maltrail是一款轻量级的恶意流量检测系统,其工作原理是通过采集网络中各个开源黑样本样本(包括IP、域名、URL),在待检测目标机器上捕获流量并进行恶意流量匹配,匹配成功则在其web页面上展示命中的恶意流量。
https://github.com/stamparm/maltrail
系统采用 流量–>传感器<–>服务端<–>客户端 的架构方式
传感器:负责采集网络流量,更新恶意样本,并进行匹配检测
服务端:提供web界面以及收集网络中的恶意样本流量
客户端:访问和检索恶意流量信息

Maltrail订阅网络上的各种恶意样本网站,其所有采集程序存储在$MALTRAIL_HOME/trails/feeds目录中。
用订阅源360chinad.py程序举例,代码如下

if __check__ in content
使用内容匹配字符串来验证网站内容,若匹配失败则放弃订阅
retval
为字典对象,其中key为样本主键,例如IP、URL、域名。value则是元组(样本信息,网站域名)
当我们需要添加自定义订阅源时,只需要按上述格式,类似于Java继承的方式,实现fetch()
方法,并返回retval
,将程序放入$MALTRAIL_HOME/trails/feeds目录中,在每天更新trails.csv文件时则会将自定义的恶意样数据添加进去。
Maltrail最有价值的地方不在于检测和展示,而是对IOC的收集利用,建立一套成熟的OpenIOC机制。
Maltrail数据抽取入口在$MALTRAIL_HOME/core/update.py中。

update_trails(server=None, force=False, offline=False)
该方法用于更新所有订阅源,并生成trails.csv文件
server
默认为None,输入为网络中的开源样本集url地址,则会将该url中的数据更新到trails.csv文件
force
默认为False,当设为True时,则更新全量恶意样本的数据(即内置静态列表和实时订阅源)到trails.csv文件中
offline
默认为False,当设为True时,进行离线更新,将内置静态列表更新到trails.csv文件中
有兴趣的朋友可将该方法剥离出来,采集网络上开源的恶意样本数据,建立自己的IOC库。
