FAQ
How can I start working on reverse engineering with Apriorit?
<p>Please fill out our contact form and provide as many details about your project as you are comfortable sharing. Upon your request, we can sign an NDA.</p>
<p>Our team will contact you to discuss your goals and requirements so that we can offer the most fitting approach to fulfill your request.</p>
Can you guarantee successful results from reverse engineering research?
<p>Reverse engineering outcomes depend on multiple factors including system complexity, documentation availability, and access to devices or infrastructure. While there’s always a risk that some of your goals may not be fully achievable, Apriorit minimizes this risk by carefully assessing each request and aligning expectations with technical realities.</p>
<p>In any scenario, Apriorit ensures full transparency of the results we obtain. Even if complete reversing isn’t possible, you’ll receive detailed documentation of findings and our expert advice to guide your next steps, whether they involve continuing the reversing process or considering alternatives.</p>
Does Apriorit use AI tools in reverse engineering projects?
<p>Yes, upon a client’s request and approval, we use AI-based tools to automate certain tasks and speed up analysis for simple research. Yet, our engineers control every step, analyzing the outcomes and double-checking results and processes.</p>
<p>Human expertise is essential for accuracy and clean code. For complex or obfuscated systems, manual engineering remains key.</p>
How do you ensure accuracy when analyzing complex legacy systems?
<p>To achieve accuracy when working on legacy systems, Apriorit engineers:</p>
<ul class=apriorit-list-markers>
<li>Conduct research using an iterative approach to focus on small atomic features, examining them in detail.</li>
<li>Apply both static and dynamic reverse engineering techniques to get the most accurate behavior of a target system. Even if dynamic reverse engineering techniques bring some results, we still might miss specific cases. Static analysis helps us to comply with the original algorithm even in edge cases.</li>
<li>Continuously research the system and develop a PoC to ensure that we fully understand the system and can communicate with it.</li>
<li>Revisit already researched modules and parts of the application after some time to apply newly found mechanisms and adjust component interactions.</li>
</ul>
Can reverse engineering recover lost or incomplete source code?
<p>Yes, it can. To recover lost or incomplete source code, Apriorit reverse engineers analyze binaries, configuration files, and fragmented documentation. These actions often help us reconstruct core logic, rebuild missing parts of code, and provide you with a verified and efficient codebase.</p>
<p>Please note that Apriorit performs reverse engineering services strictly within legal boundaries and in full compliance with applicable regulations.</p>
Can reverse engineering support future system modernization?
<p>Yes. Professional reverse engineering activities can gain visibility into legacy architecture, dependencies, and risks. With such knowledge, you can create a strategic roadmap for modernization without costly guesswork.</p>
<p>However, in some cases, there’s a risk of not achieving full visibility, which is necessary for proper system modernization and to avoid extra expenses.</p>
What are the main steps in Apriorit’s reverse engineering process?
<p>Our process includes:</p>
<ul class=apriorit-list-markers>
<li>Gathering initial system information</li>
<li>Analyzing and reversing binary code</li>
<li>Extracting data and analyzing structures</li>
<li>Creating comprehensive reports with research results</li>
</ul>
Can reverse engineering help modernize legacy devices?
<p>When applied to legacy devices, reversing can reveal internal design and functionality, identify outdated components, and detect compatibility issues. This knowledge is likely to help you define whether (and to what extent) you can modernize legacy devices.</p>
<p>For the best results, Apriorit experts recommend combining reverse engineering with forward engineering practices to meet modern standards for security and scalability. Relying solely on reverse engineering may not be enough and may even lead to increased technical debt.</p>
Can reverse engineering resolve hardware–software compatibility issues?
<p>Yes. By analyzing drivers, protocols, firmware interactions, hardware, PCB, MCU, and components, we can identify mismatches and undocumented behaviors in order to adapt software for modern hardware.</p>
<p>We also recommend combining reversing with proper unit testing, thorough quality assurance efforts, and documentation updates.</p>
Can reverse engineering help avoid firmware bottlenecks that slow down development?
<p>Yes. In Apriorit’s experience, reversing helps uncover inefficient code paths and hardware limitations.</p>
<p>For example, you can find out what components should be refactored or replaced to improve system performance.</p>
