Although a YouTube video uploaded on Monday indicates the hacker group Anonymous has vowed to erase the New York Stock Exchange from the internet on Oct. 10 to support the Occupy Wall Street movement, the statement has been refuted by other Anonymous outlets that claim the video was a hoax.

The video was posted by a user called The Anonymous Message, who has uploaded 13 videos onto the Web site in the last two months. The video carries the Anonymous logo and calls its plan to hack into the NYSE Operation Invade Wall Street.

On Oct. 10, NYSE shall be erased from the Internet. On Oct. 10, expect a day that shall never, ever be forgotten, the video, which consists of a voiceover in front of the Anonymous symbol, states.

Last week, the same user posted a video including a threat to carry out a cyber-attack on the New York Police Department, which does not seem to have actually occurred.

However, one widely circulated statement that appeared on the Daily Kos by the user Anonymous Dkos said the video was not a legitimate message from the group.

Operation Invade Wall Street is bull----! It is a fake planted operation by law enforcement and cyber crime agencies in order to get you to undermine the Occupy Wall Street movement, the statement said.

Hoax Aimed at Tarnishing Occupy Wall Street Activists' Image?

Meanwhile, the hashtag #InvadeWallStreet has popped on Twitter through many Anonymous-related accounts, warning would-be participants that the attack is aimed at creating bad press for both Anonymous and the Occupy Wall Street movement.

On Tuesday, one Twitter account called AnonyOps posted #invadewallstreet #IWS possibly a psyop? ...Don't get roped in by those who want 2 see #occupywallstreet fail.

While some of the tweets under #InvadeWallStreet advocate the plan, most of the messages by Anonymous-affiliated accounts contain warnings that the event is a set-up.
