Fun fact: It's impossible for the NSA/CIA to classify their actual malware and exploits, since releasing classified materials (e.g. deploy a virus) is strictly forbidden. The only way of concealment is obfuscation.
Also, the secret service cannot claim copyright under the Constitution, since they are official works by the government.
Thus, the U.S. secret service is one of the largest contributor of infosec-related public-domain free software to the rest of the world, directly funded by the taxpayers.
