It is perfectly legal to know your rights and to educate others about them, too.

EVERYONE in the United States, citizen or not, has rights. I will not allow this administration to intimidate us from helping you know about them.

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. 😊

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.

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. 😃

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.

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...

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.

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.

Enums in Binary Ninja have always been nice, but they are even better in the latest 4.3 update.

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?
Thanks for joining my talk about iPhone basebands at #OBTS #OBTSv7. It’s an awesome experience in Maui, and I’m looking forward to the rest of the conference. You can find the slides at lukasarnold.de/pdfs/obts7-t...

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!
Don't Panic! The answer: version 4.2 of Binary Ninja, is now available. Check out the release blog post which shows:
- New PseudoC/Python/Rust decompilation
- DLYD Shared Cache Support
- WARP Signature System

And many other impactful features.

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. 🤔
