The UK’s leading cyber security agency has advised retailers to take action to protect themselves as Marks & Spencer continues to suffer disruption following an attack.

The recommendation came from the National Cyber Security Centre (NCSC) , the government-backed body that focuses on developing cyber security capabilities and responds to incidents, the BBC reported.

The NCSC has urged retailers to stay vigilant, and review and upgrade their procedures.

Business at Marks & Spencer has been interrupted following an attack almost a fortnight ago, which hit contactless payments and click-and-collect avalability. The retailer has since suspended trading through its website and apps, and availability of some food items has been affected in some stores. The Metroplitan Police has been called in, and M&S is also working with the National Crime Agency and NCSC. 

Food retailer the Co-op yesterday became the latest retailer to be targeted by cyber criminals, prompting it to take measures to fend off the attack which it said had a “small impact” on its call centre and back office.  

Marks & Spencer has not issued any new information about the cyber attack in the last few days, such as when the problems may be resolved and online trading might resume. However, the retailer has previously said that there is no need at present for customers to take any action in response to the incident.
