I am not sure whether I should laugh or cry... This randomises your MAC and hostname and then prevents outgoing connections. Unless you think the NSA is running nmap on every public WiFi it does not even do what is printed on the tin. I am trying to imagine what threat model this is trying to address and why this particular set of options was chosen, as I can't see them being particularly effective and the general annoyances of step three in the process will tend to have this script nuked by the user within 72 hours.
This may be a bit of a tangent; but if you wish for them to not watch your traffic (as much), encapsulate all of your data in pictures. Oh, you think I am about to suggest Stego? No way, super obvious!
You will need to get a volunteer or volunteers to help you create a few thousand variations of tubgirl with different facial expressions and different ingredients. There might be a couple folks that will watch those pictures specifically, but most of them prefer the breast and penis pics that you are all sexting back and forth. It won't stop all the snooping, but it will reduce the number of people snooping dramatically.
Each facial expression represents a different utf-8 or utf-16 character. You are going to need to make a LOT of pictures unless your messages are really simple. Each different color fluid could represent different voice inflections or perhaps a different character-set-of-the-day.
If I could get a volunteer, we could write the first "Hello World".
NSA be gone? good luck with that.
They define themselves as a "capabilities oriented organization", and that basically translates into discovering and hiding backdoors into everything.
The trouble with a completely random hostname (or username---mine is pc2g4d after all) is that they're used by few enough people, and when sufficiently long are easily distinguished from non-random strings, that maybe they can actually reduce anonymity.
For example, if you see the following pool of usernames:
alice
bob
charlie
W2zwAe3W9oVkRK9aSXWnTsxLj
And then in another context you see another pool of identifiers:
doug
erin
filipa
iA4PrG7jtp6hmNQNVDCqk36C
Which of these don't belong? It seems at least possible that the random identifiers were generated by the same person, or at least the same type of person.
The fact that an identifier provides no information is itself information. I wouldn't be surprised if this could be a useful signal for linking accounts that are meant to remain totally unlinked.
So totally random MAC addresses or hostnames could just cause you to stand out.
Considering that tracking also occurs based on browser cookies or even more indirect methods, seems this tool's primary effectiveness would just be deterring profiling by public wifi AP operators.
