Absolutely!  Lightning can strike just about anything and can cause damage to anything connected to it.  Most likely, however, it was not a direct strike, which probably would have vaporized the CAT5 wire.  The biggest problem with long runs of wire is an INDUCED transient from a nearby lighting strike.  In this case protective devices on the CAT5 wire can often absorb the transient and protect the equipment.
