After the test was complete on the previous slide, a photo was AirDropped to another device. The AirDropped EXIF data showed the adjusted timestamp and adjusted location. The only way to even hunt down the original timestamp was to look in a Hex tool, which is shown in the slide above, where we see 2022:01:24.
Here, the tool Frhed was used to scan the Hex of the image for the original timestamp.
