The hacker world 
has been a busy one lately.
The blend of high-profile cyber intrusions and denial of service attacks, mixed with vague anonymous threats delivered by mechanized voices and curiously timed offline periods for major corporations, have prompted some conspiracy theorists to wonder — Is there a hacker movement underway to undermine big business and/or the economy?
No one in the entertainment world 
wants to be Sony these days.
After a security breach resulted in the theft of personal information in more than 100 million user accounts, it didn’t seem things could get much worse. But a series of rapid-fire smaller hacks to sites in Canada, Thailand and Indonesia — along with an exploit on Sony’s PlayStation site that temporarily put accounts at risk again — continued to endanger the company’s reputation with consumers.
Instead of the muffled competitive snickering that usually occurs when a rival stumbles, other entertainment companies have watched in fear as the drama has played out, knowing that their own online operations were spared only by the whim of the hacking community.
Frequenters of infamous U.S.-based website 4chan.org have declared war on Hollywood.
Its users led the charge in a distributed denial of service attack on the MPAA and RIAA websites Monday — blocking their pages for hours.
The move, say the anonymous attackers, was in retaliation to action the orgs have taken to squash filesharing sites such as Pirate Bay.
If you had trouble accessing the Web sites 
for the MPAA and RIAA earlier today, you’ve got 4chan to blame.
The infamous Internet imageboard (and hangout of film piracy advocates) launched a coordinated DDoS (distributed denial-of-service) attack on the industry sites Monday – allegedly in a retaliatory move for the trades’ moves to squash filesharing Websites.
