Serious security failings in home routers are getting more attention from both attackers and researchers.
In recent weeks, attacks have been mounted on Linksys and Asus routers via loopholes that thieves could exploit. In Poland, reports suggest one gang has successfully adjusted router settings in a bid to steal cash.
A separate study found many of the routers sold online have bugs that attackers could easily exploit.
This week the Internet Storm Center (ISC) warned about a continuing attempt to exploit a vulnerability in 23 separate models of Linksys routers.
The virus, a self-replicating program or worm called The Moon, takes control of the router and then uses it to scan for other vulnerable systems.
