Couchsurfing Hacked, Sends Airbnb Prank Spam 44

Slashdot regular (and Couchsurfing.org volunteer) Bennett Haselton writes with a report that an anonymous prankster hacked the Couchsurfing.org website and sent spam to about 1 million members, snarkily advertising their commercial arch-rival Airbnb as "the new Couchsurfing." (Read on below for more on the breach.) As of now, the spam's been caught, but not the spammer.

I've been a volunteer host on Couchsurfing.org for 16 months. Despite the ongoing controversies surrounding the site's changes in recent years, I've always found it to be a great way to meet travelers with fascinating stories and to make new friends, not to mention a way to force a deadline upon yourself to clean up your house before the next guest arrives.

On August 15, I received an email sent from "Couchsurfing <noreply@couchsurfing.org>" with the subject "Site Improvements", which read:

Hi!

We have some exciting news. Find out more about the new CouchSurfing here.

The CouchSurfing team

but the hyperlink on the word "here" did nothing when I clicked on it. So I looked at the HTML source code of the message and saw that the source code of the link was: We have some exciting news. Find out more about the new CouchSu= rfing <a href=3D=E2=80=9Chttps://www.airbnb.com/signup_login=E2=80=9D> her= e </a>.

So... the email from Couchsurfing was promoting a link to their commercial arch-rival, Airbnb.

At that point I assume the message was spam that had been sent from some third-party server and simply forged a return address from couchsurfing.org, but the message headers clearly showed that the message really had been sent from Couchsurfing: Received: from messaging3.couchsurfing.com (messaging3.couchsurfing.com. [54.236.187.135]) by mx.google.com with ESMTP id v7si15118226qay.99.2014.08.15.21.30.16 for <bennetthaselton@gmail.com>; The complete message headers and message source are here.

I sent a message to Couchsurfing tech support asking if they knew what had happened, and I started a thread on the Seattle Couchsurfing page, where several other users chimed in that they had received the same email. Couchsurfing support replied to me on August 18th:

Hello Bennett,

Thanks for your patience while we have been looking into this. As you saw yourself, some Couchsurfing members received an email in error on Friday night -- we apologize.

The part of Couchsurfing’s system that sends email to members was breached Friday night and an email was sent to approximately 1 million members. We take this very seriously, and we will continue to investigate and take all appropriate action until this situation is resolved.

There is no action you need to take to secure your account. Once we have further information, we will be sure to send out updates.

Warm Regards,

Then on August 19th, I received an email from Couchsurfing (presumably along with all or most other Couchsurfing users) with the subject "Incorrect email -- our apologies":

Dear Bennett Haselton:

We're writing because you may have received an odd email from Couchsurfing in the last few days titled "Site Improvements."

We apologize for any confusion this may have caused -- it should not have been sent.

-- The Couchsurfing Team

Want more details? Find them here

where the "here" link further explains: "The message was sent by an unauthorized user of our email system. No other systems were compromised, and we've addressed the circumstances that led to this unauthorized use."

So, kudos to Couchsurfing for at least alerting users that something had gone wrong. (Judging from the reactions in the thread that I started, most users who received the email simply deleted it without a second thought after seeing that the link didn't work, so Couchsurfing probably could have said nothing to their users at all, and gotten away with it. As of this writing, a Google News search for "couchsurfing hacked" turns up no other articles about the incident, so it's not as if there was a mob clamoring for answers that they had to respond to.)

On the other hand, I hope Couchsurfing is more forthcoming in the next few days about how much they know about what actually happened. When they say "We've addressed the circumstances that led to this unauthorized use," that probably means that they at least know whether the email was sent by (a) a disgruntled employee (or recently fired employee whose credentials still enabled them to access the server); or (b) someone who used an unpatched security hole to break in from the outside; or (c) something else. (I replied to the tech support ticket asking as much, but as of this writing I have not received a reply. I wasn't naive enough to think that they were probably going to tell me everything they knew, but it's one of those rituals that quasi-journalists engage in so that we can say "as of this writing I have not received a reply".)

Obviously I think it's unlikely that anyone at the real Airbnb would actually risk jail time by hacking Couchsurfing's servers to send out spam advertising the Airbnb website; it seems more like the actions of someone being snarky, possibly a former employee or an outsider with an axe to grind. Couchsurfing's apology email said "Once we have further information, we will be sure to send out updates." Hope so.

      But the counter argument is that he clicks on links sent to him via email prior to verifying their origin (who sent them) or destination (where do they link to).

      Everytime he posts the only thought that comes to mind is ...

      OMG I DO NOT FUCKING CARE WHAT THIS IGNORANT MORON THINKS ABOUT THINGS HE UTTERLY FAILS TO UNDERSTAND IN EVERY WAY.

      This no different than every other instance. He's a moron who thinks people care what he has to say and thinks he actually knows what he's talking about. He's the worst kind of ignorant, too stupid to realize how ignorant he is.

      • I should also point out how he blindly clicked on a link in an email that should have set off red flags the instant he saw it.

  • ...and that means that their petty squabbles don't really affect me very much.

    It seems like most "new" things are just reimplementations of existing things. We haven't had something revolutionary on a software front in a long time.

    I expect that most technological revolution will be hardware-based for the next while and software will follow as a necessity, not as the driving force. Computing devices become wearable and less obvious (no more hulking PCs, that sort of thing) and eventually maybe the so

    I can't even think of how scary it must be to wind up on Bennett's couch. I can imagine a naïve traveller opening Bennett's door, finding no one there and deciding to make themselves at home.. only to hear the door slam and lock behind them. That's Bennett preparing to move in for the kill - but he won't do it yet, oh no, that would be too soon. He'll lie in wait until the traveller is at their most vulnerable, just when they've turned the lights off to sleep, wondering where the host is.. and that's when he springs out with a satanic, blood-curdling cry of "Hey, want to hear my thoughts on cellphone tethering and data plans?"

    The police will find the gibbering husk of what used to be a man huddled in a pile of trash in an alley a mile down the road, slowly rocking back and forth, chanting the same four words over and over: "He.. doesn't.. shut..up.."

    We cannot filter him like we can with editors. Please stop making Slashdot this boring man's blog.

  • Assuming he was hired by AirBnb, he is an idiot.

    If he had simply taken their client's emails he probably would have gotten a similar increase in business and no one would ever have been the wiser that he had hacked Couchsurfer.

    Instead this idiot made a statement, may end up in jail, and almost certainly will have pissed off any ethical Couchsurfer.

      Why change the data and join a group if the profile just gets deleted afterwards? I'm not sure if you're kidding or not :-)

      Besides, wouldn't this also require that all actions work through GET requests instead of POSTs?

  • Couch surfing at a stranger's home is like staying at a hostle or homeless shelter and is very risky to you and your belongings.

    On the other side of that, letting a complete stranger into your home to sleep on your couch is also risky and could get you robbed, hurt, and/or killed.

        People have been "robbed and hurt" on Couchsurfing, but beyond the rare petty theft that could even happen when hosting friends (yes, people's friends can steal too) or relatives (many people have a klepto in the family), violent incidents are rare and the cases I am aware of were single females unwisely hosting single males. I am unaware of anyone ever being killed. Maybe you would like to back up your assertion somehow?
