An anonymous reader writes "The all-volunteer based online fraud fighting group CastleCops.com is currently the target of ongoing reputation-based attacks in which criminals use phished PayPal accounts to donate thousands of dollars to CastleCops from dozens of victims. This attack appears to be in response to a recent series of failed denial-of-service attacks against the CastleCops, Web site. From the story: 'A few donations were for as little as $1, while other fake donations ranged as high as $2,800. To the victims of the stolen PayPal accounts, it looks as if CastleCops is the one stealing their money, when in reality, it's the attackers. Also, the fraudulent activity seeks to ruin their relationship with PayPal.' In a comment left on Washingtonpost.com's Security Fix blog, CastleCops co-founder Paul Laudanksi says while the group's site remains under a heavy DDoS attack, it is currently down due to a hardware failure, not the attack itself."
