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.

In this post, we’ll explore how we used Sidekick to analyze complex malware samples. We’ll use LockBit 3.0 as our target, walking through the process of identifying and understanding key functions, deobfuscating strings, and mapping the sample’s behavior.

If you’ve been following our social media accounts, this is no surprise, but last year we at Vector 35 launched RE//verse, a new reverse engineering conference that’s happening in Orlando, FL from Feb 27 - Mar 1 (kickoff reception 27th, talks 28th-1st, trainings 24th-27th). As we’re a month out we wanted to highlight some of the goals behind the conference, talk about what it is and what it isn’t, and remind anyone that hasn’t already signed up and booked their hotel to move fast! We still have trainings and tickets available, but the conference room rate is ending soon so don’t wait.
