Scammers Abuse Calendar Invites To Plant Phony Subscription Notices
KnowBe4, March 26,2026
Malwarebytes warns that a phishing campaign is using Google Calendar invites to send phony renewal notices for Malwarebytes subscriptions. The calendar invites contain a phone number that will connect the user with a scammer.
'The amounts in these fake invites are large and attention-grabbing, usually several hundred dollars for multiple years of service,' Malwarebytes says. 'The scammers want you to believe a considerable charge has already gone through so that you react immediately instead of thinking critically.
'The goal is to get you to call, rather than click a link. The calendar description reads like a receipt, but the real call to action is always the same: urging you to call a number immediately to dispute or cancel the charge. Once you call, the scammer can pressure you in real time. They might ask for payment details, convince you to install remote-access software, or manipulate you into sending money.'
