PROTECTIVE ASSESSMENTS BUILT BY THOSE WHO KNOW HOW TO BREAK IT
The perimeter no longer exists. Your applications are deployed on devices you don’t control, in environments you don’t master, in the hands of people whose intentions you cannot verify. The only protection that matters is the one that travels with your code — and that holds on its own, with no infrastructure, no network, no monitoring.
QShield is not the product of a conventional security vendor. It was born from the same offensive research that powers our Red Team teams and our vulnerability researchers. Our experts know exactly how an attacker would go about breaking your protection — because they are the very people who attack protections to assess their strength.
TECHNICAL PROTECTION EXPERTISE
Advanced obfuscation
VM obfuscation, control-flow flattening, opaque predicates — the code becomes structurally unintelligible to any static or dynamic analysis tool.
Anti-tamper & anti-debug
Runtime integrity, detection of analysis environments, dynamic checksums — the code detects and reacts to any attempt at manipulation or instrumentation.
White-box cryptography
Cryptographic implementations resistant to key extraction in a hostile execution environment — with no HSM, no server-side infrastructure.
MBA obfuscation
Mixed Boolean-Arithmetic transformations — the mathematical foundation of the obfuscations most resistant to automated simplification.
Secure compilation (LLVM)
Compiler-level transformation passes integrated into the build pipeline — transparent, reproducible protection maintainable by dev teams.
Binary protection
Applied directly at the binary level — no source-code access required, no change to observable behavior, no performance degradation.
FOUNDING SKILLS
Offensive reverse engineering
Mastery of attack to design protections that genuinely resist — not an automated tool, but a determined human expert.
Advanced exploitation
Real-condition testing by the internal offensive team — protection is battle-tested with the same tools used in Red Team engagements.
Program analysis
Modeling of control and data flow to build precise protections, targeted at the genuinely sensitive areas of the code.
Applied cryptography
Design of extraction-resistant schemes, implementation audit, validation of the robustness of the primitives used in QShield.
Software engineering
Integration of QShield into CI/CD pipelines and build processes — Security by Design, support for development teams.
Math / Arithmetic
Foundations of mixed Boolean-arithmetic transformations — a rare mastery that only teams from academic research can bring.
QUARKSLAB MOBILIZED TOOLS
Lattice-based asymmetric white-box scheme — the published scientific foundation of the cryptography embedded in QShield.
Symbolic execution to reason about target behavior and automate the discovery of attack paths.
Dynamic binary instrumentation to analyze in depth the EDR defense mechanisms in place.
Cross-platform parser and modifier of ELF, PE and MachO binaries — indispensable for firmware analysis and manipulation.
Symbolic manipulation of MBA expressions — measures the resistance of obfuscations against automated simplification tools.
Simplification of mixed arithmetic/Boolean expressions — an objective benchmark of the strength of obfuscation layers.
Bit-vector program synthesis — generation of equivalent obfuscated expressions for advanced MBA transformations.
Compliance and robustness testing of cryptographic implementations — validation during product audits.
High-performance library for lattice computations — the foundation of advanced asymmetric white-box implementations.
