DHS has warned U.S. banks of the threat of an cyberattack from Al Qaeda. DHS cybersecurity chief Greg Garcia was appointed to fill the long-vacant post back in September. Garcia is known for being a good communicator with lots of experience in the field and a knowledge of how to get things done in Washington. Since his appointment, we’ve heard nary a peep about what he’s up to since his appointment. Is he weighing in privately on what this warning amounts to, even as his spokespeople try to downplay it?”]
