Will Splogs Kill .INFO Domains?

An article in the September issue of Wired explores search spam and the role of .info domain names. The article, titled "Spam + Blogs = Trouble" is a good overview of the problems of search spam, blog spam, and other various forms of web activity designed to take advantage of search engines. (The article will be online September 5, but you can read it on page 104 of the print edition that is available to subscribers now). For those not versed in search spam, it's basically creating multiple websites, typically auto-generated by computers, to get good search rankings and then monetize the resulting search traffic through AdSense or affiliate programs. The article focuses much of its attention to splogs, or auto-generated blogs...

Making DKIM More Useful with Domain Assurance Email

The IETF DKIM working group has been making considerable progress, and now has a close-to-final draft. DKIM will let domains sign their mail so if you get a message from [email protected], the furble.net mail system can sign it so you can be sure it really truly is from furble.net. But unless you already happen to be familiar with furble.net, this doesn't give you any help deciding whether you want the message. This is where the new Domain Assurance Council (DAC) comes in...

A Fundamental Look at DNSSEC, Deployment, and DNS Security Extensions

In looking at the general topic of trust and the Internet, one of the more critical parts of the Internet's infrastructure that appears to be a central anchor point of trust is that of the Domain Name Service, or DNS. The mapping of "named" service points to the protocol-level address is a function that every Internet user relies upon, one way or another. The ability to corrupt the operation of the DNS is one of the more effective ways of corrupting the integrity of Internet-based applications and services. If an attacker can in some fashion alter the DNS response then a large set of attack vectors are exposed. ...The more useful question is whether it is possible to strengthen the DNS. The DNS is a query -- response application, and the critical question in terms of strengthening its function is whether it is possible to authenticate the answers provided by the DNS. DNSSEC provides an answer to this question.

Another Try at Proof-of-Work e-Postage Email

Another paper from the Fifth Workshop on the Economics of Information Security, (WEIS 2006) is Proof of Work can Work by Debin Liu and L, Jean Camp of Indiana University. Proof of work (p-o-w) systems are a variation on e-postage that uses computation rather than money. A mail sender solves a lengthy computational problem and presents the result with the message. The problem takes long enough that the sender can only do a modest number per time period, and so cannot send a lot of messages, thereby preventing spamming. But on a net full of zombies, proof of work doesn't work.

Net Neutrality Is As Silly As So-Called Internet Governance

From the perspective of Internet security operations, here is what Net Neutrality means to me. I am not saying these issues aren't important, I am saying they are basically arguing over the colour of bits and self-marginalizing themselves. For a while now I tried not to comment on the Net Neutrality non-issue, much like I didn't comment much on the whole "owning the Internet by owning the Domain Name System" thingie. Here it goes anyway. Two years ago I strongly advocated that consumer ISP's should block some ports, either as incident response measures or as permanent security measures...

FTC Issues Statement on Whois Databases

A recent statement released by the U.S. Federal Trade Commission emphasized that the Whois databases should be kept "open, transparent, and accessible," allowing agencies like the FTC to protect consumers and consumers to protect themselves: "In short, if ICANN restricts the use of Whois data to technical purposes only, it will greatly impair the FTC's ability to identify Internet malefactors quickly -- and ultimately stop perpetrators of fraud, spam, and spyware from infecting consumers' computers," the statement states."

Phishing Moving to the Web Channel

Today we received one of the first phish attempts to be made as a web spam (comment spam/blog spam) attempt. I wasn't convinced, and thought that perhaps it was a way to gather and verify RELEVANT online identities. Someone put me straight. It's phishing. I've often in the past had run-ins with the good folks in the anti virus realm back between 1996 and 2005 who thought Trojan horses and then spyware were not part of their business. Years later the AV business people ruled it is part of their business and ran to catch up. Same with botnets.

How Much Money Do Spammers Make?

News reports say that high profile Ryan Pitylak was fined $10 million by the Texas Attorney General. A few days ago, he paid a $1M settlement to Microsoft. Since it had been widely reported that he'd made between $3M and $4M during his spamming career, that seemed like a pretty good deal for him. As I commented to the San Antonio Express, this new fine is more in line with what he did, and at least relieves him of all his ill-gotten gains...

Black Frog: Next Generation Botnet, No Generation Spam Fighting

Black Frog -- a new effort to continue the SO-CALLED Blue Security fight against spammers. A botnet, a crime, a stupid idea that I wish would have worked -- News items on Black Frog. Blue Frog by Blue Security was a good effort. Why? Because they wanted to "get spammers back". They withstood tremendous DDoS attacks and abuse reports, getting kicked from ISP after ISP. ...The road to hell is filled with good intentions. Theirs was golden, but they got to hell, quite literally, non-the-less. ...When Blue Security went down, some of us made a bet as to when two bored guys sitting and planning their millions in some café would show up, with Blue Security's business plan minus the DDoS factor. Well -- they just did.

Questioning Parked Domains and Google AdNonSense

Is contextual advertising helping or hurting the web? It basically started with Google Adsense even though the concept wasn't new. It had never been done on the scale that Google did it. Now we have Yahoo Publisher. MSN is building their version. We have Konterra and a whole lot of other companies scrambling to cash in on the contextual ad craze. Initially contextual advertising seems like a good idea. Ads based on the content of your website that might benefit your readers or visitors. Ads that are related to the content you produce that will also help you make a little money for your efforts. However greed ruins all good things. Now there are probably millions of webpages online that are built for the sole purpose of cashing in on contextual advertising. ...To make money with contextual advertising you want your content to be bad. Yes, you want it to be bad.
