Chinese hackers are stepping up their game, according to Nigel Inkster, the former director of operations for Britain’s MI6. He says they are taking on a new swagger in cyberspace and borrowing things from a familiar playbook: a Russian one.

The US and UK made a splashy coordinated announcement last month about a years-long cyber espionage campaign by Chinese state-backed hackers. The US indicted seven, the UK leveled sanctions. They just neglected to do one thing --- let some of the victims know.
