Phishing is seen as a threat that occurs via email, text messages, social media, and other messaging platforms. Since many phishing attacks are delivered by email, email is often the focus of employee awareness training, and employees know to be on their guard when receiving a message that looks potentially suspicious.
However, other platforms and mobile applications are also capable of delivering malicious links or attachments carrying malware. With security efforts focused on email and messaging platforms, cyber threat actors have expanded their techniques to take advantage of platforms where targets are less on their guard, such as the iPhone Calendar app.
The iPhone calendar app is automatically installed on all Apple devices. The purpose of the app is to allow iPhone users to schedule meetings and track other events in a single, convenient place. With support for reminders, the Calendar app helps to ensure that users don’t miss an event that they may have forgotten about or not been directly informed of.
Calendar apps like the one installed on iPhones allow third parties to place events on a person’s calendar. During the pandemic, people became accustomed to receiving and accepting invites for online business meetings, visits with friends, and more. These meetings commonly include a link to a videoconferencing application (Zoom, Google Meet, etc.) that a user can click to join the meeting.
Scammers have begun using the Calendar app in their phishing attacks, inviting iPhone users to meetings or events. These events may contain a malicious link or include an attachment with malicious content. If the user clicks on the link or opens the attachment, it may install malware on their device or attempt to steal login credentials and other sensitive information.
