An acquaintance wondered why the people who run the systems that receive mail get to make all the rules about what gets delivered. After all, he noted: "The sender pays for bandwidth and agrees to abide by the bandwidth provider's rules." It is useful to think of the Internet as a collection of tubes, all leading from the periphery to the middle, where the middle is approximately "the peering point." The sender has paid for the tubes leading from himself to the middle... 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
I'd like to continue on in my review of the book Spam Kings (read part 1) and make some more comments, particularly regarding the antispammers. One thing that I really liked about the book is learning the history of some of the spam tools. I was never a participant on NANAE (news.admin.net-abuse.email; a USENET newsgroup which discusses e-mail spamming), that was before my antispam time. But I was intrigued by its history. People would gather together and discuss spammers and tools for stopping them, and sometimes spammers would stop by and the flame wars would ensue. more
The recent launch of Google Wave generated a lot of attention, and for good reason. It's recently crossed my path in a few different settings, and while the news is still fresh, there is a lot here for service providers to be thinking about. At a high level, Wave is Google's entry into the real time collaboration space, and being Web-based, is poised to disrupt the status quo, not just for vendors, but service providers as well. 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
In a tweet, EU commissioner for the Information Society Neelie Kroes congratulates OPTA on the spam fine for the golf ball printing company Backsound. Since 2004 the Dutch OPTA is the number one spam and malware fighter of the EU with a total of €1.9 million in fines. It made me ask two question to myself: How come that we seldom hear of other spam fines in the EU? And can the EU change this in any way? more
This article is the first in an occasional series on DKIM/ADSP edge cases that may not be generally recognized or understood. Many people advocate DKIM/ADSP adoption without fully recognizing potential implementation and operational issues. The fact is that the email messaging environment is fraught with opportunities for poor outcomes because of common practices that need to be considered or poorly understood implementations that are not considered... more
I am proud (or disappointed) to announce the 8th annual MIT Spam Conference, March 25th and 26th at MIT in Cambridge, Massachusetts. A regular research competition that brings out the best minds in the fight against unsolicited email. At this point it would be helpful to provide a little background on the conference and remind everyone that the Call For Papers is still open. more
The latest discovery came while researchers at a security firm found a young Russian hacker bragging in an online forum that he had collected and was ready to give away a far larger number of stolen credentials that ended up totalling 1.17 billion records, Reuters reports. more
The Coalition Against Unsolicited Commercial Email (CAUCE) has announced that Dave Piscitello, formerly VP of Security at the Internet Corporation for Assigned Names and Numbers (ICANN) has joined the CAUCE Board of Directors. more
Stepping back from the DMARC arguments, it occurs to me that there is a predictable cycle with every new e-mail security technology... Someone invents a new way to make e-mail more secure, call it SPF or DKIM or DMARC or (this month's mini-fiasco) PGP in DANE. Each scheme has a model of the way that mail works. For some subset of e-mail, the model works great, for other mail it works less great. more
Mike Hammer's thoughtful article, A Few Thoughts on the Future of Email Authentication, should trigger thoughtfulness in the rest of us. Email abuse has been around a long time. Anti-abuse efforts have too. Yet global abuse traffic has grown into the 90+% range, with no hint of trending downward. The best we hear about current effectiveness is for last-hop filtering, if you have the money, staff and skills to apply to the problem... 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
For an organization where people argue for hours over arcane minutiae, it's remarkable that virtually everyone agrees that ICANN should serve the "global public interest" and build "consumer trust" in the Internet. Although it's only three pages long, ICANN's Affirmation of Commitments (AoC) cites "public interest" five times and "consumer trust" eight times. So at the ICANN meeting today in Cartagena, Colombia, a group of participants explored ways to "institutionalize" these concepts within the organization. more
In part 1, we explained that the DKIM "d=" value identifies the domain name which signed the message, which may be a different domain name from the author of the message. Tying the signing and author domains together will require an additional standard: Author Domain Signing Practices (ADSP). In IETF parlance, the "author domain" is the domain name in the From: header, so ADSP is a way for the author domain to publish a statement specifying whether any other domain name should ever sign a message purporting to be From: that author domain... more
