I found an article with more information, but still haven't found out who the sites were.
Officials seize $2M from fake investment companies
...Prime Investment, LTD and Trading 24/7 LTD were shell companies used as a front to transfer large amounts of money into the country while hiding the true source of funds.
edit:
Additional info from the article:
According to Nettles, the two foreign-based companies sent more than $40 million to the US between Oct. 2010 and Feb. 2011.
This was a pre-black Friday operation.
