Why are *.edu’s compromised so much?

When it comes to the problem of outbound spam, one of the experiences that I have, and this was reaffirmed at TechEd, is that the number one source of compromised accounts are educational institutions.  That is to say, whenever we have an outbound spam problem and have to hunt down where it is coming from, the highest number of these accounts are phished accounts/credentials from users at an educational institution.

Why is this?  Why does so much spam originate from universities?  Why don’t we see the equivalent in the corporate world?

I don’t know the answer.  However, I will put forth a couple of theories:

  1. Universities have more lax security regulations.  Higher education is stretched for funds and IT administrators just don’t have the time to enforce security updates, install A/V software, and/or they allow students to download all sorts of nefarious things (bit torrents, shareware, etc).  This software contains keystroke loggers or something similar which steals user credentials and sends them back to the phisher.  In other words, lack of security patching combined with users who takes risks is what contributes to the phished account problem.

  2. Universities allow games to run on their computers, and malware targets these games.  This is a theory I have and it is similar to (1) above.  One of the most commonly occurring worms in the home user world is the Taterf worm which targets user credentials for MMORPGs like World of Warcraft.  Taterf spreads via USB thumb drives and misconfigured network mapped drives.  Users trade their USB keys and stuff between each other, and this malware grabs user credentials.  Since many people use their email addresses as their login information, and passwords as well, phishers inadvertently started collecting email credentials as well.  A nice byproduct.  But the point is that students are the ones installing all sorts of games and not taking security precautions, resulting in the spread of malware.

  3. Students fall for phishing scams more often.  I have no evidence for this, but if students (or possibly staff and faculty) have a higher rate of spamming then that implies that they fall for phishing scams more often.  Spam in their inbox that says “Please click on this in order to ensure that you have the latest software” which really installs malware, or steals credentials, is the result of the phish.  Students may not have as much experience with computers and then once they hit school, they get one for free.  But with new email accounts comes new experiences that they are not familiar with, and hence, they fall for scams.

None of these explanations is really satisfying to me.  It’s possible that it is a combination of the three of them, and also others that I have not heard of.

  • Terry,

    The fragmentation of the networks (balkanisation) where Engineering (and other Science) depts. have own networks and do not come under control of Uni IT dept. This is for various reason mainly budgetary and historical (they had computer first etc.) and this means that the EDU domains have no one team in charge.

    Pob

    PS At least this is the case generally for UK. I assume that US is similar

  • Hey Terry,

    Love the blog, I get here by way of CircleID. That being said... I've been doing some heavy research (amateur) into the stats we have recently discovered here at ESET and with the Securing Our eCity program. It appears that there are some other factors which I'll be publishing blog articles on in the very near future. First of which - there is definitely some sort of educational tie-in. We show in one nationwide survey that there is a precedence for more educated people (Masters, PhD) to be victims of cybercrime in one of our surveys at nearly TEN TIMES the rate of high school grads. Recent data I've been poring through focuses on the doctorate level and what role the mobile life of a doctor / tertiary educated person might be playing into this.

    Other theories which some of the other researchers put forth were: "Educated people - that's where the money is" and "this can't happen to me" attitudes which might be prevalent within academia. But... all of those are simply guesses.

    Can't wait to grab the data for those. Feel free to ping me over on my blog and I'll send you an email when it's posted.

  • Hello.

    First of all I want to say that you have a great blog and I enjoy reading it. However I would really love if you could rephrase the following part: "all sorts of nefarious things (bit torrents, shareware, etc)".

    BitTorrent is a protocol, so there isn't any inherent link between its use and the nefariousness of the things downloaded with it. Check out for example http://www.clearbits.net/ (and you will find much more than just Linux distors, I assure you).

    Also, most (almost all?) shareware isn't nefarious either. There are a lot of great software distributed as shareware which made Windows what it is today (Total Command, WinZip, Paint Shop Pro, ...).

    Regards.
