In one of the U.S. government's largest anti-piracy crackdowns ever, f
ederal agents on Thursday arrested the leaders of and shut down Megaupload.com, a popular hub for illegal file sharing.
Hours later, Megaupload's fans turned the table on the feds. "Hacktivist" collective Anonymous said it set its sights on the U.S. Department of Justice and apparently knocked the agency's website offline.
"
We are having website problems, but we're not sure what it's from,"
a DOJ spokeswoman told CNNMoney.
The DOJ website glitches came soon after various Twitter accounts associated with Anonymous took aim at the agency.
Anonymous's favorite weapon for these attacks is what's called a "distributed denial of service" (DDoS) attack, which directs a flood of traffic to a website and temporarily crashes it by overwhelming its servers. It doesn't actually involve any hacking or security breaches.
"
One thing is certain: EXPECT US! #Megaupload" read one tweet from AnonOps that went out mid-afternoon.
One hour later, the same account tweeted a victory message: "
Tango down! http://universalmusic.com & http://www.justice.gov// #Megaupload"
Universal Music's website also went down Thursday afternoon. The music company had been locked in a legal battle with Megaupload over a YouTube video that featured many of Universal Music's signed artists promoting Megaupload's site.
The websites of the Recording Industry Association of America and Motion Picture Association of America also went down Thursday afternoon. On Twitter, AnonOps took credit for the crashes.
The Anonymous attack came soon after the DOJ announced the indictment of seven individuals connected to Megaupload for allegedly operating an "international organized criminal enterprise responsible for massive worldwide online piracy of copyrighted works."
