Macau telecom service failure linked to cyber attacks

Macau’s telecom service provider, Companhia de Telecomunicacoes (CTM), suffered its second blackout in four months earlier this week.  It reported that there had been a “high volume of irregular overseas traffic flowing into its DNS server”, the kind of activity which is often associated with hacking attacks. 

When a similar incident occurred last July, Macau officials sent a letter to the US consulate in Hong Kong asking whether it was the target of NSA surveillance.  Chief executive Chui On San confirmed the attacks and the cases are being investigated by the Judiciary Police.
