Microsoft Windows computers were faced with a grave situation yesterday. A faulty cybersecurity update caused a global outage, impacting thousands of PCs and servers, with the screens experiencing a Blue Screen of Death issue (BSOD). The outage has affected various sectors worldwide, including banks, airlines, businesses, and supermarkets, and IT admins worldwide are trying to find a fix. Although Crowdstrike and Microsoft have provided a standard fix, it could take a while for the issue to be fully resolved.
A massive global IT outage disrupted the operations of many institutions due to a cybersecurity update gone horribly wrong, a fix is released
Crowdstrike is a cybersecurity company that lends its services to many big businesses around the world. It was recently blamed for a faulty cybersecurity update that crashed thousands of Windows PCs and led to massive work disruptions worldwide. This happened early Friday morning after the company made a sensor configuration update as part of its protection mechanism for one of its cloud-based platforms, Falcon.
The healthcare sector, airline industry, banking system, and other major industries were faced with the global outage where their PCs entered a Blue Screen of Death (BSOD) error and stopped working amidst the error. Although Crowdstrike claimed to have fixed the root of where the problem was stemming from, it can take a while for the issue to be completely eradicated.
Crowdstrike provided a workaround, as reported by The Verge, that can be used for the time being to recover the PC and put the system into Safe Mode. Here are the steps provided for IT admins of the companies to put Windows into Safe Mode:
Step 1: Boot Windows into Safe Mode
Step 2: Navigate C:\Windows\System32\drivers\CrowdStrike directory
Step 3: Locate the "C-00000291*sys" file and then delete it
Step4: Power on the Host
These steps help Windows start in Safe Mode and prevent third-party drivers such as Crowdstrike from loading. Microsoft also presented a workaround suggested by many users and used by IT admins in general. It involves rebooting the PC around 15 times. It has been said to have worked for many individuals. Microsoft shared this fix on its Azure outage support page.
Sometimes, it takes the servers time to respond to reboots due to the number of requests poured in from all the hammered machines. While some systems could be recovered with these fixes, ensuring every customer's Windows is fully recovered may take a while. Crowdstrike took responsibility for the faulty update and the damage caused, but users are still confused about the extent of the outage by merely a faulty update.
