Calif says its Hexacon demonstrations will be released later

Calif said on October 16, 2026, that the demonstrations it presented at Hexacon in Paris would be released “in due time.” Its newsletter named no release date and did not specify that a usable public jailbreak tool would be part of the release. Separately, Cyber Security News reported that one demonstration involved an untethered jailbreak on an iPhone 18 Pro running iOS 27.0.1. Calif’s newsletter

What the iPhone 18 Pro demonstration showed

Calif’s post about its Hexacon demonstrations said they were presented in Paris that day.

Cyber Security News identified the phone in its account as an iPhone 18 Pro running iOS 27.0.1, build 24A446. It described a reboot followed by the lock screen, the phone’s ordinary passcode unlock, and then an SSH session on port 2222 that returned uid=0, the root user identifier. (Cyber Security News)

Here, “untethered” means the jailbreak reportedly returned after a reboot without reconnecting the phone to a computer. The described sequence included the normal passcode entry before root access. Heise reported that the presentation described compatibility across the iPhone 18 Pro family through iOS 27.0.1. (Heise)

The two-minute reading in the account was the phone’s uptime since reboot. Pasquale Pillitteri also described it as elapsed uptime, not the time the jailbreak took to run. (Cyber Security News; Pasquale Pillitteri)
