Digital currency company E-gold has been indicted by the U.S. Department of Justice for suspected money laundering and illegal money transmitting. This is interesting as we have seen E-Gold, Webmoney, Western Union, Fethard and other similar services being used by online criminals for quite a long time.
For example, here's a snippet from the Iframecash web site – this gang has been known to use exploits (such as WMF and ANI) to drop drive-by-installs to innocent bystanders' machines.
We have no information whether E-gold staff has been aware of misuse of their services, or whether they have been able to do anything to prevent misuse. But we sure have seen lots of criminals using E-gold.
