The National Cyber Security Centre (NCSC) has urged organizations to enhance their security measures following cyber attacks on major UK retailers such as M&S, Co-op, and Harrods. Specifically, the NCSC emphasized the importance of reviewing password reset procedures and authenticating requests from users, particularly for accounts with elevated privileges. It recommended implementing multi-factor authentication (MFA) and monitoring for 'risky logins' in Microsoft Entra ID Protection. The attacks have significantly impacted M&S operations, highlighting the critical need for proactive measures to prevent and respond to security breaches.
