Altering the logon password — the one used to get the set up menu via your web browser of the router – is a great first line of defence. This specific risk relies on the truth that the majority of routers are left on their default password (typically something like 1234, 0000 or Admin). This isn’t an issue for ISPs and on the rare occasion they may should access your router you just tell them the new password. Make sure you pick something that isn’t easily guessable, the longer the better and prevent common words, names and so forth. Resetting an infected router should get things back on track, but additionally, it will reset the password, thus remember to alter it again it will not be invulnerable to assault.
