No doubt about it: everyone from Anonymous to the Chinese are listening in on “secure” conference calls. They listened in on some, regarding the F-35 Joint Strike Fighter, about three years ago. Which is dismaying.
They got details on control software (designed with no security in mind), as well as special communications and antenna arrays. They snooped into government systems, and propagated their attacks to infect contractors to the project, who then had serious problems of their own.
But no! The Chinese are our friends and trading partners. We can trust them, right?
