Our democracy has been hacked.
Why it is hard sci-fi
A hacking procedural with the unusual property that the hacks on screen are real. Tools, exploits, and methods are correct, the lab consultants are working security professionals, and the show uses real Tor, real Kali, and real social-engineering procedures. The political backdrop is a near-present in which a small group plans the destruction of the global financial sector by encrypting a critical archive. The procedural rigour is in the keystrokes.
Science inside it
Real-world penetration testing, social engineering with documented techniques, a femtocell rogue base station for SMS interception, and a working portrayal of dissociative identity disorder as a clinical reality rather than a plot device. The shows engineering is usually good enough that security professionals can name the exact tool from a frame.
