Kaspersky has warned that the growing use of new technologies is likely to keep cybersecurity threats in the telecom sector high through 2026.

The Russian cybersecurity firm cautioned that even in 2026, the telecom sector will continue to face cyberattacks fueled by the expansion of modern technologies.

According to Kaspersky’s Security Bulletin, in 2025, advanced persistent threats (APTs), supply chain attacks, DDoS disruptions, and SIM-related fraud continued to put pressure on telecom operators, while the adoption of emerging technologies introduced new operational concerns.

The report highlighted that during 2025, telecom operators faced multiple serious threats. Targeted cyberattacks aimed to gain long-term covert access, enabling espionage and influence within networks.

Supply chain vulnerabilities also remained a major concern, as telecom networks depend on multiple vendors and integrated platforms, meaning that a flaw in a single software or service could pose a risk to the entire network.

According to Kaspersky Security Network data, between November 2024 and October 2025, 12.79% of telecom sector users faced web-based threats, while 20.76% were affected by device-based threats. During the same period, 9.86% of telecom companies worldwide experienced ransomware attacks.

Kaspersky recommended that telecom operators maintain a constant focus on threat intelligence, monitor APT activities and critical infrastructure, and ensure regular cybersecurity awareness training for employees.

The report also advised that AI-based network automation be implemented gradually, with human oversight maintained for key decisions.
