[Snort-users] non-standard ping messages

With the recent revelations of the Target breach, I was wondering if there is an existing rule that watches for non-standard ping messages crossing the network?  That was one of the indicators in this incident and that seems like something useful to look for anyway, so maybe there is already a rule either in VRT or ET the ruleset.  Does anyone know of an existing rule?
