Disney hack leads to 1.2TB of Slack communications leaked online
(stackdiary.com)
This is a most excellent place for technology news and articles.
If you're a grey-hat/chaotic-good hacker intent on exposing corporate greed or whatever, with a cache like that, you've got a couple options....either release inmediately, or review the data to minimize collateral damage and release.
If the intent was to help people, and there was no driving force to release immediately, then they should've waited and reviewed the data.
I really worry if this is going to lead to my overly-ambitious infosec group putting the kibash on our unofficial/shadow-IT (fully internal) MatterMost.
Review the data cost your time (which is work time, could be transfer into money).
So, better release it all.
