Reverse
EnGineering

We have years of experience working on x86, x64, ARM, JVM's bytecode and other more. We read and write assembly code and understand how crashes happen.

We have experience dissecting patches and cracking protected binaries to figure out exactly how they work. Native binaries are handled through manual reverse engineering, debugging, and instrumentation.

Mostly through manual study, we are able to determine the functionalities provided by the binaries under examination. Using fuzzing and other dynamic techniques, we elicit unintended behaviors that could be used to subvert the security of a system.

We're passionate about reverse engineering challenges as they provide a unique opportunity to learn how things work under the hood.

Being very familiar with complex protocol designs and file formats, our team can derive formats and specifications from samples. As we've done several times, we can create interoperable implementations of protocols and parsers to be used in both offensive security and software engineering applications.

While reversing activities are tailored to the specific customer's need, we generally kick off these engagements by collecting and categorizing samples of network traffic or files. We manually study the interaction between systems using those protocols and files, and derive the underlying design. Whenever required, we build custom tools to be able to generate or parse those formats and messages. To end, we document all processes and results in a concise but precise report.
