Quick Answer: Security firm Calif demonstrated an untethered jailbreak on an iPhone 18 Pro running iOS 27.0.1 at Hexacon in Paris on 16 October 2026. Root access came back after a reboot. No tool or exploit details have been released, so any "iOS 27 jailbreak" download you find online is a scam. Keep your iPhone updated.
Last updated: 23 October 2026. This is a developing story and I will update it when Calif publishes details.

The real event happened at the Hexacon offensive security conference in Paris, and it is a genuine technical milestone. But it is a research demonstration, not a download. Here is what is confirmed, what is still unknown, and how to avoid the scams riding on the headlines.
