UPX解压分析
原名：analyzing-packed-malware-with-upx-unpacker
识别并解压UPX加壳恶意软件，包括修改了魔数或头部的样本，以恢复原始可执行文件进行静态分析。适用于高熵、导入表仅有LoadLibrary/GetProcAddress，或需为Ghidra/IDA准备加壳二进制文件的场景。

内容概览
- Static analysis reveals high entropy sections and minimal imports indicating the binary is packed - PEiD, Detect It Easy, or PEStudio identifies UPX or another known packer - The import table contains only LoadLibrary and GetProcAddress (runtime import resolution typical of packed binaries) - You need to recover the original binary for proper disassembly and decompilation in Ghidra or IDA - Automated UPX decompression fails because the malware author modified UPX magic bytes or headers Do not use when dealing with custom packers, VM-based protectors (Themida, VMProtect), or samples where dynamic unpacking via debugging is more appropriate. - UPX (Ultimate Packer for eXecutables) installed (apt install upx-ucl or download from https://upx.github.io/) - Detect It Easy (DIE) for packer identification - Python 3.8+ with pefile library for manual header repair - x64dbg or x32dbg for manual …
