NSA contractor arrest highlights challenge of insider threat
WASHINGTON — The arrest of a former National Security Agency contractor for allegedly stealing classified information represents the second known case since 2013 of a government contractor being publicly accused of removing secret data from the intelligence agency.
The latest case comes as the NSA has worked to reform security after the Edward Snowden disclosures, especially with regard to insider threats.
Harold Thomas Martin III, 51, of Glen Burnie, Maryland, was arrested by the FBI in August, after federal prosecutors say he illegally removed highly classified information and stored the material in his home and car. A defence attorney said Martin did not intend to betray his country.
The arrest was not made public until Wednesday, when the Justice Department unsealed a criminal complaint that accused Martin of having been in possession of top-secret information that could cause “exceptionally grave danger” to national security if disclosed.
