Hackers have reportedly found a way to use the Google Calendar as command & control (C2) infrastructure which could create quite a few headaches in the cybersecurity community.
Do I understand correctly that this is not at all an exploit for Google Calendar itself, but just uses the Calendar share functionality to communicate to already infected hosts? That can be applied to pretty much any service with publicly accessible of sharable data though...
I'd call this website out for clickbait but it seems like every tech news website is copy-pasting this same fearmongering article.
I'm actually surprised that this wasn't seen before. It's a domain that can't be blocked in lots of companies, and frequent requests to it won't raise any flags in any company that uses Google Workspace.
Yep, this. A couple years ago, Google Drive sharing was used in a loosely similar way to deliver malware, and Google had to build some new controls. I'm surprised it took the baddies this long to exploit GCal.
I don't know, I'm really interested in all these internet services that are 100% safe from hackers. Sounds like very useful information that should be shared around.
They are encoding commands in calendar events there is not a vulnerability in Google calendar. After your device is compromised its commanded to subscribe to a calendar. Those events have commands. Since checking your calendar is a normal event unlike connecting to a nefarious server it becomes more difficult to discover.
Is it? Everything is in their cloud. You’d think since they have all the data they might check it for malicious activity. I guess that’s not much of a priority for them because it’s hard to tell what’s malicious and what’s “Google”
