For major financial institutions, their best asset in the fight against fraudsters is their ability to follow the money, in this case the money mules. As argued below, the most important recent trends in this type of scam are as follows:
- Increasing general sophistication in the verbiage used in spam e-mails and scam Web sites.
- Increasing use of Rock Phish-style tactics for hosting scam Web sites on a wide variety of URLs to avoid shutdown.
- Increasing use of Hong Kong–based top-level domain registrars (particularly Hong Kong Domain Name Registration [HKDNR]), which scammers perceive (rightfully or not) are less likely to respond to abuse reports.
