AlushPacker

AlushPacker is a Windows utility for packing native Portable Executable (.exe) files for in-memory execution. Its builder compresses the executable with LZAV and encrypts it using a custom XTEA implementation. At runtime, a reflective loader decrypts and decompresses the embedded program, then loads it from memory without disk I/O or use of the Windows loader. The project says this can make static analysis and reverse engineering with tools such as IDA Pro or Ghidra more difficult. Listed support covers x86 and x64 executables, including native console, GUI, and legacy EXE files. The loader can resolve normal and delay-loaded imports by name or ordinal, handle relocations, register SEH, and run TLS callbacks. An optional -l key option makes the output request a password before execution. The release ZIP contains packer.exe for creating packed executables. AlushPacker is free and its source code is under the MIT License, which permits use, modification, distribution, sublicensing, and sale subject to its conditions. The project invites code improvements, bug reports, and feature suggestions for maintainer review.
