Your calendar might be telling you to attend a meeting you never scheduled, and that appointment could have a criminal agenda. Calendar invite scams surged 1,216% from July to August 2026, according to cybersecurity firm Sublime Security. The attackers exploit something most people rarely question: an ordinary invitation that appears alongside legitimate appointments.
The scam doesn’t necessarily begin with a suspicious email demanding money. Instead, a fake meeting can slip onto your schedule, complete with an official-looking subject line and a link that seems perfectly reasonable. You might spot it while checking tomorrow’s appointments, long after the original message has disappeared into your inbox clutter. That small detail helps explain why these scams deserve attention, even from people who already know how to spot sketchy emails.
