Awesome GitHub RepositoriesConstraint-Based Value Analysis
Static analysis techniques that solve systems of constraints to track variable ranges and pointer offsets.
Distinct from Range Constraints: Candidates focus on runtime value enforcement or random test data constraints, not static program analysis via constraint solving.

4,251Vezi pe GitHubMythril este un analizor de securitate pentru smart contracte în Ethereum Virtual Machine care utilizează execuția simbolică pentru a identifica vulnerabilitățile în bytecode înainte de deployment. Funcționează ca un scaner de vulnerabilități și auditor formal, tratând input-urile programului ca simboluri matematice pentru a demonstra prezența bug-urilor în logica contractului. Instrumentul efectuează o analiză la nivel de bytecode pentru a detecta defecte care pot fi ascunse de compilatoarele de nivel înalt. Acesta integrează SMT solvers pentru a determina dacă stările specifice de vulnerabilitate sunt accesibile și compară urmele de execuție simbolică cu o bibliotecă de semnături cunoscute ale defectelor de securitate. Proiectul acoperă o gamă largă de capabilități de analiză a securității, inclusiv detectarea vulnerabilităților blockchain, auditarea formală a logicii contractelor și testarea automată a securității. De asemenea, oferă integrare pentru workflow-urile Git pentru a valida codul ca parte a procesului de commit.
Integrates SMT solvers to mathematically prove the reachability of specific vulnerability states.

4,202Vezi pe GitHubTriton is a dynamic binary analysis framework designed to automate reverse engineering. It functions as a multi-architecture CPU emulator, an SMT-based symbolic execution engine, and a dynamic taint analysis tool. The framework translates raw machine instructions into abstract syntax trees, allowing it to represent binary program logic as a structured intermediate representation. This allows the system to map multiple hardware instruction sets to a single analysis framework and translate machine instructions into mathematical formulas for solving constraints. Its capabilities cover the simul

3,115Vezi pe GitHubIkos is a formal verification suite and static analysis framework designed to prove the absence of undefined behaviors and runtime errors in C and C++ source code. It functions as an abstract interpretation tool that approximates program execution to identify potential crashes and software defects. The system utilizes a compiler front-end to translate source code into a specialized abstract representation. This process decouples language parsing from the analysis logic, allowing the framework to perform deep program analysis via a formal verification system. The toolkit covers several analys
Tracks variable ranges and pointer offsets by solving systems of constraints during program traversal.

2,943Vezi pe GitHubKani is a formal verification tool and model checker for Rust. It functions as a bit-precise static analyzer that mathematically proves the correctness and memory safety of code by exhaustively analyzing program states to identify undefined behavior, panics, and logic errors. The tool identifies bugs by producing concrete counterexamples when program assertions or safety contracts are violated. It enables the definition of function contracts through preconditions and postconditions to verify that inputs and outputs match expected behavior. The system provides capabilities for Rust program an

1,684Vezi pe GitHubSVF is an open-source static program analysis framework and points-to analysis library that tracks memory references, variable aliases, and data dependencies across whole programs. The platform translates compiled intermediate code formats into unified internal representations, constructing constraint graphs, call graphs, and control-flow graphs to model interprocedural execution behavior and memory state. The framework incorporates specialized engines for flow-sensitive, flow-insensitive, and context-sensitive pointer analysis alongside sparse value-flow graph generation. It features memory
Builds constraint graphs for inclusion-based pointer analysis by iteratively resolving and adding copy edges.
