Hackers Attack Sites That Thwarted WikiLeaks

A small army of activist hackers orchestrated a broad campaign of cyberattacks in support of the beleaguered antisecrecy organization WikiLeaks, which has drawn governmental criticism from around the globe for its release of classified American documents and whose founder, Julian Assange, is being held in Britain on accusations of sex offenses. Targets included Mastercard.com, which stopped processing donations for WikiLeaks; Amazon.com, which revoked server space from the group; the online payment service PayPal, which cut off its commercial cooperation; the lawyer representing the two Swedish women who have accused Mr. Assange in the sex case; and PostFinance, the Swiss postal system’s financial arm, which closed Mr. Assange’s account after saying he provided false information by saying that he resided in Switzerland.
