For the last few months, we’ve been hard at work on today’s release, Binary Ninja 5.2 (Io)! This release delivers some of our most impactful and highly requested features yet, including bitwise data-structure support (second most requested), container support (fifth most requested), full Hexagon architecture support for disassembly and decompilation, and much more. Under-the-hood, 5.2 also contains some other improvements that will help us chart a course toward even bigger improvements in the future.

Update: A second release (R2) with stability improvements and bug fixes is now available.

Let’s dig in!

Since Binary Ninja 4.2, users have been able to enable WARP, and now with Binary Ninja 5.1 we are finally enabling it by default! WARP has received many features users have been asking for, and a healthy amount of polish on top of that as well. In this blog we’ll describe what WARP is, how it works, and how you can use it to improve your reverse engineering experience.

We’re back with a small hotfix for our recent 5.1 Helion release. Following our usual practice for stable releases, we’ve bundled together several important fixes that have come to light since the original 5.1 launch, along with a new Sidekick sidebar feature.

This release focuses on stability improvements across WARP, the debugger, and Enterprise collaboration, plus some nice UI enhancements. For users on our development branch, these fixes are already available alongside additional features.

With the 5.1 Helion release, we introduced a new capability for architecture plugins that enables function-level basic block analysis by overriding the default implementation. This feature provides powerful new flexibility for performing control-flow recovery on architectures where instruction-level or even basic block-level analysis alone is inadequate for building an accurate control flow graph (CFG). In this post, we demonstrate how this mechanism can be leveraged to resolve zero-overhead hardware loops and accurately identify branch targets in parallel instruction pipelines.

Global pointer usage is an important yet often overlooked concept in reverse engineering. This article explains what it is, how it interacts with Binary Ninja’s analysis and the relevant APIs and settings. This can hopefully help you master it in your day-to-day reverse engineering!

We’re excited to announce Sidekick 5.0 - our latest vision for AI-assisted reverse engineering with Binary Ninja. In this release, Sidekick comes with a new capability to proactively work on tasks that complement your efforts without requiring your supervision. Sidekick also captures and maintains insights from this analysis in a new, fully editable knowledge store called the Notebook. Additionally, we’ve made many important changes and improvements to ensure that Sidekick continues to make reverse engineering faster and easier than ever.

Binary Ninja 5.1 might not help you see in the dark like Riddick (our 5.1 Helion release is named after a system from the Riddick universe), but it WILL help you reverse engineer better! With a bunch of quality of life improvements, bug-fixes, and even a few new features, we’re continually working to improve your reversing experience. We’re introducing WARP, our new static function matching system, which will be helping not only Binary Ninja users in the future, but the entire reverse engineering community. Also, we’re shipping the BinExport plugin pre-built for all platforms, for easy integration with BinDiff. Finally, we’ve added a ton of improvements to the readability and presentation of decompilation, better tooling for re-writing IL with scripts, and a ton of architecture improvements.

We’re excited to announce the launch of our new developer portal within the Binary Ninja Portal. This new feature provides a centralized hub for viewing extensions, gives extension developers the ability to manage their extensions, and provides extension authors insights into their user base.

While our customers with active support on the development branch have access to these changes and more, we occasionally release updated stable releases just to include a few fixes that we either did not identify during stable release testing or those for whom a fix was scheduled after the original stable release.

This 5.0 Release 2 build improves on our recent 5.0 release with a few small stability improvements and fixes.

Reverse engineering often requires quickly finding a proverbial needle in a haystack. Whether hunting for specific byte signatures, cryptographic constants, or matching instruction patterns, the ability to efficiently locate precise byte sequences within binaries is essential. This post introduces the Advanced Binary Search (ABS) search mode in Binary Ninja (BN), designed to streamline the most common reverse engineering search tasks.
