Ted Harrington, a San Diego-based cyber-security specialist, and author of Hackable: How To Do Application Security Right, says firms should have started by giving all home workers a dedicated work laptop. While many larger companies may well have done this, not all smaller firms necessarily have the resources to do so, but Mr Harrington stresses its importance.
However, charity shops are better prepared this time, Mr Osterley said. Take for example Stockport hospice charity, Beechwood Cancer Care. There's been a queue of customers at its Heald Green precinct. But it is only open to shoppers, not droppers, this week.
