Routers from well-known manufacturers vulnerable to cross-router data leaks

While many organizations and home networks use a host and guest network on the same router hardware to increase security, a new study by Ben-Gurion University indicates that routers from well-known manufacturers are vulnerable to cross-router data leaks through a malicious attack on one of the two separated networks.

According to Adar Ovadya, a master’s student in BGU’s Department of Software and Information Systems Engineering, “all of the routers we surveyed regardless of brand or price point were vulnerable to at least some cross-network communication once we used specially crafted network packets. A hardware-based solution seems to be the safest approach to guaranteeing isolation between secure and non-secure network devices.”
