Although most investigators and credit card fraud teams focus on minimizing cybercrime and identity theft activities launched through spam attacks, the California teams discovered a network of businesses that developed complex fulfillment systems to prevent chargebacks and to encourage repeat business.Under this model, a team of spammers could make more money over time selling many of the same goods to repeat customers than by simply selling credit card account details to fraud rings. Out of 56 completed transactions during the study, only seven of the team's orders failed to arrive.Though top rated credit cards already offer significant consumer protection, few customers feel compelled to file transaction disputes after packages arrive from fulfillment centers in India, China, and even the United States.Visa, MasterCard could team up to block spam fundingEfforts by the technical community to block consumers' access to potentially fraudulent websites have often been thwarted by a combination of hacker attacks and customer frustration. The researchers suggest that American credit card issuers could help curb the growth of spam-sending botnets by choking off the supply of cash to merchants on a "financial blacklist."The team suggested that a partnership between credit card platform providers like Visa and MasterCard could eliminate many spammers' financial incentives, just as a similar enforcement action closed off most Americans' access to illegal online gambling operationYemen's Interior Ministry denied the base's capture in a statement. Saif said the tribe attacked the base to prevent its soldiers from heading to Sanaa to reinforce government troops there. The Republican Guard is one of Yemen's best trained and equipped forces. It is commanded by one of Saleh's sons and has remained loyal to the president even as other military units have defected. Late Friday, tribal fighters seized another army base nearby after striking a deal with the soldiers inside that allowed them to leave with their personal weapons, local tribal leader Abdul-Moin al-Sharif said. No one was injured. The week's fighting has terrified residents of the capital Sanaa, and many have packed up their cars and fled the city. Tens of thousand massed in the central square that has been the focus of the anti-Saleh protests for a march they said sought to "confirm the peacefulness of the revolution." Addressing the crowd, Sheik Sadeq al-Ahmar, head of the Hashid, blamed Saleh for the week's violence. "The war came down on our heads, but are holding strong and victorious," the 55-year-old leader said. "We want to remain peaceful, but if Ali Abdullah Saleh wants war, we are ready to face him and those around him." For the first Friday since the uprising began, Saleh did not hold a boisterous rally for his supporters, apparently due to security concerns. U.N. humanitarian chief Valerie Amos said she was "deeply alarmed by the escalating violence in Yemen" and called on all parties to protect civilians "and to spare them from the effect of further hostilities." She cited reports of many families leaving Sanaa and expressed concern that "continued confrontations could force large numbers of people to flee their homes, with serious humanitarian consequences." "Many Yemenis already face shortages of food, fuel and other basic necessities," Amos said in a statement. "The U.N. is monitoring the situation, and stands ready to offer assistance if needed." The battles broke out Monday after an attempt by government forces to storm al-Ahmar's compound in the heart of Sanaa. By Thursday, the clashes had widened to include areas around Sanaa's airport, and other tribes had joined in alongside al-Ahmar's Hashid. On Friday, however, there were no reports of fighting in Sanaa, and Hashid gunmen solidified control over government buildings they'd seized, setting up checkpoints and searching those seeking to pass. The fighting could open a new chapter in Yemen's turmoil. Until now, Saleh's opponents have stuck to peaceful protests massing hundreds of thousands around the country. Several military units, along with tribal powerhouses like the Hashid, have joined the opposition, but they have avoided violent confrontations with Saleh's loyalists. But Saleh has managed to cling to power despite defections, protests and pressure from Arab neighbors and Western powers to leave office. Efforts to mediate his exit collapsed last week when the president refused to sign a deal for him to step down in 30 days. Saleh has retained the loyalty of the regime's most elite military units — all commanded by close relatives. The escalation with the tribes could strain that hold. Under Yemen's ancient codes, tribal leaders can declare that members follow their orders above all others — potentially forcing soldiers in pro-Saleh units to choose between their clan and military loyalties. So far, there have been no apparent signals of mass defections from the pro-Saleh units since the fighting with the Hashid began. Most of Ye
