Researchers from Ghent University and KU Leuven have published the first white-box analysis of Microsoft PhotoDNA. Their findings reveal that PhotoDNA's piecewise-linear hash function can be exploited within seconds on a standard laptop to generate exact collisions, produce false positives matching CSAM hashes, evade detection, and partially reconstruct source images.
