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 [25]: 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 31443, uptime 0:00:12 honeymap RUNNING pid 30826, uptime 0:08:54 hpfeeds-broker RUNNING pid 10089, uptime 0:36:42 mhn-celery-beat RUNNING pid 29909, uptime 0:18:41 mhn-celery-worker RUNNING pid 29910, uptime 0:18:41 mhn-collector RUNNING pid 7872, uptime 0:18:41 mhn-uwsgi RUNNING pid 29911, uptime 0:18:41 mnemosyne RUNNING pid 28173, uptime 0:30:08 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 31443, uptime 0:00:12 honeymap RUNNING pid 30826, uptime 0:08:54 hpfeeds-broker RUNNING pid 10089, uptime 0:36:42 mhn-celery-beat RUNNING pid 29909, uptime 0:18:41 mhn-celery-worker RUNNING pid 29910, uptime 0:18:41 mhn-collector RUNNING pid 7872, uptime 0:18:41 mhn-uwsgi RUNNING pid 29911, uptime 0:18:41 mnemosyne RUNNING pid 28173, uptime 0:30:08
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 go1.9.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 777 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 777 -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 3.7.9 2011-11-01 00:52:41 Enter ".help" for instructions Enter SQL statements terminated with a ";" sqlite> select * from user; 1|USERNAME@SITE.com|sklfdjhkasdlfhklsadhfklasdhfkldsahklsd|1| 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 Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 561/sshd tcp6 0 0 :::21 :::* LISTEN 3763/dionaea tcp6 0 0 :::22 :::* LISTEN 561/sshd tcp6 0 0 :::1433 :::* LISTEN 3763/dionaea tcp6 0 0 :::443 :::* LISTEN 3763/dionaea tcp6 0 0 :::445 :::* LISTEN 3763/dionaea tcp6 0 0 :::5060 :::* LISTEN 3763/dionaea tcp6 0 0 :::5061 :::* LISTEN 3763/dionaea tcp6 0 0 :::135 :::* LISTEN 3763/dionaea tcp6 0 0 :::3306 :::* LISTEN 3763/dionaea tcp6 0 0 :::42 :::* LISTEN 3763/dionaea tcp6 0 0 :::80 :::* LISTEN 3763/dionaea udp 0 0 0.0.0.0:68 0.0.0.0:* 464/dhclient3 udp 0 0 0.0.0.0:40077 0.0.0.0:* 3763/dionaea udp6 0 0 :::5060 :::* 3763/dionaea udp6 0 0 :::69 :::* 3763/dionaea $ sudo iptables -L #查看防火墙规则状态 Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination $ sudo tcpdump -nnNN tcp port 10000 #监听tcp 10000数据通信信息 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 16:46:14.009646 IP 1.2.3.4.42873 > 5.6.6.8.10000: Flags [P.], seq 1180349317:1180349611, ack 2474834734, win 913, options [nop,nop,TS val 85084174 ecr 169636000], length 294 16:46:14.012967 IP 5.6.6.8.10000 > 1.2.3.4.42873: Flags [.], ack 294, win 162, options [nop,nop,TS val 169661444 ecr 85084174], length 0 # netstat -luntp | grep 10000 #查看端口10000的状态 tcp 0 0 0.0.0.0:10000 0.0.0.0:* LISTEN 980/python $sudo tail -f hpfeeds-broker.err #查看hpfeeds-broker错误信息 INFO:root:Auth success by mnemosyne.

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 80; listen 443 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 8443 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 8001 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；
