Oh, Spammer, Where Art Thou?

A few weeks ago, I posted a piece on where individuals spammers were located in terms of sending IP. The United States was number 1, followed by China. This is in terms of total volume of spam that they send. However, a second piece of data that I did not take a look at was where all of the individual spam sites contained within the spam was located. For example, does a lot of spam sent from the United States point to spammy URLs hosted in China? more

Helping Banks Fight Phishing and Account Fraud, Whether They Like It or Not

On Wednesday, Project Honey Pot filed an unusual lawsuit against "John Does stealing money from US businesses through unauthorized electronic transfers made possible by computer viruses transmitted in spam." Their attorney is Jon Praed of the Internet Law Group, who is one of the most experienced anti-spam lawyers around, with whom I have worked in the past. more

Gary Warner: We Are Well Past Time to Declare a Spam Crisis in China

In a blog post last week, Gary Warner, director of research in computer forensics at the University of Alabama's (UAB) computer and information sciences department, wrote that it is well past time for someone to declare a "Spam Crisis in China". The warning comes along with UAB's reports that most of the spam they receive has ties to China. "It is very normal that more than one-third of the domain names we see each day in spam messages come from China," Warner wrote. "When one also considers the many '.com' and '.ru' domain names which are also hosted in China, the problem is much worse. More than half of all spam either uses domain names registered in China, is sent from computers in China, or uses computer in China to host their web pages." more

Fight Phishing With Branding

Phishing, stealing personal information by impersonating a trusted organization, is a big problem that's not going away. Most antiphishing techniques to date have attempted to recognize fake e-mail and fake web sites, but this hasn't been particularly effective. A more promising approach is to brand the real mail and real web sites. more

Cyber Security and the White House, Part 2 - Cyberwarfare

This is a follow-up to my previous post on Cybersecurity and the White House. It illustrates an actual cyberwarfare attack against Estonia in 2007 and how it can be a legitimate national security issue. Estonia is one of the most wired countries in eastern Europe. In spite of its status of being a former Soviet republic, it relies on the internet for a substantial portion of everyday life -- communications, financial transactions, news, shopping and restaurant reservations all use the Internet. Indeed, in 2000, the Estonian government declared Internet access a basic human right... more

New Research Finds Over 80% of Domain Names Used by Phishers Are Legitimate Domains

New research from the Anti-Phishing Working Group (APWG) has found that up to 81% of domain names used for phishing are legitimate domains that have been hacked. More specifically, out of the 30,454 phishing domains under observation, only 5,591 domain names (18.5%) were registered by phishers according to APWG. The remaining small percentage of the domains used in phishing belonged to subdomain resellers such as ISPs and other web-based services. more

Another Attack, Another Reason for the Urgency of DNSSEC Adoption

News broke this week about an attack in Puerto Rico that caused the local websites of Google, Microsoft, Yahoo, Coca-Cola, PayPal, Nike, Dell and Nokia to be redirected for a few hours to a phony website. The website was all black except for a taunting message from the computer hacker responsible for the attack... more

A Few Thoughts on the Future of Email Authentication

With the Online Trust Alliance Town Hall Meeting and Email Authentication Roundtable next week as well as the RSA Conference, I decided to pause and think about where we are and where we might be headed with regard to email authentication. Over the years, many of us have collectively worked to provide a framework for authenticating email... more

Domain Name Registries Must Do More to Protect Highly-Trafficked Domains

With the recent attacks against high-profile New Zealand domain names including Coca-Cola.co.nz and F-Secure.co.nz, fingers are naturally pointing to Domainz, the registrar of record for these domains, as the party responsible for this lapse in security. While domain name registrars certainly need to ensure the security and stability of their systems, domain name registries must also step up and take responsibility for mitigating risks posed by hackers... more

The Cybersecurity Act of 2009

Four senators (Rockefeller, Bayh, Nelson, and Snowe) have recently introduced S.773, the Cybersecurity Act of 2009. While there are some good parts to the bill, many of the substantive provisions are poorly thought out at best. The bill attempts to solve non-problems, and to assume that research results can be commanded into being by virtue of an act of Congress. Beyond that, there are parts of the bill whose purpose is mysterious, or whose content bears no relation to its title. more

Government Regulation of Cybersecurity: Partnership (or Power Grab) in the Making?

A cybersecurity bill introduced in the U.S. Senate on April 1st, 2009 would give the United States federal government extraordinary power over private sector Internet services, applications and software. This proposed legislation is a direct result of a review ordered by the Obama administration into government policies and processes for defending against Internet-born attack. The focus of the bill, according to a summary released by the sponsoring senators, is on establishing a new partnership between the public and private sectors in a joint effort to bolster Internet security... more

Innovation and Cybersecurity Regulation

The market has failed to secure cyberspace. A ten-year experiment in faith-based cybersecurity has proven this beyond question. The market has failed and the failure of U.S. policies to recognize this explains why we are in crisis. The former chairman of the Security and Exchange Commission, Christopher Cox, a longtime proponent of deregulation, provided a useful summary of the issue when he said, "The last six months have made it abundantly clear that voluntary regulation does not work."... more

HTTPS Web Hijacking Goes From Theory to Practice

I've been privately talking about the theoretical dangers of HTTPS hacking with the developers of a major web browser since 2006 and earlier last month, I published my warnings about HTTPS web hacking along with a proposed solution. A week later, Google partially implemented some of my recommendations in an early Alpha version of their Chrome 2.0 browser... This week at the Black Hat security conference in Washington DC, Moxie Marlinspike released a tool called SSL Strip... more

Proposed Law Seeks to Expose Internet Addressing for Child Safety

U.S. Republican politicians on Thursday introduced a bill that would require Internet service providers and network operators to track the use of and maintain records for their publicly accessible wired and wireless networks. Two bills have been introduced... Each of the bills carries the title "Internet Stopping Adults Facilitating the Exploitation of Today’s Youth Act," and is referred to as the "Internet SAFETY Act." more

Should We Make the Possession of Malware a Crime?

In the U.S., it is a federal crime to use malware to intentionally cause "damage without authorization" to a computer that is used in a manner that affects interstate or foreign commerce. Most, if not all, U.S. states outlaw the use of malware to cause damage, as do many countries. The Council of Europe's Convention on Cybercrime, which the United States ratified a few years ago, has a provision concerning the possession of malware. Article 6(1)(b) of the Convention requires parties to the treaty to criminalize the possession of malware "with intent that it be used for the purpose of committing" a crime involving damage to a computer or data... more
