How Cybercriminals Are Using Blockchain DNS: From the Market to the .Bazar

This report examines cybercriminal adoption of decentralized blockchain DNS and marketplaces, explaining how domains like .bazar and platforms such as OpenBazaar are used to resist takedowns and bolster trust among illicit vendors. It cites Joker’s Stash using a .bazar domain as an example, outlines advantages (censorship resistance, tamper-resistance) and drawbacks (public record of interactions, messaging/privacy challenges), and notes that decentralized marketplaces remain nascent with limited criminal uptake compared to other messaging-based trade channels.
