Latest update from Crowdstrike -

Full statement from George Kurtz, the CEO of Crowdstrike:

"Crowdstrike is actively working with customers impacted by a defect found in a single content update for Windows hosts.

"Mac and Linux hosts are not impacted. This is not a security incident or cyberattack.

"The issue has been identified, isolated and a fix has been deployed.

"We refer customers to the support portal for the latest updates and will continue to provide complete and continuous updates on our website.

"We further recommend organisations ensure they’re communicating with Crowdstrike representatives through official channels.

"Our team is fully mobilised to ensure the security and stability of Crowdstrike customers."

CrowdStrike has issued a workaround -


1. Boot Windows into Safe Mode or the Windows Recovery Environment
2. Navigate to the C:\Windows\System32\drivers\CrowdStrike directory
3. Locate the file matching “C-00000291*.sys” and delete it
4. Boot the host normally

CrowdStrike have identified the fault and potential fix. Please refer to your CrowdStrike portal for further information.

Please note Pulsant does not use or support CrowdStrike services and all support is best endeavours.

Initial investigations indicate that following a 3rd party Windows update, clients that use 3rd party service Cloud Strike will be experiencing a significant impact.

Latest update from CrowdStrike - “Our Engineers are actively working to resolve this issue and there is no need to open a support ticket.”

Further updates will follow as they are received.

Pulsant are aware of ongoing issues where initial investigations have indicated a corrupt update on Windows hosted devices and is causing widespread impact.

Pulsant will provide further updates shortly
