DCNS Security Breach

CRITICAL-77
DCN2114291023
The French submarine company DCNS, which Thales owns 35 percent of, was the target of a security breach that is being looked into by Indian authorities. After more than 22,000 papers about six DCNS Scorpene submarines that were being built in India were leaked, the investigation was launched. The appropriate national French authorities for Defence Security are looking into this matter seriously. This inquiry will ascertain the precise nature of the documents that were leaked. Although the source of the documents has not been disclosed, the Australian has established that the security breach may have major implications for a $38 billion project that the DCNS is currently negotiating with the Australian government.
