Google Gemini Voice Prompt Injection via Notifications

ATLAS OWASP HIGH ▲ 8.2 Dark Reading Jun 04, 2026

A prompt injection vulnerability in Google Gemini's voice assistant allows attackers to embed malicious instructions within device notifications, which the assistant then processes as legitimate commands. This attack vector enables social engineering, unauthorized actions, and potential data exfiltration without direct user interaction with the malicious payload. The flaw highlights the growing risk of indirect prompt injection in ambient AI assistants that consume untrusted content from the surrounding environment.

ChatGPT Sharing Links Abused for Malware Delivery

ATLAS OWASP HIGH ▲ 7.5 BleepingComputer May 31, 2026

Threat actors are exploiting ChatGPT's legitimate content-sharing infrastructure to host convincing fake outage pages that trick users into downloading malware disguised as a ChatGPT desktop application. The 'LLMShare' campaign abuses chatgpt.com/s/ shared links to render attacker-crafted HTML within a trusted OpenAI domain, bypassing traditional phishing detection that relies on suspicious URL analysis. The attack chain combines Google ad abuse, domain cloaking, and AI platform misuse to deliver what are likely infostealer payloads.

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.

Account Takeover Protection: OpenAI Hardens ChatGPT Auth

ATLAS OWASP MEDIUM ▲ 6.2 Wired Security May 01, 2026

OpenAI has introduced Advanced Account Security, an optional hardened authentication mode for ChatGPT and Codex users who face elevated risk of account takeover, including journalists, dissidents, and researchers. The feature enforces passkey or physical security key authentication, eliminates SMS/email recovery routes, and removes OpenAI support team access to recovery options to block social engineering attacks. Members of OpenAI's Trusted Access for Cyber programme will be mandated to enable it or provide equivalent enterprise SSO attestation by June 1.

Model Extraction Attacks Surge: Google GTIG Q4 Report

ATLAS OWASP HIGH ▲ 8.5 Mandiant Blog Apr 26, 2026

Google Threat Intelligence Group's Q4 2025 AI Threat Tracker documents a meaningful escalation in adversarial AI misuse, including a surge in model extraction (distillation) attacks, nation-state operationalisation of LLMs for phishing and reconnaissance, and the emergence of AI-integrated malware families such as HONESTCUE that leverage Gemini's API. While no breakthrough capabilities have been observed from APT actors, the integration of agentic AI for tooling development signals a maturing threat landscape. Defenders should prioritise monitoring for model extraction activity, API abuse, and AI-augmented social engineering campaigns.
