A recently declassified June 2012 report shows that the Inspector General of the U.S. Intelligence Community is currently reviewing 375 of cases of classified information leaks.
Though most of the cases were considered closed, the IG reopened them about a year ago in order to pinpoint who exactly leaked the information and see where administrative sanctions can be applied. Though some leakers may not be able to be prosecuted, the IG warned that other actions can be taken.
The report, released under the Freedom of Information Act, also shows that five intelligence agencies - the Central Intelligence Agency, Defense Intelligence Agency, National Security Administration, National Geospatial-Intelligence Agency and the Office of the Director of National Intelligence - failed to produce acceptable financial statements that could be audited.
"We found no reasonable assurance that based on the plans we reviewed, any of the five entities would be able to achieve an unqualified opinion on their FY 2015 or FY 2016 financial statement," the IG writes.
In addition, the IG reports that between November 2011 and June 2012, 105 tips have been submitted to its hotline reporting fraud, waste and abuse.
