Hex-Rays plugin contest: looking back at a 10-year journey

The Hex-Rays plugin Contest was an initiative by the experts behind IDA Pro, the state-of-the-art binary analysis tool. The contest, still taking place each year, encourages IDA users to create innovative and useful extensions for IDA and/or the Decompiler. 2019 marked its 10-year celebration. Hex-Rays deeply appreciates all participants for spending time and making this contest an incredible journey. […]

IDA 7.4 and Python 3.8

As several of our users have noticed, IDA 7.4 Windows installer refuses to use Python 3.8.0 if you installed it. You can usually observe output similar to following: ———- Checking installs from “Python Software Foundation” Checking “Python 3.8 (64-bit)” (3.8) Found: “C:\Program Files\Python38\” (version: 3.8.0 (’38’)) Ignoring unusable Python 3.8.0 No Python installations were found ———- So why exactly is 3.8.0 “unusable”? Well, […]

Hack of the day #1: Decompiling selected functions

Intended audience IDA 7.2 users, who have experience with IDAPython and/or the decompiler. The problem As you may already know, the decompilers allow not only decompiling the current function (shortcut F5) but also all the functions in the database (shortcut Ctrl+F5).A somewhat less-well known feature of the “multiple” decompilation, is that if a range is selected (for example […]

Augmenting IDA UI with your own actions.

Intended audience Plugin writers, either using the C SDK or IDAPython, who would like to add actions/commands to IDA UI in order to augment its capabilities. Rationale: before 6.7 APIs galore Depending on what type of context you were in, various APIs were available to you: Want to add a main menu item? add_menu_item(const char *menupath, const char *name, const char […]

Loading your own modules from your IDAPython scripts with idaapi.require()

TL;DR If you were using import to import your own “currently-in-development” modules from your IDAPython scripts, you may want to use idaapi.require(), starting with IDA 6.5. Rationale When using IDAPython scripts, users were sometimes facing the following issue Specifically: User loads script Script imports user’s module mymodule Script ends User modifies code of mymodule (Note: the module is modified, not the script) User […]

Recon 2012: Compiler Internals

This year I again was lucky to present at Recon in Montreal. There were many great talks as usual. I combined the topic of my last year’s talk on C++ reversing and my OpenRCE article on Visual C++ internals. New material was implementation of exceptions and RTTI in MSVC x64 and GCC (including Apple’s […]

Code viewer, forms & timers

In this post I’ll present some new things in IDA 6.2. There’s a new control, the code viewer, some additions to forms and the introduction of timers to discuss. All these new features have been exposed to the SDK, so that our users can benefit from them too. 😉

When choosers invade forms

With the upcoming IDA 6.1 it will be possible to create forms which host chooser controls. This feature will be available in the Qt and text version (not so in the VCL one).
