    Ah, so now anyone wanting to set off the motion detectors had to slip something above or below the doors?

    For the doors with PIR sensors you can use a can of air duster (the ones with with the little tube) to create a cloud of cold air on the other side of the door. Most PIR sensors will trigger on that.

    Hopefully they kept the Jefferies' tubes opened.

    For anyone else who was confused by this, I think the point is that by slipping the yardstick between the doors, he triggered the motion detector on the far side.

  • (nodebb) in reply to jkshapiro

    That was how I read it, too.

    Sometimes works with an e-cigarette or a compressed air can down side up to trigger the motion sensor... There is a great talk about related topics: "I'll Let Myself In: Tactics of Physical Pen Testers": https://www.youtube.com/watch?v=rnmcRTnTNC8&t=2405s

    Many organizations would have "solved" this problem far more cheaply: by firing GRG.

    Sounds like he did it in front of a bunch of his colleagues. They'd have had to fire everyone in the room. And, even then, this guy figured it out while he was drunk. You have to have your head pretty far up your butt not to realize that someone who's sober will figure it out more eazily.

    I worked in an office with one of those electro-magnetic door locks. I discovered by accident that it could be opened just by shaking the door (not very hard), though it was resistant to a straight push. I'd like to think that was a one-off sample fault though the nature of it screams "design flaw"

    Yeah, this is a common bypass entry method.

    Deviant Ollam showed it in a talk on bypassing entry doors this way. Here's the direct link https://www.youtube.com/watch?v=S9BxH8N9dqc&t=1071s

    Air dusters, cold sprays, or just vaping can do it.

    Our building entry doors are like that. The office entry door isn't - there's a physical latch you twist which disengages it form the electronic latch. So swiping your badge unlocks the electronic latch letting you in, to let yourself out you turn the doorknob which pulls the door latch in and lets you out. This way even if power fails, you can still exit the office, but not so sure about the main door...

    And for people who are confused by an entirely different aspect of this, a "yardstick" is a type of ruler around 1m long.

    Seen that. We had some doors that required an ID card to open, with a reader on each side, because it was a security door between two separate parts of the org. and not everyone should be able to use it.

    For fire escape purposes, the architect had specified "break glass to exit" panels on the inside of every secure door.

    Both sides of this door were "inside" for their part of the org., and this secure door could be opened by anyone with a screwdriver to open the break glass switch.

  • WTFGuy (unregistered)

    In many cases, the "break glass" switch also triggers the fire or emergency alarms in that area. So your surreptitious attempt to enter some forbidden zone might well bring on more scrutiny than you were expecting.

    This might not have been true in your particular building, but tis true in many.

    The thing I'm learning about people employing security systems of any kind is that they can often assume people play fair or only play by the rules the security people are setting up. Years back I was working a project with a friend when a security hole occurred to me. My friend implemented the part that I was concerned about. I told him on a Friday. He told me, "I'll take a look at it on Monday. Nobody's going to think of doing what you said." I replied "I thought of it!" He shrugged it off. Come Monday and someone exploited the hole over the weekend, and we lost a few thousand dollars. He said, "OK, OK, you can tell me you told me so." Personally, I don't like having to do secure setups, not because doing decent work concerns me, but because I end up feeling so dirty trying to think through crooked ideas.

    " and an access panel that could be shot with a phaser to permanently seal or, depending on the plot, automatically open the door. " this remind me of a line in "peter's evil overlord list": "My door mechanisms will be designed so that blasting the control panel on the outside seals the door and blasting the control panel on the inside opens the door, not vice versa."

The ordering process Doors Los Angeles was straightforward, and they provided detailed information about each door, including measurements and specifications.
