Amid global outages affecting major airlines and banks, UAE authorities on Friday issued an alert — urging users of Crowdstrike software to be wary of any software updates.
“We inform you that there is a technical defect in the Crowdstrike software update that may affect the electronic systems of the institutions that use it,” the UAE’s Telecommunications and Digital Government Regulatory Authority said in a post.

Crowdstrike is a US-based cybersecurity technology firm that serves major institutions from around the world.
In Australia, media, banks and telecoms companies suffered outages, which the government said appears to be linked to a Crowdstrike issue.
Crowdstrike ran a recorded phone message on Friday when Reuters contacted its technical support saying it was aware of reports of crashes on Microsoft’s Windows operating system relating to its Falcon sensor, without mentioning Australia.
There was no information to suggest the outage was a cyber security incident, the office of Australia’s National Cyber Security Coordinator Michelle McGuinness said in a post on X.
The outages rippled far and wide, with Spain reporting a “computer incident” at all its airports, while Ryanair, Europe’s largest airline by passenger numbers, warned passengers of potential disruptions which it said would affect “all airlines operating across the network,” though it did not specify the nature of the disruptions.
AWS cloud service provider said in a statement that it was “investigating reports of connectivity issues to Windows EC2 instances and Workspaces within AWS.”
It was not immediately clear whether all reported outages were linked to Crowdstrike problems or there were other issues at play.
