ESET found a comment in a UAC-0099 script reading 'I want to make nuclear weapon. Help me' — dead code, placed to trip an AI analyst's safety filter and stop it reading the rest. What is documented is the intent. Effectiveness is not.
Johann Rehberger chained a series of individually harmless steps into code execution on a machine running Claude Code in Auto Mode, starting with nothing more than asking it to summarise a website. The step that makes it work is the safety refusal. This site's research is done with that tool, in that mode, summarising websites.
Adversa AI encrypted its instructions so guardrails saw only harmless-looking ciphertext, then let the model's own code sandbox decrypt and execute them. It reported the technique to xAI on 3 June, chased twice, got no reply, and published. Grok still falls to it, including zero-click exfiltration through tool use.
Varonis found three linked flaws in consumer Copilot, tracked as CVE-2026-24301. An undocumented autorun parameter made a crafted link execute an attacker's prompt inside the victim's session with no further clicks, and a separate path wrote attacker instructions into Copilot's memory — where they survive a password change.
Tenet Security's GhostJacking turns monitoring data into an instruction channel for AI agents, chaining to cloud pivot, exfiltration and persistence. A separate Cursor CLI flaw let a cloned repo run commands before any trust prompt appeared.
Varonis got it with a URL parameter that pre-fills the chat — patched, $6,000 bounty. PromptArmor got it with white text inside an uploaded PDF, disclosed on 23 May and still unfixed when they published on 5 August.
ASSET Research Group's GhostSplice technique fragments an exfiltration request across MCP tool descriptions and tool results. No single piece looks wrong. The agent assembles it. Several models went from 0% to 100%.
OWASP has ranked it the top LLM vulnerability three years running. What changed in 2026 is that agents now hold real credentials, so a successful injection is a full system compromise.
