Even My Mom Could Hack These Sites

Frequent Slashdot Contributor Bennett Haselton's latest story is ready for your consumption. He starts "Recently, as an experiment, I wrote from my Hotmail account to ten different hosting companies that were each hosting some of my Web sites, asking for logins to change the domain settings. Even though I never provided any proof that the messages from the Hotmail account were really coming from me (the address they all had on file for me was a different one), half of them replied back and gave me the logins that I needed."

I figured that if I wrote to them saying "I forgot my password, please mail it to me," that would be too obvious. Instead, at the time I had set up shop with these hosting companies, I entered a domain name at the time of creating my account, and asked them to register it on my behalf (long before I had this experiment in mind). Then when I wrote to them recently from my Hotmail address, I sent each of them a message saying: I need to transfer this domain somewhere else, can you give me the login at the registrar where you registered the domain, so I can change the domain settings. Five of the ten companies either (a) gave me the registrar login, (b) transferred the domain to my registrar account on request (even though I never provided any proof that the owner of that registrar account was really me, either), or (c) changed the domain to point to a new IP address that I specified -- all of which, of course, would allow an attacker to take over a site temporarily or even permanently, if it hadn't really been me writing from the Hotmail address.

But slow down before you go off to try this out on Yahoo, eBay or Google hoping to get the same 50% success rate. First, these were all low-budget hosting companies, so the people handling my queries were likely not highly trained professionals who would have developed all the right habits about when to get suspicious. Second, this ruse only worked because the hosting companies registered the domains on my behalf. Most sites that are really worth taking over, are hosted on dedicated servers, and this trick wouldn't work on a dedicated hosting company because they usually don't register domains on behalf of customers; they assume that anybody buying an expensive dedicated server, knows enough to buy the domain and point it at the server that the company gives them.

But even for small-time hosting, a 50% success rate for a trick like this is uncomfortably high. So what can we do about it? Well, every problem has a non-solution that requires changing human nature ("People should just stop buying from spammers and they'd go out of business!") and a non-solution that ignores the economics of the situation ("ISPs should devote more resources to stopping spammers on their own network!"). In this case, the corresponding non-solutions would be (a) "People who work for hosting companies should be less gullible" and (b) "ISPs should hire smarter people, without charging more to their hosting customers".

The solution that doesn't require any cheating, though, is to have procedures in place for anything remotely security-related, and drum into employees' heads that they have to follow those procedures. Here's some good news: Of the five companies that fell for the ruse asking for my registrar login information, when I followed up with them saying "Hey, I forgot my account password, can you mail it to me", only two of them actually sent my password to the Hotmail account. To those two, I replied with some terse words about having a six-inch-thick steel door while leaving the window wide open. But at least it was only two out of ten that fell for that ruse, compared to five out of ten that fell for the registrar trick. The difference is that hosting companies have procedures in place to deal with password resets -- a script that sends the existing password, or sends a reset-password link, only to the customer's e-mail address on file.

Similarly, any hosting company that registers domains on behalf of users, should have procedures in place for transferring the domains to users or letting them change domain settings. In fact, of the five companies that didn't fall for the ruse, most of them said "Go to the customer control panel here and log in" -- it wasn't that their guard went up because I was writing from a Hotmail account, it was that they already had procedures in place for a customer wanting to change domain settings, and what's what the idiot-proof book told them to do. Kevin Mitnick always said that the weakest link in any security chain was people. Sometimes the way for ISPs to tighten security is to make the people in the chain act more like machines.

Until then, there are probably many sites out there that are this easy to "hack", using a method that could charitably be called low-tech. After seeing which hosting companies fell for the trick, I pointed out that they had sent the login information to an unverified address and admonished them to be more careful in the future, but I didn't storm out vowing to take all of my business elsewhere -- after all, if 50% of all low-budget hosting companies out there fall for this, what would be the point?

    As a 48 yo grandmother, I am offended that technical incompetance is equated with being a mother. I don't think anyone would have said "even my dad could hack these sites".

    My boss still refers to AOL as "the Internet". I was finally able to force her to upgrade her windows 98 machine. as I setup XP and firefox I set firefox's icon to that of AOL's, set the Homepage to www.aol.com and changed the icon's name. I installed aim. She is annoyed that the "new" aol isn't quite the same as the old one but is dealing with it.

    never underestimate a person's unwillingness to learn something new.

    It's obvious that you're a C programmer, since a C++ programmer would have immediately recognized the difference between a class and an instance of that class.

    He could just as easily have called up, claimed to have "just got back from holiday and forgotten my login details" and given Sarah his boss' name. 30 seconds later, he's got his boss' user ID and the password reset on the boss' account.

    Maybe I'm "retarted"...but I thought that's exactly what the guy did. That was the point of calling from his boss' phone, right?

    It's funny though how if the poster had said "Even a [insert any race here] person could hack these sites" it would be a completely different kettle of fish that would probably see people fired and a national outcry over racism.
