Porn in emails
My first job after uni, my mates had my work email address and I often found myself on mass mailings of porn one friend was sacked from his work and the mass mailings soon stopped.
Nowadays I no longer give my work email to friends, luckily I no longer receive any porn by email to any of my personal accounts.
It’s amazing how many places permit ssh to anywhere.
Properly locked down comms, with no default routes to the net & passing all user offsite traffic through a proxy is the way to go but more and more places are turning to the cloud and needing quad 0 out :(
