Google Calendar Is a Potential Tool for Hackers to Control Malware

Hackers could potentially use Google Calendar to secretly send commands to malware, according to Google’s warning about its own service. The technique, which involves the malware periodically connecting to Google Calendar to retrieve and execute the commands, could be used to mask hacker activity as legitimate traffic, making it harder for antivirus programs and cybersecurity professionals to detect it. Currently, no such activity has been observed but Google is urging businesses to monitor their networks for unusual activity.
