Security firm Sublime has reported a surge in phishing attacks delivered via calendar invitations (ICS files) rather than traditional email, warning that such invites can bypass spam filters even when the accompanying email is blocked. The scams typically mimic legitimate meeting invites or payment notices, directing victims to fake login pages or malware disguised as Microsoft, Google, or PayPal services. Sublime says ICS phishing incidents rose roughly 33,000% between May and September, with attacks doubling or tripling month over month.
