The short version
A data collector shall disclose any breach following discovery or notification to any resident whose unencrypted personal information was, or is reasonably believed to have been, acquired by an unauthorized person. The disclosure must be made in the most expedient time possible and without unreasonable delay, consistent with the legitimate needs of law enforcement.
Two features of the Nevada text stand out. The chapter as served contains no notice to the Attorney General or to any other regulator. It also contains no risk-of-harm exception, so the duty turns on acquisition of unencrypted information rather than on a judgment about likely harm.
