Wireless burglar alarm allows replay attacks
A news report [arstechnica.co.uk] from Ars Technica baffles the mind.
A security firm created a wireless burglar alarm. Wireless, you ask? Well, the keypad isn't wired to the other system components. The keypad just transmits its PINs wirelessly. Unencrypted. Without any replay-prevention.
Unsurprisingly, this is trivially broken. $250 / €225 gets you the setup to perform the obvious attack of recording one correct entry and then replaying that whenever you're entering.
What's most amazing about this to me is the lack of thought. A security system that utterly fails to think of the most obvious threat to it *should* be unheard of. Then again, I expect that reading the comments will make me weep for mankind.
A 'full' life in my experience is usually full only of other people's demands.
