ANDERSEN AIR FORCE BASE, Guam — Officials at a U.S. Air Force base on Guam say they regret any confusion among the general public because of an exercise involving a form of Internet fraud that aims to steal personal information.

The 36th Communications Squadron at Andersen Air Force Base implemented the phishing scam last week as part of the base's Operational Readiness Exercise.

The Air Force said Monday that an internal e-mail purporting to be from "Transformers 3" spoke of a casting opportunity for the movie and asked interested personnel to submit an application with their personal information.

The military says the purpose of the exercise was to measure the effectiveness of information awareness and cybersecurity training efforts.
