**Instagram Denies Data Breach After Surge in Unsolicited Password Reset Emails**
Meta-owned Instagram has refuted claims of a data breach following reports that millions of users received unsolicited password reset emails. The company confirmed that an external party exploited a bug to trigger mass password reset requests but emphasized that no unauthorized access to user data or backend systems occurred.
The incident began when users reported receiving unexpected reset emails, sparking speculation of a large-scale breach. Cybersecurity researchers later claimed a dataset containing details of 17.5 million Instagram accounts including usernames, email addresses, phone numbers, and some location data was being sold on underground forums. However, Instagram stated the dataset likely stemmed from past scraping incidents rather than a new breach.
A Meta spokesperson clarified that the issue had been resolved, assuring users that their accounts remained secure. While no evidence of a system compromise was found, the company advised users to disregard the emails and avoid clicking suspicious links. Instagram is investigating the origin of the dataset but maintains that no new breach occurred.
