Funds received and immediately transferred onward with minimal dwell time, suggesting the account is being used as a pass-through to layer illicit proceeds and obscure audit trails.
Structuring / Threshold Avoidance
Deliberate splitting of transactions to remain below reporting thresholds or monitoring triggers. Commonly associated with layering proceeds of crime or avoiding CTR filings.
Behavioural Change Indicators
Sudden or unexplained changes in a customer's transaction behaviour relative to their established profile, such as new geographies, increased volumes, or different payment types, potentially indicating account takeover or use for laundering.
Mule Account Activity
