At a time when there is controversy about the rejection by various countries of Huawey equipment, it is interesting to find more about hacks attributed to sources within China. It is also interesting to read the report by professor Anne-Marie Brady about the influence of that country in New Zealand. For memory, her office and home were burglared following the publication of the report, and the breaks on her car were sabotaged. Probably a coincidence, as the police found nothing to incriminate anyone.
I do not believe that the attacks are one way in any case.
