In case you missed it, Yo is a surprisingly popular app that does one thing. It creates a list of your contacts, and lets you tell anyone on the list "Yo." So it's not exactly rocket science.
If it was just a silly app, though, that would be fine. However, three enterprising hackers from Georgia Tech found a flaw in the app. The loophole gave them access to phone numbers and let them impersonate other users.
Instead of stealing personal data, the hackers sent the following message to every Yo user: "I hacked Yo. Use hashtag #YoBeenHacked to talk about it."
The app's creator, Or Arbel, apologized publicly on a recent blog post.
“Once we learned about [the hack] we’ve assembled a team of engineers with the hosting company, and began solving it,” Or Arbel said on Medium. “Once the issue was resolved ([Friday] noon), we contacted the hackers and verified that the problems had been fixed. One of them is actually now working with us on improving Yo experience in other aspects as well.”
For a seemingly useless app, Yo has already received a million dollars in seed funding and has already been the victim of a widely publicized hack. What's next for Yo, and would you ever use it?
