The right message, sent by the wrong person

Corporate scams seldom rely solely on a technical failure. They exploit context, urgency, and trust relationships to make a message appear legitimate. When identity and channel cease to be reliable signals, the organization must combine technical controls with clear verification and escalation processes.

How the attack undermines trust

The selected evidence points to complementary controls to mitigate this risk. ENISA launched an educational cybersecurity resource platform. A report on cybersecurity and EU network resilience was published in February 2024. The report identified threats such as ransomware and physical attacks as significant risks. Together, they show that identity protection, vulnerability remediation, and team preparedness need to function as layers, because no single measure eliminates the possibility of manipulation.[1]

The problem doesn’t end in the inbox

The impact appears when a false request enters a genuine process: payment, document sharing, account recovery, or credential change. Therefore, communication governance requires defined responsibilities, a decision trail, and a second confirmation channel for sensitive requests. Operational speed cannot take away an employee's ability to halt a suspicious interaction.

Where defense often fails

Documented risks include: The risk of ransomware attacks on communication infrastructures. Vulnerabilities in supply chains can be exploited. Physical sabotage to digital infrastructures poses a high risk. The point of concern is the combination of technical fragility and human pressure. A protected account decreases part of the exposure; a confirmation process reduces another. The absence of either of these layers increases the chance of a fraudulent message prompting a legitimate action.[1]

Trust needs verification

Corporate communication will continue to rely on speed and collaboration. The goal is not to block these characteristics, but to prevent apparent identity from being treated as sufficient proof. More resilient organizations make verification simple, visible, and compatible with everyday work.

Por que isso importa?

A fraudulent message can trigger legitimate processes before the organization realizes the trust breach. Communication, identity, and response controls need to operate together.

Recomendações práticas

  • Adopt multi-factor authentication on critical accounts; establish out-of-channel confirmation for financial requests or access changes; facilitate reporting of suspicious messages; and assign responsibility for response and communication. These are editorial recommendations derived from the analyzed risk and should be adapted to the context and controls of each organization.
