A typical e-fencing strategy is very straightforward—research loss data, surf the net, identify possible online fences and shut them down. Of course, this sounds much simpler than it actually is. There are literally dozens of Internet sites where a cyber-criminal can fence stolen goods. The most popular sites are eBay, Craigslist, Letitgo, and Amazon.com. On any given day, eBay will list in excess of 100,000 individual auctions of just Limited Brands merchandise. Determining where to begin your investigation, therefore, requires thorough data analysis, knowledge of the inner workings and policies of offending Internet sites, professional instinct, and a little bit of luck.
