Hacktivists took down Visa’s website after organizing a similar attack on Mastercard.com. The group, called Anonymous, has been encouraging volunteers to download software called LOIC (Low Orbit Ion Cannon) The point of the attacks is to put pressure on financial companies that recently cut ties with WikiLeaks.com over its planned publication of more than a quarter million U.S. Department of State classified cables. The Mastercard website went offline when about 400 computers targeted the LOIC software at it. By the time Visa was hit, there were more than 2,000 people using the software.”]
