Instagram Addresses Password Reset Glitch Amid Separate Data Exposure Concerns
In early January 2026, Instagram users worldwide received unsolicited password reset emails, sparking fears of a potential breach. The messages, sent from Instagram’s official security address, urged recipients to reset their passwords despite many not requesting the change. Speculation about a hack or broader security incident quickly spread, though Instagram later confirmed no accounts were compromised.
On January 11, 2026, Instagram acknowledged a technical flaw in its password reset system, which allowed an external actor to trigger legitimate reset emails for certain users without accessing accounts or breaching core infrastructure. The company stated that the issue had been resolved and that users could safely ignore the emails, though the incident caused confusion and disruption.
Separately, cybersecurity firm Malwarebytes identified a dataset containing personal information tied to 17.5 million Instagram accounts circulating on underground forums. The exposed data including usernames, email addresses, phone numbers, and partial physical addresses stemmed from an earlier 2024 API exposure, not a new intrusion. While passwords were not included, the dataset raised concerns about potential phishing, identity theft, and social engineering attacks.
Instagram’s response emphasized that no user data was stolen during the password reset incident, though the unrelated circulation of scraped information highlighted ongoing privacy risks. The episode underscored the challenges of protecting user data on large platforms, where even older exposures can resurface and be exploited. The company’s swift clarification helped distinguish the fixable glitch from a full-scale breach, though questions remained about the external actor’s methods and motives.
