This webinar discusses how ICS phishing targets calendar integrations in Microsoft 365 and Google Workspace. It explains how attackers use malicious invites that bypass traditional email security, and how Sublime's platform detects and removes these threats from both email and calendar applications.

iCloud Calendar invites are being exploited to send phishing emails that appear to be legitimate purchase notifications from Apple's email servers, thereby evading spam filters. These emails aim to trick recipients into believing their PayPal accounts have been charged fraudulently, leading them to call a scammer's support number for assistance. The phishing scheme leverages authentic email authentication methods, making the scams appear trustworthy.
