Key Takeaways
- • The Internet Watch Foundation identified 1,014 websites accepting cryptocurrency payments for child sexual abuse material (CSAM) in 2021, more than doubling from 468 sites in 2020 and representing a near-doubling trajectory since 2015 (81 sites in 2018, 221 in 2019).
- • Cryptocurrency adoption for CSAM transactions has accelerated criminal monetization of child exploitation, with the IWF launching a dedicated "crypto unit" to address what it characterizes as an "escalating problem" requiring specialized investigative capabilities.
- • Law enforcement demand for IWF intelligence has expanded globally, with the foundation receiving daily requests from agencies including New Zealand Police, Austrian Criminal Intelligence Service, U.S. Internal Revenue Service Criminal Investigation, and UK Metropolitan Police.
- • The UK-based IWF, Europe's largest hotline for identifying and removing CSAM, is expanding its operational scope to proactively search for crypto-facilitated abuse material and process anonymous public reports alongside law enforcement investigations.
Summary
The Internet Watch Foundation has documented a concerning acceleration in cryptocurrency adoption as a payment mechanism for child sexual abuse material. According to IWF data released in November 2022, websites accepting virtual currency payments for CSAM have demonstrated near-doubling growth annually since 2015, with 1,014 such sites identified in 2021 compared to 468 in 2020, 221 in 2019, and 81 in 2018. These figures were extracted from a total of 250,000 websites containing CSAM that the IWF identified in 2021.
The shift toward cryptocurrency represents a significant evolution in criminal methodology. Cryptocurrencies provide criminals with perceived anonymity and reduced transaction friction compared to traditional payment methods, which financial institutions had begun blocking after evidence emerged in the mid-2000s that credit cards were being used to purchase abuse material. This technological pivot has effectively lowered barriers to participation in commercial CSAM markets.
In response to accelerating crypto-facilitated child exploitation, the IWF has established a specialized "crypto unit" staffed with analysts trained to identify, track, and document cryptocurrency-based CSAM distribution. The foundation is receiving daily intelligence requests from law enforcement agencies worldwide, including New Zealand Police, the Austrian Criminal Intelligence Service, the U.S. Internal Revenue Service's Criminal Investigation division, and the UK Metropolitan Police. This global demand signal underscores the cross-border nature of the problem and the reliance of international enforcement agencies on the IWF's technical capabilities.
The IWF's operational model combines proactive digital searches with passive intelligence collection from public reports submitted through its anonymous hotline. The foundation systematically records metadata and identifiers related to CSAM websites to facilitate rapid removal and law enforcement coordination. As Europe's largest dedicated hotline for CSAM detection and removal, the IWF's expanded crypto capabilities represent an institutional response to a structural market shift in how criminal actors monetize child exploitation online.
