Telecommunication companies must be vary of cyber criminals who have the wherewithal to listen to a conversation, accurately pinpoint a person’s location to a meter precision, intercept SMS messages to gain access to mobile banking services, generate USSD commands to a billable number and conduct other malicious attacks.
While it is granted that it is difficult to penetrate the network directly; it is often easy to achieve this feat via the SS7 gateway systems. In some cases, the committed attacker can obtain the operator license in countries with relatively weak laws or obtain access through the black market from a legal operator for a substantial sum of money.
Therefore, it is an area of concern for telecommunication companies and they must invest time in securing their systems thereby protecting their subscribers. SS7 MAP commands allow cell phones to be blocked from a distance. Lack of SS7 security threaten not only mobile subscribers but also a growing ecosystem of industrial and IoT devices — from ATMs to GSM, gas pressure control systems, that are also considered to be mobile network subscribers.
