Reverse engineers Rust-compiled malware using IDA Pro and Ghidra. Extracts crate dependencies, handles non-null-terminated strings, and analyzes Rust-specific control flow.

由于 Rust 的跨平台编译能力、内存安全保证，以及对逆向工程师造成的复杂性，它在恶意软件开发中越来越受欢迎。Rust 二进制文件包含完整的静态链接标准库，生成的二进制文件体积较大且包含大量样板代码。主要挑战包括：非空终止字符串（Rust 使用胖指针，包含指针和长度两部分）、单态化（monomorphization）导致泛型代码重复、复杂的错误处理（Result/Option 解包链），以及不熟悉的调用约定。与 C/C++ 二进制文件相比，将 Rust 反编译为 C 代码的效果很差。Ghidra crate 提取脚本和针对 Rust 特有模式（2024-2025 年）的专项培训有助于应对这些挑战。典型的 Rust 恶意软件包括 BlackCat/ALPHV 勒索软件、Hive 勒索软件变种和 Buer Loader。
