Subscriber fraud and account takeover

Subscriber fraud is one of the most damaging operational risks in telecom. Attackers use SIM swap to hijack numbers and intercept one-time passwords, exploit weak authentication on SIP trunking services to spoof caller IDs, and combine voice phishing with social engineering to drain accounts. Decreased customer trust results in higher turnover, and regulators are enforcing stricter rules on caller ID authentication to protect subscribers.

Group-IB Fraud Protection uses behavioral biometrics, device fingerprinting, and explainable AI to detect SIM swap, voice fraud, and account takeover attempts as they happen, before transactions complete. Risk signals are shared across telcos and banks to catch coordinated fraud rings early, which means fewer successful takeovers and less friction for legitimate customers.

When fraud or breach activity escalates beyond automated controls, Group-IB Incident Response contains the threat, identifies the entry point, and reconstructs the attacker’s full kill chain. The team then closes the gaps that enabled the initial compromise, so the same actors cannot return. Operations resume faster, and exposure is reduced before regulators or customers learn of the incident.

Challenge

Customer data breaches

Telecom operators possess a large amount of personal data that is stored across various systems, which makes it susceptible to security breaches. If an attacker gains access to one system, they may be able to reach others, creating multiple pathways for data exfiltration. Data breaches can lead to legal obligations under GDPR and sector-specific regulations, as well as incident reporting requirements and an increase in class-action lawsuits. Tight disclosure timelines mean that a single breach can potentially expose millions of customer records at once.

Gaps in telecom threat intelligence

SOCs struggle with understanding threats, such as identifying IP addresses, malware families, or system owners. Addressing this involves setting up a threat intelligence program, using asset management solutions, conducting system owner interviews, and applying vulnerability and attack surface management tools to gain a comprehensive threat perspective.
