Amazon EC2 Flood Attacks from the Cloud

Audio : Download file (EC2Attacks.mp3)


Part of this article is an edited summary of material from VoipTechChat.com

Complaints of rampant SIP Brute Force Attacks coming from servers with Amazon EC2 IP Addresses cause many admins to simply drop all such traffic. Generally, SIP brute force attacks attempt to register various peer names to a system and/or attempt to guess passwords of known/guesses peers or endpoints. The object is theft of resources.

The complaints mentioned this weekend show an excessive amount of traffic; with some providers claiming 6GB of traffic dedicated to such attacks. Since we ourselves received an attack from an Amazon hosted server, we also reported and complained to the Amazon NOC/Abuse depts.

There are various techniques to assist with minimizing DDoS and Brute Force attacks, such as limiting access via the public internet, using strong passwords, not mapping extension name to peer/endpoint name, limiting simultaneous calls, and aggressively monitoring usage. Automatic blocking of abusive IP’s (fail2ban, blockhosts, etc.) can also assist with minimizing damage.

VOIPSA

VUC official position: EC2 abuse costs victims time and money. Amazon is 100% accountable for what their customers do with their resources and must react swiftly to complaints.

VUC 60 second rant: This week saw a new feature rolled out, the Voipusers One Minute Issue Talk (VOMIT) where all listeners are encouraged to phone in their VoIP-related rants. Call and leave yours at (518) VUC VOIP or (518) 882-8647.

Tropo Cloud-Based Communications Platform

Audio : Download file (TS-317299.mp3)

voxeologoWe welcome Jason Goecke and Dan York back to talk about some of their newest services. When “JSON” talks, ideas become reality! Check out the new Tropo API.

Tropo is a cloud communications platform that makes it easy for you to quickly add voice, instant messaging (IM), and SMS to your applications, using the programming languages and tools you already know using a web services API and JSON.

On this call we talked about the newest features in Tropo and how to get started with telephony apps in the cloud without adding new infrastructure. In fact, at least one person created a developer account and wrote a short application!

Voxeo Labs’ Jason Goecke, Jay Phillips and Dan York  join us to talk about the news:

Ok, the word is out, Voxeo Labs is born! Voxeo, provider of Unified Communications and Self-Service platforms, announced that the Tropo.com cloud telephony service source code will be made available to developers for free under open-source licenses. The new Tropo source release demonstrates that cloud computing vendors can subscribe fully to open-source ideals, and avoid the proprietary lock-in typically found in cloud services. Tropo is the first of several new open-source projects from Voxeo Labs, the innovation and open-source focused organization announced by Voxeo yesterday at OSCON.

From TheNextWeb.com : Don’t accept vendor lock ins!

Part 2 (ZipDX recording served from CloudFront):

Audio : Download file (ZipDX20090619.mp3)

We’ve tried to get people to talk about this before, but we didn’t get a deep explanation. Here’s a chance to ask Nir, who did a compelling presentation at AMOOCON on Asterisk on EC2, to clear up any of those nagging questions you might have.

Nir’s AMOOCON presentation, Dynamic Asterisk Scalability with Amazon EC2 and videos are available on the AMOOCON site. Nir’s company is Greenfield Tech.

Nir is also the author of Asterisk Gateway Interface 1.4 and 1.6 Programming

Jerry Shuman of Perssonas (@theagent) joined the call with some great input, too.
