Courtney Stodden -- Sex Tape Interruptus ... Thanks to Hackers

Courtney Stodden's big sex tape debut was derailed by hackers who were trying to steal the code and pilfer the porn.

Vivid.com unveiled Courtney's solo tape Thursday and everything was humming along, until the IT department noticed someone was trying to steal the code to the tape.

Vivid honchos believed the hackers were gunning for some kind of general release, bypassing the porn giant ... so the IT department shut down the entire site for more than an hour while they figured out how to block the hackers.

Vivid says the cyber attack failed. Poor hackers -- where will they ever find porn on the Internet?
