I have never paid much attention to the protection of firmware or the technical issues revolving around such schemes...was wondering: I recently saw an add for a UK based group that says they can take a PIC OTP micro and read the prom (for a fee, of course) - How the heck is this done?? I have my suspicion that they (somehow) magically peel off the ceramic coating (without destroying the chewy center), get a circuit mask and 'micro probe' the I/O of the IC...they then download the secret recipe to the afore mentioned 'chewy center'. Is this close to accurate?? How is it 'done' ??? -Just Curious
