A gun safe's purpose is obvious in its name, but many readily available models fail to deliver, as this 3-year-old safe-cracker is quick to demonstrate.
A number of consumer-grade safes already proven to be dangerously insecure are now due to be hacked apart at DefCon. One of the worst offenders includes the Amsec EST916 which has been shown to open with just a jostle or two. It's not exactly clear from the video below whether the safe is re-locked after being closed, but even so, its inability to stay shut after just a drop or two makes it bad even for a cabinet.
Of the other safes up for DefCon scrutiny none are bad enough that they can be fumbled open, but many are vulnerable to even the most crude attempts at access. One model of Stack-On bio-metric safes, for instance, can be opened simply by placing a paperclip or key-blank in the key hole. Yet another safe can be bypassed by prodding at the latch with a flattened straw.
Not all of these safes are marketed as being gun safes specifically, but they are all marketed as being, well, safe. If you were looking for yet another gun-related safety issue to worry about, this might be it. It's always good to be security-minded, but randomly picking the cheapest safe off a store shelf won't always cut it, and none of these are likely to come out of DefCon looking safer than they did on the way in.
