Bank account laundering is a form of money laundering where criminals use legitimate bank accounts - often belonging to unsuspecting individuals or businesses - to move, conceal, or disguise illicit funds. This process may involve transferring illegal money through multiple accounts to obscure its origin and make it appear legitimate. Criminals may gain access to these accounts through social engineering, phishing, or by recruiting individuals (sometimes called 'money mules') to knowingly or unknowingly participate. Bank account laundering poses significant challenges for financial institutions and law enforcement, as it exploits trusted banking systems and can be difficult to detect without advanced monitoring and analysis. It is commonly associated with fraud, cybercrime, and organized crime activities.
