Child Porn Accusation As Online Extortion Tactic

Glenn writes "There's a story on silicon.com about a new twist in the tactics used by online extortionists trying to blackmail ecommerce sites with denial of service attacks. Yesterday one blackmailer threatened to send out child pornography emails in UK gambling site Blue Square's name if it didn't pay up 7000 Euros." This sounds even worse than simple DoS threats.

If your ISP doesn't support SPF, point them to this and suggest they adopt it. If you don't publish SPF records, set some up.

      There's nothing wrong with SMTP... The problem lies with the lack of consensus on authentication, authorization and reputation systems for electronic mail.

      For example, using a combination of SPF and SMTP/AUTH you can easily prevent anyone who uses SPF from accepting invalid mail "from" your domain(s) while continuing to use the world's most pervasive mail transfer protocol.

      Problem is that people aren't willing to apply the time and effort required to do this globally.

      The next step is reputation, and as soon as you can be sure that the person claiming to be joe@example.com is in fact from example.com, you can begin assigning example.com a reputation. You'll see dozens of distributed reputation databases, just like IP-based blacklists, overnight.

      Want to move the process along? Add an SPF record for your domain and add an SPF milter (or equivalent for your MTA technology) to your mail server. The sooner forgeries stop, the sooner we can start building reputation and end this.

      SenderID isn't an acceptable solution. It relies on DNS, which is a fundamentally broken authentication mechanism. Remember a few years ago when all the rage was to require reverse DNS to be reasonable for SMTP requests? Remember why people stopped doing that? It wasn't because it didn't work. It was because:

      1. Lots of sites never got their RDNS entries right.
      2. DNS is unreliable.
      3. DNS resolution is usually not parallelizable.
      The result is that the spam we have now could be a denial of service attack in two ways:

      1. By overloading DNS servers of small companies.
      2. By using bogus domain names that cause 30 second stalls in your inbound traffic.
      It also fails to solve the phishing problem by providing no real, legitimate means to track the email back to an actual person, as it is trivial to register a domain like ebay-secure.com....

      To make a long story short, mechanisms like Sender-ID are impractical and aren't even a stop-gap solution because they don't solve the -real- problem, which is determining the source of a message. Instead, they solve an irrelevant side problem, that of being able to send a message with a faked source domain. That would have solved the spam problem five years ago (when this was the usual means for sending this stuff). Now, it's too little, too late.

      We need a mechanism based on verifiable key signing with the public keys transferred as an attachment to the message itself. With such a mechanism, you'd be able to track your way back through a chain of a handful of certifying keys until you get back to the certifying agency key. At that point, you have a verifiable audit trail for determining who sent the email message, and spammers will be effectively shut out unless they're willing to send messages that can be traced back to their home postal address, real email address, and real telephone number.

      Further, with a key-based mechanism, a list of legitimate IP numbers for the domain could also be sent along with the message, signed with the private key. This would give the (modest) added benefit of Sender-ID without the (potentially devastating) use of DNS to do it.
