Almanac (YC S26) Launches Agentic AI with Self-Updating Company Wiki

FIRST LOOK ATLAS OWASP MEDIUM Moderate risk · Monitor closely ▲ 5.8 HN AI Security

Almanac is a persistent AI agent that connects to company tools, maintains a self-updating internal wiki, and executes multi-step work tasks autonomously via its own browser and login sessions. For defenders and security-conscious organisations, it introduces a structured, auditable knowledge graph of internal operations — every wiki entry links back to its source, providing a traceable record of AI-driven decisions and actions. Residual gaps centre on the maturity of access governance, wiki poisoning safeguards, and the breadth of autonomous action the agent can take before human confirmation is required.

Claude and ChatGPT Hijacked via Zero-Click Prompt Injection

Claude and ChatGPT Hijacked via Zero-Click Prompt Injection

ATLAS OWASP CRITICAL Active exploitation · Immediate action required ▲ 9.0 SecurityWeek

Zenity researchers disclosed a zero-click attack chain capable of hijacking Claude and ChatGPT's agentic browser capabilities through malicious content embedded in emails and X posts. The vulnerabilities, reported to Anthropic and OpenAI in late 2025 and early 2026, remain unpatched as of publication. This represents a significant escalation in prompt injection risk, as no user interaction is required to trigger malicious AI agent behaviour.
