ASOS Plc

Snowflake shares fell about 3% in premarket trading on Tuesday after ASOS customers received a notification claiming that hackers had compromised the retailer's Snowflake instance and threatened to leak data. The notification, addressed to ASOS's data protection officer and IT department, was widely shared on social media and reported by media outlets. "Dear ASOS DPO and IT, we have fully compromised the Snowflake instance. Engage with us, or we will leak it," the message reads. The reports also weighed on ASOS shares, which fell more than 10% in London. Snowflake did not immediately respond to Seeking Alpha's request for a comment.

Asos customers have been sent a phone alert claiming the online retailer has been hacked and warning that their personal information has been compromised. The app push notification, titled "Asos hacked", read: "Dear ASOS DPO and IT, we have full compromised the Snowflake instance. Engage with us, or we will leak it." The message, which directed recipients to a Telegram account, appeared to be addressed to the company's technical staff. Shares in Asos tumbled by nearly 13pc on Tuesday in the wake of the reports. Snowflake is a cloud computing company that provides data hosting and processing services, and an instance refers to a company's individual system, which may host customer data such as sizes, browsing and purchase history, home addresses and phone numbers. The extent of the data available is not clear, and Asos was contacted for comment. A raft of UK retailers have been targeted by cyber attackers over the past two years, including Marks & Spencer and Harrods.
