Sony Pictures Plans Town Hall as Hackers Promise 'Christmas Gift to Come'

The FBI is reportedly advising employees on how to manage data leaks.

“It’s hard to believe they could be bracing for much worse, but I’ll bet you, they are,” Wallenstein said.

In the latest round of embarrassing leaks, an early version of the top-secret script to the newest James Bond movie, “Spectre,” was stolen as filming was set to begin, which Wallenstein says could prove expensive.

“It could cost up to $100 million just to clean up the mess that these leaks are causing,” Wallenstein said.

Sony launched a counterattack to the cyberwar, sending a letter to news organizations, including ABC News, asking them to delete and avoid publishing what it calls “stolen information.”
