I’ve read a creepy pasta somewhere from this guy’s pov, that somehow discovered a computer at one of the businesses they took over as a contracted IT, think car wash or something, and they’ve ended up discovering a computer in a closet that was networked with other computers in the area to share CSAM and other smut. I forgot how the story ended as it was fairly long, but they were describing the technical non-sophistication of the whole network in great detail. The PCs were basically just networked windows xp workstations or something, without any sort of password protection on them or their shared folders.
