Re: Lots of revenge hacks recently...
$100K is NOT a big loss at all! If you add up the time taken by everyone involved along the way from initially noticing something is wrong, troubleshooting until the issue is found (for which they hired an outside firm) and getting everything up and running again. Don't forget to add the time wasted by accountants who couldn't do year end closing - and maybe had overtime once it was fixed and they were able to work, potential state/federal fines if certain deadlines for reporting are missed, plus all the time taken by various managers for constant status meetings.
$100K looks like a massive lowball estimate of what they could have calculated.
Speaking of constant status meetings, I was on one for about four hours yesterday that had at its peak 50 people on the Skype call. That's easily running over $1000/minute!
