Submission + - SIP Attacks From Amazon EC2 Going Unaddressed 1
mjgraves writes: Over the past week a number of IP-PBX systems have been suffering SIP attacks from hosts in the Amazon EC2 cloud. There have been at least a dozen known attacks reported to Amazon, who have been surprisingly quiet about the matter. The issue has been well documented by one of the people suffering the attack at his blog site http://www.voiptechchat.com/voip/457/amazon-ec2-sip-brute-force-attacks-on-rise/
The matter also came under discussion on the April 16th issue of the VoIP Users Conference. A podcast of that session can be found here: http://www.voipusersconference.org/2010/amazon-ec2-flood-attacks/
Amazon appears to have gone silent on the matter even as the attacks remain ongoing. This is completely irresponsible behavior from a such a hosting company, who should be acting to take down the attacker in their midst.
