Examining an Automated Spam Tool 415

Saint Aardvark writes "SecurityFocus has published an excellent column detailing how spammers r00ted an Apache server, and used it to send spam. The tool they used is (I hate to admit it) pretty sophisticated: it has macro capabilities, picks up email addresses from and reports success or failure to the master server. It's a very frightening read...and so is this: Message Labs reports that they now intercept 27 spam emails per second, up from 2 per second this time last year. Virus-created proxies are mainly to blame."

        I totally agree. While I really hate the spammers I think I might hate the people that actually buy stuff from spam a little bit more.

        If you think about it, there are some really intelligent spammers (even though they are disgusting scum of the earth). They're always one step ahead of us and are figuring out new ways to spam us.

      Jokes aside, while not being compromised myself I have gone through a similar process investigating distributed server farms on cable and DSL serving counterfeit software (once again advertised by SPAM). In all cases the final step ended up being somewhere in Russia at least 600km from of Moscow.

      The method of intrusion is different though. In all cases it is windows software. Common examples are the one which copies DVDs to CDs (with all offers seen over the last 2 months being a trojan). Basically this, along with several similar common SPAM sucker gatherers is used for guess what - to gather suckers. The software actually works, but it contains a fairly sofisticated remote access trojan.

      This has recently been extented to include sucker gatherers introduced in counterfeit branded software. Basically, you pay 39$ for a counterfeit Win XP pro at "OEM Clearance Sales" and get a Win XP pro with a "surprise".

      Servers are all over the world, mostly on cable networks (strangely enough very few DSL ones). DNS (which is the weakest link) is run by known "questionable" marketing hosting sites usually in the US.

      With the number of suckers around trying to copy DVDs onto CDs frankly I do not see a reason for all the effort into hacking sites with vulnerable lame PHP software. So I guess these were some "new kids on the block"

      How come the idea of e-stamps is not getting any traction? The concept is that you are assessed a small charge for sending unwanted mail.

      I dont see what the technical or social barriers are. For example, it would not require any change in the way mail is transported. Instead it would all be handled by the recipient's browser.

      consider the following straw man scheme. I send you an e-mail.
      1) If I am in your white list the e-mail is accepted.
      2) if not then the e-mail is examined for a signed, serial numbered e-stamp and if present a short message is sent to central post office to debit the senders account one penny, and a receipt is returned to my e-mail program which then lets the message in.
      3) Finally if the message does not contain a stamp and is not white listed, the message is put in a spam folder and a memo sent to the sender (me) telling me that I need to request permission to send e-mail.

      The last step is how for example Earthlink's highest level spam blocker works. If most messages are spam then of course it doubles the total number of messages sent, but does not double the total message sizes or hand shaking. To the extend that it works, the post offices will only be consulted if the sender is not in the white list so unused stamps can be reclaimed. Moreover one could have the option of refunding the senders stamp if the message were welcome.

      I dont see what the sociologocal or technical hurdles are. Not every one has to be using the stamp processing client program. When stamps are not present it defaults to the earthlink system. When they are is skips that nuiscance.

      the best part is that legitimate direct mailers might very well be willing to pay the postage to send you an advertisment but presumbaly in many cases these would be targeted ads to people with potential interest.

      Yes. It needs to be completely blocked at backbone routers, and new and better alternative developed.

      So, the steps would be
      1. develop a better alternative as fast as possible, and make it as simple as possible to implement.

      2. deploy the better alternative for test use.

      3. develop a fixed version 2 of the better alternative after it's holes are discovered.

      4. deploy the fixed version.

      5. block SMTP and version 1 of new protocol at international and national backbones and national borders, so that everybody is forced to switch.

      So SMTP would still be completly usable for example inside organizations, so if a company has huge installed base of legacy software, they could have internal SMTP-new protocol gateway.

      Of course this would require IETF to get their act together, and various governments to agree that this must be done, and actual new protocol to be simple enough and not contain patented algorithms or any other stupidities.

      So it will not happen. Then spam will overwhelm the internet transfer capacity. Then SMPT is blocked and free internet e-mail will cease to exist. Proprietary solutions will develop, but there will be a chaos. Incidentally, Microsoft will happily provide a closed proprietary system only usable from their operating systems.

    Other trends started this year and expected to increase in 2004 include the use of e-mail to trick people into going to what they think is a legitimate vendor's web site and provide confidential information, such as social security or credit card numbers, MessageLabs said.

    Although I haven't experienced spam that goes so far, I have received (in my special spam account for playing with Nigerians and lottery managers) quite a few mails with requests to confirm my e-mail address. It works like this - you get a mail saying something a la: "I am controlling the e-mail sent to my inbox for the following address: sucker@born.every.minute.com. By asking for you to confirm that you really sent email to me I can ensure that I receive no spam and that your email address really exists. This is a one time confirmation, please click the link below and your email will be delivered straight away, now and in the future. Regards, Alberto Huber"

    The funny thing about it was that the "I" in question was neither someone I sent mail to nor someone I know at all.

      Here's an idea, tell me why it won't work. :)

      Instead of having one mail server for your home or organization, you have two. Except one is secretly useless. It just blackholes everything that's sent to it.

      You buy another domain and list the blackhole as the MX record for the new domain.

      You sign up for a bunch of email marketing lists using addresses from the blackhole domain.

      Everything that gets sent to the blackhole server is by definition spam.

      The blackhole server also runs DNS. You set your real mail server's RBL DNS to point to the blackhole server.

      Every time the blackhole server accepts a connection on port 25, the blackhole server immediately drops the connection (so no wasted bandwidth) and updates DNS with the originator's IP address.

      You now have your own local blacklist, you don't have to trust somebody elses. Keep a log, if somebody bitches about it you can say "Well, somebody sent spam to my blackhole server on this date at this time from your IP. Suffer".

      You'd have to combine it with a whitelist to let Yahoo and Hotmail and so on through, but you'd still kill a lot of spam.

        Here's an idea, tell me why it won't work.

        OK, but remember, you did ask.

        First of all: what you envision is nothing new. It's called a 'spamtrap'.

        The most important thing is that it relies on security through obscurity - as soon as the spamtrap addresses become known, they're useless (and can actually be used to fsck you up.) If you think this won't happen, I urge you to read the article - this spam machine isn't stupid, and will find your spamtrap addresses faster than you think.

        Every time the blackhole server accepts a connection on port 25, the blackhole server immediately drops the connection (so no wasted bandwidth) and updates DNS with the originator's IP address.

        Pretty simple - anyone who knows the spamtrap address(es) can now DOS your legitimate mail server by sending mail to your spamtrap. (I realize you noted this, but included only Yahoo and Hotmail.)

        Spammers get your spamtrap address, they have infected machines on many different ISPs, so they send mail to your spamtrap using those ISPs' (again) legitimate mail server.

        Congratulations, you have just stopped receiving email from every ISP on the planet.

    yes it's definitely profitable, this is part of the problem, a major part of it!

    even with all the crap that people are doing, new SMPT clients, new RFCs and bullshit, it's not going to work!

    why? because spammers pay their ISPs tens of thousands of $ a month just for the privilege of spamming!

    I remember an old story months (or years) ago about a spammer, got tracked down, the whole nine yards, the ISP refused to cut them off because they were paying the ISP over $50,000 a MONTH to send spam. These days they pay even more.

    So all your "checks and balances" don't do any good, because the spammers are VALID users (at least in the eyes of the ISP hosting them).

    And this is also why no one does egress filtering. AT&T US, etc won't do it because they get PAID to keep sending the stuff...

    face it, spam is BIG business, it makes millions, esp for the ISPs, etc.

    all your useless "valid" client checks, checksums, special SMTP servers, blah blah blah won't make a damn of difference.

    the only way is with either good (huge) blacklists or bayesian all over the place.

    and what someone said about "end users" not caring about bandwidth usage, not true. I'm an end-user, and I care, excess bandwidth costs me money dammit! I am my own mail server, so don't tell me a firewall on my server is gonna slow down the traffic. it doesn't.

    I keep to my original proposal, a massive blacklist. headache? yes, but it'd work if kept updated...
    • as a end user,you are an excetption not the rule.

      never work, becasue A)some spammers are a legitimate ISP customer. You cu of that ISP you cut off al the non spamming emails.

      also, there is no insentive to spend the money to keep checking its validity all the time.

    • There was a great article in the local paper about how many ordinary businesses collecting email supposedly for customer service purposes are selling this info off, where it ultimately gets into the hands of spammers.

      Because SPAM as a whole is becoming illegal in many areas, and much of what spammers do is already illegal. If the ISP is allowing the spammer to continue operation, and he is pumping illegal products/scams/etc then the ISP will be on the line.

      It's one thing to profit for unscrupulous activity, it's another to knowingly allow an illegal one.

      Making it easier to certifiably track spammers is part of the solution because if you can say with strong surety that an ISP is supporting the spammer... then you can take action against the ISP.
    • No, you are wrong. The real solution involves a multitude of changes. It requires blacklists, filters, open relay blocking, client verification, legislation and possibly other fixes as well.

    This is going to make me move my web server to OpenBSD 3.4-stable on macppc even sooner. It would have two layers of defense against this kind of attack, even if the PHP hole was there.
    1. Chrooted apache means that necessary shared libs/utility apps for the binary aren't available immediately.
    2. PowerPC processor means that i386-binary payloads won't run

    Running under systrace might also help stop it from opening outbound connections.

    • OpenBSD on SUN hardware is even better: Sparc chips have built in executable protection.

      Sparc hardware nativly allows processes to set chunks of memory as "allow code execution, but don't allow self-modifying code".

      Unfortunatly curent x86 hardware lacks this feature without a lot of work.

      And then I suppose that once the basic spamming infrastructure is established and paid for by that, there's ready market for getting other businesses and plain scammers to do spam marketing, thus increasing spammer profits more and pushing down the price per email.

    I have 2 questions that I have always wondered:

    1. Most spam mails are selling something physical and are actual companies; why can't they therefore be tracked down and slapped with lawsuits easily?

    2. Why doesn't user education work? Maybe a mass education campaign towards users will make the spammers give up - I agree there will always be the odd idiot, but if 99% of users are educated, just like most kids know not to talk to strangers, there will eventually be a decline in such?

      1. Because it's usually some spamming company performing the spamming, not the real company. They only hired their "PR services", in which case you have to prove they did know it their marketing practices would be illegal.

      2. No, 99% is not enough. A 1% response rate would be insanely high. Even a 0,01% response would easily be enough. Because it costs next to nothing, with next to nothing in risk.

      To pull on your "99% of users are educated, just like most kids know not to talk to strangers" analogy, it wouldn't work if the pedos could ask thousands of children simultaniously (i.e. no cost of time) and none of those that refused would report it. Who cares if 990 turn you down, if you can have a 10-kid orgy every day? Sounds awfully cruel, but that's the way spam works today. They pray on the few stupid enough, and hope that the great majority will simply hit 'delete'.

    You can fix this problem by catching attempts to modify the $GEEKLOG_DIR file via get or post methods at the top of the gallery/classes/geeklog/User.php file. Insert this line:
    if (isset($_GET['GEEKLOG_DIR']) ||
    isset($_POST['GEEKLOG_DIR'])||
    isset($_SESSION['GEEKLOG_DIR']))
    die('nice try buddy.');
    }
    The $GEEKLOG_DIR variable is actually set at the end of the gallery init file, so it should not be coming from any other directories. This is another example of why it's bad to leave register_globals on, as the whole problem could have been avoided otherwise.

      This is another example of why it's bad to leave register_globals on, as the whole problem could have been avoided otherwise.

      Except.. it wouldn't have, in this case at least. Gallery works with register_globals turned off, I just checked.. but then I noticed the code (this is in init.php if anyone wants to check):

      if (!$gallery->register_globals) {
      if (is_array($HTTP_GET_VARS)) {
      extract($HTTP_GET_VARS);
      }

      if (is_array($HTTP_POST_VARS)) {
      extract($HTTP_POST_VARS);
      }

      The extract() function [php.net] basically takes everything from the _GET and _POST arrays and dumps them straight into the appropriate variables, which is exactly what register_globals does. Whether it was turned on or off, you would still be able to pollute the $GEEKLOG_DIR variable via get/post. This is a pretty braindead piece of coding right here, and makes me a little worried about using gallery. I hope they plan to fix this in the future.

    In my dorm we have blocked port 25 from LAN to internet. It was thought to keep viruses from propagating from out network and keep people from setting up a spamserver. Now it looks like a very good decision. (they can actually only use our DMZ smtp gateway, which is antivirus protected).

    All ISP or the like should block port 25 outbound by default, and make people use the smtp server of the ISP. If people (1 out of 10.000) would like to use port 25 outbound, they should contact the ISP through a bureaucratic procedure. That would close the trojan hole at least.

    Are there any other ports (priviledged/unpriviledged) that one can safely block to avoid trojans and the like???
    • by tgd ( 2822 ) on Tuesday December 09, 2003 @04:30PM (#7672885)
      To do that ISPs need to allow SMTP authenticated users to send e-mail with any domain name attached.

      I have to run my own e-mail server, because Comcast (my cable modem provider) doesn't allow me to send outgoing e-mails with my real e-mail address, its go to be @comcast.net or whatever their domain is.

      If they block port 25, e-mail is effectively shut off for me as a usable technology on the Internet, and I'll be stuck either having to tunnel the e-mail to someone who doesn't have it blocked, or change ISPs.

    Let's first of all say I am no fan of spam. In fact, I hate it. All spammers - and virus writers - should be strung up and subjected to some real virii.

    However, some of these statistics are possibly obscuring reality. For example, let's take Messagelabs anti-spam service. Until recently, all emails from WorldPay - receipts, etc. - were marked as spam. All the traffic on an email discussion list that I have signed up for are marked as spam. Some commercial email notification lists that I have signed up for (ie. Maplin offers) are marked as spam.

    But none of those emails *are* spam. Admittedly, some spam emails do get through without being flagged. So maybe it's a bit 'swings and roundabouts'. And regardless, the situation is pretty depressing anyway.

    One thing I have been thinking about - and just wondering whether it should be entered as an Ask Slashdot item - are some of the 'cures' as bad as the problem itself?

    I work on biology / medicine journals websites, and we offer a number of automatic notification and general update services. Note that these are *not* spam - they are requested by individuals by signing up on the website - and instructions are given in every email in how to remove yourself from the list. And they are a very valuable service to many people that do choose to receive them. Yet it only takes 1 person to not bother to read or follow the removal instructions, or otherwise hit some other temporary (accidental) issue that holds up their removal, and then submit it to a blacklist service to bugger things up for many other people.

    So where is the regulation on the blacklist services? Where is the ability for *genuine* (provably genuine) companies to register their services in such a way that rather than getting blacklisted immediately, they have the opportunity to respond to the issue raised? Is this a small or large price to pay to partially stem the tide of actual spam?

      The market regulates it. A blacklist that is too aggressive doesn't get used. It's really that simple. If your ISP blocks stuff you don't want blocked, compalin to them, or switch. If someone's blocking your mail, it's up to them to complain to their ISP. If they don't, they obviously don't object.

      Where is the ability for *genuine* (provably genuine) companies to register their services in such a way that rather than getting blacklisted immediately, they have the opportunity to respond to the issue raised?

      Most mail admins don't give a flying fuck whether you are a "genuine" company or not. I got spammed relentlessly by American Express, until I block their entire IP block until the heat death of the universe. If you don't want to be blocked, don't spem. It's not that difficult. Really.

    Checking the satellite imagery [keyhole.com], that's a tract house backing up to a six-lane highway. It's not a mailbox service.

  • The overwhelming amount of spam I get now involves the advertising (and presumably selling) of a controlled substance--a prescription drug that is deemed a narcotic. The prescribing of this drug (and a few others in the spams) by legitimate physicians, and its dispensing by legitimate pharmacies are strictly regulated in some kind of effort to prevent the abuse of the drug--an abuse that is rampant in many areas of the US.

    I keep waiting to hear that the Federal authorities have taken some action in this regard. If you've ever been through US Customs (and especially if you're young, not white, or in any way "unusual" looking) you'll know that they make a great show of looking through everybody's sneakers and dirty laundry on the hunt for "illegal drugs." Even in these times of terrorism, it's their chief claim to fame.

    The potential for abuse seems enormous and growing to me. It also seems to me that a lot of the spams advertising this stuff originate in, or pass through, the U.S. If somebody in our town hung out a sign saying GET YOUR PRESCRIPTION NARCOTICS HERE--NO PRESCRIPTION REQUIRED, my guess is the police would take an interest. But we seem to have virtual open-air drug markets operating undisturbed.

    If anyone wonders how spammers make money, this is certainly one possible way, and I suspect it's incredibly lucrative.

    4. What's an easy way in Linux to tell if your outbound bandwidth is slammed?

    I was very impressed with the forensics this guy did. It was fascinating. Too bad it's necessary. I wonder how many machines out there are compromised without anyone even knowing it.

      1. Technically no, the spammer never got root. The spambot was sending spam as an unprivileged user (the same one that Apache ran as), which is still plenty to run a spambot.
      2. Any user can chmod files that he/she/it owns, even to deny him/her/itself access and then chmod it back.

    * Make every stupid person smart so noone responds to spam

    * Change every mail server in the world to use a new protocol

    * Use client-side spam detection to hide spam and expect the stupid people to use it

    Well, I have less than complete faith in any of these methods providing an adequate short term solution. So, why cannot we look at the big picture?

    A few major spammers are sending millions of emails. The effect is close to being a DoS attack on the entire Internet. These emails are susceptible to pattern analysis if analyzed on a global basis. Surely what we need is somethng akin to an Internet-wide intrusion detection system. When pattern analysis indicates a spam attack, we simply block the traffic as close to the source as possible.

    Wouldn't there be a cost associated with this? Sure. But the spam problem needs to be resolved and this is the only realistic short term solution that I can envisage.
