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.

Today, let’s talk about Firmware Ninja, functionality included in Binary Ninja Ultimate Edition that speeds up firmware analysis by offering specialized capabilities tailored to the complexities of embedded reverse engineering.

The battle for the default browser on Windows has always been heated. You might have heard of how Microsoft leveraged its UCPD (User Choice Protection Driver) to prevent third-party browsers from setting themselves as the default one. However, in this post, I will show my journey into uncovering how various browsers try to bypass the restriction, and how UCPD gets updated to defeat their attempts.

Note: this is an extended version of my lightning talk at RE//verse. Please also check out the video and slides.

We’re excited to share some significant news about Binary Ninja’s role in improving medical device security. Through a collaborative effort with STR and Aarno Labs under the ARPA-H DIGIHEALS program, our platform has helped identify critical vulnerabilities in widely-used hospital patient monitoring systems.

Today, we are excited to announce Sidekick 3.0! In addition to a number of bug fixes, UX improvements, and updated models, this release extends Sidekick’s analysis capabilities and with tighter Binary Ninja integration. In particular, our new query language, expanded editing capabilities, custom tool system, and the re-designed Assistant (now called the Analysis Console) stand out. These features and more continue to make Sidekick the best AI-powered tool for binary analysis on the market.

Hello, and welcome to another exciting episode of “Sidekick in Action”! Today, we will be applying Sidekick to a variety of common vulnerability discovery tasks while looking at the popular network utility dnsmasq.
