Amazon's EC2 Security contact

Hey all, apologies for shooting this on this list, but I've had greater
success here.

Anyone have a SECURITY contact for "Amazon Web Services, Elastic Compute
Cloud, EC2" outside of the typical: whois -h whois.arin.net
$THEIRSPACE|grep "@"

I'm looking at a delicate situation here and would appreciate any
OOB/non-tech-sup-spool-box contact.
