Telecommunications business Syniverse, which routes text messages for the vast majority of the world’s mobile phone carriers, has disclosed that its systems were breached for five years.
“In May, Syniverse became aware of unauthorized access to its operational and IT systems by an unknown individual or organization,” the company says in a filing to the U.S. Securities and Exchange Commission dated Sept. 27. “Promptly upon Syniverse’s detection of the unauthorized access, Syniverse launched an internal investigation, notified law enforcement, commenced remedial actions and engaged the services of specialized legal counsel and other incident response professionals. Syniverse has conducted a thorough investigation of the incident.”
