What this means for you — Security leader:Prompt injection tops OWASP’s latest LLM Top 10 and was used to exfiltrate data from Amazon Kiro IDE via its Powers feature; no technical mechanism has been disclosed in the Kiro report.
What this means for you — Lean IT orgs:If your team uses any LLM tools or AI features inside apps, treat every user prompt as potentially attacker-controlled and avoid feeding them sensitive data or system commands.
What this means for you — MSP:Audit client LLM integrations and agentic tools for prompt-injection paths; add output validation and privilege boundaries especially on any IDEs or automation that can call external functions.
What this means for you — Researcher:OWASP still ranks prompt injection #1 for LLMs; the Kiro case shows real exfiltration potential in agentic IDEs, but the vendor has not published the exact attack chain or payload.
