The numbers of online fraud and financial scams are rising, according to security experts.

PandaLabs say that many of the scams lure people in with promises of quick and easy money, which play on a victim's financial insecurity. One of the most comon is money mule recruitment scams for people to transfer funds online between countries, which offers $225 or more a day for what they call "rebate processing" work at home.

Ryan Sherstobitoff, chief corporate evangelist at Panda, said that while the U.S. unemployment rate increased by over 6 percent between August and October, reaching a 14-year high of 6.5 percent, dubious work recruitment scams rose 514 percent over that same period. Recruitment spam hit an all-time high as a percentage of total spam, topping 0.31 percent, up from 0.23 percent the previous month and 0.13 percent in August.

PandaLabs says that the success rate for the money mule operations in North America was on average 66 percent higher than the success rates of such scams in other regions. Either Americans are especially thick, or desperate, or both.
