Online fashion retailer Asos has officially warned its customer base regarding a significant data breach. The company confirmed that unauthorized individuals have gained access to sensitive personal information, including customer names, physical addresses, phone numbers, email addresses, and unique customer identification numbers.

The breach came to light after hackers contacted the BBC, prompting the news organization to reach out to the retailer for comment. Asos has since acknowledged the incident and is in the process of notifying those whose data may have been compromised. While the company has not provided a specific timeline for when the breach occurred or how many users were impacted, they have confirmed the scope of the information exposed.

Security experts generally advise customers of affected platforms to remain vigilant against potential phishing attempts, as the stolen contact information could be used by malicious actors to impersonate the company or other services. Asos has not yet released details regarding the specific method used by the hackers to bypass their security systems, nor have they stated whether financial information, such as credit card numbers, was included in the stolen data set. The company is currently working with relevant authorities to investigate the extent of the unauthorized access.
