When should you use Malcat?
Malware investigations often start with an unknown file: an installer, archive, document, executable or memory dump. Before following its code, you need to understand its structure, locate embedded content, identify suspicious regions and recover the next stage.
Malcat brings these steps into one fast, local analysis environment. Its parsers, disassembler, decompiler, Kesakode, anomaly scanner, native capa engine, YARA editor and data transforms work on the same analysis. You can follow a finding into the bytes or code, unpack a payload, extract its configuration, write a detection and automate the investigation through Python or MCP.
That makes Malcat useful for both rapid triage and detailed malware analysis. IDA Pro and Binary Ninja provide extensive code analysis, type recovery and debugging. Compare the capabilities supplied with each product against the investigation you need to perform.

Frequently asked questions
How long can I use/update the software? Do I need to renew every year?
If you purchase a license, you may run the software for an unlimited period of time. You only get updates and access to the online Kesakode service for one year though. After this period of one year, you may still run the software (and use the offline Kesakode scanner), 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.
Can I use Malcat in an isolated environment?
Yes, Malcat can work offline, although you won't be able to use the intelligence scripts of course, and Kesakode will be limited to offline scans. There is a procedure to activate the software offline, see our our manual for more details.
What do you mean by "commercial use"?
Commercial use means use in your daily (paid) job or in any activity that directly or indirectly generates revenues. Here are two examples that may be helpful:
- Non-commercial usage: You are a network administrator at a commercial organization with discretionary budget and have been practicing CTF on your own time using work resources (approved by work). Your usage qualifies for non-commercial use as you are using Malcat purely for educational, non-commercial purposes.
- Commercial usage: You are a network administrator at a non-profit or government organization who regularly engages in malware analysis as a part of your job. You plan to use Malcat to analyze malware during paid work-hours. Your use is commercial.
We also apply a "de minimis" standard. If your use (running ads on Youtube videos, for example) makes you less money than 5 times the cost of a pro license, we're happy to have you continue to use a personal license. Once you start making above this amount, we ask that you then upgrade. If you have a doubt, contact us for more information.
Can I try Malcat before buying?
Malcat Lite is free for non-commercial use, with no time limit. You may use it 30 days in a commercial environment for testing. See the edition comparison for features and usage rights.
Can I use Malcat (or its headless module) in my tool chain?
If you own a named license, which is the case if you bought it from this website, the license is bound to you and only you. As stipulated in the EULA, it means that you cannot rent or make the software available to other users. This includes the integration of the python module into any user-facing program and/or service. Here are some examples of what you may or may not do with your personal license:
- OK: You are a SOC analyst. You've made a script to assist you in your job which automatically updates your incident tickets with information coming from Malcat. This fits within the bounds of a named license.
- Not OK: You are a SOC analyst. You've made a script that automatically updates all incident tickets of your SOC with information coming from Malcat and integrated it in the SOC stack of your company. This is assimilated to sharing the software with other users.
- OK: You are a security/academical researcher and used Malcat's python module and its CFG reconstruction to analyse large batch of files and do machine-learning detection. You have published the result of your research online. This all fits within the bounds of a named license.
- Not OK: You are a security/academical researcher and used Malcat's python module and its CFG reconstruction to analyse large batch of files and do machine-learning detection. You have additionally made a online service where users can scan their files online using your technology. This also assimilated to sharing the software with other users.
No trick there, this is merely common sense. If you want to integrate Malcat in a multi-user software and/or online service, you can contact us and we will work a OEM integration out. Don't worry, chances are it will be much cheaper than the concurrence.
Does Malcat replace IDA Pro or Binary Ninja?
For many malware investigations, Malcat can be your main analysis tool: inspect the container, extract its payloads, identify the family, follow code and strings, recover configuration data and write or test detections. Its shared analysis and integrated tools are useful throughout that work, including detailed investigations.
IDA Pro and Binary Ninja are useful when your task needs their processor coverage, interactive debugging or more extensive decompiler type recovery. Malcat supports custom binary structures; automatic decompiler type propagation is a separate capability. Choose around those concrete requirements and try representative samples.
Which Malcat product should I choose?
Malcat Desktop supports interactive investigations. Malcat Logos provides an on-premise, LLM-driven pipeline with prompts, model choice, dual reports and Desktop handoff. Malcat OEM covers integration of the engine into your own products and services.
Can my analysis stay local?
Desktop analyses files locally, and Logos is deployed on-premise. Network use depends on the features and models you enable: online Kesakode and threat-intelligence services make remote requests, and a remote LLM processes the inputs sent to it. Logos also supports local models.
Can an agent work without unrestricted shell or Python execution?
Malcat's MCP exposes dedicated tools for file extraction, code inspection, signatures and data transforms. It does not provide an unrestricted shell or Python execution tool. An optional, very-restricted Python byte transform can be enabled for custom decoding; it is disabled by default.
These restrictions describe Malcat's MCP interface. The tools available elsewhere in your agent's environment are controlled by your application or MCP client configuration.
