The FBI has disrupted a network of half a million routers compromised by the group of Russian hackers believed to have penetrated the DNC and the Hillary Clinton campaign during the 2016 elections, according to reports. The hacker group, known as "Fancy Bear," has been using a malware program called "VPN Filter" to compromise home and small office routers and NAS devices. VPN Filter is "particularly concerning" because components of the malware can be used for the theft of website credentials and to target industrial system protocols.
