polychrome-rs

Polychrome 这是一个关于如何将 payload 嵌入到计算着色器中的示例。 该 payload 经过加密，并在 GPU 上解密。 这绝不是一个完整的实现，它遗漏了关键的 OPSEC 注意事项。 用法 使用你偏好的方法生成一个 payload，我以经典的 calc.exe 作为示例。 然后使用 python 脚本 polychrome.py 生成着色器代码。 python3 polychrome.py -t both --meta -n payload 然后你应该会得到一个类似 .hlsl 的着色器文件。 要使用它，我们需要先编译它。 fxc /T cs50 /E CSMain...
