Home routers largely unpatched, raising risk during Covid-19 WFH

Employers who have suddenly shifted a large percentage of their workforce to remote due to Covid-19 no doubt will shudder by the findings of a new Fraunhofer Institute for Communication, Information Processing and Ergonomics study that concluded no home router was without security vulnerabilities.
