Remember the cyber attack on Nasdaq that happened last October?
Now, the country's top electronic intelligence -- aka spying -- agency, the National Security Agency (NSA, is getting involved the investigation, because it turns out that attack "was more severe than first disclosed," Bloomberg reports.
A former counter-intelligence agent said that, "By bringing in the NSA, that means they think they’re either dealing with a state-sponsored attack or it’s an extraordinarily capable criminal organization."
Foreign intelligence agencies are also reportedly helping out the in the probe. Initially investigators thought the hacking intrusion originated in Russia, but that report was wrong.
