From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Have you ever been researching how Microsoft goes through every "clicked" link posted on Teams chat? (lemmy.ml)

I have seen many scan entries on nginx while sharing links on Teams recently. At first I thought its some type of brute force. Even abuseipdb reports categorize it as web attack.

Some documentation to add to this: https://learn.microsoft.com/en-us/defender-office-365/safe-links-about

Basically its a URL wrapper that provides continuity for the user, so if they dont have a threat intel database entry for the site, they let the user go there. They scan in the background as hemko said above to determine maliciousness.

Worth mentioning they do it for email too if you have it enabled.
