Telecom company suffers a 5-year-long hack

A US text message routing company has revealed a hack dating back to 2016. Syniverse, a telecoms business that routes text messages for major US mobile phone networks, announced that it “became aware of unauthorised access to its operational and information technology systems by an unknown individual or organisation.” After notifying authorities and running an investigation, the Syniverse team discovered that the initial hack probably took place in May 2016. Billions of text messages per year are routed through Syniverse. A company review revealed that more than 200 clients and possibly millions of mobile phone users could have been affected to some degree.
