[Bro] Can Bro detect some attacks against Microsoft OS vulnerability?

[北村 真一]

Hello, all.

I have a question about Bro rules.
Does Bro have some rules of detecting attacks against Microsoft OS
vulnerability?

I attempted to attack against MS03-026 vulnerability of Windows_XP_SP1
on the VMware using Dcom attack code.
Though, Bro does not detect this attack.

If you have a lot of infomation relating to these problem, could you
give me advice?

Thank you.
