00:00Microsoft has issued an urgent security alert this weekend after discovering attackers
00:04exploited a critical zero-day vulnerability nicknamed Tool Shell, an on-premises SharePoint
00:10server software.
00:12The flaw, which surfaced around July 18th and has been used in active attacks, has already
00:17compromised dozens of servers across government agencies, universities, energy firms, and
00:23telecoms worldwide.
00:25Microsoft has released emergency patches for SharePoint Server 2019 and its subscription
00:30edition, while fixes for Server 2016 are still in progress.
00:35And cloud-based SharePoint Online is unaffected.
00:38Cybersecurity agencies, including the FBI and others, are urging organizations to disconnect
00:44vulnerable servers, noting that patching alone may not remove implanted backdoors.
