You're telling me I can't load the entire dyld shared cache with 18GB?

ICE or not, always know your rights.

Alexandria Ocasio-Cortez @aoc.bsky.social · Feb 14

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.

Here’s our shareable guide ⬇️: (pt. 1/2)

KNOW YOUR
RIGHTS
IN CASE OF ICE:
CONOCE TUS DERECHOS
EN CASO DE ENCUENTRO CON ICE:

DO NOT OPEN YOUR DOOR.
ICE cannot enter your home without a warrant signed by a judge.
Tell the agents to show you the warrant by sliding it under the door.
NO ABRAS TU PUERTA.
ICE no puede entrar a tu casa sin una orden firmada por un juez. Diles a los agentes que te muestren la orden deslizándola debajo de la puerta.

ASK THEM
TO LEAVE.
If ICE doesn't have a warrant, tell them you do not consent for them to enter your home and ask them to leave. At work, ICE cannot enter employee-only areas without permission.
2
PÍDALES QUE SE VAYAN.
Si ICE no tiene una orden judicial, diles que no das tu consentimiento para que entren a tu casa y pídeles que se vayan. En el trabajo, ICE no puede ingresar a áreas exclusivas para empleados sin permiso.

REMAIN SILENT.
You have the right to remain silent.
If the agents ask you questions, tell them,
"I wish to remain silent."
PERMANECE EN SILENCIO.
Tienes derecho a permanecer en silencio.
Si los agentes te hacen preguntas, diles:
"Deseo permanecer en silencio".

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

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. 😊

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. 😃

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.

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?

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!

Binary Ninja @binary.ninja · Nov 20

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.

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. 🤔
