Washington (DC) - The Transportation Security Administration (TSA), often regarded as the cornerstone of the United States' homeland security, has lost a hard drive containing information of over 100,000 people.

The lost data contains only those who are employed by TSA, according to the Associated Press.

"TSA has no evidence that an unauthorized individual is using your personal information, but we bring this incident to your attention so that you can be alert to signs of any possible misuse of your identity," said the organization in a letter to its tens of thousands of workers.

The hard drive contained data from personnel who were employed by TSA as far back as 2002. The administration has teamed up with the FBI to recover the data.
