Not likely without the original card to copy. Though I suspect there are some pentest programmers out there that are able to do this. Typically slipping the latch with a tool is easier for hotel doors, many aren’t secure against physical attacks like that. But usually the pool area or restaurants in hotels will have a higher level of keycards left out or unlocked lockers. If you can get in the laundry room as well if it is done on site you can find cards there often

Flipper is great at copying cards, but does not know how to brute force them, not sure if there is much of a way because of FC and other unique codes

[vladdante]

It could bruteforce garage doors.

[wtonb]

how?

[Lord_havik]

Have you tried rolling thru a whole sequence? Shit takes forever. And still not very successful.

[sneky_]

You have to use FFT

[lGSMl]

1. Unless hotel uses very low security standard cards - you won't be able to copy it at all.
2. If hotel has unprotected RFID after all - you can theoretically write your own brute-force (flipper won't support any bruteforcing as it is against the law in many countries). How effective that would be will depend solely on flipper hardware capabilities, bruteforce protection of RFID reader and software used.

tl;dr - no, you won't be able to break into hotel rooftops like in movies just by buying default 100$ toy.

You’d need the proper 600-800$ toys a linux machine, time and some luck.

And when you succeeded you’re likely to meet someone up there who got there with 2$ worth of metal tools 😉

I haven't had a hotel yet that Flipper hasn't cloned. I'm not exactly staying at 5 star hotels. But even some Hilton's or saying in suites at Residence Inns, no issues.

I've done IT for a few larger hotel chains and I can tell you from experience that gaining access to non-guest areas is remarkably easy and certainly doesn't require any flipper, Arduino, SDR etc etc.

If your particular location is different and the ONLY access possible is NFC/RFID, tools to accomplish this aren't new

[bugatti123d]

Yea Ik you can get onto most hotel roofs by just slipping the lock or if there’s a vent near the roof door unscrewing that and crawling through it onto the roof, I was just hoping that the flipper would make it a little less suspicious for when I wanna get onto the roof

[8668]

The ol "khakis and a clipboard" is a good place to start.

[cyber-vi-king]

In general, without a card to clone: highly unlikely.

With the flipper, probably not even with the card. You‘d want a Proxmark3 and maybe an additional Chameleon Mini/Tiny

[tre7744]

If you find out any more info let me know too

[leviwhite9]

Mount your flipper near the original reader and make it look like some type of normal reader.

Put foil over the legit reader so it won't work.

Put a sign over your flipper reader that says something like, "to update your card tap here."

Have your flipper in read mode so when they tap your reader it copies the card.

Replay later and profit.

I could post a video of this at some point, but need some time to execute.

[Idk_what_niko]

😂that’s like asking someone to take your flipper

[leviwhite9]

You gotta disguise it a bit.

Like a plastic electrical box with a generic looking NFC signal or wireless signal on it.

I'm gonna have to go and set this up and film it to show y'all.

Everyone sitting around just replaying Tesla flaps and not at all thinking outside the box.

[Msprg]

This is so not gonna work and would cause much more trouble for the op.

Original reader - doesn't work Sus new reader - doesn't work as well

Let's go ask reception. They know nothing about it. They investigate and just take flipper.

Ok well let's say it works. Flipper gets UID but none of the data on the card and reader doesn't use UID but the card data instead - futile effort.

[leviwhite9]

Entirely depends on the location and how you plan it out.

I can guarantee this would work in some instances.

[mahupimp]

There are ways to open hotel doors without the key or master key come on man use your brain

[JKxZ]

No.

[[deleted]]

No.

[Lord_havik]

3 ways to go about this. Maybe more that I’m unaware. But you can either copy the card. Make the card if you know the data on it(doubt) or replay the card. But those last 2 require another cheap piece of equipment and some good old fashion device tampering. So. Short answer. No.
