The report highlights first that mobile networks, devices and consumers are experiencing a full spectrum of attacks across the globe. This report analyses these attacks and identifies six key themes for attention:

• Software implementations as a key frontline of attacks
• A democratisation of attacks, whereby there is a lowering of the technical and resource barriers to launch attacks
• Pre-positioning attacks that seek to establish a bridgehead for later attacks
• Exploitation of weak cyber hygiene
• Supply chain attacks
• Scam attacks on mobile consumers

This years report follows a new format and approach to the 2025 Mobile Telecommunications Security Landscape Report:

• 6 main attack types identified; each with definition, indicators of compromise and example mitigations New content covering threat actors and their MOs
• Two main security responses areas: risk management and CVD
• Two main forward-looking topics Generative and Agentic AI and PQC
