Researchers have discovered that malware dubbed VPNFilter affects many more brands of routers than first thought, adding six more names to the list they enumerated on 23 May. They have also found that it can deliver exploits to endpoints.

A respected American security researcher says the FBI's advice, to reboot all routers in order to supposedly get rid of malware called VPNFilter, is "best described as moronic".

The FBI has used a court order to gain control of a domain that served as an emergency back-up for a piece of malware known as VPNFilter, making it possible for infected network devices to now reboot and avoid loading the second and third stage of the malware.
