Mysterious Shadow Brokers group re-emerges to taunt U.S. intelligence

The day after a particularly virulent strain of ransomware burst across the globe, the mysterious Shadow Brokers group has re-emerged to taunt the U.S. National Security Agency. 

It's a possible hint at the shadowy spy games being played behind the scenes of the cybersecurity crisis that struck Ukraine, Russia and countries around the world Tuesday.

The Shadow Brokers, who have spent nearly a year publishing some of the American intelligence community's most closely guarded secrets, posted a new message to the user-driven news service Steemit on Wednesday carrying new threats, a new money-making scheme and nudge-nudge references to the ransomware explosion that continues to cause disruption from Pennsylvania to Tasmania.
