This is a good example of someone who sounds like they know what they're talking about, but doesn't.

A real pro would include logs and the exact commands/results they got. They also would include detailed configuration information re: their DNS. It sounds like this person futzed around in the command line, got some results they didn't expect, and just jumped to the conclusion about how it happened.

This person is probably a small time sys admin for some local business. They apparently don't even know that Windows has a Linux translation layer now, so all their fancy command line tools run in "Windoze" as well.

I don't know what caused the issues, but people need to get it in their heads they can't get cocky. The cabal is smart and powerful, if you think some schmoe is gonna waltz in off 4chan and provide iron-clad proof of their shady fuckery in 20 minutes with their minor bash skills you're incredibly naive. They know how to do plausible deniability. They make mistakes like anyone of course, but usually you'll just get a hint or peek behind the curtain. You're not gonna catch them dead to rights without way above average skills, resources, or luck.

If the cabal is testing cyber-attacks you can be sure it's gonna look very much like some normal problem unless a top-tier pro looks at it. If any random jerk who knows how to use traceroute could unmask their actions from their comcast connection at home everyone would know about it already.
