Circular financing is a funding pattern in which money moves through a loop of related parties, returning to the origin or to a controlled beneficiary after one or more transfers. The loop can involve shell companies, mule accounts, distributors, vendors, or prepaid contracts. In finance, it can make demand, revenue, or liquidity look stronger than it really is.
In cyber security, circular financing matters because criminals use it to launder stolen funds, conceal ransomware proceeds, inflate fake sales, or support fraud schemes that depend on fabricated business activity. Defenders look for repeated counterparties, rapid in-and-out transfers, matching invoice amounts, unusual prepayments, and transaction graphs that show funds cycling back. Analytically, these patterns can signal obfuscation, even when each individual payment seems legitimate on its own.
