The hackers, identifying themselves as the “Xuanye Group,” asserted via their Telegram channel that payment information remained secure and that the app itself was safe to use.

Chief technology officer Marijus Briedis warned that criminals often exploit such publicity to impersonate retailers, sending emails or texts designed to steal credentials or financial information by prompting users to reset passwords or confirm account details.

This incident adds to a series of cyber challenges facing the British retail sector, following similar security events last year involving firms such as Marks & Spencer, the Co-op, and Harrods. In some of those cases, companies faced temporary stock shortages or were required to temporarily shutter websites to sanitize their internal systems. M&S and the Co-op experienced stock shortages and the former was forced to close its website for several weeks as it battled to ensure its systems were clean.
