Whaling attacks are a specialized form of spear phishing targeting high-level executives, exploiting their access to sensitive information and systems to cause significant financial and operational damage. These attacks use personal details to craft convincing messages that navigate authentication weaknesses, often stealing executive credentials through spoofed emails, fake login pages, and public data exploitation. Credential theft is facilitated by weak or reused passwords, making passwordless authentication a vital defense. Phishing-resistant methods like passkeys are recommended to protect against these threats, as they render intercepted login attempts useless. Organizations are encouraged to implement additional measures such as security training, role-based access controls, and rigorous email filtering to bolster their defenses. Descope offers a solution with its phishing-resistant, passwordless authentication platform, aiming to secure executive logins and prevent whaling attacks by deploying modern methods like passkeys.
