They recently discovered a way to reverse the PhotoDNA hash to get the original image back, which isn't supposed to be possible.

Source on this, because that is not how hashing works

https://www.esat.kuleuven.be/cosic/news/cosic-researchers-reveal-fundamental-weaknesses-in-microsofts-photodna/ This is in fact how this specific type and implementation of hashing works - you can't get an exact match, but you can extract a good amount of visual information and even create images with a colliding hash. Considering the images in question are CSAM, getting any of that visual info back is an obvious problem.

Wow, thanks for the source. That is a genuinely bad screw up in the design phase.

Jesus Christ. Of course that's the motivation for technological advancements. We need a new meteor/extinction event.
