It shouldn't be a big surprise to hear that phishing is a big problem for banks. Criminals send email pretending to be a bank, and set up web sites that look a lot like a bank. One reason that phishing is possible is that e-mail has no built in security, so that if a mail message comes in purporting to be from, say, accounts@bankofamerica.com, there's no easy way to tell whether the message is really from bankofamerica.com, or from a crook. more»
A lot of people are fascinated by the news story that Anonymous managed to listen to a conference call between the FBI and Scotland Yard. Some of the interest is due to marvel that two such sophisticated organizations could be had, some is due to schadenfreude, and some is probably despair: if the bad guys can get at these folks, is anyone safe? more»
A consortium of companies including Google, Microsoft, Facebook and Paypal have announced that they were collaborating and coming up with a new protocol known as DMARC -- the Domain-based Message Authentication, Reporting and Conformance. What is DMARC? more»
There has been a lot of recent discussions and questions about reputation, content and delivery of email. I started to answer some of them, and then realized there weren't any basic reference documents I could refer to when explaining the interaction. So I decided to write some. This post is about IP address reputation with some background on why IPs are so important and why ISPs focus so heavily on the sending IP. more»
In a presentation EU Commissioner Viviane Reding gave a preview of the new Privacy regulation her DG is preparing. As she states, privacy rules need to be brought up to date and harmonized. With all 27 member states having the same rules and tools to enforce, a company only will deal with one privacy commissioner... So, what if we, for the sake of this blog, take this initiative towards spam and cyber crime. What would this do to spam enforcement? more»
While Canada was dragging the chain when it came to introducing anti-spam legislation, it is now making up for lost time. Ottawa's new law -- expected to be operational early this year -- has severe fines for violations and is viewed by some as too tough. Known as CASL, the new law aims to crack down on spammers and mailing list companies but in doing so, tightly regulates the way businesses can market to prospective customers via email and online. more»
For email usage, abuse reporting requires cooperation between senders and receivers. That's why RFC 5965 specified a standard format for it. However, Wikipedia lists only 18 feedback providers today. It is often said that the number of legitimate mailbox providers in the world is rather small, possibly some hundreds of thousands, but certainly more than that. more»
In my last post I blogged about greylisting, a well-known anti-spam technique for rejecting spam sent by botnets. When a mail server receives a an attempt to deliver mail from an IP address that's never sent mail before, it rejects the message with a "soft fail" error which tells the sender to try again later. Real mail senders always retry, badly written spamware often doesn't. I found that even though everyone knows about greylisting, about 2/3 of IPs don't successfully retry. more»
Greylisting is a hoary technique for rejecting spam sent by botnets and other poorly written spamware. When a mail server receives an attempt to deliver mail from a hitherto unseen sending host IP address, it rejects the message with a "soft fail" error which tells the sender to try again later. Real mail software does try again, at which point you note that the host knows how to retry and you don't greylist mail from that IP again. more»
Signing Email is now a Draft Standard! Signing email transitioned from a proposed standard to a draft standard (RFC6376 -- one of the new RFCs) over at the IETF a few days ago. The other is RFC6377. Let's go through a brief history of DKIM RFCs to refresh our memories... more»
How large is your digital footprint? If you pulled together your email account, web site, blog, social networking accounts, and every other virtual identity you have online, just how well known are you on the Internet? Have you ever stopped to consider what happens to your online identity when you die? How would your online friends know? What would happen to your accounts and your content? more»
I visited Judge Fogel's courtroom this morning to listen to the oral motions in the Holomaxx cases. This is a general impression, based on my notes. Nothing here is to be taken as direct quotes from any participant. Any errors are solely my own. With that disclaimer in mind, let's go. more»
The best part is ... this isn't one of those 'now that I've got your attention' tricks, like one of those old "free beer" posters; there really is a ton of stuff happening above the 49th parallel this summer. To begin with, as a precursor to Canada's Anti-spam Law coming into effect later this year, the Office of the Privacy Commissioner, the Canadian Radio-television Telecommunications Commission, and Industry Canada have all issued regulations, the latter two in draft form with an RFC. more»
Last week, Synacor joined other major mailbox providers by introducing a complaint feedback loop service -- powered by ReturnPath. This increases the number of public complaint feedback loops available today across the internet. more»
In our last instalments we discussed the various ways to encode non-ASCII character sets, of which UTF-8 is the winner, and some complex approaches that tried to make UTF-8 mail backward compatible with ASCII mail. After years of experiments, the perhaps surprising consensus is that if you're going to do international mail, you just do it. more»
