The Defeat of High Security Contacts


Saw this while on YT today, seems a bit concerning seeing these used on the outside of safes and vaults everywhere. I know there is a PDF from a few years back that went into detail about the construction and vulnerabilities of these, but I cannot seem to find it. Looks like the new magansphere contacts are reasonably priced too.

Re: The Defeat of High Security Contacts

Thanks for sharing! Just goes to show that no security system is 100%. It takes a fair amount of time and inside knowledge to bypass something like this, not to mention the motion detection and high security locks that should be used in conjunction. Imagine trying to bypass that thing from the other side of the door.

You'll note how he carefully placed the 'defeat sleeve', and how the device went into alarm when the magnet housing came close. When defeating reed switches, one must be careful not to orient the magnet backwards and disrupt the magnetic field holding the switch closed. i.e. in real life this requires access to the reed housing, knowledge of the orientation of the magnets and a little luck.

Re: The Defeat of High Security Contacts

Cool defeat but it has been around for 30 years. There are other ways to trick them too.

If you are at an unknown door, you can scan the edge of the frame for this type of sensor. If it is just a reed switch then it is fairly easy to overcome, all you have to do is copy what the magnet is doing. It matters not if it is a NO or NC, just copy the magnet. If it is a balanced 3 reed switch (with tamper) then you will need a little extra info on the sensor. Again, the quickest way would be to scan it while unalarmed, or even maybe through the outside of the door (like with the single reed switches). Replicating polarity and field strength are the keys.

I would be surprised if all of the 3 switch balanced sensors from a particular manufacturer were configured the same. So his defeat stick would only work on an unklnown sensor if that were the case.

Re: The Defeat of High Security Contacts

Needs a Hall effect sensor probe and an electromagnet. You'll find the magnet and sensor easily from the outside of the door, then can come up with a plan.

The higher end sensors also use a Hall effect sensor and trigger if the feild changes rapidly, so sticking another magnet to it would likely trigger it anyway.
