Security Incidents DE · Medium sophistication
Last updated November 3, 2026

A Banca Ifis manager received payment-request emails from someone posing as a colleague and approved transfers totaling about €23.8 million. The incident is a business email compromise (BEC) case: the attacker used a trusted internal identity and a routine payment workflow rather than a technical exploit.

Key findings

  • In May 2026, a Banca Ifis manager received payment-request emails from a person claiming to be a colleague.
  • The manager authorized payments totaling approximately €23.8 million.
  • The funds were routed through Spain as well as Singapore, Hong Kong, and Bahrain.
  • Authorities reportedly seized €20 million in Barcelona.

Who’s being targeted

  • Commonly targeted roles: Finance managers, Treasury teams, Accounts payable staff, Payment approvers, Banking operations staff, Executives with payment authority.
  • Affected industries: Banking, Financial services.
  • Attack channels: email.
  • Impersonated: A Banca Ifis colleague.

Awareness takeaways

  • Independently verify unusual or high-value payment requests, even when they appear to come from a colleague. Use a known phone number or an established internal approval channel, not contact details in the message.
  • Treat any emailed request to approve a transfer as high risk until it has passed the organization’s out-of-band verification and dual-approval process.
  • Escalate suspected payment fraud immediately; rapid reporting can improve the chance that transferred funds are frozen or recovered.

Red flags to watch for

  • The request relies on an unverified colleague identity.
  • The email asks the recipient to authorize a high-value payment.
  • The recipient is asked to rely on email alone for payment approval.

Funds went through Spain, Singapore, Hong Kong, and Bahrain. That’s business email compromise: a familiar name isn’t proof. Before approving a payment, call your colleague on a number you already know.
