According to the latest information from the Network Security Bulletin, in 2025, network operators continue to be under pressure from targeted attacks (APT), supply chain vulnerabilities, distributed service denial-of-service (DDoS) attacks and forms of fraud through phone SIMs, while the deployment of new technologies brings additional operating risks.
Stepping into 2026, the telecommunications industry is moving from the technology testing phase to widespread deployment. According to Kaspersky, this process both opens up development opportunities and poses many new risks if not strictly controlled. The report points out three technology fields that, if deployed inconsistently or without appropriate control mechanisms, could cause disruptions in the operations of network operators.
- Firstly, the application of artificial intelligence (AI) in network management. Although AI helps automate many operating stages, it can also cause errors to spread faster if the system is malconfigured or data processing is inaccurate.
- Second is the application of new encryption technologies to prepare for the advent of quantum computers in the future. If deployed hastily, these technologies may make systems operate incompatibly with each other, slow down the network or cause errors in operation.
- Third is the trend of integrating 5G with satellites (NTN), helping to expand coverage but at the same time increasing the number of partners and connection points, thereby generating more risks of errors and risks in system stability.
To minimize risks and enhance resilience to cyber threats, Kaspersky experts recommend:
Network operators need to closely monitor targeted attacks targeting the telecommunications industry and related systems: Kaspersky Threat Intelligence Portal helps network operators grasp information about attack groups and ongoing campaigns, and at the same time needs to combine and strengthen periodic security training programs so that employees can promptly recognize suspicious signs and strictly comply with security regulations.
Applying AI to network operation: It needs to be carried out cautiously, step by step, with human supervision and clear control mechanisms to avoid risks because AI can make wrong decisions that have widespread impact.
Proactively prepare to cope with distributed service denial-of-service (DDoS) attacks: Consider this an issue to ensure the system is always operating stably and does not disrupt services.
This includes checking the ability to prevent attacks from external systems, protecting important network connection points and early monitoring of signs of overload to promptly handle before affecting users.
Deploy EDR solutions such as Kaspersky Next EDR Expert: To detect sophisticated threats early, support rapid investigation and improve efficiency in zoning, handling and overcoming security incidents.
