NSA Declares ‘Anonymous’ a Threat to National Security

In Anonymous’s move away from denial of service attacks and toward real-world interactions –  such as recent threats against the Los Zetas Cartel –  the hacktivists have attracted the attention of the National Security Agency. In private meetings at the White House, NSA director General Keith Alexander warned that in a year or two the group could attack the energy grid and shut off power for millions.   Siobhan Gorman is an intelligence correspondent for the Wall Street Journal.
