WP Engine Identifies Cloud Infrastructure Provider as Entry Point for Recent Security Breach


On December 9th, 2015, WP Engine sent out an urgent notice to its customers regarding a security breach wherein customer credentials were exposed. This incident prompted an investigation, which is now complete.

According to the most recent and final update, investigators determined that the security exposure came through one of the host’s cloud infrastructure providers. Customer credentials were exposed on December 4th and detected by WP Engine on December 9th. At that point customers were notified, the investigation was launched, and customer credentials were reset as a security precaution.

“WP Engine was attacked by an external criminal whose point of entry came through one of our cloud infrastructure providers,” founder and CTO Jason Cohen told the Tavern.

“An investigation by our own security team and independent security experts revealed the attacker bypassed multiple layers of authentication and gained unauthorized access to an administrative panel provided by this infrastructure provider. The criminal’s behavior in this exposure matches a pattern seen in other attacks throughout 2015,” he said.

When news of the breach was first published customers expressed frustration about the host’s lack of two-factor authentication. However, Cohen said that 2FA would not have made an impact for those affected by the recent security breach.

“Because the point of entry wasn’t one of our systems, 2FA would not have prevented this event,” he said. “That said, 2FA is a best-practice, and so we do have plans to roll out 2FA in our User Portal in early 2016.

“We also recommend that our customers enable 2FA for their WordPress site using one of the following recommended plugins: Google Authenticator or Clef, or use an external authentication system such as Google OAuth,” Cohen said.

WP Engine contacted the companies that were directly impacted by the attacker and implemented a plan to ensure their security. The independent investigation is now complete, but WP Engine continues to work with law enforcement authorities who are conducting a criminal investigation.

    • I realize the breach happened at the “cloud provider,” but a very similar incident happened 2.5 years ago, and WP Engine was a lot more transparent with who their provider was (Linode).

      I’d love to see them be more transparent (unless, of course, it’s for legal reasons, but I have serious doubts that’s the reason).

      I’m 99% sure they still use Linode. They are listed on Linode’s website as a partner, and Lincode confirmed their recent data breach (here).

  1. When did “managed hosting” with “best-in-class customer service” turn into not-managed-well hosting with customer service that fails not once, but twice, within a month’s time – and then it’s always someone else’s fault. (Linode, Cloud Infrastructure Provider). If this was cheap shared hosting, I’d understand, but expensive managed hosting? Ugh.

    • Hi Donna,

      I don’t work for WPEngine, and I can’t speak specifically to your customer service experiences, but I can tell you that infrastructure, cloud or otherwise, problems are something that every single hosting provider has to contend with. I can’t think of a hosting provider, shared or otherwise, who can give you hosting for less than $50/month for a single site and do it on their own infrastructure that isn’t rented/leased from somewhere else. You, as a person, could totally go get a dedicated server from somewhere like Hurricane Electric, and expect to pay several hundred bucks a month just for that server, and be in charge of maintaining the entire stack. Linode is having troubles now, and it’s massive, but the same thing will happen to Amazon and any of the other big cloud providers. Sort of the nature of the beast.

      • To me it reinforces my belief that it’s not worth paying for ‘premium’ managed WordPress specific hosting in the expectation that it will spare me various security/infrastructure issues. Barring a few really bad hosting companies, generally you get a decent enough experience with similar exposure to risks/downtime etc.

        • Hi Peter, it’s true that both managed and unmanaged hosting can have the same sorts of problems. The difference is what happens when those problems arise.

          Using this incident as the example, if you were in this position as your own sysadmin with your own VPS, you would need to hire and manage an external security firm (which we did, but we have an internal security team who could do that), you would need a lawyer to work with the authorities (which we did, but we have in-house council), you would need to perform diligence on an investigation and any remediation, and more things which sadly I’m not at liberty to discuss here.

          In the case of managed hosting, we did all of that on behalf of our customers. That is a substantial service.

          Of course, it’s small consolation that it’s “a service,” considering that even better would be to not have the incident at all! So it’s not like we’re patting ourselves on the back — it’s simply doing the right thing.

          But, to your point, it can (and does) happen to anyone, and only in a managed environment will the vendor take care of that for you.

        • Peter,

          While many will see this as a complete joke, but my primary site is still being hosted through Hostgator and other than a few snags here and there, I have not had any issues like what I have seen from companies who are providing pricey Managed WP Hosting solutions.

          Of course the other company that I feel very comfortable with is InMotion hosting. They seem to have a very knowledgeable staff when it comes to any issues with WP.

          However, most of the larger companies are owned by IEG, but as long as my sites are up and running, I think I’ll stay with the ones that most people seem to talk bad about. They haven’t done me wrong yet!

    • Hi Paul, while we still can’t talk about the nature of the breach due to the on-going investigation by two US Federal authorities on their cases, I can answer the question about why we required so many password resets.

      When we first became aware of the incident, we elected to inform our customers as quickly as possible, rather than wait for a full investigation to complete (which can take weeks), during which time our customers would be blissfully unaware.

      Because we informed as quickly as possible, we couldn’t yet know exactly what data was involved, or even any details of what had or hadn’t happened. Therefore, we took the maximum precaution and elected to roll *all* passwords, even though in retrospect you could argue that not all of that activity was strictly necessary.

      While that caused work for our customers, and of course hurt us in the press, it was the right thing to do for our customers’ safety and knowledge.

        • Hi Rick, as stated in the article above and in our own public report, we indeed have contacted and spoke on the phone with every one of our customers who were directly impacted, so you’re right about that, and we’ve already done that.

          What’s not appropriate is to reveal information that could compromise the investigation by revealing what is and isn’t known about the criminal. This is true in many types of legal investigations, not just in security matters, and we will adhere to industry and legal guidelines in this matter.

      • I actually agree with your decision to reset passwords. Yes, it involved some work, but far less than it could have been if the situation had progressed. When I saw the notice, I was actually impressed. The ability to rapidly refresh security settings is actually a plus in my mind as well as an absolute necessity in today’s world.

  2. Does WP-Engine own their own datacenter, housing their own hardware and staffed by their own people? Or are they simply buying “time and space” on a service like Amazon AWS or Rackspace or RagingWire might offer?

  3. Apparently, this attack is straining WPE resources. I have a client whose site went down with 502/504 errors on Saturday, and only was back up today at noon after rolling it back, and it’s still not 100%. They have a dedicated server and of course pay a hefty premium for their service, and I still haven’t gotten an explanantion.

  4. WP Engine had a rough month with their infrastructure provider between the data breach and the massive DDoS attack this week against Linode. Losing their entire Atlanta data center and having all our sites offline for the better part of 48 hours straight was painful, no doubt.

    Personally I’m grateful that WP Engine is on the job when things go sideways like this. Changing all the passwords across all our hosting accounts is a hassle. But having cleaned up hacked websites for clients I know full well that the hassle of sorting through mass password changes is far less than dealing with a slew of hacked sites. And that would have been a very likely scenario if they’d been more worried about appearances than the security of their customer’s accounts.

    Their willingness to own up to the problems and provide solutions moving forward builds trust and makes me more inclined to stay with them rather than moving to another hosting provider.
