From Nikon USA:
To users of the Image Authentication Software
Thank you for choosing Nikon for your photography needs.
We have confirmed that reports of a vulnerability with the Image Authentication Software that results in false image authentication have been posted on third-party websites.
These websites state that image files can be modified so that the Image Authentication Software falsely authenticates even images that have been enhanced or altered as unchanged from the original image captured.
The information posted on these websites is based on independent analysis of Nikon products by a third party.
If you have additional questions about this Service Advisory, please contact Nikon Customer Relations at 1-800-Nikon US (1-800-645-6687), 8am to 2am (Eastern), 7-days-a-week.
