Apple released CloudOS firmware images for iOS 26.4 and 26.4.1, none of the images contain vphone600 files. Meaning it is not possible to virtualize these versions
@CodeColorist considering sb compiler optimizations, if deterministically comparing binary forms is possible, this may give you 100% correct success evaluations:
compile(oss sb)) vs compile(decompile(compile(oss sb)))
@CodeColorist The article claimed MTE instructions are just in allocator libraries so won't appear in executables; which is wrong.
Also it mentioned fbounds-safety is hard to detect on binary, but the emitted disassembly is distinguishable enough even for not-so-pedant reverser I believe.
