Duplicate License Emails

Apologetic Binary Ninja >

This evening at 17:56:47 ET on 2024-12-05, a bug in our license/update server caused a large number of license emails to be sent to users with an active license. The short summary is that this was not a security incident, no customer data was exposed, no extra purchases were triggered. We don’t actually have the ability to trigger additional purchases as we don’t store payment information, our credit card processor handles those details.

If you’d like more details into the timeline, what happened to cause the bug and what we’ve done to prevent it from happening again, read on!

4.2 Frogstar

Dont Panic Text With Binary Ninja Mascot Holding a Towel >

Don’t panic! Binary Ninja version 4.2 Frogstar is here. It is, after all, the answer to everything. Much like a trusty towel, you’ll find that the improvements in 4.2 are applicable to many situations. This major release (despite the number increment being minor since we couldn’t skip version 4.2) includes an industry-first multiple-language decompilation, DYLD Shared Cache analysis, MSVC RTTI support, a new signature system fittingly called WARP, and so many more features.

Objective-C Update

We’ve been very hard at work improving the experience for our iOS and macOS reverse engineers. You’ll want to keep an eye out for our upcoming 4.2 feature release announcement stream which includes some even juicier bits. In the meantime, hopefully this will tide you over.

This blog is a short summary of the current state of Objective-C analysis in Binary Ninja.

Plugin Spotlight: CoolSigMaker

EDITOR’S NOTE: This guest-post was brought to you by unknowntrojan, shedding light on one of the lesser-known plugins, coolsigmaker.

A common desire in reverse engineering is to match re-used code across multiple binaries. Whether you’re doing malware lineage tracking, identifying a statically compiled library, or any other use case about identifying similar code, there are multiple technologies that attempt to solve parts of this problem. Other tools for related problems include SigKit (Binary Ninja’s static library detection), IDA’s FLIRT/FLAIR and Lumina features, or even more advanced systems like Diaphora or BinDiff.

Related to those, you might already be familiar with the “SigMaker” style of plugins for various platforms[1] [2] [3]. These plugins generate patterns from code that can be used to find said code across different binaries or find the same function reliably between application updates. This is useful for malware classification and static-library identification among other purposes.

binja_coolsigmaker is just that: a fast and reliable “SigMaker” plugin for Binary Ninja.

Binary Ninja Ultimate

Binja character getting a powerful upgrade for his prosthetic arm >

Today, we are releasing the newest edition of our flagship product: Binary Ninja Ultimate.

The Ultimate edition includes all of the same features you know and love from Binary Ninja Commercial, but also includes the architectures we’ve been selling separately over our past few releases. This lets us simplify our release pipeline and our pricing at the same time without raising prices for any existing customers. For the next few months, we’ll be selling this edition at a reduced, introductory price as we continue to build out additional features.

Under-the-hood, Binary Ninja Ultimate is a re-brand of our existing Binary Ninja Enterprise client builds, but now with named (instead of just floating) licenses. This means all current Enterprise customers will get Ultimate features at no extra cost and all future Ultimate customers will have the ability to add an Enterprise server at any time.

Some additional clarifications up-front for our existing customers:

  • If you’re a Non-Commercial customer, nothing is changing.
  • If you’re a Commercial customer happy with our existing architecture support, nothing is changing.
  • If you’re an Enterprise customer, you will receive many new architectures for free with your existing licenses!
  • If you had previously purchased a license to nanoMIPS or TriCore (speaking of which, make sure to catch up on our other blog post today with much more detail about our TriCore support), you will receive a free upgrade to Binary Ninja Ultimate.

TriCore Architecture

TriCore firmware is important for security researchers since it is found in a wide range of car components. While we originally announced the availability of a separate paid TriCore plugin in our 4.1 release, we have since updated it and are excited to now ship TriCore to all Binary Ninja Ultimate customers! This not only makes it cheaper and enables access to other architectures, but makes getting access easier than ever. If you haven’t heard of Ultimate yet, check out our other announcement from today!

Advanced UEFI Analysis with Binary Ninja

The Unified Extensible Firmware Interface (UEFI) is a specification that defines the architecture of firmware used for booting computers. It contains the initial code that runs on most modern PCs and mobile devices, operating at the highest privilege levels before the operating system loads. This makes UEFI a fascinating area for reverse engineering.

Let’s delve into some firmware samples and demonstrate how Binary Ninja and our official EFI Resolver plugin can automate the analysis of UEFI binaries. The features highlighted in this blog post represent a culmination of efforts that began prior to the release of Binary Ninja 3.5. This ongoing work includes recent contributions by Zichuan, one of our summer interns!

4.1 Release 2

Much like our 4.0 re-release, we are releasing an updated 4.1 with a few additional changes. As always, you can switch to the dev channel to receive these fixes and more, while build 4.1.5902 released today is for those who prefer to stay on stable releases.
