Once you've determined that you can trust the signer of a message, as we discussed in part 3, it's easy to extrapolate that various portions of the message are equally trustworthy. For example, when there's a valid DKIM signature, we might assume that the From: header isn't spoofed. But in reality, DKIM only tells us two basic things... more
Last year, MAAWG published a white paper titled Trust in Email Begins with Authentication [PDF], which explains that authentication (DKIM) is “[a] safe means of identifying a participant-such as an author or an operator of an email service” while reputation is a “means of assessing their trustworthiness.”

When I was employed, I ran my own mail server and my own BlackBerry Enterprise Server, and I had things tuned pretty much exactly as I wanted them. My incoming mail got some custom processing that looked the sender's address up in my address book and assigned the message a category... I was a very happy email user. Now that I'm on my own, I've decided not to run my own server and all that software, and I've switched to Gmail and the T-Mobile BlackBerry server... Surprisingly, though, I'm mostly still happy... more
While the news will not be terribly surprising to CircleID readers, Google's latest report on the status of spam and 2009 predictions posted today, might be of particular interest due to the company's shear email processing volume at 2 billion enterprise email connections per day (drawn from company owned Postini Message Security network)... more
In a 52 page security report released by Cisco, the company has confirmed what has been consistently been observed through out this year: "the Internet-based attacks are becoming increasingly sophisticated and specialized as profit-driven criminals continue to hone their approach to stealing data from businesses, employees and consumers." The 2008 edition of the report has specified the year's top security threats and offers recommendations for protecting networks against attacks that are propagating more rapidly, becoming increasingly difficult to detect, and exploiting technological and human vulnerabilities. more
The recent Facebook case has placed the spotlight on Canada's ongoing failure to address its spam problem by introducing long overdue anti-spam legislation. The fact that organizations are forced to use U.S. courts and laws to deal with Canadian spammers points to an inconvenient truth – Canadian anti-spam laws are woefully inadequate and we are rapidly emerging as a haven for spammers eager exploit the weak legal framework. more
Working in the anti-spam and online malware fight can be depressing or at best invoke multiple personality disorder. We all know things are bad on the net, but if you want a dose of stark reality, check out Brian Kreb's fantastic 'Security Fix' blog on the Washington Post site... Speaking to an old friend who asked me what I was doing these days, I recently likened the fight against this relentless onslaught to having one's pinky in a dyke, and there are days when I don't even think we have a dyke! more
Hoang v. Reunion.com sidesteps an eagerly anticipated legal dispute over the legality of commercial address book scraping and 'send-to-a-friend' emails, and also highlights the damage that can cascade when a federal Circuit Court woefully misreads a statute. more
ICANN introduced a requirement for domain name registrars to send out annual notices to all their customers (registrants) to check the Whois on their domain names to ensure the information is correct. While this seemed fairly reasonable (if cumbersome), the fact is it confuses the heck out of people -- and creates a whole lot of confusion for registrants. But that was a problem we could deal with. Fast-forward to October, 2008... more
U.S. authorities announced today that they have shut down one of the largest spam operations in the world, an extensive network with ties to Australia, New Zealand, India, China and the United States. The group, dubbed 'HerbalKing' by spam fighting organizations, had been active as far back as 2005 and became notorious as the number one worst spam gang on the Internet for much of 2007 and 2008 according to Spamhaus, a non-profit anti-spam research group. more
If the headlines are to be believed, spam is now entirely legal in Virginia and anyone can send whatever they want without any fear of reprisal, ever. Looking beyond the headlines, it appears that the Virginia Supreme Court's ruling in AOL's case against formerly convicted spammer Jeremy Jaynes declares that the Virginia anti-spam law violates the Constitutional protection of anonymous speech, and thus is null and void. more
We are at an inflection point in our lifetimes. The Internet is broken, seriously broken... Almost all of the systems currently in use on the Internet are based on implicit trust. This has to change. The problem is that these systems are so embedded in our everyday lives that it would be, sort of like, changing gravity, very difficult. more
As if conversations between technologists and marketers weren't already difficult enough, it appears that the Direct Marketing Association's (DMA) Email Experience Council wants to redefine long-standardized terms such as "header" and "message." more
Way back in 1995, Wired reporter Simson Garfinkel gave Jeff Slaton the name "Spam King." Less than a year later, Sanford Wallace earned the title -- and soon had to share it (and his upstream provider) with Walt Rines. Others have come and gone; Sanford and Walt reappear every few years, together or separately, only to be sued away again... it seems as if any spammer noticed by law enforcement is immediately crowned "the Spam King," even when there are multiple such crownings happening at the same time. more
They say (whoever "they" are) that good things come in threes, and that certainly seems true for law enforcement against spammers this week. In New York, Adam Vitale was sentenced to 30 months in prison and ordered to pay $183,000 in restitution for a week of spamming AOL back in 2005... In Illinois, an FTC settlement requires Spear Systems and company executives Bruce Parker and Lisa Kimsey to give up $29,000, stop making "false or unsubstantiated claims about health benefits" of their products, and bars them from violating CAN-SPAM ever again... And finally, in Seattle, the Robert Soloway case continues... more
