Ofcom is taking decisive action to close a technical loophole that endangers mobile user privacy and security by banning the leasing of Global Titles. These titles, used for signal messaging in mobile networks, can be exploited by criminals to intercept communications, including sensitive information such as banking security codes. Acknowledging the inadequacy of industry-led solutions, Ofcom aims to safeguard personal data access and enhance telecommunications security. The National Cyber Security Centre has supported this ban, emphasizing the risks posed by unregulated commercial use of Global Titles, urging international regulatory collaboration to address the issue effectively.
This technique, which is actively used by unregulated commercial companies, poses privacy and security risks to everyday users, and we urge our international partners to follow suit in addressing it.
Criminals can use Global Titles to intercept and divert calls and messages, which enables them to capture information held by mobile networks.
Ofcom has taken the step to ban the leasing of Global Titles with immediate effect due to failures of industry-led efforts to address these issues.
Ofcom has stated that the leasing of Global Titles can lead to the security and privacy of mobile users being compromised as their personal data may be directly or indirectly accessed by criminals.
