Comcast s Xfinity Home Security System is vulnerable to attacks that interfere with its ability to detect and alert to home intrusions. The problem occurs when an attacker is able to jam the 2.4 GHz radio frequency band used by window and door sensors to communicate with the system’s base station. The base station does not record, nor does it alert homeowners to the interruption, Rapid7 says. Comcast says it is reviewing the research and will proactively work with other industry partners to identify possible solutions.
