State Of IOS Jailbreaking In 2025
summary
Explains a practical jailbreak chain that reaches full system control on iOS 15–16.5 by combining a TrollStore code‑signing bypass (multi‑signer/CARTrust flaw used to fake SHA‑256 entitlements) with a kernel exploit plus a PPL/PAC bypass to get kernel read/write. Implements a persistent jailbreak named Dopamine that injects a patched dyld via launchd, hooks posix_spawn and fcntl, and inserts dynamic trust cache entries so any binary or library can run; kfdL and Kasperkski’s PPL bypass are the concrete CVEs used, but iOS 17/18 requires new bugs and currently shows no ETA.
