In order to attract new customers, security controls, such as document and identity validations are relaxed in order to facilitate and speed up the subscription process. –The Exploit: Subscription Fraud with either False or Stolen Identification and/or with False Billing Information. –The Fraudsters: Oftentimes professional fraudsters with the objective of turning free calls into cash. Hardened Criminals with the objective of remaining anonymous. Non-professional fraudsters simply wanting free service.
