Cybersecurity firm Kaspersky has warned that the telecom sector is likely to face high cybersecurity threats throughout 2026. The growing adoption of modern technologies is expected to increase risks for operators worldwide.
According to Kaspersky’s Security Bulletin, telecom operators faced multiple cyber threats in 2025. These included advanced persistent threats (APTs), supply chain attacks, DDoS disruptions, and SIM-related fraud. The adoption of new technologies introduced additional vulnerabilities, creating operational concerns for telecom networks.
Targeted cyberattacks aimed at gaining covert access to telecom networks remained a serious issue. These attacks allowed hackers to conduct espionage or manipulate network operations. Supply chain vulnerabilities were also highlighted, as a flaw in a single vendor’s software or service could threaten the entire telecom infrastructure.
Kaspersky Security Network data showed that between November 2024 and October 2025:
- 12.79% of telecom users faced web-based threats
- 20.76% of users experienced device-based threats
- 9.86% of telecom companies suffered ransomware attacks
The report emphasized that telecom operators must maintain strong cybersecurity measures. Continuous monitoring of APT activity and critical infrastructure is essential. Operators are also advised to provide regular cybersecurity awareness training for employees.
Kaspersky also recommended introducing AI-based network automation gradually. Human oversight should remain in place for key decisions to ensure safe and secure operations.
The warning underscores the ongoing importance of cybersecurity in the telecom sector. With the increasing reliance on advanced technologies, operators must remain vigilant. Proactive threat detection, employee training, and secure network management are critical to minimizing risks.
