"G.I. Joe: The Rise of Cobra" star Channing Tatum is among over 4,000 people who may have had personal information exposed on an unsecured backup drive owned by an unidentified lieutenant colonel.
According to a report by the International Business Times, the information exposed on the unsecured drive, which was able to be accessed via an internet connection, included passport numbers, social security numbers, phone numbers, security clearance levels, and completed SF86 applications for security clearances.
The drive was secured with a password when the leak was discovered by a researcher.

The information contained is considered the "holy grail" by some experts in the field of national security, the website noted. Former government officials told ZDNet that the information could be used for blackmail purposes.
SF86 forms contain information that is used to determine what sort of classified material an individual can have access to. That information includes convictions, financial information, personal or business relationships with foreign nationals, mental health history and similar information. The data breach puts the individuals at risk for identity theft and financial fraud.

The materials on the drive included the spreadsheet that had information on Tatum gathered prior to a six-day tour the actor took in Afghanistan. Other unidentified celebrities also had their contact information compromised.
Information on various probes of American officials was also compromised in the hack. Some of those probes involved allegations of abuse of power. Bank information was also on the compromised disk, as well as years of e-mails.
Both ZDNet and the International Business Times noted that the device was accessible to anyone and searchable, so it may be impossible to determine who has accessed the drive.
