[Crypto-chi] [ssh] Cryptoparty at SSH on December 5 from 2-4pm

[Nicholas Rutzen]

I am having an issue related to cryptography and general information
security; I figure this is a good forum to seek help.

Every day I eat lunch at the same place, I use the Google Starbucks wifi
and read or watch educational videos, nothing particularly sensitive.  In
the past 2 months, there have been 3 man in the middle attacks on this
network that I have observed.  It starts with the wifi getting slower and
slower until it is unuseable, then suddenly all of the ssl certs are
invalid and google.com reroutes to Google Cameroun or whatever odd domain
that kinda looks like Google but isnt.

They have been getting progressively better too, with the first one failing
all certs, the second redirecting to odd domains and downloading a proxy
script on connection, and the third I simply disconnected right away cause
my computer is starting to repeatedly ask me for my icloud password (for my
gmail account, I have never used icloud).
The strange behaviour only started after the second attack and script
download.  How do I stop this person?  I can route my traffic through vpns
and encrypt but I doubt others in the shop even realize what is happening.
Any suggestions?
