Searching for Truth in DKIM: Part 1 of 5

DomainKeys Identified Mail (DKIM) is the leading email authentication technology, supported by major ISPs including Google, AOL, and Yahoo! (who invented its predecessor), popular mail server software like Sendmail, and many of the best minds in email technology. But if you peruse the archives of the IETF DKIM mailing list, or start up a conversation at MAAWG, it might appear that there's still a lot of disagreement about what a DKIM signature actually means. more

Memo to John Markoff: There are No “Do Overs” in History

Think for a moment of the enduring legacy of African slavery in America. Think of the way it tainted this country's culture and politics; think of the bloody Civil War, the ghettos... What if we could roll back the clock and ensure that our society was "designed" so that slavery was never permitted and never happened? ... But what if I told you that my computer science lab was working on a "new Internet" that would solve all the terrible security and privacy problems of the existing one? Would you find this claim more credible than a proposed retroactive solution to the problem of slavery? 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

Fixing the Internet Might Break It Worse Than It’s Broken Now

Willis Alan Ramsey, who wrote "Muskrat Love," recorded one and only one studio album. The cognoscenti of country think it's a gem, an all time top ten. There's an apocryphal story that when Ramsey was pushed to make another record he allegedly retorted, "What's wrong with the first one?" We who use the Internet every day risk losing sight of what a miracle it is, and the openness that keeps it so miraculous... We also lose sight of the fact that even as the Internet's miracles occur, it's almost always broken or malfunctioning or threatening or worse in many places along the line. 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

First gTLD Signed: Dot Gov

Today is a historic day as the first generic Top-Level Domain (gTLD) has been signed. Only a few other top level domains, all of which are country code Top-Level Domains (ccTLDs), have been signed to date. This step is part of the first phase of adoption. Authoritative DNS servers need to sign and publish their zones. The second part is for the resolvers on the Internet to validate the keys. Both systems working together will provide security in the DNS. more

Yellow Parking Violation Fliers on Windshields Get Drivers to Visit Malicious Website

Security expert and malware analyst, Lenny Zeltser has examined a creative malware distribution method in the real world where fliers placed on windshield of cars scare drivers into visiting a malicious website. Zeltser writes: "Several days ago, yellow fliers were placed on the cards in Grand Forks, ND. They stated: 'PARKING VIOLATION This vehicle is in violation of standard parking regulations. To view pictures with information about your parking preferences, go to website-redacted' ... If you went to the website, you'd see several photos of cars on parking lots in that specific town..." more

A Noteworthy Report on Fast Flux Hosting

This very interesting document was released by ICANN's Generic Names Supporting Organization (GNSO) for public comment yesterday. And it asks some fundamental questions while at the same time pointing to sources such as the Honeynet Alliance's reports on fast flux. more

Monster.com Response to Security Breach Unacceptable

As some of us are continuing to learn this week the Monster.com service has again been successfully hacked. According to a security bulletin posted on Monster.com on January 23rd, 2009, the intruder gained access to the user database, while no resumes were apparently compromised... As a user of Monster.com what I find incredibly upsetting about this situation is that I had to find out about this through a security blog. more

If WHOIS Privacy is a Good Idea, Why is it Going Nowhere?

ICANN has been wrangling about WHOIS privacy for years. Last week, yet another WHOIS working group ended without making any progress. What's the problem? Actually, there are two: one is that WHOIS privacy is not necessarily all it's cracked up to be, and the other is that so far, nothing in the debate has given any of the parties any incentive to come to agreement. The current ICANN rules for WHOIS say, approximately, that each time you register a domain in a gTLD (the domains that ICANN manages), you are supposed to provide contact information... WHOIS data is public, and despite unenforceable rules to the contrary, it is routinely scraped... more

The Perpetual Peril of Open Platforms

Over at Techdirt, Mike Masnick did a great post a few weeks back on a theme I've written about before: peoples' tendency to underestimate the robustness of open platforms. "Once people have a taste for what that openness allows, stuffing it back into a box is very difficult. Yes, it's important to remain vigilant, and yes, people will always attempt to shut off that openness, citing all sorts of "dangers" and "bad things" that the openness allows..." more

Spam Fighting: Lessons from Jack Bauer?

As I blogged about several months ago, as did numerous other anti-spam bloggers, David Ritz was sued by Jeffrey Reynolds and a judge in North Dakota agreed with Reynolds. At the heart of the case was that Ritz engaged in anti-spam activities using techniques known only to a small subset of advanced computer users, and used these techniques maliciously against Reynolds... Back in the olden days of spam fighting, some anti-spammers used to use malicious techniques against spammers in order to shut them down... more

PIR’s Anti-Abuse Policy for .ORG Offers No Due Process for Innocent Domain Registrants

PIR, the registry operator for .org, has sent notices to registrars that it is implementing an anti-abuse policy that offers no due process for innocent domain registrants... While it's good intentioned, there is great potential for innocent domain registrants to suffer harm, given the lack of appropriate safeguards, the lack of precision and open-ended definition of "abuse", the sole discretion of the registry operator to delete domains, and the general lack of due process. more

An Early Look at the State of Spam in 2009, Social Networking Spam on the Rise

As recently reported, spam volumes indicate spam has nearly jumped back up to its pre-McColo shutdown levels. However, Symantec's The State of Spam report has also observed that in recent days spammers are increasingly piggybacking on legitimate newsletters and using the reputation of major social networking sites to try and deliver spam messages into recipients' inboxes... In its special URL investigation the report also indicates that on average approximately 90 percent of all spam messages today contain some kind of a URL. Additionally, analysis of data from past recent days, according to Symantec, have shown that 68% of all URLs in spam messages had a '.com' Top-Level Domain (TLD), 18% had a China's '.cn' ccTLD and 5% had a '.net'. more

Gaza Conflict Spilling Over Into the Internet, Cyberwar Underway

Whatever your personal perspective of the rights and wrongs of the current Arab-Israeli war in Gaza, there is a second front being fought on the Internet, says Jart Armin of HostExploit.com in a blog post today. "This form of warfare is a battle of words and often vivid imagery engaged by hackers from either side of the divide." more
