This is a special post because I fully based on another researcher, s1guza’s 0day. All of this story began from the following tweet:
Siguza told us that his 0day was patched in the iOS 13.5 beta3. So this is actually a sandbox escape 0day for the newest, non-beta iOS version (13.4.1). In this post, I’ll show you how I reproduced that bug and wrote a malicious application that uses that 0day to steal the iMessage history!
