IT major Microsoft, which faced a global outage on Fridaysaid that the underlying cause for the issue has been fixed, but the residual impact of cybersecurity outages is continuing to affect some Office 365 apps and services.
Even the antivirus firm CrowdStrike said that a fix has been deployed for a bug that caused a global IT outage affecting airports, banks and media across the world.
The recent bug has had a widespread impact, affecting stock exchanges, supermarkets, and flight operations worldwide. Users are encountering the Blue Screen of Death (BSOD) errorleading to unexpected system shutdowns or restarts.
A new Crowdstrike (cybersecurity software firm) update has been cited as the cause of the outage, which has impacted Windows-based desktops and laptops.
Globally, the Microsoft cloud outage led to US airlines cancelling flights, but the tech giant later reportedly said its cloud services outage in the Central US region has been resolved.
In India, major air carriers faced technical issues which led to the delay of flights across the country. The airlines had to check-in passengers manually. Additionally, payments apps, trading platforms, and banking services also took a hit.
Flight delays were reported at several airports, leading to long queues of passengers. The outage affected booking and check-in services for several airlines, including IndiGo, Akasa Airlines, and SpiceJet.
Meanwhile, CrowdStrike also said that the current outage was not a result of any 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,” CrowdStrike CEO George Kurtz posted on X.
Several global news broadcasters also became the victim of the cloud services breakdown. Britain’s Sky News, one of the country’s major television news channels, said they were unable to broadcast.
News agency Associated Press also faced service disruption in news delivery. ABC News in Australia was also unable to broadcast news following the system failure.
HOW TO RESOLVE ISSUE?
Following the outage, the Computer Emergency Response Team (CERT) of the central government issued an advisory explaining how to resolve the issue.
The issues occurred in the latest update of CrowdStrike and the changes have been reverted by the Crowd Strike Team. If hosts are still crashing and unable to stay online to receive the Channel File Changes, the following steps can be used as work around for this issue:
- Boot Windows into Safe Mode or the Windows Recovery Environment
- Navigate to the C:\Windows\System32\drivers\CrowdStrike directory
- Locate the file matching “C-00000291*.sys”, and delete it
- Boot the host normally
