Seeking Amazon EC2 abuse contact

Tue Apr 20 22:19:41 UTC 2010

Just a follow-up: Amazon posted a response at
https://aws.amazon.com/security/ which discusses the issue and what they're
doing to improve things.

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.

Hello Erik,

Do you care to share the IP address? 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,
