ElfPack：用于无阶段有效负载投递的ELF二进制节段对接 亮点 有效负载捆绑机制概述：编译、链接和加载。 二进制兼容性及创建与投递机制松散耦合的有效负载。 避免节段的自动内存加载。 使用结构化节段类型。 现场通过ELF节段将有效负载（重新）附加到加载器。自带有效负载。 利用分离的预编译ELF节段进行签名规避。 通过负载生成管道进行有效负载的“路过式”附加。 创建胖有效负载二进制文件及避免使用二进制打包器的情形。 打包复杂有效负载。 有效负载混淆和密钥保护选项。 静态和动态负载加载跟踪抵抗。Binwalk和eBPF。 嵌入有效负载 通过编译和链接进行十六进制二进制包含 1...
NullSection
NullSection NullSection 是一款反逆向工具，它采用一种技术将节头覆盖为空字节。 安装 git clone https://github.com/MatheuZSecurity/NullSection cd NullSection gcc nullsection.c -o nullsection ./nullsection 优势 在任何 ELF 文件（例如 .ko rootkit）上运行 nullsection 后，如果你使用 Ghidra/IDA 来解析 ELF 函数，将不会显示任何内容——反编译器中不会有可解析的函数。即便你运行 readelf -S...
