The analysis is based on open data: FBI, Europol and Group-IB reports. The material is intended to study methods of combating cybercrime.
Operation scale (at peak):
Cryptanalysis kills anonymity – even mixers don’t save.
The human factor is the weak link – trusting data to strangers = risk.
Boasting = self-exposure – linguistics + digital traces.

All data is from open court documents and law enforcement reports.
1. Who is Joker's Stash?
Joker's Stash is the largest darknet marketplace for the sale of:- Stolen card data (BIN lists, CVV, fullz).
- Logins from banks (with access to accounts).
- Skimmer dumps (data from compromised POS terminals).
Operation scale (at peak):
- 40+ million cards on sale.
- Turnover: $1 billion+ (according to Chainalysis estimates).
- Administrator: "JokerStash" (anonymous hacker, possibly from Eastern Europe).
2. Key mistakes that led to the fall
Mistake 1: Leak through the operator
- In 2020, JokerStash hired a third party to manage the servers.
- New employee made an OPSEC blunder: used personal email to register a domain.
- Result: The FBI tracked the servers through WHOIS data.
Mistake 2: Cryptocurrency Traces
- The platform only accepted Bitcoin (not Monero).
- Chainalysis analyzed the transactions and found:
- Mixer wallets (Wasabi Wallet).
- Cash-out endpoints (KYC exchanges).
- Result: Connections with real exchangers have been established.
Mistake 3: Public Activity
- JokerStash bragged in darknet chats that "they won't take him."
- Used the same writing style in correspondence (linguistic analysis).
- Result: The FBI narrowed down the pool of suspects.
3. How was he found?
Operation Royal Flush (FBI + Europol)
- Bitcoin transaction analysis → entry to the Binance exchange , where JokerStash cashed out money.
- IP log comparison → servers in Germany and the USA.
- Email clue → provider gave out the real IP of the administrator.
4. Implications for the carding industry
- Rising data prices (shortage due to closure of major supplier).
- Switching to Monero – other marketplaces (for example, BidenCash) have become more active in using anonymous cryptocurrencies.
- Tightening of OPSEC - carders no longer trust "anonymous" colleagues.
5. Lessons for Cybersecurity
