An Account of the Estonian Internet War

About a year ago after coming back from Estonia, I promised I'd send in an account of the Estonian "war". A few months ago I wrote an article for the Georgetown Journal of International Affairs, covering the story of what happened there. This is the "war" that made politicians aware of cyber security and entire countries scared, NATO to "respond" and the US to send in "help". It deserved a better understanding for that alone, whatever actually happened there. more

The Future of Cyber Warfare

Every now and then I get emails from readers of my blog. I mostly reply to them in private, but I recently got one question where I thought my reply might be of general interest. I took the liberty of editing the question somewhat, but in essence it was: "If you have any insight you can share with my class on cyber warfare and security, I would be delighted on hearing it." In general, I think that it's an obvious conclusion that both offensive and defensive actions with regard to national telecommunications infrastructure is becoming an integral part of a nations security assessments.... more

VoIP/IP Telephony in Estonia: Disrupted by Botnets?

With my post earlier this month about the possibility of SIP botnets [also featured here on CircleID], I've had a number of people asking about more information and wondering about the possible impacts. And while I will write more on botnets in general, as far as the potential impact of "botnets" in general, one need only look over at the current situation in Estonia... Now, perhaps Russia is behind the attack... perhaps not. There are obviously much larger political issues going on between the two states. more

Ready or Not… Here Come the IRC-Controlled SIP/VoIP Attack Bots and Botnets!

A story... ZZZ Telemarketing (not a real name) is locked in a heated fight with their bitter rival, YYY Telemarketing (also not a real name), to win a very large lead generation contract with Customer X. Customer X has decided to run a test pitting the two companies against each other for a week to see who can generate the most leads. The ZZZ CEO has said to his staff that it is "do or die" for the company. If they fail to win the contract, they will have to shut down -- they need to do "whatever it takes" to win over YYY. A ZZZ staffer discovers that part of why YYY has consistently underbid them is because they are using SIP trunks to reduce their PSTN connection costs. But the staffer also discovers that YYY is using very cheap voice service providers who run over the public Internet with no security... more

Phishing: Competing on Security

The UK today is one of the main attack targets by phishing organized crime groups, globally. Phishing damages will amount to about two billions USD in 2006 worldwide -- not counting risk management measures such as preventative measures, counter-measures, incident response and PR damages. In most cases, phishing is caused by the fault of the users, either by entering the wrong web page, not keeping their computers secure or falling for cheap scams. Often this is due to lack of awareness or ability in the realm of Internet use rather than incompetence by the users... more

Mitigating Spoofed Attacks Using IPv6 Address Space

Timothy D. Morgan's recent paper titled, "IPv6 Address Cookies", seeks to apply the fundamental shift in resource availability brought about by the vastly increased Internet address space in IPv6 to develop a novel, lower cost solution to mitigating spoofed attacks. "Spoofed denial of service attacks have plagued the Internet for a number of years, and show no signs of abating. Research into mitigation techniques has apparently not led to a financially viable solution, and new attacks have been discovered in the wild without being widely anticipated". The following provides an introduction to this paper. more

Examining Two Well-Known Attacks on VoIP

VoIP is here to stay. In fact many incumbent telecommunication carriers have started offering VoIP service for sometime and several new VoIP service providers have emerged. Aside from issues such as quality of service, the aspect of security, or lack thereof, is misunderstood by some of the VoIP service providers. This purpose of this article is to discuss two of the most well known attacks that can be carried out in current VoIP deployments. more

Creating a Police State From the Ashes of the Internet

Former CIA Director, George J. Tenet recently called for measures to safeguard the United States against internet-enabled attacks. "I know that these actions will be controversial in this age when we still think the Internet is a free and open society with no control or accountability, but ultimately the Wild West must give way to governance and control." Mr. Tenet seems about as confused about the internet as the ITU... more
