“In 2009 and 2010 two separate attacks hit widely-used online gambling payments processors Moneybookers and Neteller. Though they initially appeared innocuous, it now seems both attacks saw millions of users’ private data – addresses, emails, telephone numbers, birth dates and, in the case of Neteller, answers to password hints – fall into criminal hands. The details are only now being made public by Optimal Payments, the London-based owner of both Moneybookers (now Skrill) and Neteller, after disclosure from FORBES. The company is now reinvestigating the hacks and the possibility of further breaches.”
