The point being that an alarm or other RF device ceases to work. I've seen it caused by baby monitors from China that don't obey the duty cycle rules, a malfunctioning weather station, horrific spurs from a wireless video transmitter.

Really? I've looked into several cases of unintentional jamming caused by malfunctioning devices.

I don't disagree with that, I've seen enough issues with various devices unintentionally jamming 434MHz and 868MHz. What I don't understand - and I have tested with two alarms bought 4 years apart, and one installed alarm - is that I cannot set the Yale jamming detection off. Even 0.5W of...

It's not in his threat model of "14 year old smack head with an old screwdriver".

It can be made significantly harder though, to the extent that it's not possible with reasonably priced equipment. Two-way RF makes a huge difference. Instead of an absence of signal, you look for an absence of response. You can poll the detectors much more frequently when the system is armed...

Also still can't work out why the Ubuntu desktop is relevant.

I mean, where is your line for a vulnerability being serious? Encryption totally token? http://cybergibbons.com/alarms-2/multiple-serious-vulnerabilities-in-rsi-videofieds-alarm-protocol/ Backdoor root account...

Paul - what are you talking about? I'm trying to work out how I could have written the blog yet not understood any of it. That's nonsensical. I know I link to the paper. It's the source of the image, that's it. I'm wondering what the relevance is of the rest of it's content (which you brought...

Just link the tampers out in the panel.

Oh, when I published the Heatmiser issues, I got more than a few reports of people who had previously had their heating altered randomly.

Haha, yes. I think I might get the blame though :)

Yes, the wider implication is that these problems can be avoided, at little additional cost. Connect something to the Internet and you don't just need to worry about a burglar.

A surprising number of burglaries happen with the occupier present. Cash and jewellery are still the biggest by value taken during burglaries.

Stealing high-end cars requires a lot of time and effort to get them sold on, unlike cash, jewellery, and phones. The person doing the crime doesn't see a fraction of the value. Prison terms for non-aggravated first offence are similar for both.

I'm just wondering why jamming is being seen in car theft, but not burglary. Both aren't exactly risk free, and the reward to the guy actually doing the crime is about the same.

Why the difference between car thieves and burglars then?

Wouldn't average joe be better securing his house before spending money on an alarm?

I'm not sure of the relevance of the paper here? The physical keypad locks you out, the RF doesn't. I'm puzzled. Why wouldn't a burglar spend £50 on a jammer that means that the alarm won't go off? They don't need to make or program anything...

If it's the same one I have just posted about, what surprises me is that we can't get the jamming detection to trigger with intentional jamming, yet loads of people have issues in the real world.

I've alluded to these issues before, but after doing a seminar at IFSEC last week that was fairly well received, we've published a blog about the issues with wireless alarms, and their Internet connected brothers...
