blottsie writes: The NSA and FBI are both expected to investigate the leak of NSA-linked cyberweapons this week by an entity calling itself the Shadow Brokers, experts with knowledge of the process tell the Daily Dot. However, multiple experts say any retaliation by the U.S. will likely remain secret to keep the tactical advantage. Meanwhile, Motherboard reports that some former NSA staffers believe the leak is the work of a "rogue NSA insider." "First, the incident will be investigated by the National Security Agency as it tracks down exactly what went so wrong that top-secret offensive code and exploits ended up stolen and published for the world to see," reports Daily Dot. "An FBI counterintelligence investigation will likely follow, according to experts with knowledge of the process. [...] Following the investigation, the NSA and other entities within the United States government will have to decide on a response." The response will depend on a lot of things, such as whether or not an insider at the NSA is responsible for the breach -- a theory that is backed by a former NSA staffer and other experts. "The process is called an IGL: Intelligence Gain/Loss," reports Daily Dot. "Authorities suss out a pro and con list for various reactions, including directly and publicly blaming another country. [Chris Finan, a former director of cybersecurity legislation in the Obama administration and now CEO of the security firm Manifold Technology, said:] 'Some people think about responding in kind: A U.S. cyberattack. Doing that gives up the asymmetric response advantage you have in cyberspace.' Finan urged authorities to look at all tools, including economic sanctions against individuals, companies, groups, governments, or diplomatic constraints, to send a message through money rather than possibly burning a cyberwar advantage. Exactly if and how the U.S. responds to the Shadow Brokers incident will depend on the source of the attack. Attribution in cyberwar is tricky or even impossible much of the time. It quickly becomes a highly politicized process ripe with anonymous sources and little solid fact."
