In the wake of the Sony Pictures hack, Washington is showing a new focus on the threat posed by North Korea. The House Foreign Affairs Committee has called for a public briefing on Tuesday that will examine the country's hacking capabilities, with testimony from the Departments of State, Treasury, and Homeland Security. The briefing will focus on steps the US is taking to curtail or protect against the country's apparent capabilities. "There can be no doubt that the Kim regime means America harm," Chairman Ed Royce (R-CA) said in a statement, "and as we saw last month, Pyongyang can deliver on its threats."

President Obama has already ordered new sanctions against North Korea in direct response to the attack, but has also hinted at further measures yet to come, calling the sanctions the "first aspect" of the government's response. Others in Congress are also calling for new defensive measures, resurrecting the controversial CISPA cybersecurity bill. Given the newfound interest in digital defense, supporters see this as the bill's best chance to get through Congress. On Wednesday, FBI director James Comey reiterated his confidence that the nation was responsible, saying, "we know who hacked Sony. It was the North Koreans."
