Zendesk Compromised; Twitter, Tumblr and Pinterest Users Affected

Trailrunner7 writes "In the wake of high-profile compromises of companies such as Facebook, the New York Times, Apple and others, officials at Zendesk, an online customer support provider, said that the company also had been compromised and the attackers had made off with the email addresses of customers of Twitter, Tumblr and Pinterest, all of which use Zendesk's services. All three companies sent out emails to affected customers, notifying them of the incident and warning that their email addresses may have been compromised. In what has become an almost daily occurrence now, Zendesk officials posted a notice on the company's blog with the heading "We've been hacked". The Zendesk hack notice says that the company became aware of the attack on its network sometime this week and that the company then identified and patched the vulnerability the attackers had used."

      I think it's mostly phishing attacks. It's really unbelievable the number of people who fall for that shit.

      Our organization has about 3,500 email users and every once in awhile a phish campaign will make it through our filters to a large portion of the user base. Without fail, a dozen or more users will fall for it and have their accounts used to pump out spam. What's maddening is that the same individuals continue to get phished over and over, even after repeatedly being educated not to ever give out their passwords. They see some tech-jargon looking email and their brain just shuts down. I'm at an enterprise full of generally intelligent folks - I can only imagine what's going on in the brain of your average Yahoo user.

      One of the funnier and somewhat more subtle compromises we experienced was a spammer who targeted our corporate webmail interface. He phished several accounts but didn't directly send spam like most of them do. Instead, he logged in via webmail and placed various porn and boner-pill advertisements in those accounts' signatures. As a result, some of our employees were unwittingly sending out porn ads appended to their legitimate business emails for awhile...

      More like companies like Twitter, Tumblr and Pinterest outsourced their customer support to Zendesk. Basically, they pay Zendesk to provide support services. You might have seen some support websites hosted by other companies to provide stuff like knowledgebase and other support information, including stuff like ticket tracking and such if you require support.

      For stuff like that, you have to create an account so your tickets and issues can be resolved.

      Yes, companies can do it themselves, but it's often trickier if you want to support stuff like downloads, knowledgebases (which require extensive search capabilities), support ticketing, etc. A lot of companies farm it out to let someone else worry about the software and hosting.

      In which case, I stand by my original statement...if Twitter, Tumblr and Pinterest users have had their data compromised, then it is wrong to refer to them as "customers" of either Twitter, Tumblr, Pinterest or Zendesk. Zendesk's customers are Twitter, Tumblr and Pinterest, and those services' customers are their advertisers.

    Incidents like these are why we need laws with real teeth to restrict the dissemination of private data. Zendesk should be facing a hefty fine for its negligence in this case. In almost all cases, these hacks are the result of failing to take basic security precautions that have been well-known and understood for years, if not decades. The next time someone loses a list of plaintext passwords from a database (which they should have never stored to begin with), fine them a million bucks or 10% of their gross profit for the year, whichever is greater.
