Nostalgic social network ‘Timehop’ loses data from 21 million users

July 9, 2018 TH Author

A service named “Timehop” that claims it is “reinventing reminiscing” in part by linking posts from other social networks probably wishes it could go back in time and reinvent its own security, because it’s just confessed to losing data describing 21 million members and can’t guarantee that the perps didn’t slurp private info from users’ social media accounts.

“On July 4, 2018, Timehop experienced a network intrusion that led to a breach of some of your data,” the company wrote. “We learned of the breach while it was still in progress, and were able to interrupt it, but data was taken.”

Names and email addresses were lifted, as were “Keys that let Timehop read and show you your social media posts (but not private messages)”. Timehop has “deactivated these keys so they can no longer be used by anyone – so you’ll have to re-authenticate to our App.”

The breach also led to the loss of access tokens Timehop uses to access other social networks such as Twitter, Facebook and Instagram and the posts you’ve made there. Timehop swears blind that the tokens have been revoked and just won’t work any more.

But the company has also warned that “there was a short time window during which it was theoretically possible for unauthorized users to access those posts” but has “no evidence that this actually happened.”

It can’t be as almost-comforting on the matter of purloined phone numbers, advising that for those who shared such data with the company “It is recommended that you take additional security precautions with your cellular provider to ensure that your number cannot be ported.” Oh thanks for that, Timehop. And thanks, also, for not using two-factor authentication, because that made the crack possible. “The breach occurred because an access credential to our cloud computing environment was compromised,” the company’s admitted. “That cloud computing account had not been protected by multifactor authentication. We have now taken steps that include multifactor authentication to secure our authorization and access controls on all accounts.”

All of which leaves users in the same place as usual: with work to do, knowing that if their service providers had done their jobs properly they’d feel a lot safer. ®
