Reverse engineering
Tracing the invisible logic inside complex software, runtimes, and game systems.
Skull Labs is an independent research organization exploring the systems beneath modern software and game ecosystems.
We work at the intersection of reverse engineering, security research, and the relentless curiosity to understand how things truly work.
Tracing the invisible logic inside complex software, runtimes, and game systems.
Reading instruction flow, compiler behavior, and the architecture between the lines.
Researching cryptography, integrity, resilience, and the future of secure ecosystems.
Beyond surface vulnerabilities, our instrumentation penetrates runtimes, compilers, hypervisors, and custom execution engines.
Tracing virtual machine privilege transitions, shadow page tables, and hardware-assisted virtualization hooks in real time.
Unraveling instruction virtualization, opaque predicates, and metamorphic packing logic down to clean intermediate representations.
Formulating and solving SAT/SMT path constraints to explore unreached execution states and hidden conditional branches.
Validating side-channel resilience, timing-attack resistance, and constant-time execution invariants across custom protocols.
“The most interesting systems reveal themselves at the edges.”
