Why I Want a .PAYPAL New gTLD

I use Paypal, and I am quite satisfied with how it helps me with my business: it is still a little hard to use, and I don't use all functions of the tool, but it is not so expensive, it is fast and efficient, and Paypal does not send so many emails. In one word, Paypal rocks... The only problem that I have with Paypal is the number of fake emails that I receive. Of course, I easily identify them as they come in and luckily, G Suite (Gmail) does an excellent job at blocking all spam and phishing. more

New Study Revealing Behind the Scenes of Phishing Attacks

The following is an overview of the recent Honeynet Project and Research Alliance study called 'Know your Enemy:Phishing' aimed at discovering practical information on the practice of phishing. This study focuses on real world incidents based on data captured and analyzed from the UK and German Honeynet Project revealing how attackers build and use their infrastructure for Phishing based attacks. "This data has helped us to understand how phishers typically behave and some of the methods they employ to lure and trick their victims. We have learned that phishing attacks can occur very rapidly, with only limited elapsed time between the initial system intrusion and a phishing web site going online..." more

Yahoo Addresses a Security Problem by Breaking Every Mailing List in the World

DMARC is what one might call an emerging e-mail security scheme. It's emerging pretty fast, since many of the largest mail systems in the world have already implemented it, including Gmail, Hotmail/MSN/Outlook, Comcast, and Yahoo. DMARC lets a domain owner make assertions about mail that has their domain in the address on the 'From:' line. It lets the owner assert that mail will have a DKIM signature with the same domain, or an envelope return (bounce) address in the same domain that will pass SPF validation. more

Spamhaus Appeal: They Win on Substance

The Seventh Circuit has issued its opinion in the continuing saga of E360 Insight vs. the Spamhaus Project. While it is not a complete victory for Spamhaus, they did about as well as anyone could have hoped for under the circumstances. E360 won on the procedural issue, while Spamhaus won on the substance. The procedural issue was whether the default judgement against Spamhaus was properly granted last September. The court session was so odd that the appeals decision quotes several pages of the transcript. more

Why Foldering Adds Very Little Security

I keep hearing stories of people using "foldering" for covert communications. Foldering is the process of composing a message for another party, but instead of sending it as an email, you leave it in the Drafts folder. The other party then logs in to the same email account and reads the message; they can then reply via the same technique. Foldering has been used for a long time, most famously by then-CIA director David Petraeus and his biographer/lover Paula Broadwell. Why is foldering used? more

How Does the Acceptance of All Domain Names in Open-Source Software Look in 2021?

A recent study carried out by Governance Primer on behalf of the Universal Acceptance Steering Group (UASG) identified trends in the acceptance of all domain names in software hosted at Github, the largest open-source repository globally. This research builds on top of previous efforts aimed at identifying the underlying issues that result in problems when different applications need to handle Internationalized Domain Names (IDNs) and new gTLDs, particularly when it comes to email addresses. more

Whither WGIG?

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

Oklahoma Spammer Fighter Loses Even Worse

Last December I wrote about Mark Mumma, who runs a small web hosting company in Oklahoma City and his battle with Omega World Travel a/k/a cruise.com. Mumma lost his CAN SPAM suit agains them in December, but Omega's countersuit for defamation went to trial last week, and I hear that the jury awarded Omega $2.5 million in damages, which Mumma is not likely to be able to pay. This may be painted in some circles as a huge defeat for anti-spam activists, but it's not... more

Universal Acceptance – Making the Internet Work for Everyone

Back in 2014, to foster innovation and to better the choice in domain names, ICANN introduced new generic top-level domains through its New gTLD Program. It was a monumental move that enabled businesses, individuals, and communities across the globe to mark their presence on the Internet. Allowing users to be present digitally in their chosen language (non-ASCII characters and scripts) gave opportunities to local businesses, civil societies, and governments to better serve their communities. more

Minding Your IP Address Reputation

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

China Hacks Google, Etc.

Many news sources are reporting on how Google and other corporations were hacked by China. The reports, depending on vendor, blame either PDF files via email as the original perpetrator, or lay most of the blame on an Internet Explorer 0day. more

Something’s Cooking at IETF with Email Authentication

A few months ago, Ted Hardie (AD of Applications for the IETF) informed the MARID WG in the closure announcement as follows: "Given the importance of the world-wide email and DNS systems, it is critical that IETF-sponsored experimental proposals likely to see broad deployment contain no mechanisms that would have deleterious effects on the overall system. The Area Directors intend, therefore, to request that the experimental proposals be reviewed by a focused technology directorate..." more

Are Portable Email Addresses Possible?

News reports say that the Israeli government is close to passing a law that requires portable e-mail addresses, similar to portable phone numbers. Number portability has been a success, making it much easier to switch from one provider to another, and address portability might ease switching among ISPs. But e-mail is not phone calls. Is it even possible? more

Rumblings for an In-Session Recommendation Engine at Email Service Providers (Part I)

Email Campaign builders (marketers) are flying blind. I know ESPs are genuinely timely about rolling out new products for their marketers, but there is a colossal gap in adopting data science and MLops into the email campaign building workflow.  Even MailChimp does not seem to have the answer just yet, and half-baked attempts over the years to optimize the subject line haven't been inspiring. more

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. more
