Telecom networks are a crucial part of society. They provide services, applications, and communication channels that we simply cannot do without. It’s a critical industry, not just because of the billions of users connected all over the world, but because of the other industries and services that rely on the infrastructure - not least the emergency services.

SS7 network security analysis report

SS7 network security analysis report

February 18, 2020
Whilst the industry is distracted by 5G, Positive Technologies experts lift the lid on the vulnerabilities and threats which plague the 2G/3G networks. The SS7 protocol which is actively used in these previous generation networks can potentially open the floodgates for hackers to exploit - from tracking user location to listening in on calls. Positive Technologies’ SS7 network security analysis report is a deep-dive analysis of the SS7 network threats and recommendations of how telecom operators can protect themselves from this issue which will be a part of the telecoms ecosystems in years to come. The report monitored these vulnerabilities throughout 2019. Companies can use this insight to help them navigate the challenges throughout 2020.

Each generation of mobile networks must interoperate with previous ones. As a result, newer generations inherit the weaknesses of their predecessors. In the first of a series of four reports on telecom security, we look to tackle the misconception that 5G will not be affected by existing security vulnerabilities in mobile networks.

First steps for mitigating Simjacker-related risks right now

First steps for mitigating Simjacker-related risks right now

September 17, 2019
There is nothing that subscribers can do about Simjacker attacks. The vast majority of mobile operators provide SIM cards with STK pre-installed. It is not possible to disable STK on the mobile device itself. Therefore, the job of security falls squarely with mobile operators. And now for the good news. Almost any operator equipment that handles SMS traffic has the capability to reduce the risk of Simjacker exploitation.

5G security issues

July 11, 2019
New-generation 5G networks will be based on existing technologies such as SS7 and Diameter—both of which contain plenty of vulnerabilities. The flexibility of 5G networks means a higher likelihood of configuration mistakes. Making things even more urgent is the growing number of vulnerable IoT devices. Achieving durable security will require concerted efforts by telecom vendors and operators.

June 13, 2018
Despite all the protection mechanisms in the Diameter protocol, networks and subscribers are still at risk. Attackers can exploit numerous SS7 vulnerabilities to successfully track subscriber location, cause denial of service, disconnect thousands of users, or downgrade connections to 3G. Here is our list of recommendations to mitigate security risks both for end users and operators.
