RFID Credit Cards ...... are NOT safe.

Re: RFID Credit Cards ...... are NOT safe.

I came across a website where these teenagers showed how these new RFID technology is easy to crack. In the video they drove to some gas station which accepted RFID tags outside on the pumps....they pointed some antenna attached to their laptop and pointed it towards the Scan area on the pump .....they did something and were able to fill up the gas and they just simply drove away withouth anyone noticing.

** These banks think their encryption is safe but its really not. 3des, des, DES DUKPT, or whatever method they will use...its all piece of cake! **

things to watch closely in future. Satellite hacking...an interesting area to monitor for next 10 years.

The guys in link (by Tofibaba) did NOT break 3DES or AES ....... it was actually an unknown commercial algorithm by Texas Instruments. One major weakness in those DSTs (digital signature transponders) by TI was the use of 40-bit key. And it has been long ago known that this size of keys is easily breakable even by brute-force attack ...... and that's what they did.

Some of the cryptographic algorithms are pretty good, specially AES, 3DES and some non-symmetric ones . It's the fault of the vendors who do not implement them properly ..... in this case TI.

If you use 128-bit key for AES ..... it's NOT a piece of cake at all. Not even if you run super-computers. Unless some mathematical flaw is found in it .... but so far there's none.
