seesaw's Introduction

Seesaw

基于Netlink Socket的进程监控,主动检测进程打开FD,发现并处理反弹Shell行为。

思路

1)监听Netlink Socket,实时获取进程EXEC事件。

2)检查进程启动打开的FD,如果为Shell进程,打开了Socket而未使用/dev/tty、/dev/pts/n、/dev/ptmx等终端,则确认为反弹Shell。

3)保留必要证据后杀掉异常Shell进程。

系统兼容性

所有内核支持Netlink通信机制的操作系统。

Dependency

依赖于https://github.com/dbrandt/proc_events项目,用于监听Netlink Socket。
