UK retailer Co-op shuts down some IT systems after hack attempt

British supermarket chain Co-op temporarily took parts of its IT systems offline after detecting attempts to gain unauthorized access, causing limited disruption to back-office and call-center services while stores and customer-facing operations remained largely unaffected; no confirmation of a successful breach or claims by threat actors has been disclosed. The report places this event in the context of recent UK retail attacks, notably a Marks & Spencer incident attributed to the Scattered Spider group using DragonForce ransomware.
