Calendar Invite Scams Surge Among Business Users
Tap title to read story
Scammers increasingly target professionals by sending forged calendar invitations that automatically populate users’ schedules. These invites lure recipients to phishing sites or fake calls, exploiting the trust built into calendar integrations.
The tactic is especially effective in corporate environments where meeting invites are routine, making the deception harder to spot. Security experts advise disabling automatic event additions from email and reviewing calendar permissions.
Companies should educate staff on recognizing suspicious invites and report them promptly. By tightening calendar settings and raising awareness, businesses can reduce the risk of credential theft and protect sensitive information.
