What You Can Learn from the Ashley Madison Hack
You might have heard that the adult cheating site Ashley Madison was hacked recently and that the initial thought from Ashley Madison was that the data compromised did not contain real data. Today there were reports that the data stolen (all 10 compressed gigs of it) indeed contained real data on actual users and internal documents according to experts.
What you can learn from all this: Not to sling mud at Ashley Madison, but this demonstrates a key principle within the security industry and that is if you get hacked, assume everything is compromised, look for evidence to suggest otherwise and work your way back. Not the other way around assuming that the compromise was limited or not significant.
