Mules have been considered to be the “bottleneck” of fraud. While fraudsters have the capabilities of stealing millions of credentials, eventually they can cash out only as many mules as they have access to. Fraudsters are aware of it just as much as security professionals and they invest their efforts, resources, time and ingenuity to open this bottleneck as much as they can.
Because of it, we can expect new scams and innovations coming from fraudsters not only in the realm of obtaining credentials or new ways to cash them out, but also in establishing the infrastructure that allows them to do just that.
