Penetration testing of embedded software

We will find hidden vulnerabilities at the heart of your industrial devices before they become a gateway to take control of your entire infrastructure. Our reverse engineering and hardware analysis specialists will examine the firmware of your devices in search of vulnerabilities that not even their manufacturer knows about.

Identification of undocumented vulnerabilities (0-day)


Are you 100% sure what’s really in the software of the devices your business depends on?

You secure your networks and servers, but what about the software that controls the devices themselves? Firmware is often a “black box” whose contents and real security no one verifies. You trust the manufacturer’s declarations, but that’s where the most dangerous vulnerabilities can hide.

More than 80% of vulnerabilities in industrial equipment originate in firmware.

True story: how a hidden function in a PLC stopped a wastewater treatment plant

The critical infrastructure operator was using PLCs from a leading manufacturer. The company felt secure – the OT network was isolated, and regular network scans showed no problems.

However, a group of hackers, after purchasing an identical controller on an auction portal and conducting a detailed analysis of its firmware, discovered a hidden, undocumented service function. Using it, they were able to remotely and invisibly issue a command that disabled all the controllers in the facility, invisible to the monitoring systems.

The attack did not exploit any known vulnerability, and bypassed all network security. The risk was at the heart of the device – its firmware. Network security is one thing, but if the device itself has a built-in backdoor, all other protections lose their importance.


Our solution: we look under the hood of your devices

Our firmware penetration testing is a highly specialized service that goes where standard audits don’t go. Instead of testing a device from the outside, we analyze its DNA – the software that controls it. We disassemble, decompile and uncover the secrets stored in the code.

Our approach is based on 3 pillars:

Reverse engineering and firmware extraction

We acquire firmware directly from the physical memory of the device, using specialized tools (JTAG, UART) to analyze the binary code.

Static and dynamic code analysis

We analyze decompiled code for bugs, hidden functions, buried keys, weak algorithms and vulnerabilities in protocols.

Hardware and interface analysis

We study the physical interfaces of the device, capture electrical signals and radio communications (Wi-Fi, Bluetooth, LoRaWAN).


Our laboratory testing process in 5 steps

Each firmware analysis is a unique research project conducted in a secure laboratory environment.

Step 1

Target definition and device acquisition

Together we determine the purpose of the analysis. You provide us with a physical device, which becomes the object of our study.

Step 2

Reverse engineering and software analysis

Our experts carry out the firmware extraction and decompilation process in our specialized laboratory.

Step 3

Identification and exploitation of vulnerabilities

All vulnerabilities found are verified. We create dedicated exploits (Proof of Concept) to confirm the reality of the threat.

Step 4

Development of a detailed technical report

You get a highly specialized report describing each vulnerability found, its impact and recommendations for remediation at the code level.

Step 5

Presentation of results to the R&D team

We discuss the results with your technical team, providing unique insights into the inner workings and security of your equipment.


What does your business gain? Knowledge that no one else has

An investment in firmware analysis is an investment in the deepest possible level of security.

Discovery of vulnerabilities undetectable to others

Find zero-day vulnerabilities and hidden back doors in devices that are the foundation of your infrastructure or your flagship product.

Realistic verification of supply chain security

Verify the actual safety of the devices you buy from third-party suppliers. Don’t trust the manufacturer’s marketing claims – verify them.

Strengthen the security of your own product

Before you release your product to the market, make sure its software is resilient. Protect your brand, your reputation and your customers.

Gain unique knowledge of the systems you own

Understand how your key devices really work, what data they process, what hidden functions they have and what real risks they pose.

Stop trusting that your devices are safe. Start verifying it.
