ASOS App Push Alert Used to Extort Customers

About DFIR · Medium sophistication
Last updated October 9, 2026

Attackers abused ASOS’s own mobile app messaging to send customers a threatening push notification claiming ASOS’s Snowflake environment was compromised and demanding engagement to avoid a data leak. ASOS confirmed the notification was unauthorized and warned customers to watch for follow-on phishing after potential exposure of names and contact details.

Key findings

  • Attackers sent a push notification to customers through ASOS’s own app, making the message appear more trustworthy than a normal email/SMS scam.
  • The message claimed a full compromise of ASOS’s Snowflake instance and threatened to leak data unless ASOS engaged with the attackers.
  • ASOS restricted access to its messaging platforms after confirming the notification was unauthorized.
  • ASOS said names and contact details may have been accessed, and advised customers to watch for follow-on phishing.

Who’s being targeted

  • Commonly targeted roles: Customer Support, Marketing/CRM, Security/Incident Response, Retail/eCommerce leadership, All employees (general awareness for follow-on phishing).
  • Affected industries: Retail / e-commerce, Financial services (mentioned in other nugget), Critical infrastructure (mentioned in other nugget), Education (mentioned in other nugget).
  • Attack channels: website.
  • Impersonated: ASOS / “hackers” speaking as a data-leak extortion group.

Awareness takeaways

  • Treat alarming ‘breach’ or ‘data leak’ messages, especially those demanding urgent engagement, as potential social engineering, even if they arrive through a trusted-looking channel like an official app notification.
  • Expect follow-on phishing after contact details are exposed; remind users to verify any ‘ASOS support’ outreach via official channels before clicking links or sharing information.
  • Limit and tightly monitor access to customer messaging platforms (push/email/SMS), because compromise of these systems can quickly create credible mass social-engineering reach.

Red flags to watch for

  • Unexpected high-pressure message threatening a data leak unless you respond
  • Security/breach claims delivered via an unusual channel (app push) rather than official support/security channels
  • Message pushes you to ‘engage’ instead of directing you to official ASOS help pages or verified communication methods

Imagine this: you’re shopping on the ASOS app and a push pops up saying their Snowflake data is fully hacked and your info will be leaked unless they ‘engage’. That really happened. Attackers pushed a fake breach and extortion message through ASOS’s own app, claiming a full Snowflake compromise and threatening to leak data unless ASOS talked to them. Here’s the twist: ASOS said only names and contact details may have been exposed, not cards or passwords. That means the real risk is follow-on phishing that looks like ‘ASOS support’ emailing or texting you about this scare. If you get a breach or data-leak alert from any brand’s app, don’t tap it, go to their official website or help center yourself and check there instead.
