Ransomware attacks represent about 22 percent of all global incidents NTT Security, an information security and risk management firm, handles for clients, said Kai Grunwitz, the firm's senior vice president for central Europe. It's a warning that cyber attacks soon may be as frequent as, well, the scenario played out in Groundhog Day, thanks to a top-secret agency tasked with keeping us safe. "This attack provides yet another example of why the stockpiling of vulnerabilities by governments is such a problem".
