GUEST OPINION: It is our understanding that any business running versions 7.15 and 7.16 are affected by the outage, but 7.17 seems to be ok.
We are waiting on official advisory from CrowdStrike on these findings but doing our best to help affected customers. It’s a lesson to always update your software, but obviously this is an extreme example. IT security tools are all designed to ensure that companies can continue to operate in the worst-case scenario of a data breach, so to be the root cause of a global IT outage is an unmitigated disaster.
“Crowdstrike support is offering a workaround to customers. It claims users may be able to fix the issue by booting windows in safe mode or in the Windows Recovery Environment and deleting a file named “C-00000291*.sys”.
