"Given the technology that would be required to retrieve the data, Hummingbird believes that any misuse of the data is extremely unlikely," the company said. The statement added that the company filed a lost property report with the police after having "exhausted every possibility to recover the stolen equipment."

TG has set up a call center at (800) 530-0626 to provide information to affected customers. The company also plans to start sending letters to all of the affected individuals in the next few weeks Boyer said.
