Text messaging service firm Syniverse says hackers first gained access to its systems in May 2016. The company routes text messages for the vast majority of the world’s mobile phone carriers. “The information flowing through Syniverse’s systems is espionage gold,” says Sen. Ron Wyden, D-Ore., who says the industry should face mandatory cybersecurity standards. Syniverse is set to go public by the end of the year, valued at $2.85 billion. It counts about 1,250 customers across almost 200 countries, including 95 of the top 100 mobile carriers.”]
