Hack attack spurs call for more N. Korea sanctions
Suspicions that North Korea was behind a destructive hacking attack against Sony Pictures and a threat against movie theaters are intensifying calls for tougher US steps to cut that country's access to hard currency and declare it once more as a state sponsor of terrorism.
At first glance, US options for responding to the hacking attack are limited. Bringing the shadowy hackers to justice appears a distant prospect. A US cyber-retaliation against North Korea would risk a dangerous escalation. And North Korea is already targeted by a raft of sanctions over its nuclear weapons program.
