Another Major Data Breach: Instagram Leaks Personal Information of 17.5 Million Users

A significant data breach has compromised Instagram’s security infrastructure, affecting approximately 17.5 million user accounts. The leaked data includes critical personal information—usernames, email addresses, phone numbers, and residential addresses—all of which have made their way to the dark web for sale.

What Information Was Exposed?

The scope of this data breach is extensive. Attackers now possess access to a comprehensive user database containing names, contact details, and location data. This combination of information creates a perfect storm for fraudsters, enabling phishing campaigns, account takeovers, and potential identity theft schemes targeting millions of users globally.

The Technical Root Cause

Security researchers at Malwarebytes have traced the breach back to an API vulnerability that Instagram failed to patch adequately in 2024. The Meta platform’s API exposure left user data accessible to unauthorized parties for an extended period. Such API misconfigurations are surprisingly common but often prove catastrophic when discovered by bad actors.

Evidence of the Breach Is Already Visible

Users have begun reporting suspicious activity on their accounts, most notably a surge in unsolicited password reset emails. These notifications serve as a red flag that their credentials are already at risk and that attackers have begun probing access attempts.

Meta’s Silence Raises Concerns

Despite the severity of this data breach affecting 17.5 million users, Meta has yet to issue an official statement acknowledging the incident or outlining a remediation plan. This lack of transparency is troubling for affected users seeking clarity and guidance.

How Users Can Protect Themselves

Security experts unanimously recommend immediate protective actions:

• Enable two-factor authentication (2FA) on all accounts
• Change passwords to strong, unique credentials
• Monitor financial and personal accounts for suspicious activity
• Consider freezing credit reports if personal data exposure is severe

The Instagram data breach serves as a stark reminder of why API security and regular penetration testing remain critical for platforms handling millions of user records.
