Software used by an electronic voting system manufactured by Sequoia Voting Systems has been left unprotected on a publicly available server, raising concerns about the possibility of vote tampering in future elections.

The software, made available at ftp.jaguar.net, is stored on an FTP server owned by Jaguar Computer Systems, a firm that provides election support to a California county. The software is used for placing ballots on voting kiosks and for storing and tabulating results for the Sequoia AVC Edge touch-screen system.
