As more details emerge about how a group of four Russians breached Yahoo, it's increasingly clear that the Internet's very interconnectedness is what makes us so vulnerable to online attacks. It's enough to want to just unplug from the Internet and go back to semaphore and Morse code.

The Justice Department's indictments against four individuals allegedly responsible for the two attacks against Yahoo in late 2014 and August 2013 included several bombshells, including the fact that two members of the Russian FSB were involved. Yahoo had previously stated the attackers had stolen names, recovery email addresses, telephone numbers, hashed passwords, and birthdates from more than a billion victims. The indictment claimed the attackers used data gleaned from the stolen cache to carry out secondary attacks against a smaller, targeted set of victims.
