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.

    Using SMTP as our default e-mail system has got to go...

    SMTP is wide open to the kind of attack that is being discussed here. Since there's no authentication of the sender, anybody can send out messages with the "From:" address of the desigated victim, and can smear their reputation into being anything from a spammer to a pornographer.

    The only surprise to me is that it took the bad guys this long to make the connection into this being something to make extortion threats over. It's not like this was a well-hidden problem with SMTP, sender spoofing has been done by spammers and phishers for years.

    We need to retire this standard and find a better way to move e-mail with the ability to authenticate that the claimed sender is the real sender. It'd solve this problem and a whole bunch of other ones at the same time.

      Actually, this could be done with the world's postal systems as well... Although it would cost more. The problem is not with SMTP itself, but people reliance on it for authentication, which it was never designed for. What needs to happen is the widespread adoption and use of technology like SMIME. A technology that was designed to be used for authentication.

      But we have technology that works almost perfectly with existing SMTP servers that combats this very threat. SPF, Sender ID et al are designed to confirm that the sender or sending domain is reflected accurately.

      Why should we change every MUA & MTA, almost certainly handing control of email to big business in the process, when we hold a solution in our hands. 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. If you get a virus warning from another company where your email address was forged, email them and suggest they start SPF checking. There are alwyas going to be threats to internet protocols - this threat is one we can already deal with.

      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.

      Just my $0.03 (price adjusted due to inflation).

When it comes to child pornography, people tend to get very irrational and seldom check for any form of proof or second opinion. It's kind of like being accused of being a child molester IRL. Even once you prove your innocence, no one will quite look at you the same again and some people will never truly believe your innocence.
