Google, SpaceX, and even NASA, recently banning employee use of Zoom as they shift to work-from-home workforces in response to COVID-19 have shined a spotlight on the widely popular video conferencing tool’s security flaws.

Guloader is a downloader that has been widely used from December 2019. Several security researchers have identified the downloader in the wild, signifying that it has quickly gained popularity among threat actors.

This isn’t really a new method of enticing people to download and run their malware; threat actors have always used disasters as a way to deliver their payloads.
