Highlights
Malcat has been designed for malware analysts, SOC operators, incident responders, CTF players or more generally anyone who needs to inspect unknown binary files on a regular basis. Have a look at its list of features to decide if it's the right tool for you:
Rapid analysis
Because Malcat does not run heavy analyses like VSA or type recovery, it can analyze most files under a second. This makes it the perfect tool for quick inspections or malware triage.
Disasm & decompile
Inspect code for architectures used in malware: x86/x64, .NET, python 2 and 3, VB p-code, NSIS vm, AutoIT and Office macros.
Malcat also embedds the Sleigh decompiler for x86 and x64.

Embedded files
Leveraging its numerous file format parsers, malcat can extract sub-files from archives and identify embedded objects within any file. A very useful feature for incident response and malware analysis.
Smart visualization
Malcat offers many view modes to focus on all aspects of the file. Inspect binary structures, naviguate through the CFG or have a higher-level look at the anomalies, you chose. You can also try our new DNA view!
Compare binaries
Compare two files side by side and inspect their structural differences using Myers algorithm, a powerful diff method used in bioinformatics which produce human-readable results and can realign.
Advanced editing
Patch the file content using the inline structure editor or using python.
Dealing with encrypted or encoded content? Just select the data and chose between dozens of decryption and decoding algorithms.

Known patterns
Malcat recognize and highlight more than 20000 standard strings and numerical constants.
You can also scan a corpus of local files or check online intelligence services.

Extract strings
Malcat features different algorithms to identify both static strings and dynamic strings (e.g. stack strings).
Strings are then weighted and sorted by score to give you the most pertinent results first.

Powerful UI
Enjoy a modern and responsive UI featuring HiDPI and full unicode support (hi .NET obfuscators :).

Make it your own
It is quite easy to extend malcat or automate file analysis by using the powerful python bindings.
You can create new file type parsers, decryption routines or add new anomalies with ease.

Get the software
Malcat is currently in beta phase. It means that while the software is finished and polished, it has not been tested extensively by its user base and documentation is sparse. So keep in mind, you may still encounter a few minor bugs. The good news is that during this time, Malcat is 50% off. So don't hesitate to pick one of the three editions of Malcat:
- Malcat Lite is a free (as in free food) edition with some limitations
- Malcat is the full version of the tool, affordable for hobbyists
- Malcat Pro is targeted toward computer infosec professionals. It allows commercial use and comes with support
Paid version gives you access to unlimited use of the software on Linux and Windows plateforms, and access to product updates for one year. Licenses are user-locked and allow installation on up to 3 different machines. If you are not sure if the software can run on your configuration, please test with the free lite edition first.

FAQs
Yes, Malcat can work offline, although you won't be able to use the intelligence scripts of course. There is a procedure to activate the software offline, you will just need a second computer with internet and python. Run the script bindings/activate.py for more details.
If you purchase a license, you may run the software for an unlimited period of time. You only get updates for one year though. After this period of one year, you may still run the software, but won't be able to get new updates until you renew your license.
You don't have to renew the license every year though, you may chose to renew your license at the time of your choice (even long after the 1 year threshold) and you will always benefit of the low license renewal price (50%). We don't want to milk users every year. It's up to us to convince you that Malcat's improvements are worth it.
The non-pro version of Malcat is targeted towards hobbyists: they will get all features of malcat for a reasonable price. The main limitation is that you are not able to use Malcat in a commercial/professional context. Also in order to keep the price low, no support is available in this version.
For now, only named licensed are available.
Purchase orders and invoices are supported for purchases of more than 5 copies of the Pro license. Contact us for more information.
There is no sutdent discount at this time, simply because verifying student status would cost too much time. Instead, we offer free 1-year licenses for IT-Security classes. Just ask your professor to contact us with a copy of your class curriculum and we will see what we can do.
