Overview
In 2008, the U.S. Department of Defense suffered a significant compromise of its classified military computer networks. It began when an infected flash drive was inserted into a U.S. military laptop at a base in the Middle East. This previously classified incident was the most significant breach of U.S. military computers ever, and served as an important wake-up call.
