Background

Transport for London (TfL) was the victim of the September 2024 cyber attack for which two Scattered Spider members, Owen Flowers and Thalha Jubair, were jailed at Woolwich Crown Court on 16 July 2026, in what the National Crime Agency called Britain's largest-ever cybercrime prosecution.

TfL is the local government body running London's buses, Underground and road network. The 2024 attack disabled 148 systems and exposed data on roughly 10 million passengers, costing an estimated £29 million; the NCA put the potential hit to the UK economy at £56 billion had the network been shut entirely.

The case became a platform for City of London Police to press for new Cyber Crime Risk Orders, restricting convicted hackers' access to technology after release.
