Episode notes
Accidental Discovery of CSAM
- Krzysztof Franaszek found a US government ad next to explicit content on imgbb.com during unrelated research.
- This discovery prompted him to investigate further, ultimately uncovering ads for major brands next to CSAM.
CSAM Detection Challenges
- Law enforcement agencies use a hash database of known CSAM images to identify and remove illegal content.
- Platforms like Facebook use this technology for automated scanning and deletion, but altered images can bypass these checks.
Altered CSAM
- Some of the CSAM found on imgbb.com were not exact copies but altered versions of existing images.
- This included AI-generated deepfakes, which can evade traditional hash-matching detection methods.
