In an article from the New York Times, the FBI has urged everyone with an internet router to turn it off and then back on. A malware system linked to Russia has already infected thousand of internet routers.
Th FBI has a few recommendations for any owner of a small office or home office router. The simplest thing to do is reboot the device, which will temporarily disrupt the malware if it is present. Users are also advised to upgrade the device’s firmware and to select a new secure password.
Here is a statement from the FBI:
