Comcast security flaw could help burglars break into homes undetected
A security vendor says it discovered a flaw in Comcast's home security system that could let criminals break into houses undetected by using radio jamming equipment.
Though primarily known for its cable TV and broadband Internet services, Comcast also sells Xfinity-branded home security systems.
Vendor Rapid7 found the flaw in Comcast's implementation of the ZigBee wireless protocol. Attackers armed with commodity radio-jamming equipment can "cause interference or deauthentication of the underlying ZigBee-based communications protocol," Rapid7 said. When this happens, sensors that detect motion or open doors and windows are unable to communicate with a base station hub in the home that controls the alarm system.
Comcast says industry-standard tech to blame, but will try to fix it.
