Popular home security system SimpliSafe can be easily disabled by burglars
It’s not unusual to hear of vulnerabilities in smart-home security systems these days, as security researchers turn their attention to the Internet of Things. It’s worrying, though, when a modern security system turns out to be vulnerable to a so-called replay attack, the kind of thing that worked against garage door openers back in the 1990s.
The latest example is SimpliSafe, a wireless alarm system that’s marketed as cheaper and easier to install than traditional wired home security systems. Its manufacturer claims that the system is used in over 200,000 homes in the U.S.
According to Andrew Zonenberg, a researcher with security consultancy firm IOActive, attackers can easily disable SimpliSafe alarms from up to 30 meters away, using a device that costs around $250 to create a replay attack.
