Syscall 7 is a software development and security analysis consulting firm located in the greater Baltimore, MD region. We specialize in firmware development, system-level software development, and software security analysis. We provide firmware and software development and consulting services at all levels of the software stack, including low level assembly, Linux internals and kernel-level development, custom network protocol development, and system-level C and C++ development on Windows, Android, Linux, FreeBSD, and other proprietary operating systems.Performed software code review, security analysis, and reverse engineering in support of expert witness testimony for technology related litigation. Reversed a Windows application to extract the secret key and key exchange algorithm used to authenticate with an embedded systems device.

Founded a collaborative, cloud-based reverse engineering platform called the Online Disassembler (ODA). Designed and developed features across the full stack of software components including Javascript/Angular/CSS on the frontend and Django/Python/C on the backend.

Analyzed critical infrastructure devices and Supervisory Control and Data Acquisition (SCADA) systems and identified software and network security vulnerabilities in these systems. Recommended techniques and methods to mitigate the risks posed by the weaknesses uncovered. Designed and developed MIPS and x86 firmware for custom, embedded devices. Developed a Linux-based IP tunneling solution using the TUN/TAP virtual network kernel devices. Developed Wireshark dissectors for custom networking protocols. Developed distributed processing frameworks based on RPC technologies. Wrote a Python utility to extract over 300 features from Windows PE executables, which were then processed by a machine learning based malware analysis platform.

Designed and developed a portable architecture for an embedded, non-multitasking kernel comprising a device driver framework, network stack, and filesystem ported to a variety of embedded platforms; Developed device drivers for UARTs, compact flash devices, and network interface controllers (both wired and wireless); Developed system-level code for exception handling and virtual memory management; Developed the VHDL firmware for a CPLD used to bootstrap a Xilinx FPGA; Developed bootloaders for a variety of platforms; Developed Wireshark/Ethereal dissectors for custom network protocols; Developed and maintained the Python-based build system used for building our cross-platform code; Used the IDA Pro disassembler on many platforms including MIPS, PowerPC, Intel x86, NIOS II, and ARM; Served as technical lead on several critical tasks; Served as supervisor of a small team of engineers;

Developed a variety of Windows and VMS-based applications in various programming languages (C, C++, C#, Visual Basic) to support the infrastructure of a flight simulation laboratory; Wrote a 1553 bus controller in C to simulate an aircraft mission computer; Integrated RADAR and FLIR image generators with aircraft avionics; Implemented a C#-based multi-platform simulation executive; Wrote a Windows DLL to transmit real-time simulation data as a PCM data stream overfiber to a telemetry processing facility;
