While the Hannaford Breach which resulted in 4.2 stolen credit cards and 1800 known fraud cases may not be a web hack, a Computer World article mentioned that the company's web site was off line following the breach. Even if the breach itself was not a result of web site issues, such issues where probably found in the security review to follow the Breach making the incident a worthy addition to WHID.
