TL;DR
Security firm Malwarebytes says account details for about 17.5 million Instagram users were found on the dark web, linked to an earlier API exposure. Instagram (Meta) says there was no breach, that it fixed an issue enabling external requests for password-reset emails, and advises users to ignore unexpected reset messages.
What happened
Over the past days many Instagram users reported receiving password reset emails they did not request. Security company Malwarebytes says it discovered the credentials and personal details of roughly 17.5 million Instagram accounts for sale on the dark web, and ties the disclosure to a possible API exposure originating in 2024. Engadget relays that the issue is being attributed to an Instagram API vulnerability. Instagram (Meta) responded that its systems were not breached, saying it corrected an issue that allowed an external party to trigger password reset emails for some accounts, and that users' accounts remain secure. The company told users they can ignore those unsolicited reset messages. Observers note a distinction between an API misuse or exposure and a traditional system breach, but advise heightened caution because exposed usernames and contact details could be used in follow-up phishing attempts.
Why it matters
- Personal contact and account details for millions were allegedly exposed and appear on the dark web, increasing risk of fraud and targeted scams.
- Unsolicited password-reset emails can create confusion and provide an attack vector for phishing campaigns that leverage known user data.
- Disagreement over whether this counts as a breach highlights how API misuse and data exposures are classified and disclosed.
- Even if account credentials were not directly accessed via Instagram systems, leaked profile details still enable social engineering.
