No, it's a mysterious group of masked men and computer hackers called Anonymous who say are committed to dismantling the powerful religious organization renowned for its celebrity members such as Tom Cruise and John Travolta.

Over the past few months, Anonymous has picketed and protested at Scientology centers around the world from Australia and Atlanta to Brussels and Boston. They've also hacked into the church's Web site, posted numerous videos on YouTube criticizing the church and have been accused of harassing church officials.

Now the church is fighting back with its own public relations onslaught, releasing a recent video titled "Anonymous Exposed,"

"Anonymous contains all kinds of individuals, academics, college students, members of law enforcement, media professionals and blue collar workers,"

We have no leaders and adhere to the true definition of a collective."
