MHN蜜罐系统建设

0x00  MHN蜜罐介绍

MHN（Modern Honey Network）：开源蜜罐，简化蜜罐的部署，同时便于收集和统计蜜罐的数据。用ThreatStream来部署，数据存储在MOngoDB中，安装了入侵检测系统的部署传感器Snort、Kippo、Conpot和Dionaea。收集的信息可以通过Web接口进行展示。据官方说法，目前经测试支持部署MHN服务器的系统有Ubuntu 14.04, Ubuntu 16.04, Centos 6.9

0x02 MHN架构

0x03  MHN安装与使用

1.Ubuntu安装MHN管理端

# 操作系统：ubuntu16.04系统更新和自动化脚本安装

sudo apt update

sudo apt upgrade -y 

sudo apt-get install git -y

cd /opt

sudo git clone https://github.com/threatstream/mhn.git

cd mhn /

sudo ./install.sh

# 配置服务器信息，这里的邮箱与密码就是安装完成后的Web后台密码

Do you wish to run in Debug mode?: y/n n

Superuser email: root@backlion.org

Superuser password: (again):

Server base url ["http://155.138.147.248"]:     

Honeymap url [":3000"]: http://155.138.147.248:3000

Mail server address ["localhost"]:

Mail server port []:

Use TLS for email?: y/n n

Use SSL for email?: y/n n

Mail server username [""]:

Mail server password [""]:

Mail default sender [""]:

Path for log file ["/var/log/mhn/mhn.log"]:

Would you like to integrate with Splunk? (y/n)n 

Would you like to install ELK? (y/n)n

# 配置splunk与ELK，我这里选择不配置

2.MHN配置

2.1 agent部署蜜罐

在Deploy选项中，选择我们需要部署的蜜罐类型，复制部署脚本进行安装。

如部署conpot蜜罐,在其系统中执行以下脚本:

wget "http://155.138.147.248/api/script/?text=true&script_id=15" -O deploy.sh && sudo bash deploy.sh http://155.138.147.248 lfDWqAN

2.2 集成Splunk与ArcSight

Splunk

cd /opt/mhn/scripts/

sudo ./install_hpfeeds-logger-splunk.sh

sudo  ./install_splunk_universalforwarder.sh

tail -f /var/log/mhn/mhn-splunk.log

这会将事件作为值记录到/var/log/mhn-splunk.log。SplunkUniveralForwarder应该监视此日志

Arcsight

cd /opt/mhn/scripts/

sudo ./install_hpfeeds-logger-arcsight.sh
tail -f /var/log/mhn/mhn-arcsight.log

2.3禁止数据上报

MHN Server会默认将分析数据上报给Anomali，如果需要禁用此配置，运行如下命令：

cd mhn/scripts/
sudo ./disable_collector.sh

3.利用MHN部署蜜罐

SSH蜜罐测试

# 蜜罐部署机器：155.138.151.176

# 部署蜜罐：dionaea
wget
"http://155.138.147.248/api/script/?text=true&script_id=4" -O
deploy.sh && sudo bash deploy.sh http://155.138.147.248 lfDWqANT

# 尝试暴力破解攻击
hydra -l root -P password.txt mssql://155.138.151.176

4.界面功能展示

1.如下图界面展示了攻击者的源IP地址以及目的端口和所属协议以及蜜罐类型等攻击报告信息。

2.如下图列出了攻击载荷报告信息（传感器，源IP地址，目的端口等信息）

3.可以看到下图列出了已安装的agent传感器

4.下图分别列出攻击者TOP的用户名和密码字典等展示图

5.打开以下连接地址可以看到实时的攻击图（honeymap)

0x05 系统排错以及安全设置

1.查看系统运行状态

root@mhn:/opt/mhn/scripts# sudo /etc/init.d/nginx status   #查看nginx状态

 * nginx is running       

root@mhn:/opt/mhn/scripts# sudo /etc/init.d/supervisor status    #查看supervisor 状态

 is running

root@mhn:/opt/mhn/scripts#sudo supervisorctl status  #查看所有蜜罐系统组件运行状态

geoloc                           RUNNING    pid , uptime ::

honeymap                         RUNNING    pid , uptime ::

hpfeeds-broker                   RUNNING    pid , uptime ::

mhn-celery-beat                  RUNNING    pid , uptime ::

mhn-celery-worker                RUNNING    pid , uptime ::

mhn-collector                    RUNNING    pid ,  uptime ::

mhn-uwsgi                        RUNNING    pid , uptime ::

mnemosyne                        RUNNING    pid , uptime ::

root@mhn:/opt/mhn/scripts#sudo supervisorctl restart all   #重启所有蜜罐系组件系统命令

正常情况各服务的状态如下：

geoloc                           RUNNING    pid , uptime ::

honeymap                         RUNNING    pid , uptime ::

hpfeeds-broker                   RUNNING    pid , uptime ::

mhn-celery-beat                  RUNNING    pid , uptime ::

mhn-celery-worker                RUNNING    pid , uptime ::

mhn-collector                    RUNNING    pid ,  uptime ::

mhn-uwsgi                        RUNNING    pid , uptime ::

mnemosyne                        RUNNING    pid , uptime ::

2.honeymap 的状态为FATAL解决方法

先删除旧版本的golang

sudo rm -rf /usr/bin/go

sudo apt-get remove golang-go

sudo apt-get remove --auto-remove golang-go

安装golang，如果apt-get install golang安装，后面会因为golang版本低而报错，所以直接下载编译后的包

wget https://storage.googleapis.com/golang/go1.9.linux-amd64.tar.gz

解压，然后进行以下配置

sudo tar -xzf go1..linux-amd64.tar.gz -C /usr//local/  //注意包名要改和自己一样的

导入环境变量：

export GOROOT=/usr/local/go

export GOARCH=amd64

export GOOS=linux

export GOBIN=$GOROOT/bin/

export GOTOOLS=$GOROOT/pkg/tool/

export PATH=$GOBIN:$GOTOOLS:$PATH

安装依赖插件net并重新启动所有蜜罐系统组件

cd /opt/honeymap/server

export GOPATH=/opt/honeymap/server

mkdir -p $GOPATH/src/golang.org/x/
cd $GOPATH/src/golang.org/x/
git clone https://github.com/golang/net.git net
go install net

sudo supervisorctl restart all

3.mhn-celery-worker的状态为FATAL解决方法

cd /var/log/mhn/

sudo chmod  mhn.log

sudo supervisorctl start mhn-celery-worker

如果还不行

cd /var/log/mhn/  #查看celery-worker的错误日志

tail -f mhn-celery-worker.err

提示的具体错误内容如下

worker.err supervisor: couldn't chdir to /root/mhn/server: EACCES supervisor: child process was not spawned）

改变root跟目录权限

chmod  -R /root  # 改下权限

4.手动密码重置

如果基于电子邮件的密码重置不适合您，这是另一种方法。

# cd /opt/mhn/server/server/

#apt install sqlite3

# sqlite3 mhn.db

SQLite version 3.7. -- ::

Enter ".help" for instructions

Enter SQL statements terminated with a ";"

sqlite> select * from user;

|USERNAME@SITE.com|sklfdjhkasdlfhklsadhfklasdhfkldsahklsd||

sqlite>.quit

$ cd /opt/mhn/server/

$ source env/bin/activate

$ cd server

$ python manual_password_reset.py

Enter email address: YOUR_USER@YOUR_SITE.com

Enter new password:

Enter new password (again):

user found, updating password

5.网络排查

$ sudo netstat -luntp  #查看网络端口开放情况

6.设置通过HTTPS访问MHN以及端口开放安全

将生成的SSL密钥文件复制到/etc/ssl/private/

将下面的配置复制到/etc/nginx/sites-enabled/

/etc/nginx/sites-enabled/mhn-https

server {

    listen               ;

    listen               ssl;

    server_name         _;

    ssl_certificate     /etc/ssl/private/mhn.pem;

    ssl_certificate_key /etc/ssl/private/mhn-priv.key;

    if ($ssl_protocol = "") {

        rewrite ^ https://$host$request_uri? permanent;

    }

    location / {

        try_files $uri @mhnserver;

    }

    root /opt/www;

    location @mhnserver {

      include uwsgi_params;

      uwsgi_pass unix:/tmp/uwsgi.sock;

    }

    location  /static {

      alias /opt/mhn/server/mhn/static;

    }

}

/etc/nginx/sites-enabled/honeymap-https

map $http_upgrade $connection_upgrade {

             default upgrade;

             ''      close;

}

server {

             listen    ssl;

             ssl_certificate     /etc/ssl/private/mhn.pem;

             ssl_certificate_key /etc/ssl/private/mhn-priv.key;

             root /opt/honeymap/client;

             index index.html index.htm;

             server_name _;

             location / {

                          try_files $uri $uri/ /index.html;

             }

             location /data/ {

                          proxy_pass http://localhost:3000;

                          proxy_http_version 1.1;

                          proxy_set_header Upgrade $http_upgrade;

                          proxy_set_header Connection $connection_upgrade;

             }

}

/etc/nginx/sites-available/splunk-https

map $http_upgrade $connection_upgrade {

        default upgrade;

        ''      close;

}

server {

        listen    ssl;

        ssl_certificate     /etc/ssl/private/mhn.pem;

        ssl_certificate_key /etc/ssl/private/mhn-priv.key;

        root /tmp;

        index index.html index.htm;

        server_name _;

        location / {

                proxy_pass http://localhost:8000;

                proxy_http_version 1.1;

                proxy_set_header Upgrade $http_upgrade;

                proxy_set_header Connection $connection_upgrade;

        }

}

需要启用以下端口并允许MHN服务器上的防火墙规则运行，所有其他端口都可以被阻止。

TCP：443 TCP：3000

7.备份数据

在MHN服务器上进行备份数据

sudo su -

supervisorctl stop all

mongodump  --db hpfeeds

mongodump  --db mnemosyne

tar zcvf mhn-backup.tar.gz dump /opt/mhn/server/mhn.db

supervisorctl start all

复制mhn-backup.tar.gz安全的地方

8.数据恢复

使用install.sh进行安装MHN ，然后将mhn-backup.tar.gz复制到/tmp/目录下并运行以下命

sudo su -

supervisorctl stop all

cd /tmp

tar zxvf mhn-backup.tar.gz

cp /opt/mhn/server/mhn.db /opt/mhn/server/mhn.db

service mongod start

dump.sh脚本：

for FILE in dump/mnemosyne/*.bson;

do

    mongorestore --drop --db mnemosyne "$FILE"

done

for FILE in dump/hpfeeds/*.bson;

do

    mongorestore --drop --db hpfeeds "$FILE"

done

supervisorctl start all

0x06 总结

使用

• 蜜罐可以存在于各种场景之中（机房、内网、云环境）；
• 蜜罐产品的思考应该是在防火墙、入侵检测之后，属于提高企业安全水平的辅助产品；
• 蜜罐主要部署在企业内网，起到预警与了解攻击中入侵的情况的作用，如：发现员工PC中毒对内网的入侵、转移攻击者注意力等等；
• 蜜罐不能设置的太过简单，也不能设置太过复杂；

优点

• 内置集成大量的蜜罐系统，且提供一键部署蜜罐的方式；
• 支持蜜罐攻击效果图展示，与ArcSight或Splunk集成友好；

缺点

• 部署时间需要很长时间（不算缺点吧，网速给力情况下不存在这个问题）；
• 不支持对蜜罐的集中管理；
