The CrowdStrike Bootloop Incident
Will this affect me?
Most people won’t be affected by this on personal machines, however your work windows machines maybe. It won’t affect people using Mac or Linux.
What caused this?
Not much has come to light so far but it seems a bad update to CrowdStrike’s Kernel Level Driver (referred to KLD from here out) had a broken update published where the every byte of the driver’s .sys file was replaced with the hex number00.
Most importantly this was not Microsoft’s fault and was not a part of a windows update.
CrowdStrike’s KLD “Falkon” protects:
- 298 fortune 500 companies
- 538 fortune 1000 companies
- 43 US States
Matter of fact, people in the US state of Alaska, Ohio and others were unable to call 911 as their systems ran Windows, and had CrowdStrike’s KLD “Falkon” installed.
What else was affected:
- Windows 365 Cloud PCs, apps and services
- Delta Airlines, United Airlines and American Airline
- German hospitals
- Live tv broadcasts in the UK, Australia and other countries were affected
- ABC Radio being unable to play music
- Airport check-in systems
- Banks and payment systems
- Supermarkets, petrol stations, etc
- Government departments
- Universities
- Law firms
- Mines
- And many more companies
ABC Australia continued to broadcast, however without teleprompters or on-screen graphics.
