Many thanks again to the large number of off-list responses. After making human contact, the issue was very promptly resolved by Amazon and a gentleman there has promised to look into the error on the abuse form as well.

So everyone could update their firewalls to block the attacks? Even only blocking known SIP ports (5060) could be a good idea. With kind regards, Mark Scholten

Michael,
I've received numerous off-list responses yesterday. Most of them were asking if I've made contact with anyone there as they were being attacked as well. One gentleman who works at AWS (but not EC2 abuse) promised to forward my e-mail to them. I've also been reading the asterisk-users list where many have reported attacks from Amazon EC2 as well over the past few days.
At one point we were seeing 197 SIP brute force attempts per second against a customer's box. The intensity in terms of bandwidth is low, but if you do the math, you can see that this isn't the point.
This morning I received an e-mail from Amazon which was basically the same as the one you received. The attack is still on-going and I've still not made contact with a human at Amazon.
Erik

Erik, We have several customers being attacked from the same EC2 instance on their network for 2 full days now. Contacted them at ec2-abuse@amazon.com and 25 hours later received a message that basically said, "Yep, we can confirm that a customer of ours is attacking you but that's their fault. We sometimes do stuff, but not in this case. Please don't block us, because the IP might be someone else later. Have a nice day". The telephone number in the WHOIS record goes to a general voicemail box for their legal department. A few of our customers who are being attacked by this same instance at EC2 have also contacted Amazon, and were told essentially the same thing. While I appreciate that they sent a response, I do not appreciate it's uselessness. Anyone over there at AWS that can do something willing to reply to me directly?
Thanks! Mike
Could someone from Amazon EC2 please contact me off-list regarding an abuse issue from one of their IPs? Alternatively, could someone please send me the contact

E-mailing the abuse e-mail listed in WHOIS per their
instructions, including all pertinent data, results in an auto-reply indicating to use a form on their site. Submitting the form results in "There has been an error while submitting your data. Please try again later." Calling their supposed NOC (as per WHOIS) results in "You have reached the legal department at Amazon...please leave a message".
Thanks
