Critical Vulnerability in Claude Code Emerges Days After Source Leak Anthropic accidentally published a JavaScript sourcemap that exposed Claude Code's 512,000-line TypeScript operational blueprint, and researchers quickly reconstructed and redistributed the code. Separately, Adversa AI disclosed a critical permission-enforcement vulnerability that lets crafted prompt-injected command pipelines bypass deny rules, risking credential exfiltration and supply-chain or cloud compromise. #ClaudeCode #AdversaAI...

Anthropic's accidental leak of a 512K-line TypeScript sourcemap for Claude Code v2.1.88 enabled rapid code reconstruction. Adversa AI revealed a critical prompt injection flaw risking credential theft and cloud breaches. #AnthropicLeak #PromptInjection

AI Agent Hack: Prompt‑Layer Security Is the Real Threat The McKinsey AI agent hack sounds like sci‑fi: an autonomous agent “gains full read/write access” to a consulting giant’s chatbot in two hours. But what actually broke wasn’t some mystical AI defense, it was boring stuff: unauthenticated endpoints, sloppy SQL handling, and writable system prompts living in the same database as production data. Look, the key insight is this: agentic AI didn’t invent a new kind of attack; it just hits the weak spots you already left in your architecture at machine speed.

McKinsey AI hack wasn't magic—unauthenticated endpoints, sloppy SQL, writable system prompts. Agentic AI exploited your existing security holes at machine speed. #Cybersecurity #PromptEngineering #PromptInjection

The deeper lesson is that safety can fail in two places at once: incomplete command validation and weak observability across agent layers. If a lower-level agent can act while the top-level agent thinks it only detected risk, the system is not actually in control.
