Money refers to any medium of exchange that is widely accepted in transactions for goods, services, or repayment of debts. In cybersecurity and financial crime contexts, 'money' often relates to the proceeds of illegal activities that criminals attempt to disguise through money laundering. This process involves moving illicit funds through complex financial systems or shell companies to make them appear legitimate and difficult to trace. Understanding how money moves and is concealed is crucial for detecting and preventing financial crimes online.
