What would you do if the applications that have become a core part of your operations turned into digital attack vectors? Learn how cybercriminals can deliver macOS malware through attacker-controlled public iCloud calendars and cloud storage.<\/span><\/p>\n

A Devious Way To Bypass Traditional Defenses<\/b><\/p>\n

Cybersecurity has come a long way, and directly infecting systems with malicious files is fairly difficult. For this type of attack to work, a threat actor needs to successfully trick the victim into downloading and running the deceptive program on their device.<\/span><\/p>\n

Even if they’re successful, up-to-date antivirus and firewall solutions would quickly flag malware before it can do lasting damage. Criminals would also have to repeat this tedious process each time they want to deploy another type of malware.<\/span><\/p>\n

Unfortunately, several workarounds exist, such as malware loaders and DLL sideloading. This two-phase approach (initial infection and deployment of malicious payloads) gives threat actors more flexibility and lowers detection rates.<\/span><\/p>\n

Why iCloud Calendar?<\/b><\/p>\n

Modern defenses monitor incoming and outgoing traffic across applications, so they can still detect when a loader tries to deploy Mac malware. The problem only comes when criminals manage to hide this traffic.<\/span><\/p>\n

Here’s how they do it:<\/span><\/p>\n
