Department of Energy loses 1500 employee records
According to a recent article, an unclassified computer belonging to the DOE was hacked in September of 2005, and had a file containing names, social security numbers, and security clearances for 1500 employees stolen. Frighteningly, senior management was only made aware of this two days ago, or nearly nine months after the fact.
What separates this incident from most data disclosures is that the article makes this out to be a TARGETED theft of data, rather than randomly stealing hardware that happens to contain sensitive data. In this case, the data was the target.
