Selena Gomez's Instagram Account Among Those Affected by Hack

(Bloomberg) -- Facebook Inc.’s Instagram said it found a bug that exposed people’s email addresses and phone numbers, which it quickly fixed, according to Chief Technology Officer Mike Krieger.

No passwords were exposed, and the photo-sharing app is working with law enforcement to prevent further fallout, Krieger said in a blog post.

Celebrities are concerned that their information may have been exposed. Earlier this week, Selena Gomez’s Instagram was deactivated after it posted nude pictures of Justin Bieber, her ex-boyfriend. She has Instagram’s most-followed account.

Instagram believes a small percentage of accounts were affected, though it is unable to identify which specific accounts were compromised. The company didn’t immediately respond to further questions.
