Stolen data is most commonly bought and sold on underground online marketplaces and forums that operate on the dark web, along with some closed, invite-only channels on encrypted messaging apps and chat platforms.

Quick Scoop

Main places stolen data is traded

  • Dark web marketplaces : Hidden sites reachable via special software (like Tor) where criminals run e‑commerce style shops for credit cards, logins, IDs, and bulk “fullz” identity packages.
  • Underground forums: Login‑protected or invite‑only boards where hackers advertise new leaks, auction databases, and arrange deals that may later move to private channels.
  • Criminal “data shops”: Specialized sites that index logs from info‑stealing malware (e.g., “Russian Market”, “2easy.shop”), letting buyers search for stolen browser passwords, cookies, and accounts by country, site, or bank.
  • Encrypted chat groups: Private groups on messaging apps where vetted members share samples, negotiate prices, and broker sales that may then be fulfilled via dark‑web sites or direct transfers.

How these markets typically work

  • Marketplaces mimic normal e‑commerce: product listings, search filters, seller ratings, and escrow to protect buyer and seller anonymity.
  • Data ranges from single credit cards to huge corporate or government databases, often bundled and resold multiple times to different fraudsters.
  • The traded information fuels crimes like payment fraud, identity theft, phishing campaigns, and account takeovers.

Why this is a big current issue

  • Recent analyses show tens of thousands of stolen‑data listings across dozens of darknet markets, with revenues reaching into the tens or hundreds of millions of dollars in under a year in some studies.
  • Security researchers continue to track new data‑shop platforms and infostealer‑driven markets, reflecting an active and evolving underground economy as of the mid‑2020s.
