The recent ransomware attacks on M&S and other British retailers serve as a reminder – as if we needed one – of the ubiquitous nature of cyber crime, and the widespread disruption which it can cause to both businesses and individuals.

The BBC has reported that M&S began experiencing problems over the Easter weekend (the risk of cyber attack increases during public holidays) and that some of its operations, including online food ordering, remain offline some two weeks later.

The UK’s data regulator, the Information Commissioner’s Office, has confirmed that it is “making enquiries” with M&S, as well as the Co-op Group, which was also subject to recent attack. The ICO will be looking to establish whether the security measures employed by M&S and the Co-op were appropriate, or whether they contributed to the success of the attacks. If either entity is held to have breached its obligations under the UK GDPR, formal enforcement action may follow. 

Following these incidents, the National Cyber Security Centre has published further recommendations for businesses on the steps they can take to improve their security position.

In addition to the impact on the companies targeted by the attack, individuals may also be affected where their personal data was exfiltrated by the attackers. As well as the loss of privacy, this can expose individuals to increased risk of identity theft or fraud.
