Security vulnerabilities and exploitation of the Zoom conferencing platform (Zoombombing, Link exploits, etc) have been spotlighted in recent news. This write-up is to inform and clarify the position that the University of Alaska holds with Zoom. 

Backstory and Context

Due to the global increase of remote work, and distance education, the web conferencing platform, Zoom, has found its way into the spotlight. In March alone Zoom’s daily user base dramatically increased from 10 million users to 200 million users. Across the nation, many higher education and K12 systems adopted Zoom as the platform to transition from face-to-face classes to online instruction in a very compressed time frame. It is Zoom’s intuitive interface and ability to scale the cloud infrastructure to meet the rapid growth that provides a very inviting and accommodating online environment. 

The University of Alaska chose and adopted Zoom after an extensive and inclusive RFP process across the UA system in 2018. The Zoom implementation replaced the aging video conferencing infrastructure and provides projected savings of ~$100K in FY20 over FY19 costs.

Unfortunately, the ease of use and rapid rise in popularity of Zoom presents opportunities to maliciously exploit the very same features; like screen sharing, standing meeting ID’s, screen sharing,  that enables its ubiquitous popularity; like screen sharing and standing meeting URLs that are reused as a convenience practice. Zoombombing is the notorious exploit making recent headlines that takes advantage of these conveniences and enables malicious actors to intrude a Zoom session and post disruptive content through screen sharing. This type of invasion has caused several educational systems to abandon the platform altogether.
