In a note to investors on Monday, Wedbush Securities' Daniel Ives wrote that there are 'some lingering issues into this week so far out of the gates.

' Ives, managing director and senior equity research analyst at Wedbush, stated, 'We are seeing IT outage issues still persist in spots around the globe from the CrowdStrike IT outage heard around the world on Friday.

' He added that this is not good news for CrowdStrike CEO George Kurtz and his team, as many businesses are still struggling to return to normal operations despite fixes and mediations released throughout the weekend.

CrowdStrike and Microsoft have been working to expedite the recovery process for the millions of affected Windows devices.

Over the weekend, CrowdStrike posted a 'Remediation and Guidance Hub' to assist with recovering from the outage, providing technical details and guidance for IT administrators.

Meanwhile, Microsoft released a free tool on Sunday to help clients recover from the outage, enabling administrators to more quickly recover Windows devices using a more automated approach.

Late on Friday evening, CrowdStrike identified a 'logic error' as the cause of the Microsoft outage.

The programming error was triggered by a sensor configuration update to Falcon.

For an unknown reason, this configuration update caused a logic error resulting in a system crash and blue screen (BSOD) on impacted systems, the company said.
