The online collective Anonymous is disputing a YouTube video posted over the weekend that promises distributed denial-of-service attacks on Monday against the New York Stock Exchange. In a tweet from the AnonOps Twitter account, considered one of the most trusted sources of information from the group, there are no plans to hack Wall Street properties. Because Anonymous is technically a leaderless organization, it is sometimes difficult to tell if information is accurate. The FBI declined comment on the matter, when reached by SCMagazineUS.com. Anonymous has been instrumental in recent weeks in facilitating the Occupy Wall Street ground protests, which have now spread beyond New York to a number of other cities.
