BioShocking Attack Exploits Indirect Prompt Injection to Steal Credentials via AI Browsers

ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 9.0 The Hacker News

Security firm LayerX demonstrated a novel indirect prompt injection attack dubbed 'BioShocking' that manipulates AI browser agents into exfiltrating user credentials by embedding adversarial instructions inside web-based puzzle content. Six AI browsers and assistants were successfully compromised, including ChatGPT Atlas, Perplexity Comet, and Anthropic's Claude extension, with agents retrieving SSH credentials from GitHub repositories without triggering safety refusals. Vendor responses were inconsistent, with only OpenAI issuing a confirmed fix, highlighting the systemic risk of agentic AI systems that conflate user intent with malicious page content.

Cisco, Check Point M&A Targets AI Agent Identity Gaps

ATLAS OWASP MEDIUM Moderate risk · Monitor closely ▲ 6.2 SecurityWeek

May 2026 saw a wave of cybersecurity acquisitions with a clear focus on securing AI agents and LLM infrastructure, including Cisco's ~$400M acquisition of Astrix Security for non-human identity management and Check Point's acquisition of Deepchecks for LLM evaluation and continuous monitoring. Akamai also moved to acquire LayerX for AI usage control and agentic activity visibility across browsers and IDEs. These deals signal that enterprise security vendors are racing to build defensive capabilities around the expanding agentic AI attack surface.

Claude Chrome Extension Prompt Injection Enables Agent Takeover

Claude Chrome Extension Prompt Injection Enables Agent Takeover

ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 9.1 SecurityWeek

A vulnerability dubbed ClaudeBleed in Anthropic's Claude Chrome extension allows any browser extension to inject arbitrary prompts into the Claude AI agent by exploiting lax permission checks and improper trust validation. Attackers can bypass user confirmation protections via DOM manipulation and repeated message forging, enabling full agent takeover for information theft or unauthorized actions. The flaw effectively breaks Chrome's extension security model and exposes users running Claude's agentic capabilities to third-party extension compromise.
