This book is a mess. I can't tell if Sanger simply doesn't understand technical minutia or if his writing is so sloppy his explanations are useless - probably a bit of both.

The author repeatedly latches on to the most scandalous explanation of certain events, occasionally even acknowledging more mundane explanations are plausible and then proceeding to spend dozens of pages building up the more outlandish story. He extrapolates on scant details and builds complex theories on nothing other than pure speculation.

Further, many of his predictions on the future of cyberwar have simply proven incorrect in places like Ukraine. I can't necessarily fault Sanger for that - pretty much everyone in the information security community made the same forecasts - but nonetheless, they're wrong.

Go read Kim Zetter or Andy Greenberg.
