ICANN’s First Official Report on Whois Data Problems

ICANN has submitted the first report of what will be a series of annual reports summarizing its "expierince" with the Whois Data problems and inaccuracies. While emphasizing that "ICANN-accredited registrars are obligated by the terms of their accreditation agreements to investigate and correct any reported inaccuracies," the report provides the following conclusions: more

More than 99% of Email is Spam?

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

MARID is Dead

As long suspected by some, the IETF is going to be closing up the Mail Transfer Agent Authentication in DNS (MARID) Working Group according to today's post by Ted Hardie, co-AD for Applications. Larry Seltzer of eWeek was right on target about this: "The rest of the SID standards process will now be a waste of time thanks to Microsoft, and the other participants will afterwards pick up the pieces and get the job done with another spec." more

There Is No “Spam Problem”

This month I thought I could feel smug, deploying Postfix, with greylisting (Postgrey), and the Spamhaus block list (SBL-XBL) has reduced the volume of unsolicited bulk commercial email one of our servers was delivering to our clients by 98.99%. Alas greylisting is a flawed remedy, it merely requires the spambots to act more like email servers and it will fail, and eventually they will... more

GDPR PII Time-Bomb? Kill it With Fire!

Hi! My name is spamfighter. I investigate spam and phish in a post-GDPR dystopia. Recently, I invented Fire, to save you millions of €uros. One day, my Boss suggested I automate some of my processes. I, for one, welcome our Robot Overlords (and a happy boss), but I can be exacting about the tools I use. Perhaps not to the degree of the infamous Van Halen 'no brown M&M's' contractual clause but I have no patience for poorly-designed software, and truly dislike typing when... more

Maybe the IETF Won’t Publish SPF and Sender-ID as Experimental RFCs After All

Yesterday, the IESG, the group that approves RFCs for publication received an appeal from Julian Mehnle to not to publish the Sender-ID spec as an experimental RFC due to technical defects. IESG members' responses were sympathetic to his concerns, so I'd say that a Sender-ID RFC has hit a roadblock. The problem is simple: Although Sender-ID defines a new record type, called SPF 2.0, it also says that in the absence of a 2.0 record, it uses the older SPF1 record. Since SPF and Sender-ID can use the same records, if you publish an SPF record, you can't tell whether people are using it for SPF or Sender-ID. Ned Freed commented... more

80% of Spam Originating from Home PCs

The majority of spam -- as much as 80 per cent of all unsolicited marketing messages sent -- now emanates from residential ISP networks and home user PCs. This is due to the proliferation of spam trojans, bits of surreptitious malware code embedded in residential subscriber PCs by worms and spyware programs. Worm attacks are growing in frequency because they provide a fast means of infecting a vast number of computers with spam trojans in a very short period of time. It's no surprise that many service providers report an upsurge in spam traffic immediately following a worm attack. more

Is Industry Underestimating the Ending Dot?

According to RFC1034, "cnn.com" and "cnn.com." should be the same domain names. However, it doesn't appear that programmers always understand that trailing dots can be added to domain names. Web servers also can't seem to agree what to do with a period at the end of a host name. IIS, thttp, and Akamai's Web server all get confused while Apache doesn't seem to care. How much other software behaves incorrectly because of a trailing period on a domain name? Can spam-filtering software be bypassed with dotted email addresses? Here is a situation when bad things can happen -- "WebShield SMTP infinite loop DoS Attack"... more

Sender-ID Back from the Dead

With the closure of IETF's MARID group a month ago, many of us have left Microsoft's Sender-ID standard for the dead. After being rejected by the Apache Foundation and the Debian Project over licensing issues, and causing the closure of MARID for some of the same issues (in addition to already long running technical ones), some thought that Microsoft may have just buried it and gone on to better things like IETF's new MAILSIG group (in formation). But just like the ghost of Hamlet's father it just refuses to die and now it looks like it is coming back to life in a new reincarnation... more

With No Privacy Standards Who Knows Who Is Abusing The Whois Database

John Banks is a loan officer in New York. John's supervisor recently warned John about the potential number of bad loans he may be carrying as part of his portfolio. To dump some of the bad loans he might be carrying, John came up with a scheme. He pointed his web browser to www.whois.org and entered terms denoting disease or poor health such as 'cancer' and 'illness'. This query on the Internet's WHOIS database reported results of names and addresses of domain name owners who had developed websites devoted to providing information on certain serious illnesses. John compared these names and addresses with those in his portfolio of loans. For the matches, he canceled the loans and required immediate payment-in-full. more

EFF on Goodmail: Further Confusing an Already Confused Issue

Cindy's piece on the EFF website seems to be a bit of a pastiche, with elements taken out of various articles (some outright wrong, some merely misinformed) that have been doing the rounds of the media for quite a while now about Goodmail. She started off comparing AOL and Goodmail with the old email hoax about congress taxing email. That same line was used in a CircleID post by Matt Blumberg, CEO & Chairman of Returnpath... Various other quotes from different places - Richard Cox from Spamhaus on CNN for example. However a lot of the quotes in those articles are being based on wrong or out of context assumptions, starting with one that goes "AOL is going to remove all its existing whitelists and force people to use Goodmail". more

ICANN Ordered by Illinois Court to Suspend Spamhaus.org

Apparently, at this stage, it is only a proposed ruling. But I am no lawyer. This story has been discussed before, when Spamhaus, which is located in the UK, was sued in the US by a spammer. They refused to come before the court as "they do no business in Illinois, and are located in the UK...After this court ruling, Spamhaus.org was under a DDoS attack, in my opinion for the purpose of preventing users from reaching the information it provided about the court ruling. This was done along-side a Joe Job, sending fake email appearing to come from Spamhaus's CEO... more

IP Addresses and Personally Identifiable Information

I don't normally cheer for Google when I don't own shares in the company, but this time I will make an exception. Alma Whitten, Software Engineer at Google, today posted to their Public Policy Blog that IP addresses shouldn't be considered Personally Identifiable Information (PII). This is not a problem in the United States but it is in the EU, and if the EU actually were to legislate this it would most definitely affect Microsoft and Google's business functionality in the EU... more

AOL Fires Across the Bow of Spam-Friendly ISPs

The North American Network Operators Group (NANOG) conference, a gathering of Internet Service Provider (ISP) engineers and vendors convenes three times a year for mostly technical conversation along with social networking. The recent NANOG conference in Reston Virginia saw some unusually direct talk about Spam and the ISPs that tolerate it from America Online's Postmaster, Charles Stiles. more

Challenges in Anti-Spam Efforts

Without commenting on the particulars as they relate to Goodmail -- especially since I am on the advisory board for Habeas, a competitor -- let me note that public discussion is largely missing the nature of the current Internet mail realities and the nature of the ways we can deal with them. There are two articles in the current issue of the Internet Protocol Journal, of which I wrote one, that provide some useful background about this reality. Simply put, Internet mail needs to sustain spontaneous communications... more
