Hey everyone, the blue cloner is making a come-back… only this time it supports 3 different types of chip IDs! We’ve been able to get the firmware to support EM410x, EM42xx, HID ProxCard, and AWiD cards too!
Its up on the site and the description says it still sets a password. The Blue Cloner will write the source ID to your T5577 based product, then set a password after writing. This protects the target T5577 chip from other malicious writers, but it also means your target chip requires a password to write data to it again. This does not affect the Blue Cloner – it will continue to function properly – but if you wish to write to your T5577 chip using any other writer, you will need to ensure the writer can authenticate first using the password 51243648.
I hate devices that try to be too clever. Here the password thing is exceptionally stupid, because either it’s secret and you’re locked out of your chip after the cloner is done writing, or it’s public (as is the case here) and it’s just a minor extra annoyance if you’re a maker of “malicious writers”.
I’m assuming this is the command line you’d find if you were to write to the chip with a blue cloner then read it with a PM3… for the purpose of deleting it and thus removing the password? Sorry for the confusion, I’m pretty new to all of the RFID programming stuff
Follow-up question, if you intend to only use the blue cloner and not upgrade or switch cloning/writing devices, what harm does the password do, even if it’s viewable as was mentioned earlier?
That’s the command you would use on a proxmark to write a new ID to an xEM or the LF side of the NExT if you had already written to it with a blue cloner which had password protected it. You would have to issue the command like that every time you wanted to write a new ID.
It doesn’t do any harm, as long as you always use a blue cloner that has that specific password and you’re needs are addressed by the limited tag brands that a blue cloner supports (HID or EM). Lots of implantees want more than that, though. For example, my workplace uses a different type of LF system. The blue cloner wouldn’t work for me, and testing it out could lock my implant down so that I have to buy a proxmark, or get it removed. That’s not even considering the data tearing issues that the poor antenna coupling can cause.
