Microsoft 365 Users Report Issues Accessing Teams: Could Recent 'Anonymous Sudan' Hack Be The Cause?

Microsoft Corp MSFT tweeted that it investigated an issue where some U.S. users could not access Microsoft Teams using web browsers.

Users reported problems with Microsoft 365 at 8:30 am ET, as per Downdetector.

Around 67% of the users faced issues accessing Outlook, 24% with Outlook, and 10% faced login issues.

A separate report indicated that "Anonymous Sudan," a hacktivist group, has been causing outages at Microsoft for months, with previous attacks also in Israel, Sweden, and other countries. Some cybersecurity researchers associate this group with Russia.

The hacking activities caused temporary outages in some of Microsoft's critical services like Outlook, Teams, and OneDrive.

On Tuesday, Microsoft fixed an Outlook for the web access issue affecting its customers in North America.

Price Action: MSFT shares traded higher by 0.47% at $336.15 on the last check Wednesday.
