Asos Hack Notification Sparks Data Breach Investigation 2026

Asos, the online fashion retailer, is investigating a potential data breach after users of its mobile app received a push notification claiming hackers had 'fully compromised' its data. The notification, titled 'Asos hacked', included a link to a Telegram messaging service and caused Asos shares on the London Stock Exchange to dive almost 12%.

Asos Hack Notification: What Happened?

On Tuesday morning, thousands of Asos customers received a push notification from the Asos app that read: 'Dear Asos DPO and IT, we have fully compromised the Snowflake instance.' The message directed users to a Telegram channel, suggesting a coordinated extortion attempt. Despite the notification, the Asos website and app appeared to be operating normally, and it is understood that Asos is still investigating whether any actual hack has taken place.

Understanding the Snowflake Connection

Snowflake is a cloud platform used by many retailers to store, process, and analyze data, including transactions and demographic information such as clothing sizes and body measurements. It also enables push notifications to clients' phones. Dray Agha, senior manager of security operations at Huntress, an online security firm, commented: 'Snowflake is a massive cloud database where retailers typically store sensitive customer information – it is a real worry if cyber criminals have indeed accessed it as they claim. The push notification suggests attackers have breached the systems controlling the Asos mobile app also. This is clear public extortion.'

Potential Impact on Asos and Its Customers

If the breach is confirmed, Asos customers could face risks related to their personal data, including names, addresses, and purchase histories. The financial implications for Asos are already evident, with shares plummeting nearly 12% following the notification. The company has not yet released an official statement regarding the validity of the hack.
