Any ideas? https://t.co/WZkWta5dekOctober 6, 2026ASOS customers first reported receiving the push alert above on Tuesday morning at around 4.55am ET / 9.55am BST.This coincided with a spike in reports on Downdetector. The message is addressed to ASOS' data protection officer (DPO) and IT team, but was sent to customers.The 'Snowflake' the message refers to is a Software-as-a-Service (SaaS) that organizations use as a dedicated cloud environment to store, process, and analyze data. This is what has concerned security experts, although it's a little early to say whether customer data has been compromised.October 6, 2026 – 8:25 AMWhat should you do?Did you get the ASOS 'hacked' notification? If so, there are a few important things that you shouldn't do, including clicking the Telegram link in the message. You should also:Avoid clicking links in any suspicious emailsDo not click links in any suspicious texts or messagesOther cybercriminals could try to exploit the hysteria caused by the ASOS notification, so you should be particularly wary of emails telling you your account has been compromised, or asking you to reset your password.It's also wise to be careful about shopping on ASOS until the company comments publicly on the issue, which hasn't happened yet.October 6, 2026 – 8:40 AMWe've been hearing from cybersecurity experts on the potential implications of the ASOS notification.Pieter Arntz, Senior Malware Intelligence Researcher at Malwarebytes, told TechRadar Pro, "It’s too early to say how much ASOS customer data attackers could get their hands on, but the potential scope is significant. ASOS uses Simon AI for marketing, which runs on Snowflake, making the connection indirect.""Any exposure could reveal a detailed customer picture, from browsing and buying habits to location and loyalty status. That’s valuable profiling data, though the connection alone doesn’t establish what attackers could actually access," Arntz said.October 6, 2026 – 8:54 AM“Snowflake is a massive cloud database where retailers typically store sensitive customer information, 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," said Dray Agha, senior manager of security operations at Huntress.The push notification suggests attackers have breached the systems controlling the ASOS mobile app"This is clear public extortion. Sending a ransom demand directly to consumer devices is an aggressive extortion tactic designed to force the business into a quick negotiation. I strongly advise shoppers to watch out for targeted phishing attempts while we wait for official confirmation of a data breach.”
