Data Acquisition uptime Lab

Hey, Leo Dregier here. I want to show you a quick command uptime simply because most people know, don’t know that it exists. It’s very simple. Just type uptime on any UNIX terminal and it’ll give you the uptime of, of the computer, the average load, the number of users, uh, timestamp information; uh, very, very simple, very, very basic. Not much you can really do with this. If you can do a man uptime, okay, it’ll simply tell you how long the system has been up and running. It is a very, very simple utility, um, but it quickly answers the question of how long has the system been up? In the world of hacking, you’re looking for this information because if you find something that’s been up for, let’s say, two years, clearly it hasn’t been patched. Forensically, if somebody been, you know, rebooting it, if they say that they’re computer has been on, realistically, how long was it on? Okay, so you can use it to see, uh, and verify certain pieces, information in the forensics and the hacking world. Thank you for watching. My name is Leo Dregier.
