Spammers Stoop To New Low

mathowie writes "I received an unsolicited spam this week from MonsterHut, extolling the virtues of their "products" which are "email marketing" (they're a spam cannon). After reporting it at Spamcop, I received an interesting email from their bandwidth host. It seems that before they could cancel MonsterHut's account for violating their terms of service, MonsterHut began suing them. The worst part? A judge granted MonsterHut a temporary restraining order, forcing Paetec to keep their site online while they continue spamming, before Paetec even knew about the suit. Paetec is collecting affadavits from people that received the spam, so if you did, fill one out. It may be their only chance against the court. How far will spammers go to get their word out? When's it going to stop?"

      I would also agree with this point. If you opt-in - even if you don't realize it - it's not spam. I don't like it that way but if they put up say, a check box like the one below this message when I typed it in that says "Post Anonymously" I should not be able to complain when it shows my e-mail address.
      While I think most spammers deserve at least Summary Execution or even more severe punishment (as soon as I figure out what kind of punishment would be more severe) what it sounds like, is that this company was buying addresses from others where people probably opted in and didn't realize it, then some complained when they got mails and didn't realize they had inadvertantly opted in to something.
      It might also include some where the party they bought the E-mail addresses from were in fact spamming and Monster Hut was unaware of it (or claims that they were unaware). But what seems odd to me is that this company apparently was - if the claims are true - using valid return addresses and was clearly identifying whom they were. Two practices that real spammers never do.

      I agree as well. It seems like the ISP was going to institute a "shut them down first and ask questions later" scenario. That is probably quite valid if someone really is spamming. However the contract they signed - if the trial documents are correct - indicates they knew the company was in the business of sending commercial e-mail where the person agreed to get it. If true, then, it would imply a little more investigation would be needed because there are going to be people who forgot that they joined some of these e-mail opt-in things and then complain about it.
      I'm not trying to defend Monster Hut as they could very well be guilty. I just think that we should be pleased with the Judge's injunction until this gets litigated.
      I agree as well. In this case, the injunction preserves the status quo, since the court could if it's shown that Monster Hut really was spamming, rule in favor of the ISP. Also, if their customer is really spamming the injunction protects the ISP against retaliation because their upstream providers can't cut their feed due to the practices of the customer because the ISP can say it has no choice because it's under a court order (and if the supplier does something to interfere with that then they can get an order as well or the other provider might conceivably be in contempt of court), and if Monster Hut really was spamming, it's certainly not going to do so now, and if it did, it would be easy enough to check. Also, a trial would certainly provide considerable evidence if they were up to something unsavory.

      Reading the court transcript tells me two things that were lacking in this case: make sure you write your contracts carefully and if you have to enforce the contract, get lawyers who know something about how people send messages through the Internet; it looks like the lawyers - on both sides - were about as clueless as a 15-year-old Script Kiddie.

    Some interesting points so far...


    The biggest part of the case is whether this was actually a case of unsolicited email or not. The Defendant has stated that they believed Monsterhut was an opt-in advertising service when, in fact, they buy their lists externally with the apparent assumption that these are genuine opt-in customers.


    The Plaintiff has pointed to a provision in the contract that allows for a 2% complaint rate to avoid immediate termination of their contract. First, whoever agreed to this for the ISP should be shot considering the sheer amount of traffic Monsterhut can throw out and the number of spam messages that 2% allows for (the Plaintiff even mentions a number over 6 million outgoing messages to date, if I remember right). Apparently, this provision exists to protect Monsterhut from users who opt-in but later forget (or change their minds). When the ISP receives complaints, they are to forward them to Monsterhut who will verify the address, validity of the complaint, and apparently make the appropriate changes to their database. Makes you warm and fuzzy to know your complaints are, in fact, going directly to the spammer.


    An interesting side effect to all this is the ability to verify individuals. Quite a lot of attention is paid to whether the individuals could be identified according to their email addresses and the fact that SpamCop removes this information. It seems this comes in to play during the complaint / remediation process. But it is even more important when dealing with the court. The Defense pointed out that the Plaintiff had ample opportunity to subpoena SpamCop for identifying information, but failed to do so.


    One final interesting tidbit... the Judge wanted to define the difference the Defense saw between a case of one of the 2% mistaken users and a "true spam" case. The Defense began to talk about harvested email accounts that are not user email accounts, such as those used for contacts in Network Solution's whois database. The Plaintiff apparently perks up on this, grabs the ball, and attempts to run. It appears that Monsterhut does "use Network Solutions" to identify businesses offering services that could be marketed by Monsterhut. Since they only send mail out to, say, 5 "targeted" customers... why... this isn't the kind of mass emailings that we're all talking about. Not spam at all. Nosir.

    2. Any spam received should immediately be reported (forwardedto ). A 'legal actions may follow' reply describing our spam policy is sent to the spammer, his/her boss and the webmaster/sysadmin of the spam-sending company. In a few days, the spammer is added to a corporate blacklist for some period of time (something like 3 months). The spam-sending company is also informed on our policy. Anyone on the blacklist will have the following treatment: Any mail sent to our employees from their addresses is dumped automatically. No business will be made with anyone on the blacklist. Repeated spamming results in that we contact the ISP and CEO of the company sending spam, and ask them to stop the harassment.

    What if hitting 'S' (or pressing the hypothetical "Spam" icon in the Outlook toolbar) went so far as to make a MD5 checksum of the alleged spam and send a packet with that checksum off to a centralized server. The server then keeps a database of each checksum and increments a counter associated with that piece of alleged spam.

    Now, when the procmail scripts see incoming mail they can request the value for that checksum from the server. Depending on user configuration, a certain threshold (100, 1000, 10000?) must be reached before agreeing that it spam and proactively moving it.

    Upsides to this system: if widely used as directed it would be extremely effective at blocking spam. Relatively private (because you are sending checksums not the actual mail).

    Downsides to this system: Someone could vote multiple times to make an email appear to be spam (you could have a second packet that decrements the counter as well that people could use on their "spam" folder, or less effectively, you could restrict it to one vote per IP). There is a central server (you could mitigate this by having hierarchical servers that communicate and synchronize with their parent and children in batches). Plus the first 'n' people still have to see the spam.

  24. How I blocked 90% of my spam using qmail by embo · · Score: 2, Interesting

    Disclaimer: I admin a qmail box, so unless you have qmail as your mail server, this probably won't work. (But you really should get it, because it rocks big time, even if you can't stand DJB)

    You will need to have DJB's mess822 package installed as well. That said, I put these lines in my .qmail file (which directs how mail is delivered):

    |condredirect username-safe@mydomain.com /usr/local/bin/iftocc
    |condredirect username-safe@mydomain.net sh -c 'echo $SENDER | grep -f bccexempt > /dev/null'
    |/var/qmail/bin/preline -df /bin/sed "s/^S[Uu][Bb][Jj][Ee][Cc][Tt]:/Subject: THISISSPAM ($SENDER) /" | qmail-inject -a username-safe@mydomain.com


    Line 1: Delivers any email where my address is in the To: or Cc: lines, and exits. Otherwise, it falls through to...
    Line 2: Delivers any email where my address is in the Bcc: line, PROVIDED that the FROM address is listed in a special file in my home directory, called bccexempt. This way, it denies ANY bcc delivery to my address, unless I explicitly list the from address in my bccexempt file. It will then exit if it passes this test. Otherwise, it falls through to...
    Line 3: Injects the phrase "THISISSPAM" into the subject line. This way, I can filter on the subject line in virtually ANY email reader on the planet. Another option would be to simply throw it into /dev/null, but this way I can adjust my bccexempt filter if I need to, because it also lists the FROM address in the subject if it's marked as spam. I just have my email reader filter for THISISSPAM in the subject line, and if it finds it, it marks it as read and dumps it into a separate folder away from my Inbox where I don't have to look at it, or even know it's there. Once every 2 or 3 weeks, I quickly browse through the list of spam addresses, and if I find any legitimate emails, I add the sender to my bccexempt list so the mail will be delivered into my Inbox.

    Then I created a .qmail-safe file to handle the forwards where the legit email really gets sent to, and I have that dump into ./Maildir/ to deliver normally.

    The first month I had this in place, I received nearly 200 spams, and approximately 12 of those actually made it into my Inbox. This works so well because most spammers use BCC to send out their spam. This filter gives you control over who can BCC you. I know this doesn't stop spam at the source. I know it doesn't cut down on bandwidth usage. I know they can bypass it by mailing me directly. But I also know that there were 200 spams the first month that never entered my inbox.
