In a Saturday July 7 blog post, social media company Timehop publicly revealed a July 4 security breach that resulted in the personal information of approximately 21 million users being compromised, including names, genders, dates of birth, email addresses, and phone numbers. The attack also temporarily exposed the keys Timehop uses to authorize access to other social media services, though all such keys have since been deauthorized and are thus no longer an active security threat.
