APT Uses AI-Generated Lures in Google AitM Phishing on Taiwan

ATLAS OWASP HIGH ▲ 7.5 Cisco Talos Oct 08, 2026

Cisco Talos has identified a sophisticated APT campaign targeting Taiwan-based research organisations that leverages AI-assisted content generation to produce highly personalised spear-phishing emails impersonating legitimate academic and policy institutions. The operation combines QR code phishing and an adversary-in-the-middle framework to intercept Google credentials and bypass MFA in real time. Code analysis of the phishing kit suggests a Simplified Chinese-speaking developer, pointing toward a likely China-nexus threat actor.

TA419 AitM Phishing Targets US AI Policy Experts via Microsoft

ATLAS OWASP HIGH ▲ 7.8 The Hacker News Oct 06, 2026

China-aligned threat actor TA419 is conducting sophisticated adversary-in-the-middle credential phishing campaigns against U.S. AI policy experts at think tanks, universities, and law firms, impersonating prominent figures including Anthropic employees and former White House officials. The attacks leverage Frameless BitB techniques combined with OneDrive-hosted AitM pages to silently harvest Microsoft session cookies without alerting victims. This espionage campaign reflects Beijing's strategic intelligence priorities around U.S. AI policy, model regulation, and export controls.

Kimsuky Runs Offline LLMs to Sharpen Phishing, Build Malware

ATLAS OWASP HIGH ▲ 8.5 The Hacker News Aug 16, 2026

North Korean APT group Kimsuky has assembled a private, offline AI stack — including Ollama, GPT4All, and RAG tooling — to enhance spear-phishing lure quality and automate malware development in C#/.NET. South Korean firm Genians found configured instances of these tools on Kimsuky-linked infrastructure, alongside developer libraries such as LLaMaSharp and Microsoft Semantic Kernel, indicating deliberate integration of AI into the group's attack pipeline. The shift erodes traditional phishing detection signals like poor grammar and formatting, forcing defenders to pivot toward behavioural indicators on the endpoint.

GreyVibe Deploys ChatGPT and Gemini in LLM Attack Chain

ATLAS OWASP HIGH ▲ 7.5 SecurityWeek May 29, 2026

WithSecure has documented GreyVibe, a Russia-nexus threat actor systematically deploying ChatGPT, Google Gemini, and Ideogram AI across every phase of its attack chain — from phishing lure creation to custom malware development — against Ukrainian targets since August 2025. The group's LLM-assisted malware, LegionRelay, contained design flaws introduced during AI-generated development, which paradoxically allowed researchers to track the group over an extended period. The case illustrates both the operational leverage AI provides to moderately skilled threat actors and the novel forensic signatures that AI-assisted development can inadvertently introduce.

GreyVibe Uses ChatGPT and Gemini for Ukraine Cyberespionage

ATLAS OWASP HIGH ▲ 7.5 BleepingComputer May 29, 2026

A likely Russian threat group dubbed GreyVibe has been actively using commercial LLMs — including ChatGPT and Google Gemini — to generate high-quality phishing lures, malware tooling, and social-engineering content targeting Ukrainian military, government, and civilian organisations. WithSecure researchers identified LLM artefact markers embedded in campaign imagery, confirming AI-assisted content generation at scale. The case represents a concrete, documented example of adversarial LLM weaponisation in an active nation-state-adjacent cyberespionage campaign.
