We are seeing a growing cybersecurity threat impacting small and mid sized businesses: calendar invite phishing attacks.
Instead of relying on traditional phishing emails, cybercriminals are using calendar invitations to bypass spam filters and trick users into clicking malicious links. These invites often appear legitimate and may include fake meeting requests from known contacts or vendors, urgent or time sensitive subject lines, and links to fraudulent login pages designed to steal credentials.
Because these invitations are delivered through your calendar system, they can be harder to spot and are often trusted by users. Calendar invites may automatically appear on your schedule, even if you do not accept them. Once attackers steal credentials, they can use them to compromise accounts, access sensitive data, or commit financial fraud.
SkyViewTek helps reduce the risk of calendar invite phishing through a layered cybersecurity approach, including:
- Advanced Microsoft 365 email and anti phishing security policies
- Suspicious link detection and Safe Links style protections
- MFA and Conditional Access policies to protect user accounts
- Monitoring for unusual login activity and account compromise attempts
- Security awareness training focused on suspicious meeting invites
- Mailbox and calendar security configuration reviews
Here are a few steps you and your team can take right now:
- Be cautious of unexpected or unusual meeting invites
- Do not click links unless you can verify the sender and the purpose of the meeting
- Report suspicious invites to your IT team immediately
If you have any questions or would like to review your current security setup, we are here to help.
