Password Lessons Learned from Sony Breach

When I was at AOL I spent considerable effort fighting for stronger passwords. There was a “discussion” with marketing on “security versus convenience.” An analysis of the Sony breach by Troy Hunt ( showed a number of things to take note of:

  • Sony had stored over 1M passwords in “plaintext.” The first lesson in “cybersecurity 101” is never do this.
  • 2/3’s of users that had accounts at both Sony and Gawker (another site recently breached) used the same password on both sites. The second lesson is don’t resuse passwords.
