The Perfect Weapon is the riveting story of how, in less than a decade, cyberwarfare displaced terrorism and nuclear attacks as the greatest threat to American national security. Cheap to acquire, difficult to defend against, and designed to shield their user's identities so as to complicate retaliation, these weapons are capable of an unprecedented range of offensive tactics; they can take us just short of war, allowing for everything from disruption to theft to the cause of widespread damage of essential infrastructure systems. And the vulnerability of those systems has created a related but equally urgent conflict: American companies like Apple and Cisco must claim allegiance to no government in the name of selling secure products around the globe yet the US intelligence agencies want the help of such companies in defending against future cyberattacks. Reported and written with unprecedented access by New York Times chief Washington correspondent and bestselling author David Sanger, The Perfect Weapon takes readers inside war rooms and boardrooms, into the secret cyberdens of American and Chinese military, to give the deep-background story of the increasingly pitched battle between nations, their governments, their cyberwarriors, and their corporations.

    The 4,000-year history of cryptography has been a kind of arms race: Each time a more complex encryption has been developed, it has been attacked and, more often than not, decoded; and each time, in response, codemakers have produced tougher and tougher codes. Codebreaker surveys the entire history of codes through an eloquent narrative and an evocative range of illustrations, paying special attention to famous codes that have never been broken, such as the Beale Ciphers, the Voynich manuscript, the Easter Island code, and many more. Many great names in history appear throughout, from Caesar and Mary Queen of Scots, to Samuel Morse and Alan Turing. The narrative is based in part on interviews with cryptology experts, Navaho windtalkers, decryption experts, and law enforcement experts, and ends with a vision of the coded future via quantum cryptography.

    By May 1919, when the power struggle between former Tsarists and Bolsheviks hangs in the balance, the only British agent in Russia is trapped and in mortal danger. Mansfield Cumming (alias "the first C") dreams up an audacious-probably suicidal-plan to rescue him, and a young naval officer is sent with a specially selected team into the jaws of the Soviet fleet. This is the remarkable true story of the spy Paul Dukes (the only MI6 officer to be knighted for work in the field) and Gus Agar, whose extraordinary escapade won him the Victoria Cross.

    The Russian army was camped on the other side. When the signal came to begin Operation Barbarossa he and his comrades from the German Wehrmacht stormed over the River and began an assault that took millions of Germans deep into Russian territory. For some the journey was brief. For others, like Oskar, it would last for years, and the struggle did not end when the fighting was over. This is the story of one German soldier’s experience in combat and captivity. It is the story of bravery, despair, deception, and survival.
