The Growing Threat of Email Spoofing — and Why SPF/DKIM Still Matter
Email spoofing remains one of the simplest yet most effective social engineering tactics. Attackers impersonate trusted senders to deceive employees and clients, often using nearly identical domains or unprotected mail servers. Without authentication records, these fake messages slip through filters and cause serious financial damage.
SPF, DKIM, and DMARC remain the core standards that verify legitimate senders and block impersonation attempts. Unfortunately, many businesses still have incomplete or outdated records, leaving gaps for attackers to exploit.
