UK Regulator Ofcom Bans Telecom Loophole Enabling Phone Location Tracking
By Raphael Satter
Ofcom Closes Loophole in Telecom System
April 23 (Reuters) – British authorities say they have closed a loophole that could allow rogue actors to secretly track mobile phone users through the international telecommunications system.
Ban on Leasing “Global Titles”
In a statement, the U.K. regulator Ofcom said it had banned the leasing of so-called “Global Titles,” which are special phone numbers that can be used to transmit signaling messages across the global network.
Legitimate Uses and Criminal Exploitation
Such titles are typically used by telecom operators to help ensure the smooth operation of the network – for example by helping deliver messages to users who are “roaming” on other networks – but Ofcom said that criminals could use them “to intercept and divert calls and messages, and get their hands on information held by mobile networks.”
Location Tracking Risks
In some cases, the regulator said the titles “can be exploited by criminals and other harmful actors to track the physical location of individuals anywhere in the world.”
Growing Concerns Over Telecom Vulnerabilities
Cybersecurity professionals are increasingly focused on the vulnerabilities built into the world’s telecommunications infrastructure, some of whose messaging protocols date back decades.
Citizen Lab Report Highlights Surveillance Abuse
Ofcom’s statement came hours before the Canadian internet watchdog group Citizen Lab issued a report on Wednesday covering how suspected surveillance companies were abusing telecom infrastructure to surveil an unnamed “well-known company executive” and track mobile phone users around the world.
