Understanding Online Child Sexual Exploitation and Abuse (OCSEA)
An evidence-based overview of online child sexual exploitation and abuse — the most severe category of child online harm. Documents the alarming scale: 88 million+ CSAM files reported to NCMEC in 2022 alone, representing a 329% increase over five years. Covers all major categories — image and video-based abuse, live-streaming exploitation (a growing threat across Southeast Asia and beyond), AI-generated CSAM (now a recognized and rapidly expanding category), and financial sextortion targeting teenage boys. Explains the technological ecosystem enabling these crimes, the role of encrypted messaging and dark web platforms, and how industry tools including PhotoDNA, Thorn's Safer, and IWF hash lists form the first line of technological defense.
