By | August 30, 2023

This is a small example I put together on how to quickly loop through each user SID in HKEY_USERS and find the value that shows what the wallpaper is set to for each user. This little script is a decent reference to use for finding (And with a little modification, setting) registry value(s) in the… Read More »

Download files from website via Powershell

By | August 11, 2023

A simple method I like to use when I want to quickly run a powershell script to download a file from a webserver.

Scareware is not dead

By | June 19, 2023

An email was forwarded to me that came from a security MSP trying to stir up business with someone at the company I work at.

O365 prompting for an alternative email address

By | October 31, 2022

Recently, O365 started prompting users in my organization during sign-in to add an alternative (Authentication verification) email address.

Idiots using RAID0

By | October 20, 2022

About once a month I read a post somewhere that some poor schmuck is using or wanting to use RAID0 for spanning two drives together or thinking their SSD’s going to get better performance. If you are one of those idiots, we cannot be friends. I cannot deal with that amount of stupidity. RAID0 was… Read More »
