Hello people,

So I recently was playing around with some NFC apps, and I found out my OV-Chipkaart (Dutch public transit card) was read by my phone. Unfortunately I got a lot of numbers and stuff I didn't understand. Does anybody know more about this?
[NFC Hacking] PieP:
The card is encrypted. If you get the key (there are a couple of articles on the internet which tell you how to get it), you should be able to read the entire card. Without the key you can only see the expiration date.

I saw it was possible to add your own MIFARE key in the TagInfo app. The only thing you need to get this key is an RFID-reader for your PC and some processing power (and the appropriate software).
[NFC Hacking] cu2080:
cool

Thats so cool
[NFC Hacking] htcsnap93:
My acces card for school does the same. Found this out because everytime i put my phone kn my wallet it made a sound.
[NFC Hacking] buraki:
UID

Each contactless chip (incuding the Mifare you have) has a unique id which is accessible to any contactless reader, in this case you phone. Unique id enables the reader to overcome collision for reading one chip at a time. This is is probably used as the id of your card by the system it is being used.

hey on they internet i found this :

http://www.ov-chipkaart.me/forum/vi...sid=601115f083127a3a86069b25feebdb43&start=30

i tested it on my personal ov chipkaart but it didn' t work because i haven' t made a dump off the card. i haven' t got a reader for it so maybe if a xda that lives in Rotterdam/Cappele a/d Ijssel is kind enough to make a dump for me :)
[NFC Hacking] ahvipardik:
I also recently checked my bus-card and the phone could read some of the info in the card, so i was wondering if it is possible to clone the info in the card to some other nfc tag, which would be cool, and also if i use the phone as rifid reader, mentioned above, connected to pc with usb then theoretically it would be possible to reprogram the card...?

And also another question, is it possible for the phone to send out same info which is on the card so i could use phone instead of bus-card at the bus?

EDIT: I read previous topics and realized that this is impossible.
[NFC Hacking] Factionwars:
The ov-chipkaart part is now available and working in the source of github/wandcode/farebot. I have tried and confirmed that this is working. You will need to crack the MiFare classic keys first, this is only possible on a ov-chipkaart by NXP-semiconductors (so not the Infineon version)
[NFC Hacking] leto78:
I don't have a RFID card reader... Is it possible to dump the chipkaart keys with the Samsung Nexus and then crack the keys with the PC?
[NFC Hacking] magicyello:

Funny

Now to find out how to upload vitual cash
[NFC Hacking] Factionwars:
No that's where the power of chip-cards come in play. There are no keys on it who a external device will receive and decipher. A Mifare Classic card has a built-in authentication system which you will have to pass to read/write onto the card.

The only possible way i could think of is to take the known key from the card, generate a dictionary on a computer and then bruteforce with a phone. But i think that would be more time/hassle then buying a 20 dollar NFC reader.
[NFC Hacking] leto78:
All the Mifare card readers I could find cost at least 40 euros... Do you recommend any cheap ones?
[NFC Hacking] Factionwars:
Ah you have to take a look around, there are loads of people owning a acr122u(touchatag) who bought them when the ov chipkaart got cracked, prices have been rising i guess. Try second hand ;)
[NFC Hacking] dragonwith:
Anyone heard about the news today? The OV got hacked again.

You guys know any of this?
[NFC Hacking] Factionwars:
Here a hidden post on the details http://www.totalov.nl/m/index.php?type=n&n=166

I have been on it all morning, and it seems to be more of a theoretical hack rather than a real PoC. I also still don't understand how you could attach a sticker to a nfc card and the reader will read the sticker instead of the nfc card, it will read both in my logic.
[NFC Hacking] wm6.5:
Any news or how to's available.

Hi guys any app or news available on how to do this.:eek:

If anyone in holland is willing to help me with a dumpfile of my 0V chip card for a reward, sent me a pm please.:good:
[NFC Hacking] dragonwith:
Isnt it kinda obvious that you have a huge sticker on your OV. Like Checkers can just take of the sticker and they can see its fake.
[NFC Hacking] Factionwars:
No Mifare classic stickers can be very small, and then again you can also attach it to the card holder it's in and when you get asked to take it out you just have bad luck. Though i am more interested in the Tech and Security rather then abusing it.
[NFC Hacking] DamianSewo:
Hey guys. I'm willing to help and work together to make this work. I've also noticed that the forum of the last hack, ov-chipkaart.me is down. Does anyone know anything about this?
[NFC Hacking] Toxicity123:
The sourcecode of Farebot is avalible on github if you didn't already find it.

Since it can already read the data it must not be hard to be able to write it back to a new tag..

If you need any help or a Mifare reader you can contact me.

[NFC Hacking] Zenety:
http://web.archive.org/web/*/http://ov-chipkaart.me

That one yeah.

What is the difference between the source code of Farebot on Git and the one in the Play store? Neither of them have encryption keys and I do not own a Mifare reader :(

Suddenly alot of OV-kaart hacking activity because of: http://www.nu.nl/tech/3493455/hack-ov-chipkaart-met-sticker-en-app.html ?

http://tweakers.net/redactieblogs/89527/paniek-is-de-ov-chipkaart-echt-weer-gekraakt.html

Anyone know a site where I can buy a Mifare Reader?
[NFC Hacking] DamianSewo:
I'm trying to get more information about this method for the last couple of hours, but I can't find the specifics. The last hack (of 2010) does not work anymore because when you are checked by a conductor at the end of the day the information of the pda of the conductor goes through the central servers and your (anonymous) ov card is blocked. This new method uses the cheap nfc stickers instead of the old 7,50 anonymous cards. So in theory you can use a new sticker every day (around 1 euro). But the whole issue is the unique code of the card. So the new method needs to be fundamentally different.

And if you can do it with a android nfc reader you also can use a mifare nfc reader...
[NFC Hacking] Factionwars:
It's most likely a Hoax from a kid called marcel balk. Please keep this topic open for people who just want the ease of reading their cards and not abusing it and doing something illegal (not allowed in this forum).

update:

http://tweakers.net/redactieblogs/89527/paniek-is-de-ov-chipkaart-echt-weer-gekraakt.html

The keys are unique for each card and thus you will have to retrieve them yourself using MFOC or a friend might be able to do it.

to all: This is a development board, not a board for people who don't want to pay for the public transit.
[NFC Hacking] Zenety:
Well I travel for free during the week so I don't mind.

If I were to buy a ACR122U NFC Reader would I be able to read the keys from my OV-Card? Then write the keys to Farebot and I will be able to read my Balance?
[NFC Hacking] Factionwars:
Yes :), you could even to be safe of not writing to your card only crack the A keys and not the B keys and you can just put the file you get from MFOC/MFOCGUI on your sd card and open it with Farebot. After that every time you touch your phone with your OV card it will quickly scan it and display your card information.

I use it a few times a week because i use it for bus travels :)

ps: i own a acr122u myself :) (touchatag is practically the same) you can also look at the supported devices by LibNFC because that is the lib used to crack the card.
[NFC Hacking] Zenety:
Thanks! Reading my balance would be so convenient. Instead of having to go to a bus/train station to check it.
[NFC Hacking] Toxicity123:
Put a dot between huuf and info for some sample dumps.

Put a dot between goo and gl for a lot of information about this hack.
[NFC Hacking] Zenety:
Came home from work, asked my dad about it and he had a ACR122U NFC Reader just lying around. So my OV-Card is being read right now. It is taking pretty long. Anyone know how long it will take?

At sector 22: Probe 465

Used an older version of the program, rerunning it now with the newer version.

Edit: Didnt't work, got an error that I needed to try it with more probes.
[NFC Hacking] Factionwars:
I can see you have a decent laptop. So it should take no longer then 30 minutes i guess. You can change the probe value how are the settings right now ?
[NFC Hacking] Lux026:
I have the ACR122 card reader which can read the ov chipkaart on my computer. I also have the app farebot installed on my Samsung galaxy s3 (with nfc). What do I have to do now? Do I have to buy a nfc sticker? Does someone know where I have to order this?
[NFC Hacking] Zenety:
Used the latest mfocGUI, took about 45 minutes to an hour. It's just an Intel Core i3-370M with 4 GB RAM. Not that fast. I don't have a clue how to increase the probes. I'll search the web a bit. Could it be my OV-Card can't be read?
[NFC Hacking] Factionwars:
Very much likely that you have the new Infineon SLE-66 chip instead of the NXP mifare. This new chip emulates the Mifare protocol but protects it from the bruteforce on the crypto-1 algorithm. So instead to read your OV card you would need an old one or somebody with a Proxmark 3 to sniff the keys.
[NFC Hacking] Zenety:
Well that kinda sucks. Proxmark is a bit expensive heh. Thanks for the information anyways!
[NFC Hacking] Toxicity123:
You can't. There is no public app avalible. You would need to make your own application to write OV-Chipkaart data to a NFC sticker.
[NFC Hacking] Lux026:
Aren't there numerous apps in the play store to write data to a NFC sticker/tag? For example 'NFC Tagwriter by NXP' would do the job right?
[NFC Hacking] Justmebeingnew:
More info

A major tech site has reported about the hack and also give more information: arstechnica.com --> dutch-public-transportation-may-be-hackable-with-an-android-smartphone

Also i am reading up on code google com mfcuk witch report to display the key from linux distro`s where it can be ported to android.

So i dont now if this is true ?

And did any one did reachearch on marcel balk ? if it is legit ? becous a lot of media is saying it is true ?
[NFC Hacking] XperiaZ77:
ardly parcce

What's the difference? And how do i know if my ov chipkaart isNXP or Infineon?

---------- Post added at 04:10 PM ---------- Previous post was at 03:59 PM ----------

i wouldnt use a sticker....if the busdriver or trainconducteur comes to check if you're checked in, you can't show a sticker......then you're busted. You need a card. Buy an anonymous ovchipkaart and pay for it with cash, so there will be no papertrail.....and after a while the card will get blocked by TLS but i heard there is or will be an app that can deblock the card through NFC......That app only works on phones with NFC like Sony Xperia Z

---------- Post added at 04:19 PM ---------- Previous post was at 04:10 PM ----------

So with the old cards(2009) i can still use the old hack and it won't get blocked? I also heard there is an ap or will be an app that can deblock the card through NFC on NFC supported smarthphones.......doesn anyone know something about that?
[NFC Hacking] davidian22:
I tried to scan my ov (usable till 2016) with the Farebot, but I don't have the encryption keys. Farebot did not recognize my ov. It does nothing. Is this normal? And will I be able to use my phone as NFC reader to crack the encryption key on my lap/pc?
[NFC Hacking] Factionwars:
Please read the previous comments.

Also I am not going to help you guys with hacking this card for free rides. The sticker idea is ridiculous, and doesn't change a thing because when your card hash is changed without being loggen in the TLS systems it will be blacklisted after 48 hours. So this will even kill the sticker idea. And you would need an old ov chipkaart to clone it, and you would need a magic mifare classic sticker /tag to clone the UID. So please keep this topic open for people who wants to read their cards with farebot because that is just very nice. And for hacking this card I will refer you to the rest of the internet and months and months of research you will need to do:)
[NFC Hacking] davidian22:
Sorry if I was confusing. I am not trying to hack my card or get free rides. But like most of you guys I am trying to read my card because I want to see my balance and more things with farebot. But to the question : is it possible that my card isn't compatible? Because farebot does read the ov of a friend of mine.
[NFC Hacking] Factionwars:
Yes you will need the old card and first crack the keys on a computer. The old card has a NXP mifare classic 4k chip and the new one a in fine on sle-66 so if your card expires in 2016 you have a new secured chip.
[NFC Hacking] davidian22:
The card of my friend expires in 2017. It doesn't make any sense..
[NFC Hacking] XperiaZ77:
all cards that expire after 2016 have the new chip

---------- Post added at 03:33 PM ---------- Previous post was at 03:27 PM ----------

you can googlle NFC TagWriter app by NXP
[NFC Hacking] Thatgrass:
The MiFare Classic 4k chip is easily hackable with the backup/restore method. This was the old OV-chipcard chip. My school still uses the MiFare Classic 4k chip, so that's pretty nice ;)
[NFC Hacking] Toxicity123:
Did anyone find anything yet?
[NFC Hacking] shotormorgh:
I found a cheaper ACR122U on Ebay.. It looks exactly the same but it says on the page:

Not sure what they mean by that, what is crashing anyway? Do they mean flashing?

Anyway, would this one work too? My card expires in 2015.

Let's revive a super old topic.

A dutch news website reported that the Univerity of Radboud succesfully cracked the new OV Chipcard again and that it's possible within minutes. Super curious again :)

Since most readers here will be dutchies: http://www.nu.nl/internet/4023707/chip-ov-chipkaart-en-toegangspassen-blijkt-eenvoudig-kraken.html
[NFC Hacking] :
Here's to hoping someone programs an Android app to dump/crack it on the go. I want to load it into Farebot so I can leave the card at home.
[NFC Hacking] Zenety:
Exactly the only thing i'm hoping for. Or just the capability to check my current balance.

As for more exciting news: http://tweakers.net/nieuws/102579/vodafone-gaat-testen-met-ov-chipkaart-op-smartphone.html (A bit old already)
[NFC Hacking] :
You can check your current balance with https://play.google.com/store/apps/details?id=nl.tls.ovchip updates pretty much instanteneously too :)

And I hate Vodafone and T-Mobile, I always want a provider that's on KPN's network. Maybe Tele2 cause they said they'll start offering unlimited data for 85% cheaper than the current providers.

Hello guys, this is my first post here in XDA

i'd like to have some tweaks to increase my Xperia Neo V gaming perfomance, i'm using original gingerbreak, and i'd like to know the best ROMS and kernels, my xperia neo v is freezing while playing ''easy'' games like temple run and fruit ninja, heavy games like GTA 3, Kinectanimals crashes and reboot my cellphone, or just close.

Thanks (::cowboy:
[Sony Ericsson Xperia Neo, Pro] darkerm:
To me Stock ROM is the best and try "Night-elf Kernel"

one thing don't use any task killer/RAM optimizer cuz its slow down your system.
[Sony Ericsson Xperia Neo, Pro] zieju:
Try codename 8 by emanxperia.
[Sony Ericsson Xperia Neo, Pro] szacuken:
Agree :)

Stock 2.3.4 + Kernel Night Elf 9.6 full + delete some unnecessary apps from /system/app/ and you have got the fastest rom that you can have.

Dont use supercharger, nitro busters, adrenaline busters, task killers etc. It's all one big crap... that slow down phone
[Sony Ericsson Xperia Neo, Pro] Ph Oliveira:
So, i just need to change the kernel? The original android suports it? i need to unlock the bootloader to do this? Thanks a lot for the replies :D

I'm using 4.0.1.A.0.283, is this possible to use the kernel you said?

you can try this Super Stock kernel:

Neo V HD games bug

I play HD games like Shadowgun, Skateboard Party HD and when i touch Joystick, and release my finger, joystick is touching same position itself. I use Spacious ICS ROM, but same bug with all ICS ROM's, with Gingerbread everything is OK. Any solutions?
[Sony Ericsson Xperia Neo, Pro] F.A.I.S.A.L:
that is bug with unity 3d engine,

next update of games may solve that problem...
[Sony Ericsson Xperia Neo, Pro] Ph Oliveira:

[Sony Ericsson Xperia Neo, Pro] DeathCzar:
Mate thats exactly what I looked at before telling this. It is GB. For our phone, 4.0.X is GB and 4.1.X is ICS.
[Sony Ericsson Xperia Neo, Pro] DeathCzar:
It is an ICS incompatibility. You'll have to wait for your games to be updated. Or do as I did. Reinstall them. I lost all my data. But it has lesser bugs. But that didn't fix all the bugs though. So if you want to do serious gaming, go back to GB.
[Sony Ericsson Xperia Neo, Pro] F.A.I.S.A.L:
not now, but when devloper update the game,

and i think unity engine is fixed as temple run works with newer updates, so we can expect other games will work soon...
[Sony Ericsson Xperia Neo, Pro] samneov:
Try "GingerBread" instead of "gingerbreak " that might work....lolz:laugh:

well saw that there someting called gingerbreak too...for rooting....:laugh::laugh:
[Sony Ericsson Xperia Neo, Pro] darkerm:
For better Experience I just Downgrade ICS to GB. My neo is Running Stock .62 and Night-elf Kernel 9.6 lite. I tested more than 50+ games in ICS but only Few of them worked and they still had some bug or gilth.

So, my Suggestion is to stay GB and flash a good kernel for better gaming performance ^_^

Never upgrade to ICS if you really wanna play game in Neo ;)

I've had similar issues - phone worked with black screen. I've bought a spare flex ribbon cable on the eBay.

You'll need to remove the back cover, battery, memory card. Then unscrew 4 T and 2 phillips (+) screws. Use plastic card and a usual (-) screwdriver to detach back frame and you'll see the mainboard. Remove it and you'll see 8 philips screws that holds both sliding parts together. Unscrew them and detach the front half with the screen. Then remove 2 plastic patches from the sides of it - you'll see 4 more screws that hold the front part. Unscrew them and carefully pop the parts with a plastic cards. That's basically all. Then you'll be able to connect the new cable and put all the things together in reverse order.
[myTouch 3G Slide General] Nightwolf117:
I know I'm popping in techno's place, but how much did the cable cost?

Also, we met up the other day (he's local) and found the volume buttons and the touchscreen itself didn't work. What will we need? So far I've got:

•Torx T5 Screwdriver

•Phillips Head Screwdriver

•Flathead Screedriver

•A Fully **** MyTouch 3G Slide

[myTouch 3G Slide General] Saem persun:
The cable was $10 plus free shipping from HK. There's a lot of them there available (just "put flex ribbon cable mytouch 3g slide" to the search - I don't have 10 posts yet so I can't make a direct link).

The volume keys contacts are attached to the mainboard with a small flex cable, which you don't really need to detach. Everything you'll need is just to put them into the place under the rocker button when assemblying, and if they are not broken they should work. If someone ever opened your phone, he could forget/missed this operation and probably that's why they are not working.

About the tools: it would be nice if you have screwdrivers of different size. Although I didn't have a torx screwdriver and managed to fix the phone using a flathead screwdriver of corresponding size.

One more thing: the cable has a metal plate. It has the light sensor and green/red LED and goes to the top of the front plate. You'll also need to put a small rubber spacer from the old cable to the new one.

In general it wasn't a complicated procedure - just be careful, don't shuffle different screws together and you'll succeed :)
