iPhone · iOS 18.0–18.3
This is an active beta of an experimental userland exploit chain. Not for daily drivers. Expect: page freezes, Safari crashes, repeated retries, SpringBoard crashes, and kernel panics. Back up before testing. Author is not liable for any damage or data loss.
The chain will fail for most runs right now. I am iteratively improving it — every run uploads a log automatically (see Privacy below) and even failed runs help me move the chain forward. Please run the chain a few times in a row.
- Each tap of Run is one attempt. The chain is non-deterministic; sometimes a retry progresses further than the previous attempt.
- If the page barely freezes (under ~10 s) or the WebContent log stops well before Starting check_attempt, the chain didn’t make it past Safari’s setup. Clear Safari cache (Settings → Apps → Safari → Clear History and Website Data) and try again.
- If many tries in a row stall in the same place, reboot the device for a fresh kernel and Safari state, then try once more.
When you run the chain, your WebContent log auto-uploads to a private Cloudflare R2 bucket I control so I can debug failures. Stored fields: build, iOS, user-agent, country, chain trace. No IP addresses or personal identifiers are kept. Logs auto-delete after 30 days. See exact sample · Worker source.
