The Justice Department says it's dismantled one of the largest child exploitation sites on the dark web.

Context & Ripple Effects
The DOJ's joint takedown of the 'Welcome to Video' site with UK and South Korean authorities is notable less for the site itself than for how it was cracked: officials say they identified the owner and users by working with Chainalysis to trace bitcoin transactions on the blockchain. That makes this a landmark case for cryptocurrency forensics as a law-enforcement tool against dark web markets.
Over three dozen users of the site face arrest across multiple jurisdictions, and the seizure of some 200,000 unique videos removes one of the largest CSAM repositories from circulation.
Second-order effects
Dark web operators now have to treat every bitcoin payment as potentially traceable, pushing illicit markets toward privacy coins or mixing services — while Chainalysis-style blockchain analytics firms gain a proven, headline case that sells their tooling to other agencies.
Third-order effects
If the pattern holds, large-scale CSAM platforms become periodic, coordinated multinational operations rather than persistent infrastructure, with jurisdiction-spanning coalitions (US, UK, South Korea here; Germany, Netherlands, Europol in the Kidflix case) as the standing enforcement unit.
The trend: Dark web criminal markets are being dismantled less through network exploits than through financial forensics, as agencies institutionalize cross-border coalitions around blockchain tracing.
South Korean National and Hundreds of Others Charged Worldwide in the Takedown of the Largest Darknet Child Pornography Website, Which was Funded by Bitcoin https://www.justice.gov/... pic.twitter.com/IBJvyuDO26
Legally and journalistically, I was in a bind. How could I write a story without confirming the details, but in confirming the details would require me to visit an illegal site? Our lawyers said it wasn't possible. The story died — until now. More: https://techcrunch.com/... http…
This is a vast takedown of a really huge child abuse imagery distribution website. Eight terabytes of abuse material seized; 337 arrested and charged, leading to the rescue of at least 23 minors being actively abused in the U.S., Spain and U.K. https://www.justice.gov/...
Bitcoin is not for criminals. Anonymous coins are for criminals. Cypherpunks and anarchists don't understand that privacy is not anonymity, and observation is not surveillance. https://www.bloomberg.com/...
Jong Woo Son, 23, a South Korean national, was indicted by a federal grand jury in the District of Columbia for his operation of Welcome To Video, the largest child sexual exploitation market by volume of content. https://buff.ly/31gSxQV #hacking #darknet pic.twitter.com/HABwzPR2…
250,000 unique abuse videos recovered from the site; @NCMEC *still* going through them over a year later, but of the analyzed ones, 45% were new, and the site boasted over a million downloads.
According to the indictment, the way the site worked was people would pay to view abuse images using “points”, and points could be obtained by either: a) ~$300 in BTC for six months of access b) Uploading new abuse images c) Referrals So designed to actively encourage new abuse
“The complaint alleges that law enforcement was able to trace payments of bitcoin to the Darknet site by following the flow of funds on the blockchain.” More details: https://www.justice.gov/...
A massive take down of a highly Opsec focused global child exploitation ring. An amazing law enforcement effort against the lowest level of humanity. https://www.justice.gov/...
Bitcoin has enabled and enhanced some pretty heinous online crime: https://www.justice.gov/... But one good thing about Bitcoin is it is not actually all that good, so capture the server and follow the money works.
