[Bro] bro policy to identify memcached attacks/participation

We have put together some sample bro policy that might be useful in
1) memcached instances with publicly available TCP ports.
2) UDP connection attempts to 11211/udp.
3) excessive outbound traffic from an IP that has previously had an inbound
memcached 'get' request from outside the local address space.
This code is a little green, but can be used to keep an eye on your local
network as this problem evolves.
Repo can be found here:
If you have any questions please let me know and I will do what I can to
help. As well, any changes or improvements will be gladly integrated into
the code as well.
Feel free to share with anyone as this is public information.
