Zendesk Hack Hits Twitter And Tumblr Users


Pinterest also affected by hack on young customer service software firm

Customer service software supplier Zendesk has been hacked, leaking email addresses of Twitter, Tumblr and Pinterest users.

Zendesk CEO Mikkel Svane admitted a hacker breached the company’s security this week, gaining access to support information of three customers.

Zendesk investigation under way

“We have an investigation under way and do not have the answer to every question,” Svane said in a blog post.

Hack“We believe that the hacker downloaded email addresses of users who contacted those three customers for support, as well as support email subject lines. We notified our affected customers immediately and are working with them to assist in their response.

“We are also completely committed to working with authorities to bring anyone involved to justice and make certain we fully understand what happened.”

Svane said the vulnerability that let the hacker in has now been patched.

Various reports confirmed Twitter, Tumblr and Pinterest were the three affected customers, after the companies sent notifications to their users. There was no indication passwords were stolen, but investigations are ongoing.

“As this process unfolds, we aim to update our customers in as transparent and timely a manner as possible about new developments,” Zendesk’s Svane added.

Zendesk has a host of big clients, including Vodafone, MTV and Yammer.

Twitter will be particularly unhappy at yet another security even impacting it. A host of high-profile Twitter accounts have been hacked this month, and the company itself admitted it had been breached, potentially affecting 250,000 users.
