RFID reader technology and cloning tags!

[@Reman1975]

When you mentioned the wear marks on keypads it reminded me of a manager I had years back. He took offence to us night shift scum going in his nice warm office and using his lovely high end PC to generate stock control labels rather than using the temperamental old PC in our unheated portacabin in the yard. We'd been using his PC for months before he noticed, But as soon as he did he got very snotty about it. He had one of those mechanical code locks fitted to his door, So that night I drew along the underside of all the buttons with a whiteboard marker. Next evening I went back and saw the 4 buttons that had scuffs in the pen marks from being pushed in and guessed the code on the second attempt. I also found that he'd added a password to his PC........ Which was the same as the door code. :) About a month later he confronted me and asked if we'd been in his office again (He was the kind of pedantic tit who'd leave a pen in exactly the same place on his keyboard every night to see if anyone had snuck in and used his precious COMPANY OWNED computer), Not wanting to flat out lie to management (On the off chance I'd left anything incriminating in his office the previous night), I said "Duh, Didn't you have a lock fitted to your door". He seemed quite happy with the answer and went away. He never mentioned it again, But on my last night working there I did sneak in, set high scores on minesweeper and solitaire, And put my own name against them. I hope he eventually noticed. :)

such a fake story as you say it took you two atempts to get the order of the numbers, if you knew anything about those locks you would know the order of the numbers is not relevent if the code is set as 1234 it will also work with 2341 or any other combination so you wont need two atempts

Our secure Psych. Unit uses that technology. The lock reader is activated by the proximity of my RFID ID card, and I then confirm my ID with an 8-digit PIN code. Owing to the nature of my job, security is VERY tight, which means having to memorise a new random 8-digit code every Monday. It's not just to keep our Customers "inside", it is also to protect them from their "acquaintances" outside . . . . . . . .

[@phils4634]

Chaplain Dave Sparks Never a truer phrase said, Mate! The "clients" I deal with are pretty nasty individuals - and they are all very smart indeed, which is why the system is designed the way it is. Video security links are by multipath fibre to separate buildings, we use genuine, dummy and covert camera systems, and there is no way that Inmates can view any of the entry keypads. We only enter Patient Areas in groups of three (two of whom are armed as well as very able where self-defence is concerned), and we are monitored "one on one" via the camera suite whilst we are "inside". Since the nature of our "Clients" is such that none of them are likely to be ever released into the general population, we HAVE to assume they will do whatever they think will produce the desired result for them (i.e. escape - irrespective of the consequences to others), so the system operates accordingly. I have no doubt whatsoever that, should one of my "Clients" decide that murdering me would provide a means of escape, they would do so with zero hesitation. This certainly concentrates the mind . . . .

[@bjtaudio]

The stand alone keypads are vulnerable to numerous attacks:- Copying the tags as you demonstrated, also its very easy to rip the plastic keypad off the wall to access the wires to the lock solenoid and bypass the keypad relay contacts too. Its also easy to unscrew the lid and hold down the tamper switch while bridging the contacts. Another trick is to use a stun gun on the keypad as it typically will cause the electronic and transistor driving the relay to go short and power and operate the lock too, this will destroy the keypad electronics however.

[@Larsi1997]

or just hold a big Neodynium Magnet in front of it to switch the relay then you have an open door and no Harm or traces done a very old lock would be probably more secure than this

BTW re. the resin encased unit it's worth Goggling wiegand replay attack, if you can access the wiring (e.g. by prising it off) then you can stick a simple dongle in the line that will record any cards presented to the reader, then the attacker comes along with their special card which tells the dongle to use a stored card code to open the door. I designed a custom in house system for the company I work for that uses an encrypted challenge/response link between the reader and the controller so a man in the middle dongle attack won't work. wiegand is a very weak protocol security wise yet still widely used.

[@brendondrew1691]

I am a security systems technician and this is interesting. In terms of being able to short a power supply to open a lock, any good security tech will use 2 power supplies, one for the readers and one for the locks, using transistor switch relays to open the lock. These switches are kept low with a pull down resistor when the microcontroler initialises to prevent the relays from switching during starting.

Interesting about cloning the tags like that!

@18:58 looks like the little CMOS chip is used to pump current into the coil which is controlled by the Nuvoton MCU on the other side of the PCB. The MCU and the CMOS are both acting like an RFID reader, with all intelligence coded in the same MCU. The 4069 Inverter CMOS can output up to 25 mA with DS voltage near 15 VDC and up to 5 mA with DS voltage near 5 VDC - both can be sink or source currents. Not a bad current driver into the coil antenna when using the 12 VDC Switch Mode Power supply you mentioned later.

[@rudyvk]

I actually use one of these units on my garage door.. I would never use it on my house door as I think it is easily hacked by just brute forcing the code. As I'm not using the keypad and just the RFID function, I bought an RFID antenna from eBay, desoldered the antenna wires from the board and connected the external antenna. This antenna is outside my garage. It also gives a lot better response from the unit. The antenna I used is this one: "External extend sencondary antenna for RFID access controller 125k 1.5m length"

[@SianaGearz]

It would take a few hours of typing to brute force a random enough code. This counts as secure, as there are people who will pick even high security pin tumbler locks in 20 minutes, and most of the ones people use are raked or picked in under a minute with a very moderate level of skill.

[@richbooth8948]

BigCliveDotCom is spot on about not being secure. One would be very surprised (or not) at how many are out there with this flaw. The eBay special he explains would (make that should) never be used where real security is needed or where multiple tags are issued, or where you want to know who comes in and when. Apparently, if you lose a tag, you can't remove it unless you wipe and reprogram all tags. The better ones just power a reader like Clive showed. The reader sends the chip's unique code to the micro which determines if the card has granted access at that time. Removing the reader does little towards granting unauthorized access. The better ones also have a facility code in the chip which can't be cloned (easily). As for the casino chips, they can also count what you have, track the tables you play at and movement in the casino. Access cards don't store data, access codes, account balances or eye color. They are just electronic "keys" that identify which user's information is to be accessed in a central database.

[@extrastuff9463]

+Kieron Quinn Well they are convenient and one has to keep in mind that keys can be copied as well, in some cases even when all you have is a good picture of them. And ofcourse physical locks can be picked by people that are good enough at it, having seen some videos around on youtube about the community that I hope mostly does it as a challenge it seems like there's few locks that aren't impossible to deal with. But locks whether they are the electronical kind of old fashioned physical kind will never be a foolproof thing, at best they make it inconvenient or slow competent thieves down and make the less competent ones resort to brute force entries that hopefully set off the alarms or get noticed. And as for what your Uni uses, they may well use something that functions similar to NFC internally but operates on a different frequency or uses a different standard on the same frequency. Perhaps proper security or they might be using the good old security through obscurity trick.

[@ZanHecht]

@@bigclivedotcom I know I'm replying to a very old post, but there are plenty of contactless smart cards that are powered entirely by the reader and don't need any power on the card. Instead of transmitting a static ID number, they function just like a regular smart card: the reader sends a code, the card encrypts the code with it's private key, and it sends the encoded code back to the reader. The reader than attempts to decrypt the encoded code with the card's public key, and if it matches what was originally sent, it knows the card is authentic. Since the card never transmits it's private key, a cheap Chinese gadget can't duplicate it. It could also be just a different frequency or format.

Where did u found that Jack Daniel's Chip? That one is still missing in my collection :p

[@Swenser]

Why isn't this functionality in smartphones? I have nfc phone but not recognising the keycard at all.

[@Vanamonde96]

There are different frequencies being used rfid is actually 125 khz but there are other but that one is more commonly used and phones use nfc and its frequency is from 30Mhz to 3Mhz but the the frequency that phones use 13.56Mhz I mean there are all the same thing but the phones cant read 125Khz 13.56Mhz is a standard that phones use

Casino's..Great description 'Crime done in style'

[@chems]

19:41 what about that chip next to your pinky?

[@ronniepirtlejr2606]

You bearded devil you... a hacking you shall go :>

[@8bits59]

That beeping drove everyone in the house crazy. love the video, very educational and informative!

[@sunhuatom]

125khz rfid systems are now rare for access control. Instead, 13.56MHz rfid is much more secure, and there is no way you can copy a card without knowing all the memory access code. Some 13.56MHz rfid like mifare, the circuit inside the chip has been arranged in a secured fashion, such that it is very hard to hackit even by directly probing the silicon die. however, 125khz rfid has longer reading range up to several meters. All you need to do is to increase the transmitted power from the reader. And you can setup memory access code for improved security, moreover, the unique TID could be used to generate the data inside the chip

[@paulstewart3216]

I'm using an EM4095 RFID front end IC with a PIC18F to lock a little food-theiving bastard out of our cat flap. It was a bit of a bugger to tune (taking turns off the coil, stonehenging tiny 250V caps and suffering a USB poo-scope) but is coming along nicely - I overcomplicated it by having it log data wirelessly to a PC-based TCP server. The IC's application note gives a reasonable tutorial in the analogue stuff (I had no idea what I was doing, but got it to work from this): www.emmicroelectronic.com/sites/default/files/public/products/datasheets/an404.pdf

People playing the drinking game must be going nuts at about 19:39 ;)

[@stephenhalliwell4720]

Love your videos Clive. Thanks

[@AureliusR]

The chip at 17:40 is an 8052 microcontroller.

[@abhishekmaurya528]

what is the tiny chip in that white card?

[@chaos.corner]

You can buy the chips separately. The company I used to work for made custom tags for certain industries. The white cards come apart if you soak them in acetone. I got the coil and the chip out of one and laminated them. Good for illustration.

[@YossNutt]

"let's get the notepad" = shit's about to get real!

[@sparkyprojects]

Part of my last job was security, i looked after the access control, are you sure it's not Wiegand ? we used Wiegand/HID readers, small ones about 2" x 3", to bigger 3 foot x 2 foot which were designed for using from a vehicle. I think the longer range is more about the size of the coil, though there could be a few more turns. Shorting the reader power feed 'should' blow a dedicated fuse for that reader, which would then show a fault at the security hut

[@rupertrooksby]

+Sparky Projects Correct, Wiegand. The Weyland Corporation was "The Company" in the Alien films.

[@VOLTRONDEFENDER4440]

Clive duplicators cannot clone tags that are encrypted!!!!!!!! It cannot duplicate sato access control fobs!

[@godzil42]

The Nuvoton chip have no RFID at all inside: www.nuvoton.com/hq/products/microcontrollers/8bit-8051-mcus/standard-8051-series/w78e052d/?__locale=en so either another components or it's 100% software RFID

[@Onkel.Moetrik]

Hi You don't even need that reader anymore. Any smartphone with NTC and a free app will copy most cards and fobs...I can recommend NFC Tools and NFC ReTag, but there are many of them. You can even copy the card/fob to the phone . Neat.. :-)

[@dilpagalho4306]

Nice teardown...just a few humble suggestions (yes, I'm aware it's 2 yrs old). Please get a macro lens or USB microscope for close up videos and try to edit the video down. Bit too much rambling. But thanks for the video. I'm enjoying some of your other videos too. I'll check your more recent ones and humbly suggest improvements. Take care. :)

[@someonesomewhere1240]

If you have a modern-ish Android phone, try installing one of the many NFC reader apps. It may be a 13.56MHz chip, and many phones can read them. But you need one with an NXP chip to read the Mifare cards.

[@coachabdullah2960]

I have this unit but I haven't installed it yet. One of my friends told me not to because he found the owner's manual online. He's claiming that a person who has the 'programming code' found in the owner's manual can actually reprogram it gaining access. I want to know if this is true. If it's true, I definitely won't be installing it. It wasn't expensive so I'll take loss and invest in something a little more secure.

[@cezarvieiracoradi1411]

Can This blue machine copy encrypted fobs? I've lost my fob and the security company doesn't want to give more because I I've already lost some what it's bad but unfortunately happened. And nobody is able to copy it, I don't know what I'm gonna do. I can't borrow from my friend all my life.

[@Kholaslittlespot1]

You can even get tiny, passive RFID detecting stickers that will fit on a fingernail. Pretty cool but the range must be short. I've been playing with the basic MFRC522 (13.56mhz) reader/writer as one of my first Rbpi projects (also incredibly simple circuitry), so this was informative. Thanks again Clive. You're a legend.

[@bigclivedotcom]

If you mean the NFC fingernail stickers, they are really just designed to be powered by the magnetic field from the Phone's coil.

[@Herp0]

i have a 1$ rfid reader i got off ebay, and i have it hooked to my computer and when i scan the tag which its numbers are 0006188915, lol it brings this video to 11 mins and 26 seconds and i can just keep doing it so i hear Eh, Eh, Eh, eh in fact ill just draw. over and over and over.

[@28YorkshireRose12]

Somewhere, in a vault, in a bank, in London, there is a tin despatch box with my name upon it. And do you know what? You need a metal key to unlock it, and a pair of scissors to break the tape seal, so these things can beep and squeak and squawk and sing and wail until Domesday, and you can't get in! How far removed is this from the kind of security you get on modern cars? The ones that you can steal with a code reader and a relay receiver? It's frighting how easily some people are able to hack this stuff. I remember our last house, and the key that was so old that none of the local locksmiths could cut a spare - now that IS security!

[@conradbusuttil3592]

Can anyone help me refresh my mind please, I once programmed an RFID key fob with my hall porter by cutting off power supply and back with a sequence that I don't remember any more. kind regards

[@julienyee4228]

Is it possible to copy UID from NFC tags compatible with mobile phones (iOS, Android) to another NFC tag?

[@rodrickbourque]

Hey Clive! I have 3 RFID implants in my hands, 2 in the right and one in the left. All different frequencies/protocols. One is 134kHz FDX-B, one is 125kHz EM4305 (Re-writable, same protocol as your orange RW fob) and in the right hand I have a 125kHz FDX-A. Check my video of me using one of them. (That big scar is not from the implant, that's from a dremel accident, lol.)It's done by via hypodermic needle (typically 12G or 10G) This was when it was freshly done so you see the entrypoint of the needle (now completely gone). I certainly get weird looks when I go for x-rays :p) kzbin.info/www/bejne/moWZpYt5f8SYntE

[@choke666]

Thats hella cool! The video says private. Darn, im not invited. :(

[@MoonLightGGA]

Ashton Security Inc. I bought the common Chinese card reader as showing in KZbin it works only with my company access cards. But with my building elevator card access and my building car parking access didn't work. It can read my building elevator access card and broke the locking encryption code and successfully copy the card but once i tried it its not even reading the card from the elevator card reader! The car parking card can't be read at all from the card read reader i bought. Please if you know any better card readers and can copy and encrypt the codes give me the brand name so i can buy it and test it as i tried to search but all my tries was useless . Thank you so much

[@clems6989]

Idk why stores have not gone to rfid rather than bar codes. They are cheap enough now. You could push your buggy thru a reader, pay and go...

[@Stainless316L]

Hi is ther a scanner for 153kHz PAC Tokens. I can't copy it with the 10 settings Chinese reader writer. Hope so one can advise me

[@marcse7en]

Hi Big Clive, Small Clive here! The thumbnail looks like you're holding a tiny CRT TV! 📺

[@samiraperi467]

Search for DEFCON, CCC and such, there's lots of stuff on rfid weaknesses and other interesting stuff.

[@michaelosmon]

Holy cow man I seen quotes once for 500 long range rfid tags and 2 readers for cars/gates it was like $80k installed

[@andrewmoon9576]

so in theory if the voltage is high enough and your mobile is compatible with wireless charging you could be out shopping your mobile phones dies so you walk up to a rf door lock and charge your mobile enough to send that text or make that call you need to make? lol

[@speeddemons4333]

Hi I was wondering if anyone could help me i want to make a rfid window alarm with the same pad as you except if you open the door without tapping the rfid fob then it would set an alarm off is this possible and yes I know you can buy kits for that but I am too poor for those can someone help please

[@grahamtangomike1880]

Clive.. Couldnt you have opened the device itself and run a very thin (single) line of copper around a particular area therefore acting as an aeriel?

[@felenov]

2:16 ah, the nuvoton microcontroller. Classy

[@refraggedbean]

to get one of those pannels off the wall I would pop it off with a crowbar, if I was going to take it off, I would rather go with a more smart tech, which I will not mention, because I don't want criminals to know how I would do it

[@send415]

How do i program the reader? i have come chinese hotel door lock they dont provide front gate access control im thinking to put rfid reader there but how do i copy the rfid info from the Chinese system to the rfid reader?
