Manipulated Supplier Bank Details: Cyber Fraud and Phishing Risks in Payment Processes Are Increasing

Payment diversion, BEC, and phishing attacks threaten corporate payment processes

Frankfurt am Main, April 17, 2026 – Cyberattacks on corporate payment processes are on the rise. In particular, phishingBusiness Email Compromise (BEC), and so-called payment diversion are increasingly causing payments to be redirected to fraudulent accounts. 

As invoice processing becomes more digital and cloud-based platforms are widely adopted, new attack surfaces are emerging—especially in accounts payable and procure-to-pay processes. 

 

Payment Diversion: How Attackers Manipulate Payment Flows 

Rather than creating fake invoices, cybercriminals are increasingly targeting existing supplier bank details to redirect payment flows. 

Common attack scenarios include: 

  • Manipulating invoices during electronic transmission  
  • Gaining access to email communication between companies and suppliers  
  • Phishing attacks targeting accounts payable teams  
  • Compromising cloud-based procurement or supplier platforms  

The result: payments are unknowingly sent to accounts controlled by fraudsters. 

Once a payment has been executed—whether for invoices or recurring transactions—it is often difficult or impossible to recover. 

 

Risks for Companies: Financial Losses, Operational Impact, and Reputational Damage 

Manipulated bank details not only lead to direct financial losses but also have significant operational consequences: 

  • Increased manual effort in accounts payable  
  • Delays in supplier payments  
  • Disrupted supplier relationships  
  • Reputational risks  
  • Higher exposure to ongoing cyber fraud  

The risk is particularly high in centralized payment environments and high-volume payment scenarios. 

 

Prevention: Validate Bank Details Early in the Payment Process 

To reduce payment fraud and phishing risks, companies must strengthen their internal controls. 

A key measure is the early validation of supplier bank details before payments are executed. 

Best practices include: 

  • Verifying changes to supplier master data  
  • Matching IBAN and account holder before payment  
  • Integrating validation checks into payment workflows  
  • Reducing manual controls through automation
