J.D. Falk Award

This morning M³AAWG announced the creation of the J.D. Falk award to recognize and honor people like J.D. who work to make the Internet safer for all users... J.D. was a legend in the abuse prevention world when I first started learning about spam and abuse prevention back in the late 90's. more

IP Addresses and Privacy Sensitive Data - A Level Playing Field Needed

Reading Peter Olthoorn's book on Google (a link is found here), I ran into a passage on IP addresses. Where Google states that it does not see an IP address as privacy sensitive. An IP address could be used by more than one person, it claims. The Article 29 Working Party, the EU privacy commissioners, states that it is privacy sensitive as a unique identifier of a private person. It got me wondering whether it is this simple. Here is a blog post meant to give some food for thought and debate. I invite you to think about the question 'how private is an IP address'? more

High Performance DNS Needs High Performance Security

There's been a lot of emphasis on DNS performance lately because faster DNS contributes directly to a better user experience. There's an interesting flipside to DNS performance though, higher performance DNS servers may be better targets for cache poisoning attacks. Faster servers give attackers more opportunities to insert fake entries into the DNS - speed can kill (or at least inflict a nasty wound!) so it's important to understand the security implications if you're looking to upgrade DNS performance. more

The Sportsmanship of Cyber-warfare

As a bit of a history buff I can't avoid a slight tingling of déjà vu every time I read some new story commenting upon the ethics, morality and legality of cyber-warfare/cyber-espionage/cyberwar/cyber-attack/cyber-whatever. All this rhetoric about Stuxnet, Flame, and other nation-state cyber-attack tools, combined with the parade of newly acknowledged cyber-warfare capabilities and units within the armed services of countries around the globe, brings to the fore so many parallels... Call me a cynic if you will, but when the parallels in history are so evident, we'd be crazy to ignore them. more

WCIT Prep Dénoument?

I'm sitting in the Popov Room of the ITU Tower in Geneva, the room is quiet, the atmosphere placid, chairs are empty. The final meeting of the CWG WCIT prep WG has just concluded its work and the chair will be reporting to the Council the results of our work. I find myself strangely calm and looking forward to my next week, to be spent in Prague... Should you choose to read through the documents, and they are lengthy at approximately 375 pages, you might think that a number of the proposals were directed at the Internet. more

Flame Virus Was Developed by U.S., Israel to Slow Iranian Nuclear Efforts, According to Officials

The United States and Israel are reported to be responsible for developing the Flame virus aimed at collecting intelligence in preparation for cyber-sabotage aimed at slowing Iran's ability to develop a nuclear weapon, according to Western officials with knowledge of the effort. According the Washington Post, "[t]he massive piece of malware secretly mapped and monitored Iran's computer networks, sending back a steady stream of intelligence to prepare for a cyberwarfare campaign, according to the officials." more

Romney Emails Hacked

US presidential candidate Mitt Romney will likely be reconsidering his email passwords after his online email account was reportedly hacked. A hacker claims to have accessed Romney's Hotmail and Dropbox accounts after guessing the answer to the Republican candidate's 'favourite pet' security question. It's suspected Romney used the same password for more than one account. more

According to the Department of Homeland Security, Cybercrime Is a Bigger Threat Than Terrorism

An article in Forbes the other day reports on US Secretary of Homeland Security Janet Napolitano's comments that 'cybercrime represents the "greatest threat and actual activity that we have seen aimed at the west and at the United States" in addition to "or other than Al Qaeda and Al Qaeda-related groups."' ..."Napolitano cited a study commissioned by Symantec that put the total worldwide cost of cybercrime at $388 billion -- higher than the global market for heroin, cocaine and marijuana combined." more

Restricting Anti-Virus Won’t Work

In a blog post, Stewart Baker proposed restricting access to sophisticated anti-virus software as a way to limit the development of sophisticated malware. It won't work, for many different and independent reasons. To understand why, though, it's necessary to understand how AV programs work. The most important technology used today is the "signature" - a set of patterns of bytes - of each virus. Every commercial AV program on the market operates on a subscription model... more

Best Practices for Implementing IPv6 and Avoiding Traffic Exposures

There has been a lot of discussion lately about the potential for IPv6 to create security issues. While there are definitely some security risks of IPv6 deployment, a carefully considered implementation plan can help mitigate against security risks. As we approach World IPv6 Launch tomorrow, I thought it prudent to share the below described incident that iDefense recently observed. more

Flame On!

Here we go again; another instance of really sophisticated spyware has been reported, a system that is "so complex and sophisticated that it's probably an advanced cyber-weapon unleashed by a wealthy country to wage a protracted espionage campaign on Iran". I won't get into the debate about whether or not it's really more impressive than Stuxnet, whether or not it's groundbreaking, or whether or not Israel launched it; let it suffice to say that there are dissenting views. I'm more interested in the implications. more

A Closer Look at the Flame/Flamer/sKyWIper Malware

The world is abuzz this week with some flaming malware - well "Flame" is the family name if you want to be precise. The malware package itself is considerably larger than what you'll typically bump into on average, but the interest it is garnering with the media and antivirus vendors has more to do with the kinds of victims that have sprung up - victims mostly in the Middle East, including Iran - and a couple of vendors claiming the malware as being related to Stuxnet and Duku. more

National Infrastructure Crisis: Improving Distribution Metrics

Not understanding the need for a newer, more economically sound, eco-friendly, and secure utilities infrastructure can be a (socio-economic disaster in the making), if top leaders of U.S. industry and government do not seek a solution to our historically aged telecommunications, power, and water delivery systems. The legacy systems in place are expensive, un-reliable, publically unsafe, and vulnerable to sabotage on both a large and small scale. more

The Antivirus Uncertainty Principle

The antivirus industry has been trying to deal with false positive detection issues for a long, long time - and it's not going to be fixed anytime soon. To better understand why, the physicist in me draws an analogy with Heisenberg's Uncertainty Principle - where, in its simplest distillation, the better you know where an atom is, the less likely you'll know it's momentum (and vice versa) - aka the "observer effect". more

Google Notifying Half a Million Users Affected By DNSChanger

Google has announced that it has started undertaking an effort to notify roughly half a million people whose computers or home routers are infected with a well-publicized form of malware known as DNSChanger. "After successfully alerting a million users last summer to a different type of malware, we've replicated this method and have started showing warnings via a special message that will appear at the top of the Google search results page for users with affected devices." more
