One recent facility security assessment started with the question below, and after encountering this vulnerability in every assessment for the past 15 years, it became obvious that it was time to write about it. The problem is easily remedied.
Q: We installed a good quality lock industrial, yet someone was able to bypass it using a credit card. How could this be?
A: Most likely the door latch installation somehow kept the deadlocking plunger (also called a deadlock latch) from being engaged, or allowed it to be disengaged. It is the purpose of this part of the door lock mechanism to prevent doors from being opened in this fashion.
Over the past 15 years, when I started tracking this particular vulnerability in our facility security assessments, in every commercial facility security assessment I performed, I found that at least one door could be easily opened (5 seconds or less) with a credit card, screwdriver or hair comb.
Facility managers have been amazed to see strong commercial and industrial locks bypassed this way. Recently at one facility, after a big name company installed card + pin electronic access control (card reader plus keypad) for a half-dozen very critical internal doors, I was able to slip my comb out of my pocket and pop open each door. IT departments take note: this vulnerability is common for IT equipment room closets, especially where the closet originally served another purpose, and was later given to IT without upgrading the door to a security grade installation.
Here are photographs from a Time-to-Target assessment in which we easily defeated a number of doors using a small screwdriver. What's worse, we discovered that when the door shown below was forced open, it did not alarm.
Oh that's such a rabbit hole to go down into.
Deviant Ollam has a few great presentations about his work of getting into secure areas, e.g. https://www.youtube.com/watch?v=rnmcRTnTNC8
You'll never trust a door again ;)
it's a shame he's such a faggot
Is this spam, or are some of us going crazym
Can't you get into pretty much any secure building if you show up with a hardhat and a clipboard?
Nah, you just need the clipboard. Maybe wear a jumpsuit with a patch on it.
Not sure how this topic belongs here, but this shouldn't matter much for the average homeowner anyway. If someone is breaking in through your front door, they're probably using a bump key. But it's much more likely they get in through a sliding door or a basement/first floor window. The lesson is to have layers of security beyond relying on a single lock.
Also, how to align the plunger is covered in the instructions of even the cheapest doorknobs at Home Depot. If you've ever replaced a doorknob (you should have when you moved into your home), you've already checked for this. Your front door also probably has a deadbolt anyway.
Also here is what a Deadbolt Plunger is and how it is suppose to make your deadbolt latch click into place: https://www.youtube.com/watch?v=ShWybszO4ik Shows both correctly and incorrectly installed where the latch doesn't actually connect even if it appears locked.
What kind of retards depends on the default locking mechanism on a door handle for security. Get an actual fucking deadbolt mechanism and install it in addition to the mechanism attached to the door handle or knob. You can't slip a credit card into a deadbolt mechanism because it's usually an inch into the frame when it's locked and it doesn't have a gradient to it that'll allow you to slip a screwdriver or a card into the gap to defeat it.
I haven't seen a house without deadbolts in at least 20 years.
Mods really gotta do something about the spammers.
