Secret information on counter-terrorism shared by foreign governments may have been compromised by a massive data theft by a senior IT technician for the NDB, Switzerland‘s intelligence service, European national security sources said.
Intelligence agencies in the United States and Britain are among those who were warned by Swiss authorities that their data could have been put in jeopardy, said one of the sources, who asked for anonymity when discussing sensitive information.
Swiss authorities arrested the technician suspected in the data theft last summer amid signs he was acting suspiciously. He later was released from prison while a criminal investigation by the office of Switzerland‘s Federal Attorney General continues, according to two sources familiar with the case.
