VX-API is a C++ collection of functions implementing malicious functionality to aid in malware development, maintained by vx-underground. It includes anti-debugging techniques, string hashing, compression routines, and Windows internals helpers, provided as a Visual Studio solution for malware research and red team proof-of-concepts.

Use cases

• implement anti-debugging checks in a red team tool
• hash strings for API obfuscation in malware research
• compress buffers with Xpress or LZ algorithms on Windows
• read NTSTATUS and TEB error information in C++
• build malware proof-of-concepts for defensive research
• study Windows internals techniques used by malware

When to choose

• you are doing malware research or writing proof-of-concept malware for study
• you need ready-made Windows anti-analysis and obfuscation primitives
• you want to understand techniques used in real-world malware

When to avoid

• you are building legitimate production software
• you need a supported, audited security library
• your target platform is not Windows
