Recent cyberattacks have targeted major UK retailers, prompting a call for increased vigilance and stronger defenses from the National Cyber Security Centre (NCSC). High-profile organizations such as Harrods, Marks & Spencer (M&S), and Co-op have been affected, causing significant operational disruptions. These attacks have led to restricted internet access, pauses in online order processing, and in some instances, potential data extraction, highlighting the severity and broad impact of these cyber incidents on the retail sector.
The NCSC has issued an urgent warning to UK firms, emphasizing the escalating risk of ransomware attacks, particularly within the retail industry. The agency anticipates a potential increase in similar attacks in the coming days. In response, the NCSC has released a comprehensive set of guidelines designed to assist businesses in bolstering their defenses against these threats and minimizing potential financial losses. This includes reviewing password reset policies, being cautious of senior employees with escalated priviledges such as Domain Admin, Enterprise Admin and Cloud Admin accounts.
The NCSC's guidelines emphasize proactive measures such as isolating and containing threats quickly by severing internet connectivity to prevent malware spread and ensuring backup servers remain unaffected. It also highlights leveraging backup systems for recovery and implementing multi-factor authentication (MFA) across the board. The NCSC advises businesses to constantly be on the look out for ‘risky logins’ within Microsoft Entra ID Protection, where sign-in attempts are flagged as potentially compromised due to suspicious activity or unusual behaviour. Furthermore, the agency urges organizations to assess their cyber resilience and adopt best practices for both prevention and recovery to mitigate future attacks.
