As the Apple v FBI battle unfolds, government backdoors will become a hot topic. As background to that, I have two questions:
- Are there any known cases where governments have forced tech companies to introduce backdoors into their products? (I'm not talking about accidental security holes that governments have been able to exploit, nor am I talking about companies simply handing over unencrypted data in their posession.)
- Are there any cases where a government backdoor have been exploited by other actors, or information on how to use it has become publicly available, thereby creating a serious security threat to the users of the product?
I am interested in examples from all around the world, both new and old. Basically what I want to have is examples to use as an efficient rebuttal to the argument "Well, a backdoor only the government knows about couldn't possibly hurt anyone."
