The 15 Worst Data Breaches of the 21st Century

June 20, 2017

It's not exactly an honor roll that CSO has published, but it sure makes for interesting reading. Hat tip to Dave Ries for sharing the list. As a caveat, the list is based not necessarily on the number of records compromised, but on how much risk or damage the breach caused for companies, insurers and users or account holders. In some cases, passwords and other information were well protected by encryption, so a password reset eliminated the bulk of the risk.

Here are the unlucky victims (the story includes the dates, the number of records compromised as well as other details and is worth reading).

  1. Yahoo
  2. Adult Friend Finder
  3. eBay
  4. Heartland Payment Systems
  5. Target Stores
  6. TJX Companies, Inc.
  7. JP Morgan Chase
  8. US Office of Personnel Management (OPM)
  9. Sony's PlayStation Network
  10. Anthem
  11. RSA Security
  12. Stuxnet
  13. VeriSign
  14. Home Depot
  15. Adobe

Not all publicity is good publicity. A lot of reputational damage is unavoidable collateral to a data breach.
