Massive Hack Hits Microsoft SharePoint Servers | Tech Field Day News Rundown: July 23, 2025

Hackers have used a serious, previously unknown flaw in Microsoft’s SharePoint server software to launch a major global cyberattack. The attack has hit U.S. government agencies, universities, energy companies, and more, but only affects on-site servers—not cloud services. Stolen data and encryption keys could let hackers keep access even after systems are patched. Microsoft has released a fix for some versions, but many servers are still at risk. Authorities in the U.S., Canada, and Australia are investigating, with over 50 organizations confirmed as affected so far. The attackers’ identity and goals are still unknown. This and more on the Tech Field Day News Rundown with Tom Hollingsworth and Alastair Cooke.
