OFCOM has explained that “leading” measures taken to prevent criminal mobile networks from maliciously intercepting text messages, including bank security codes.
The regulatory authority has announced a ban on the leasing mirror of special types of telephone numbers that are referred to as global titles and used by mobile phone networks to support services by ensuring that messages and calls reach the intended recipient.
The telecommunications regulator said that previously global titles could be rented to third parties, which led to a technical gap in which criminals could possibly receive and intercept messages, including security codes that are sent to bank customers via SMS.
In response to the fact that OFCOM is now prohibiting the leasing of global title.
📵 We close a technical gap in mobile phone networks with which criminal calls, texts and the locations of the people follow.
Our new rules have this practice and protect British mobile users from serious data protection and security risks.

Natalie Black, group leader of the regulatory authority for network and communication, said: “We take leading measures worldwide to cope with the threats from criminals that receive access to mobile phone networks.
“Rental global titles are one of the most important and most persistent sources for malicious signals.
“Our ban helps prevent you from falling into the wrong hands – the protection of mobile users and our critical telecommunications infrastructure.”
OFCOM said the risk that is equipped by the leasing global title was recognized by organizations, including the British National Cyber ​​Security Center (NCSC), but so far the efforts to solve the problem were not effective.
For this reason, it is to get in to introduce the leasing ban.
“This technology, which is actively used by non -regulated commercial companies, represents privacy and security risks for everyday users, and we ask our international partners to follow.
“As the national technical authority of Great Britain for cyber security, we also congratulate OFcom on their continued global leadership in this critical area.”
