In June 2004, Yahoo! and a number of other companies got together to announce the Anti-Spam Technical Alliance or ASTA. While it appears to have been largely silent since then, ASTA did at least publish an initial set of best practices the widespread adoption of which could possibly have had some impact on spam... The majority of these are clearly aimed at ISPs and end users, but some are either generally or specifically relevant to email providers such as Yahoo!, Google or Microsoft... The problem: Since February this year, we have been receiving a significant quantity of spam emails from Yahoo!'s servers. In addition to their transport via the Yahoo! network, all originate from email addresses in yahoo.com, yahoo.co.uk and one or two other Yahoo! domains. Every such message bears a Yahoo! DomainKeys signature... more
You all remember cybersquatting, a popular sport in the late 90s, right? McDonalds.com, JenniferLopez.com, Hertz.com and Avon.com thankfully all point to the right web sites today, but thaiairline.com, mcdonald.com, luftansa.com, gugle.com, barnesandnobles.com and other misspellings are fake web sites intended to trap the casual surfer with a hand that's a bit too much quicker than the eye... If you want to go to the McDonalds web site, you don't even spend the 10 seconds to look it up -- you will type McDonalds.com and expect to see the latest dollar meal menu. But the same is true for the other popular form of communication -- email... more
One of my pet peeves is the headline "n %" of email is spam, it is inherently misleading, and conveys no useful data. I guess it makes for great newspaper headlines then! On our servers looking at one email address for 4 hours, we saw 208 attempted connections for SMTP traffic referring to this email address. ...One can't measure spam in relation to the amount of genuine email, because the amount of genuine email is not connected to the amount of spam... more
Last week the DMA announced with considerable fanfare that their members should all use e-mail authentication. DMA members send a lot of bulk e-mail, but not much that would be considered spam by any normal metric. (Altria's Gevalia Kaffee is one of the few exceptions.) Their main problem is their legitimate bulk mail, sent in large quantities from fixed sources, getting caught by ISPs spam filters. That happens to be one problem for which path authentication schemes like SPF and Sender ID are useful, since they make it easier to add known fixed source mailers to a recipient ISP's whitelist, and that's just what AOL and probably other big ISPs use it for. While the DMA may be implying that this is a virtuous move, in reality it's something that their members are doing anyway for straightforward business purposes. more
Now, I don't like the word "whither" any more than you do. But this Reuters article was circulating yesterday and it seemed to call for a "whither." It's a short story, so let's do a close reading. "A U.N.-sponsored panel aims to settle a long-running tug of war for control of the Internet by July and propose solutions to problems such as cyber crime and email spam, panel leaders said on Monday." We're going to decide what "internet governance" is by July? more
In my spare time when I'm not dealing with the world of e-mail, I'm a politician so now and then I put on my cynical political hat. At the FTC Authentication Summit one of the more striking disagreements was about the merits and flaws of SPF and Microsoft's Sender-ID. Some people thought they are wonderful and the sooner we all use them the better. Others thought they are deeply flawed and pose a serious risk of long-term damage to the reliability of e-mail. Why this disagreement over what one might naively think would be a technical question? more
CircleID recently interviewed Meng Weng Wong, the lead developer of Sender Policy Framework (SPF) and founder of Pobox.com. As one of the leading anti spam authentication schemes, SPF is used by companies such as AOL, Earthlink, SAP and supported by anti spam companies such as Sophos, Symantec, Brightmail, IronPort, Ciphertrust, MailArmory, MailFrontier, Roaring Penguin Software, and Communigate Pro. Last month, Microsoft announced its agreement to merge Caller ID, its own proposed anti spam authentication scheme, with SPF -- the joint standard is called 'Sender ID'. In this two-part interview, Meng Wong explains how SPF got started, where it is today and what could be expected in the future of email. more
In my roles as postmaster at CAUCE (the Coalition Against Unsolicited Commercial E-mail) and abuse.net, I get a lot of baffled and outraged mail from people who have discovered that someone is sending out spam, often pornographic spam, with their return address on the From: line. "How can they do that? How do I make them stop?'' The short answers are "easily'' and "it's nearly impossible.'' more
While people may debate the death of email, there is no question that many email servers are already overloaded with spam. Current spam solutions are beginning to address the problem, but so far they all suffer from the arms race issue - as fast as we come up with new ways to fight spam, spammers are finding new ways to deliver it to us. While the functionality of email will certainly continue, the current system must change. When the change comes, it will deliver the future of email to Microsoft. more
Network operators rely on guidance from IP address experts because not all IP addresses used on the Internet are the same. The "reputation" of email senders is especially important because some are malicious users of the system. But identifying "senders" based on their email addresses or the individual IP address of a user presents issues that are unnecessarily complex. more
As the third quarter of 2020 winds down, the domain industry continues to show development and progression amid uncertain global economic conditions. From improvements in products and additional TLD launches to growth in .brand email usage and upcoming virtual meetings, the Q3 2020: New gTLD Quarterly Report from our MarkMonitor team has a little something for everyone. more
Business email compromised (BEC) attacks targeting American companies are exploding, with an increase of over 476% in incidents between Q4 2017 and Q4 2018. Up as well is email fraud with companies experiencing an increase of over 226%. These highly targeted attacks use social engineering to identify specific company employees, usually in the finance department and then convince these employees to wire large sums of money to third-party banking accounts owned by the attackers. more
Millions of email warnings were sent out by Marriot on Friday to warn customers about the massive data breach which has affected close to half a billion guest data. more
What happens when you open an email and allow it to display embedded images and pixels? You may expect the sender to learn that you've read the email, and which device you used to read it. But in a new paper we find that privacy risks of email tracking extend far beyond senders knowing when emails are viewed. Opening an email can trigger requests to tens of third parties, and many of these requests contain your email address. more
Unsubscribing from mailing lists is hard. How many times have you seen a message "please remove me from this list," followed by two or three more pointing out that the instructions are in the footer of every message, followed by three or four more asking people to not send their replies to the whole list (all sent to the whole list, of course,) perhaps with a final message by the list manager saying she's dealt with it? more
