Today we look at the various means and methods to bypass latches whether they are deadlatched or not. Buy a Traveler hook here: redteamtools.com/quick-entry/... Buy a Jim tool here: www.sparrowslockpicks.com/pro...
Locksport has taught me a lot about how to better secure my home and belongings. I really enjoy picking my old padlocks with lost keys. Never really had a reason to keep the ones with lost keys but now they actually have a use. Great stress relief
Used to have an office where the nearest door only had a latch on the inside (Fire exit). Rather than walk through the middle of meetings etc to get there I used to use a similar trick using my trusty penknife.
Thank you. I was just installing a locking door knob and wanted to know what the thing was called, what it's for, and why it shouldn't go into the hole with the rest of the thing. You've answered it all!
Great tutorial - going through your videos and it's a shame you don't upload anymore. Sad to see your content was not getting the views it deserved - hopefully you may still consider coming back to make content in the future!
I think you kind of danced around it. But on a dead latched lock, push and pull the door to try and get the dead latch to drop into the strike plate mortise. You should always try this first before going to plan B.
This! Most/many properly hung exterior doors have a felt or foam weatherstrip that is malleable given sifficient persuasion. The sweet spot within which a door closes easily but tight enough that it can't be pushed past the deadlatch is VERY narrow. Also, often a door is touching at the top or the bottom stopping travel. Observe that, attempt to move the loose margin, and then give the handle a firm tug. Click, loid, repeat.
At my previous job, I was able to get into the IT department AND the server room using that method. I showed it in front of my manager, they didn't make any changes. I don't work there anymore - stupid people.
I get shit like that all the time. And in one place used to get shit from the IT department about their 'ultra secure' room- so I broke in to their office and rigged a dummy hand grenade to a trip wire behind the door. And an airhorn attached to a pneumatic office chair. That was a really 'interesting' managerial meeting I had to attend the following day.. :/
Okay. So from a security standpoint it seems all you seem to need is a properly hung door with a reinforced frame that can't be bent by the airbag, and a round handle that can't be pulled by the UDT to defeat all these options.
How often does an average person look at a door latch and notice what the latch looks like? Another attack is destructive, but easily made unnoticeable. First cut off the security latch and leave it as is, or if you have time, replace security /latch before departure, within 10 mins, maybe closer to 4-5 min with training. The equipment and parts should be able to specify and purchase before pen test. To cut off the locking latch, fold over a jigsaw blade, into a right angle on one end. Now you have a short handle to grip one end of blade. Next bend the other end of saw blade over in same direction so that you have a square "U.". Now slip the blade into door so the serrated blade's teeth are on security latch. Pul saw blade towards you while sawing off the security latch. It only takes two mins with good saw blade and gloves to protect fingers. After that you can you can"jim" the latch open with Traveler Hook, "Quick Jim".... Of course, be sure to spell out explicitly any business-impacting risks in a binding agreement.commercial
Virtually all (serious) entry door locks now use a deadbolt, which is totally immune to this simplistic attack. But if your kids are cutting up in the bathroom and won't unlock the door, you have the key!
Issue is not in the lack of deadbolt but impropper plate. Plate that is too big will not block the deadbolt to let it activate, rendering it useless. It wasn't explained here, but the main reason is retrofitting doors that used some common electronic locks (i don't know proper names), or workers using one-size-fits all plates to cut costs or avoid mistakes (wrong plate, improper alignment, etc).
Great demonstration but now try it with a 90 degree door frame, the 90 degree means: the door opens away from you the latch is faced towards you only very bendy tools can be used like the plastic card shims due to the 90 degree bend between the door frame and latch its an interior door to my bedroom, wooden frame and door. at first I thought it was mounted backwards. from the inside I can use the hook/jim tool. from the outside, you're going to curse alot.
This must be an American thing, building a door with an exposed dead latch, because I swear I've never seen this in any city in europe make such daft engineering mistakes.
