Memcache 反射攻击脚本

[Srar]

昨天(2018-03-02)了解到很多国人 vps 商都遭到了 memcache 反射攻击.

cloudflare 前几天也对这类反射攻击做出了通告.

所以就花了几小时做了一个 memcache 反射攻击脚本蹭一波热度.

Github: https://github.com/Srar/MemcacheDos

脚本需要伪造 IP, 大部分机房已经做了检测. 部分运营商已经在路由做 ACL 直接丢弃 11211 UDP 包.

[gdtv]

弱弱问一下，是不是修改默认的端口就可以从一定程度上防止被攻击？

[ipoh]

@gdtv 只监听 127.0.0.1 或者禁 udp

[Srar]

@litter123 nodejs 版本太老了

[litter123]

@Srar 确实是这样的，没想到 apt-get 的 nodejs 版本这么老，v0.10.....

[robinchina]

memcache 本身不需要密码，禁止外网访问 11211 端口····

[zjcqoo]

觉得大量发包的程序用 C 实现是最简单优雅高效的。

[Srar]

@zjcqoo 没错 不过我平时都在写 ts 所以用 ts 实现了
