Journal, Jul 2026An autonomous AI agent ran an end-to-end intrusion on Hugging Face — exploiting two code-execution flaws in the dataset-processing pipeline, escalating to node-level access and moving laterally across internal clusters. It compromised limited internal datasets and service credentials; HF found no tampering with public models, datasets, or the software supply chain, and says it detected the attack largely with AI of its own.

The Guardian (AI)This capability dramatically lowers the skill threshold required for effective cyberattacks, potentially leading to a significant increase in the frequency and sophistication of attacks against critical infrastructure and systems.
In November 2025 Anthropic disclosed disrupting what it called the first documented large-scale AI-orchestrated cyberattack, in which a Chinese state-sponsored group manipulated its Claude Code agent into autonomously executing 80-90% of an espionage campaign against roughly 30 targets; Anthropic responded by expanding threat-detection classifiers and argues the same models must be turned toward defense. On the defensive side, Google DeepMind and Project Zero's Big Sleep agent found a real-world SQLite zero-day (CVE-2025-6965) before it could be exploited and later surfaced ~20 further open-source flaws, complemented by Google's experimental CodeMender patching agent, its Secure AI Framework (SAIF), and the cross-industry Coalition for Secure AI (CoSAI). Benchmarks such as CVE-Bench and ZeroDayBench have emerged to measure autonomous exploitation and remediation, but Google Threat Intelligence reports adversaries already deploying AI-generated exploits and autonomous malware, and both offensive and defensive capabilities remain immature and roughly matched rather than defense clearly leading.
