From Indirect Prompt Injection to DNS Exfiltration in macOS Terminal
Apple patched a macOS Terminal behaviour that allowed indirect prompt injection to chain into DNS-based data exfiltration via ANSI escape codes—a reminder that LLM output rendered in terminals can trigger OS-level side channels.

This is a follow-up to my previous Terminal DiLLMa research , and there is a positive outcome: Apple fixed a macOS Terminal behavior that enabled a DNS-based data exfiltration technique. DNS Requests via ANSI Escape Codes David Leadbeater originally discovered an interesting behavior in the macOS Terminal app that allowed a special sequence of ANSI escape codes to issue DNS requests. In short, this triggered a DNS request from the macOS Terminal app:
Editorial Analysis
As enterprises integrate LLMs into developer workflows, this research shows that untrusted model output rendered in terminals can exploit OS-level features for silent data exfiltration.
Audit developer toolchains that pipe LLM output to terminal emulators and ensure macOS endpoints are updated to include Apple's fix.
