Cybercriminals are continuing to innovate within the mobile market segment, with the general availability of TDoS (telephony denial of service) value-added services. This development has been enabled by the commercial availability of non-attributable SIM cards, a supply of easy to use cybercrime-friendly tools and services, evolved CAPTCHA-solving API-enabled processes, plus the evident vertical integration within the managed/for-hire DDoS (distributed denial of service) market segment.. These continuing advances demonstrate cybercriminals’ long-term interest in monetizing the ever-increasing number of international mobile users.

We’ve recently spotted a new, cybercrime-friendly ‘virtual mobile number’ on demand service. It provides potential customers with the ability to utilize an unlimited number of virtual mobile numbers for a variety of cybercrime-friendly activities, including the bypassing of SMS/phone-based pre-authentication checks, commonly used to secure registration services.
