The Problem With Wikis

Wikis have been around for a long time on the Web. It's taken a while for them to transform from geek tool to a mainstream word, but we're here now. Last week at the ICANN Meeting in Vancouver, it was fun to watch hundreds of people get introduced to Wikis and start using them, thanks to Ray King's ICANN Wiki project. In the past few days since, I've come to believe that Wikis are doomed unless they start thinking about security in a more serious way. more

Nom-Com Appoints Independent and Diverse Candidates to ICANN Leadership Positions

When 72 candidates vie for 8 positions, making tough choices are inevitable. ICANN's 2005 Nominating Committee (Nom-Com) on Friday announced the selection of a diverse and independent set of nominees for important roles in ICANN, including the Board of Directors, the Generic Names Supporting Organization (GNSO), the At-Large Advisory Council (ALAC) and the Country Code Names Supporting Organization (ccNSO). more

Survey Results Expose Widespread DNS Vulnerabilities

The Measurement Factory and Infoblox have announced results of a survey of more than 1.3 million Internet-connected, authoritative domain name system (DNS) servers around the globe. The results of the survey indicate that as many as 84 percent of Internet name servers could be vulnerable to pharming attacks, and that many exhibit other security and deployment-related vulnerabilities. The surveys consisted of several queries directed at each of a large set of external DNS servers to estimate the number of systems deployed today and determine specific configuration details. more

Abusive Anti-Anti-Spam Scheme a Dreadful Strategy

A new company called Blue Security purports to have an innovative approach to getting rid of spam. I don't think much of it. As I said to an Associated Press reporter: "It's the worst kind of vigilante approach," said John Levine, a board member with the Coalition Against Unsolicited Commercial E-mail. "Deliberate attacks against people's Web sites are illegal." more

There Is No “Spam Problem”

This month I thought I could feel smug, deploying Postfix, with greylisting (Postgrey), and the Spamhaus block list (SBL-XBL) has reduced the volume of unsolicited bulk commercial email one of our servers was delivering to our clients by 98.99%. Alas greylisting is a flawed remedy, it merely requires the spambots to act more like email servers and it will fail, and eventually they will... more

Phishing: An Interesting Twist on a Common Scam

After Two Security Assessments I Must Be Secure, Right? Imagine you are the CIO of a national financial institution and you've recently deployed a state of the art online transaction service for your customers. To make sure your company's network perimeter is secure, you executed two external security assessments and penetration tests. When the final report came in, your company was given a clean bill of health. At first, you felt relieved, and confident in your security measures. Shortly thereafter, your relief turned to concern. ...Given you're skepticism, you decide to get one more opinion. ...And the results were less than pleasing. more

Actions Required by Developing Economies Against Spam

My OECD paper on spam problems in developing economies is now linked from the OECD Anti-Spam Toolkit page, as part of section 8 of the Anti-Spam Toolkit (Outreach). This ZDNet article provides a reasonably good summary of my paper as well. I welcome comments and suggestions from CircleID readers. "Spam is a much more serious issue in developing countries as it is a heavy drain on resources that are scarcer and costlier in developing countries than elsewhere..." more

Crack the Code: That’s a Direct Challenge

I had quite an interesting experience recently. I was hired by a company to perform a vulnerability assessment and penetration test on their network. During the initial meeting, one of the key technical staff presented me with a challenge; He handed over the NTLM hash of the domain Administrator account and challenged me to decipher it. He explained that the complexity and length of the password would prevent me from deciphering it during the time allotted for the project. He was actually quite confident in my impending failure... more

New Study Revealing Behind the Scenes of Phishing Attacks

The following is an overview of the recent Honeynet Project and Research Alliance study called 'Know your Enemy:Phishing' aimed at discovering practical information on the practice of phishing. This study focuses on real world incidents based on data captured and analyzed from the UK and German Honeynet Project revealing how attackers build and use their infrastructure for Phishing based attacks. "This data has helped us to understand how phishers typically behave and some of the methods they employ to lure and trick their victims. We have learned that phishing attacks can occur very rapidly, with only limited elapsed time between the initial system intrusion and a phishing web site going online..." more

Identity Theft: Giving Away Your Personal Information

Identity theft is apparently the "in thing" these days. By media accounts, hackers and evildoers lurk everywhere trying to steal your personal information. In the past few months, one company after another is being forced to admit customer data has been lost or stolen. In many cases, they have them come forth repeatedly over the next few weeks, or even months revising the estimated number of impacted customers. To date, I don't think any have ever lowered those numbers. ...Let's consider two events that didn't make the front page of C|Net or CNN.  more
