United Kingdom, March 6 -- Approximately 10 million people had their data stolen when Transport for London (TfL) was hacked in 2024.

The company stated that only "some" customers had been affected at the time, but the BBC has discovered that millions of people had their data taken in what was one of the biggest hacks in British history.

The cyber-attack, carried out by hackers from the Scattered Spider crime group, breached TfL's internal computer systems, disrupting its online services and causing £39 million in damages.

The attack, which occurred between August and September 2024, did not directly affect London transport but led to many TfL online services and information boards going offline.
