The zerohedge article has more information than either of those articles. It uses those two as sources, plus some Philippine newspapers. Right now it gives a fairly effective summary of the situation. Switching to either of those would be a downgrade, in my opinion.

The zerohedge article is misleading (e.g. "And yes, it does appear that hackers managed to bypass the Fed's firewall") and lacks any semblance of objectivity.
