Cyber fraud is digital deception used to steal money, access, or sensitive information. It covers attacks that trick people or systems into approving a payment, revealing credentials, or granting unauthorized access. Common examples include phishing emails, fake invoices, account takeover, impersonation of executives or vendors, and fraudulent support requests.
It matters because fraud often works through normal business channels, so losses can look legitimate until they are hard to reverse. Unlike noisy malware campaigns, cyber fraud may rely on trust, speed, and routine approvals rather than technical compromise alone. Defenses focus on verifying identities, enforcing multi-factor authentication, separating payment duties, using call-back checks for sensitive requests, and monitoring for unusual behavior. In practice, cyber fraud is both a security problem and a process problem: if trust is easy to fake, attackers can turn ordinary workflows into a weapon.
