Crypto Rails
Blockchains move value across borders in minutes without a correspondent bank, and dollar stablecoins carried 84 percent of the $154 billion to $158 billion in illicit crypto volume recorded in 2025. While transfers on the ledger are permissionless, the rail still meets regulated institutions at its edges: banks, exchanges, kiosks, over-the-counter desks, and stablecoin issuers that can freeze tokens and produce customer records. The Crypto Rails article traces how scam compounds, North Korean hackers, sanctions evaders, and laundering networks use the rail, where it can be cut, and how blockchain clustering holds up in court.

Crypto RailsMoney Mules
Every fraud needs a receiving account in someone else's name, and the money mule supplies the link between an outside syndicate and a regulated bank. Recruited through fake job ads, romance scams, social media cash-flip schemes, or student debt coercion, mules move proceeds across bank accounts, payment apps, cashier's checks, and crypto kiosks before cash-out typically occurs between the second and fifth hop. The Money Mules article examines the division of labor from recruiters to funnel accounts, how mental state and warnings separate unwitting intermediaries from complicit defendants, and how banks and investigators trace the network behind the account.

Money MulesGuarantee Marketplaces
Chinese-language guarantee marketplaces on Telegram supply the escrow, vendor collateral, dispute arbitration, and Tether settlement rails that allow Southeast Asia's scam compounds to buy stolen data, deepfake kits, mule motorcades, and laundering capacity from strangers. Platforms such as Huione Guarantee and Xinbi Guarantee processed tens of billions of dollars in volume before drawing Section 311 action, OFAC and UK sanctions, and DOJ infrastructure seizures in 2025 and 2026. The Guarantee Marketplaces article maps how public escrow groups work, how operators reconstitute on backup channels and custom apps after takedowns, and the red flags FinCEN's September 2026 scam-center alert asks banks to report.

Underground bankers, hawala networks, and Chinese money laundering organizations move criminal and sanctioned value across borders by separating local customer payouts from international settlement. Instead of sending a direct wire, brokers net obligations on private ledgers and clear balances later through mirror currency swaps, trade-based invoicing, casino junkets, cash couriers, and stablecoins, including the $312 billion in suspicious transactions FinCEN analyzed across Chinese networks and the $179.1 billion A7A5 ruble-token rail tied to Russian sanctions evasion. The Shadow Banking article explains the five settlement channels, distinguishes nonbank credit from illicit underground banking, and lays out a three-ledger method for reconstructing cases.

Shadow BankingThe Dark Web
Tor onion services, darknet marketplaces, autoshops, and bulletproof hosting providers let buyers and vendors trade drugs, stolen payment cards, infostealer session logs, and initial corporate network access without revealing their IP addresses or legal identities. Darknet markets and drug vendors still took in $1.7 billion to $2.5 billion in cryptocurrency in 2025, while 48 percent of newly launched markets accepted only Monero and Russian-language dead-drop platforms led by Kraken accounted for more than 90 percent of global volume. The Dark Web article traces the architecture of onion routing and bulletproof infrastructure, the evolution from Silk Road and AlphaBay to post-Hydra and post-Abacus markets, escrow and Monero laundering mechanics, landmark takedowns from Operation Bayonet to Operation RapTor, and the regulated on-ramp and off-ramp choke points where investigators identify operators.
