In what appears to be the largest leak of C.I.A documents in history, WikiLeaks released on Tuesday thousands of pages describing sophisticated software tools and techniques used by the agency to break into smartphones, computers and even Internet-connected televisions.
The documents amount to a detailed, highly technical catalog of tools. They include instructions for compromising a wide range of common computer tools for use in spying: the online calling service Skype; Wi-Fi networks; documents in PDF format; and even commercial antivirus programs of the kind used by millions of people to protect their computers.
A program called Wrecking Crew explains how to crash a targeted computer, and another tells how to steal passwords using the autocomplete function on Internet Explorer. Other programs were called CrunchyLimeSkies, ElderPiggy, AngerQuake and McNugget.
The document dump was the latest coup for the antisecrecy organization and a serious blow to the C.I.A., which uses its hacking abilities to carry out espionage against foreign targets.
