UPDATE: VPNFilter is now known to infect more routers than first expected and has increased capabilities such as performing Man-in-the-Middle attacks that can intercept usernames and passwords. Even https:// traffic is affected as the malware can downgrade the encryption from https:// to http://. In addition the malware can also infect the computers in the network that the infected router resides. This is a very nasty malware and if you had checked the list and found your router was not on the list, you may want to check again as the list has been updated to reflect more router manufacturers and models of existing router manufacturers.
