Our recent research aims to shed more light on this topic, and reveal conclusive evidence that such a leak did actually take place years before the Shadow Brokers leak, resulting in 🇺🇸 US developed cyber tools reaching the hands of a 🇨🇳 Chinese group which repurposed them in order to attack US targets.
Cyber weapons are digital and volatile by nature. Stealing them and transferring from one continent to another, can be as simple as sending an email.
