Payment service providers serve as licensed principals whose agent networks can be exploited when:

  • Criminals leverage white-labeled or aggregator-driven platforms that mask the identity of sub-agents.
  • Only the aggregator is visible to receiving institutions, obscuring the sub-agent’s role.
  • Complex principal-agent relationships dilute oversight and weaken AML controls.
  • Illicit flows blend in with legitimate services under the provider’s authorized framework.

Automated scripts plug into PSP APIs/gateways to trigger high-volume, cross-border micro-payments that stay below single-transaction thresholds, exploiting PSPs’ speed and jurisdictional reach to fragment the audit trail and hide ultimate beneficiaries.

Payment service providers are unwittingly exploited in the chargeback process by:

  • Offering legitimate dispute resolution channels that criminals manipulate with fabricated justifications.
  • Processing refunds that reintroduce illicit funds into regular financial flows, complicating link analysis and tracing efforts.

These providers process online payments for counterfeit pharmaceutical sales, often relying on limited product information or mislabeled transactions. Criminals exploit:

  • Rapid payment settlement to move illicit proceeds quickly.
  • General-purpose or unverified merchant accounts, concealing the true nature of transactions from financial countermeasures.

Payment service providers enable cross-border transactions on behalf of diverse clients and can be misused when:

  • Criminals exploit partial or delayed integration of standardized data fields, reducing transparency on originators and beneficiaries.
  • Multiple rapid transfers across providers and jurisdictions obscure the true flow of illicit proceeds.

Criminals exploit these providers' online transaction services to channel illicit funds under the guise of legitimate donations by:

  • Routing multiple small contributions from fake or co-opted donor accounts, layering the origin of funds to appear philanthropic.
  • Exploiting variable or minimal KYC protocols, hindering real-time detection of account abuses.

This principally occurs without the providers' knowledge, posing significant challenges for financial institutions to uncover suspicious flows and trace ultimate beneficiaries.

PSPs may be exploited as cash-out or layering points when cryptojacked assets are routed through their platforms; failure to detect unusual flows or address anonymity features can aid laundering.

Payment service providers may unwittingly process criminal transactions by:

  • Rapidly approving or settling e-commerce payments and refunds with limited oversight.
  • Handling an array of small or micro-transactions that collectively launder significant illicit funds.

Insufficient verification of merchant legitimacy and transactional patterns reduces the effectiveness of AML controls.

Criminals exploit third-party payment processing to:

  • Issue inflated or fictitious payroll disbursements through batch payment systems.
  • Reduce direct oversight of each payee’s legitimacy or wage amount, enabling the integration of illicit funds as ordinary salary payments.

Payment service providers (the aggregator or principal) offer the licensed framework under which sub-agents transact. They may:

  • Fail to maintain stringent oversight over sub-agents, allowing criminals to exploit these partner outlets.
  • Obscure the actual sender or beneficiary in transaction records, as only the provider’s name often appears, limiting the visibility of sub-agent activities.

Criminals exploit PSPs offering e-wallets or prepaid cards to deposit and withdraw funds labeled as gambling earnings.

  • Minimal customer verification or transaction monitoring allows swift cross-border transfers that camouflage the illicit origin of proceeds.
  • Financial institutions struggle to link layered transactions back to criminal beneficiaries when disguised as routine gambling payments.

Payment service providers handle deposit and withdrawal channels that criminals exploit by:

  • Accepting transactions sourced from stolen or compromised payment credentials, disguising them as legitimate wagers.
  • Overlooking rapid or irregular deposit and withdrawal patterns due to insufficient monitoring.

This weak oversight allows illicit proceeds to flow through gambling sites largely unchecked, complicating financial institutions’ efforts to detect suspicious activity.

Payment service providers, such as electronic billers or aggregator platforms, can be manipulated to process third-party payments:

  • Criminals input incomplete or inaccurate payer details, obscuring the true account holder.
  • Financial institutions see fragmented payer information, making suspicious activity detection more difficult.

Payment service providers connect merchants to payment networks and handle transaction settlements. Criminals exploit these providers by:

  • Using aggregator or sub-merchant setups to combine multiple merchants’ payments into single accounts.
  • Mixing unlawful transactions with legitimate sales volumes, making it difficult for financial institutions to detect anomalies.

This aggregation model conceals the ultimate source of funds within routine settlement flows.

Payment service providers may knowingly or unknowingly offer virtual IBAN references, allowing clients to generate multiple IBAN-like identifiers from one real account. In many cases, lighter KYC or reduced oversight at the reference level enables criminals to conceal ultimate beneficiaries and obscure transaction flows, challenging financial institutions’ due diligence.
