Timehop

Timehop operates as a social media memory application that enables users to view past posts and photos from their connected social media accounts. The service creates a daily flashback experience by aggregating content from the accounts users link to the platform. Users connect their existing social media profiles to Timehop to receive personalized reminders of historical activity. The company is headquartered in the United States of America. While the exact founding date and total user base are not disclosed in the available sources, the service is designed for individuals who wish to revisit their digital history.

In July 2018 Timehop disclosed a data breach that affected approximately 21 million users of the service. Among those, personal information including names, email addresses and phone numbers was exposed for about 4.7 million individuals. The intrusion occurred after attackers obtained compromised administrator credentials and used them to conduct reconnaissance within the company's cloud environment over several months. Data exfiltration took place during a holiday period, and the breach also revealed authentication keys for social media integrations. No financial data, location information or actual social media content was accessed, though the exposed keys posed a theoretical risk of token misuse for a limited window. Following the incident Timehop strengthened its security posture by enforcing multifactor authentication on previously legacy cloud accounts and enhancing encryption measures. The company engaged law enforcement and GDPR specialists, and notified affected users through in‑app messages and planned bulk email communications.
