So these certs are SSL capable certificates, which chain to a browser 
trusted PKI. If someone captured one of the certs, and then compromised 
the 1024 bit key, they could masquerade as any hostname these certs 

That risk would be mitigated if there were no hostname in the CN or in 
the Subject Alt Name. It's probably likely the case that there isn't. Do 
you know Rick?
