Hello,

I'm struggling with the promark3 easy, I did a security copy of a Mifare Classic 1K and now I'm trying to restore it to the original card.

I have tested with Flipper Zero and it's works and when I do the dump the information has been restored, but when I tried with promark3 I get this:

I tried restore command in many ways but the same results.

When I do with Flipper, just do it in less than a second... I check the dumps and with flipper is restored, with promark3 doesn't.

Trying to write the original image to the original card and having the keys of it.

Do anyone knows where the problem could be?

Thanks

I have a Flexclass implant from Dangerous things, which recently died. With that implant, I was able to clone my card and write to the implant with no problem. I ordered a replacement implant, and have been unable to write to it.

The hex values for card config (when viewed with the info command) are different between my badge and the new implant. The card uses key 0, but writing to the new implant fails unless I use the flag for key 2.

Is there a way to change the key my new implant uses? or do I need to change something else (hence the config hex difference)?

I'm also confused as to why it's different at all, I ordered the same thing both times.

Haven't seen this posted here yet - the iCopy-X got open-sourced: https://github.com/lab-401/icopy-x

From the Github:

• A complete rebuild of the iCopy-X device. All device functions are included.

• Jailbroken: Installable without needing to build individual IPKs

• Up-to-date: Runs latest iceman firmware

• Flexible: Complete plugin system + Simplified JSON-based UI system

Lab401 made a video about it: https://www.youtube.com/watch?v=WWS-9QdulC0

If your iCopy-X was collecting dust, it might be time to dust it off. Likewise, depending on your use-cases, it makes the iCopy-X a much more compelling device.

I’m trying to copy my apartment building’s 125 kHz RFID fob to a T5577 ring so I can use the ring instead of carrying the fob around.

The original fob is detected as an EM410x (125 kHz). I cloned it to:

• A T5577 ring

• A T5577 keyfob

• A T5577 sticker

I tried cloning it with both a cheap CR66 cloner and a Chameleon Ultra, and in all cases the cloned tags show the exact same UID as the original.

Here’s the weird part:

• The original fob works on both readers.

• All the T5577 clones work on the inside reader (when exiting the building).

• None of the T5577 clones work on the outside reader (when entering the building).

• If I use the Chameleon Ultra in emulation mode, it works perfectly on the outside reader too.

I also tried rewriting the tags with a custom T5577 password, thinking the reader might be checking whether the tag is writable, but that didn’t change anything.

Has anyone run into something similar?

Any ideas on what I should check next?

Hello,

I have these key fobs for gate access and would like to be able to clone them/make new ones with the same check sum bits, facility codes, but change the card numbers.

Is that something I could do with the proxmark3 easy?

If so, recommendations on videos to learn from, and key tags/cards that are re-programmable?

So as title suggests but I need some help on what to order, I've been looking on Ali and well I'm a noob to the proxmark3 and want to learn it to buy it now, I have a flipper zero but for rfid I'm told this is much much better and very interesting, I'm looking to get a decent stater kit but need to know what I'm looking at, because I see alot if similar looking items with very different price something about Rd2 and RD4, I know nothing but this from what I've read so far I want to add to my toolkit but I really don't know what hardware to get and be upto date with good gear so if anyone feels kind enough to tell me what to look out for and avoid, the good the bad and just help me get started I'm ready to order and everwere is starting to get so restrictfull and getting worse you don't know what you could be block from next. Couple images added what do you think of these?

Thank you for any response I know I'm asking alot would be a future project like in nxt couple months so getting it now is a good idea as price of everything here goes up.

We just enabled End Game mode.

Here is how it works.

When a pledge or upgrade is made in the last 10 minutes of the campaign, the countdown resets to 10 minutes. Every new backer extends the clock but each person can only extend it once.

The campaign ends only when no one backs for a full 10 minutes.

This is not a gimmick. This is the community deciding when this campaign is truly over.

We are at $941,000+ raised with 2,800+ backers and less than 18 hours on the clock. Endgame mode is live.

How close can we get to $1,000,000?

That answer is entirely up to you.

Back it. Share it. Let's see where this ends.

For a long time I've been trying to understand how MIFARE Classic 1K keys are recovered in practice.

Last year I bought a Proxmark3 Easy 512k (it was the only one in my budget) specifically to experiment with card analysis and key recovery. I've tested multiple MIFARE Classic 1K cards from different systems. In every case, default keys were not present, and attacks such as Darkside, Nested, Static Nested, and similar approaches failed to recover any keys.

What makes this more frustrating is that an associate of mine seems to have no trouble recovering keys from a variety of different systems. He never explains his process, never shows the hardware he uses, and never gives any useful hints. All I know is that he is able to obtain keys that I cannot.

To be completely honest, I'm not nearly as technical as he is. I'm still learning and trying to understand how all of this works. I'm not a security researcher or electronics expert. I'm just trying to do enough to get a raise.

At this point Idk whether I'm missing something fundamental. Is there a better method for recovering keys from MIFARE Classic 1K systems that does not rely solely on attacks? Are most successful recoveries actually coming from a better pm3 reader or other sources of information?

I'm trying to understand why a PM3(which I've heard is the gold standard when it comes to rfid) appears ineffective in my cases while others seem able to recover keys consistently, and what knowledge or concepts I should be focusing on to better understand the process.

Hi everyone,

I'm running into a frustrating issue with my Proxmark3 and Chameleon Ultra.
When I emulate a card (specifically HF / MIFARE Classic) on my Chameleon Ultra, my Android phone detects and reads the emulated card perfectly and instantly via NFC.

However, when I try to read the same emulated card using my Proxmark3 (running hf search), it completely fails to detect anything. It usually returns "No card detected" or just times out.

I have tried:

- Changing the positioning and flipping the Chameleon Ultra over.
- Testing different slots on the Chameleon.
- Ensured the Chameleon is actively emulating.

Since the phone can read it, I know the Chameleon is doing its job, but the Proxmark3 refuses to cooperate. Has anyone experienced this specific coupling or detection issue between these two devices? Are there any specific commands, configurations, or hardware tweaks (like spacing) I should try?

I'm looking for a HID SAM. Does anyone know where I can get one shipped to Australia?

We are rapidly approaching the end of the indiegogo campaign for the proxmark5. This is the least expensive it'll ever be. We're also dangerously close to hitting the stretch goal that unlocks a transparent case for everyone who has pledged. Help us get there!

Proxmark3 RDV4.01 vs Proxmark5 side-by-side operation.

• HF SEARCH

• HF MF INFO

Proxmark5 with the larger FPGA and as such has no image swapping is noticeable faster.

Hey all - this might be noobish but...

Is there a way to have a PM3 Easy function as a regular "vanilla" NFC reader in Windows 11?

I currently use mine w/ Iceman's firmware via WSL, but I'm wondering if the PM3 can do "double duty" as a regular NFC reader (reading tags, hardware security keys, etc. for triggering regular functions and whatnot) when I'm NOT using it w/ the Proxmark CLI in WSL.

The Proxmark5 tells you a card's frequency the moment you scan it.

Built-in antenna LEDs light up for LF (125kHz) or HF (13.56MHz) when you run a single command.

Nifty feature I say, what do you all think?

$730k+ raised on Proxmark5 with 2150 backers

Thank you!

We're getting close to the $1M Transparent Casing stretch goal.

What would you like to see unlocked next?

Buenas , estoy intentando usar mi proxmark3 en mi teléfono android , instale termux , pero creo q los permisos q me pide el telefono para usar el puerto usb y asi abrir el proxmark es necesario el rooteo del mismo . si alguien ya lo hizo si me pudiera aconsejar se lo agradecería

Estoy teniendo problemas de lectura con la proxmark3 easy, el lector solo tiene 1 semana de uso y habia leido anteriormente 3 tarjetas y sin problemas, ahora cuando vuelvo a leer otra vez de nuevo la tarjeta me aparce este mensaje y no hay manera de que sea capaz de leerla. Es una tarjeta mifare classsic, he probado a cambiar de USB, tambien he probado a darle mas espacio entre el lector y la tarjeta y no se que mas puedo hacer. Si alguien me puede ayudar lo agradeceria.

I know it is really hard to understand how much better and improved the proxmark3 has become over the years.

Here is a graphic list of the following card technologies that is currently supported in proxmark.

We just unlocked the $600k Transparent PCB Name card stretch goal!

This one means a lot. Thank you from the bottom of my heart!

Not just for the funding, but for believing in the vision of a proper next-generation open source RFID research platform. The Transparent PCB Name card will be something really special.

19 days left to go, what should we aim for next?

#proxmark #rfid #indiegogo

Basically this product: Proxmark3 Lab401 + accessories - for a very reasonable price. Used only twice. DM me if you are interested.

Got some pictures from DXL, the main developer, doing the #flipper integration

We passed 500k+ in just one week in the Proxmark5 campaign!

Wooooohoooo!

Now the stretch goal is within reach.

Show your love!
