$20 'Toy' Deactivates Cheap Home Alarms, Opens Doors

mask.of.sanity writes "Cheap home alarms, door opening systems and wireless mains switches can be bypassed with low-cost and home-made devices that can replicate their infrared signals. Fixed-code radio frequency systems could be attacked using a $20 'toy', or using basic DIY componentry. Quoting: 'Criminals might be able to capture IR signals if they can get a line of sight to when the system is being armed or disarmed. If a criminal knows what type of alarm system you're using then they could do what we did here and reverse it for cloning a remote. A more likely scenario is just to buy a duplicate system and use that remote. Not all IR remotes can be switched from the same system. It depends on whether a code is being transmitted and how many variations of the code and remote exist. In the system described in this post, there is no code, just a carrier signal. If a code is being transmitted, then the Infrared toy can capture it and replay it. So that's your best bet for a criminal looking at a completely unknown remote.'"

It's almost as if the security company is selling the appearance of security instead of actual security. Surely, they wouldn't be so mercenary.

If your insurance company asks if you have a security system and you say "yes" because you spent $8 on one, is that fraud?
