ASOS app users in Australia and elsewhere received a disturbing push notification on 6 October 2026, in what is being treated as a hack of the online fashion retailer. The message contained a data breach warning and threatened to leak customer data.

Users reacted with alarm on social media, with outlets including News.com.au, Nine.com.au, the BBC, and the ABC reporting growing anxiety among customers. ASOS has yet to confirm the extent of the breach or how many customers are caught up in the incident.
