Riding on the coattails of the massive rise in popularity in the video conference solution, remote workers new to Zoom need to be wary of where they download the installer.
We’ve written before about the various types of Zoom-related attacks that have sprouted up over the last two months. The latest chapter in this saga involves an actual Zoom installer laden with backdoor malware. Available on malicious third-party sites (and not from Zoom’s official website), these installers are offered up using phishing emails and spam campaigns designed to direct potential victims to these alternative installers.
The compromised installer does deliver an installation of Zoom, but also installs the remote access trojan (RAT) WebMonitor, giving attackers remote access to an infected endpoint via a web browser.

But with so many other types of attacks that seek to trick users into participating, it’s important for users to be continually educated to ensure they don’t make these small understandable mistakes with huge ramifications.
Here's how it works:
