Quite slick. Thanks for sharing the example source as well. 🙂

Decompilers and Performance Cores How well does Binary Ninja utilize Apple Silicon’s P-cores? More P-cores lead to faster decompilation—worth considering when choosing your next M-series chip.

How well does Binary Ninja's decompiler utilize Apple Silicon P-cores? Pretty well. If you're a reverse engineer looking for a new machine, opt for more cores.

Seems obvious, but I had to test. 😊

Activating an iPhone 3G in 2025 Turns out that activating older iPhones is no easy feat in 2025 or macOS Sequoia. Using iOS Legacy Kit solves this problem.

It turns out that activating an iPhone 3G in 2025 isn't as easy as opening up Finder and restoring. I've written up a blog post to help anyone else in this predicament. 😃

Love this! I just finished chapter four today (not in Korean 😆). Thanks for sharing your expertise.

A snippet from macOS' Activity Monitor showing 18GB of total Physical Memory with 9GB of Swap Used.

If you're not utilizing 150% of your available RAM, you're leaving money on the table.

Or at least that's what I tell myself so I don't need to upgrade quite yet...

Thank you for sharing! I’ll give them a read this week!

Trying Out Binary Ninja's new WARP Signatures with IPSW Diff'ing Binary diff'ing is pretty complex, but being able to apply markup from one binary to another is quite powerful. Binary Ninja's new WARP extends previous efforts, using SigKit, to quickly identify libr...

Binary diff'ing is hard. But it's super powerful to apply markup from previous reverse engineering efforts to a new binary.

Binary Ninja is switching up how they match function signatures with WARP.

Swap is going to kill this SSD. Also check out their new DSC plugin. Works great.

Oh nice, my Binary Ninja Wrapped 2024 is in!!

Enums Just Got So Much Better in Binary Ninja Enums in Binary Ninja have always been nice, but they are even better in the latest 4.3 update.

Setting enums in Binary Ninja previously broke down when any enum member was set to zero.

@binary.ninja 4.3.x now ignores any 0 value for enums, when used as bitfield masks, to aid readability.

Highly recommend checking out @lukasarnld.bsky.social’s talk on the iOS baseband. It’s up on the OBTS YouTube livestream right now. Video out in a couple days?

Great talk. I learned a ton. Going to check out your app this weekend. 🤙

What could be better than surfing in the morning and then hacking with @naehrdine.bsky.social and Alex in their Objective by the Sea training “Practical iOS App, User-, and Kernel-Space Reverse-Engineering”

Gotta RE 'em All: Reversing C++ Virtual Function Tables with Binary Ninja C++ can be frustrating to reverse engineer. Explore how to reverse engineer those with Binary Ninja.

Reversing C++ structures can be tricky. Binary Ninja makes it easier. I wrote up a walkthrough to clean up those pesky vtables. @binary.ninja

About to do the same lol.

Comparing Binary Ninja Performance on the M1, M2 Ultra, and M3 Pro We test the time to decompile programs in Binary Ninja over various Mac configurations. No surprise, but the M2 Ultra fared pretty well.

So I benchmarked how much faster the newer Apple silicon chips were in decompiling programs with Binary Ninja. No surprise, the M2 Ultra performed well. Also, RAM is important. @binary.ninja

DYLD 👀 it's getting better and better with iOS reversing support!

Can confirm this works pretty well. Mapping in one .dylib at a time is certainly saving my SSD from all that previous swap. Thanks @binary.ninja.

There are tons of YouTube videos comparing Apple’s M4 lineup against Adobe Lightroom, Photoshop, Final Cut Pro, etc.

We need a channel or blog for reverse engineers that shows how much faster I can decompile the dyld shared cache with the M4 Max over the Pro. 🤔

What you think, you become.

Thanks for sharing a great writeup! This was something I was super curious about.
