Three Mobile, Britain’s fourth largest mobile telecoms provider, has now revealed that nearly a quarter of a million of its customers were affected by its data breach in November 2016 – over 76,000 more than they first reported.
The scam’s apparent master plan was to hijack a Three Mobile system used to upgrade customers to new devices, with a view to ordering and then fraudulently selling on new handsets. While no criminal activity has so far been detected, Three is urging customers to take extra caution if someone who purports to be from the company contacts them.
Both the NCA and the NCSC are on the case, with Three’s full cooperation. So far three suspects have been nabbed and are assisting the police with their enquiries.
