Bypassing locked doors?

Aydun · 10 Jul 2015, 10:41 pm

Obviously we don't condone this sort of thing..

But it's practically impossible without physical access to a card.

Assuming an RFID tag has a 32bit key, that's 2^32 or 4,294,967,296 possible combinations. Authentication usually takes a couple of seconds, so it'd take 100s of years to try every possible combination.

Abandoned places never have electronic locks.

There are places that are temporarily abandoned, though, that require access codes or electronic modes of access. I know of at least one. Fully abandoned places don't though, you are correct on that note.

Learn about RFID. It's doable.
125Khz is generally easypeasy to clone, I've got about 50 people sharing a Gym membership.

13.56Mhz is also getting easier, if you look into the hacking community you can learn a lot, conferences like AUScert and Ruxcon generally have a few talks a year on this. I can go in depth, I've given talks on it myself, but I don't really know if this should be in the general forum, maybe on VIP before we discuss it more? There's a ridiculous amount of insecurity built into alarm/access control systems, to the point where with some oldschool Freaking techniques, you can remotely open doors with nothing but a dialup modem.

As for Bump Keys, you need the right key profile for that bump key, almost all buildings use at least a restricted keying platform, if not something like BiLock, Kaba, Twin, MT5, Medico, Protec etc, and picking in the field is very different to the YouTube videos teaching you how to do it, tight keyways, a lot of distractions and difficult workspace make it a lot harder.

@CafeCSK, I live in the same city as you, and 99% of buildings don't have RFID on the roof doors. Only on entering the elevators etc, which are easily bypassed by just sidesurfing or going in via the carpark. Never had an issue getting to the stairs. As for brute force in rooftops, I can't think of a single building I've had to resort to that on, and I've done the 10 tallest.

But I like rooftops :'(

There's plenty of nice rooftops accessible without having to bypass hi-tech security. And hi-tech security is almost always accompanied by CCTV and regular patrols.

And if you can beat electronic locks you are in the wrong hobby.

Cloning's one thing. Creating a card from a reader? Not possible. All a basic reader needs to do is need to emit an inductive field to power the card. Just electromagnetic energy, no data.

if you cant coathanger the door don't worry about the door.

Are rooftops that important in your life?
If so, just pay the $30 and go up Centerpoint Tower, you get a sick view of Sydney from up there.

I seriously don't know what this thread is trying to achieve.

Fair enough, if you like a challenge you should join the army.

But TBH, you're trying to put in way too much effort for not much gain.

If you wanna learn how to beat those locks, take a locksmiths course.

Cards and rfid are all things that can be duplicated in one fashion or another.
They were created in the first place - with time and effort one way or another they can be reproduced.

But the question is - What are you going to gain from it?
Say you duplicate a card perfectly, say for argument sake you even had someones card..
Your entry is STILL going to be logged and visible. And as others have said - recorded on camera at minimum.

Any good security system is going to compare your entry and usage against work rosters, maintenance schedules, etc, and alert pretty quickly an entry into an area that is highly restricted at the best of times.
It is only a poor security system that will simply replace a traditional key for an electronic one.
Reality is that the migration to electronic and digital is far more than just an alternative way to lock or unlock doors.

Going down your path - is this worth the alarm bells that might be triggered?

I dont skin cats - but i hear there are many ways to do so.

hey guys, i havent had much experience with electronic locks, cameras and sensors yep lol.
on other locks, i like yo remove a link of chain (brute force/bolt cutters/battery grinder/oxy/saw) and replace the lock with an abus lock with the local councils id engraved on it.. no one questions it anf you have your own key
cheers

Tell me about your Oxy cutting skills..... this should be worth a laugh

You've got to admit he's got skills;
First off he can brute force a chain off a lock. The man must have muscles like no other, I'm envisioning the hulk.
He's able to conceal a pair of bolt cutters big enough to cut a decent chain, making him gargantuanly tall to hide them in his trousers, I'm picturing Mr Tall from the Mr. Men Series.
He's got super stealth for being able to use a cordless angle grinder silently, and without setting off smoke alarms
He's got the ability to walk past reception/concierge and climb 40 flights of stairs with 2 individual bottles of gas, PPE and mixing gear.

All of this and he's "bypassing" the locked doors, silly me, thinking bypass was all about being stealthy and unnoticeable.

tommo · 16 Jul 2015, 6:08 pm

i must have been mistaken, i wan not refering to electronic locks. i was refering to other methods, i prefer abandoned buildings and mines. these locations often allow for some noise. cordless grinders often go unnoticed with only a 20second run time with a 1mm disc if its a remote location and c sized (colt) bottles are bulky but very effective. youll be amazed how resting one arm of 36" bolt cutters against the ground or rock as in a mine you can cut rated chain using your shoulder. as for brute force, a 500mm piece of 4140 bar with the end turned down like a podgy bar will pop most padlocks and or snap welds if the chain has been welded (as most inexperienced welders will find no preheating the chain weakens it)
maybe ask a few questions before s*** canning others

tommo · 16 Jul 2015, 6:54 pm

also another technique on modern facilities, most have just reed switch type sensors on doors making lock picking useless unless you can bypass security, in some locations where there isnt any cctv, you can drill out the louvered panels on doors that have the filter elements in them (cant undo as they normally are constructed with nyloc nuts on the inside, so you simply drill the bolts out, remove the panel (clean swarf that lands on outside, rarely falls inside) then drill out the inner panel to suit nutserts, screw in nutserts and you can replace the screen with original sized bolts, most maint crews would never notice the change as it looks professional anyway. gaining access and bypassing door reed switches. just a thing to think about. depends how keen you are on getting into places un noticed.h yeah i weigh 120kg of ballast or fat what ever you call it, either way its a lot of leverage lol
