Scattered Spider hackers jailed over 2024 TfL attack

Two members of the Scattered Spider hacking group were sentenced in London on July 16, 2026 for a cyberattack that crippled Transport for London in late August 2024. The attack knocked out more than 140 TfL systems, forced 27,000 staff to reset passwords in person, and cost about 29 million pounds to fix. Both men had pleaded guilty and were each sentenced to five and a half years in prison. UK police said the case severely disrupted the wider Scattered Spider group's activity.

Current status

On July 16, 2026, the UK National Crime Agency said the arrests and jailing of Jubair and Flowers had severely disrupted Scattered Spider's operations; no new developments have been reported since.

Resolved: Services were restored and the incident was closed out.

Who is behind it

Reporting on sentencing day noted Thalha Jubair separately faces US charges over a different, unrelated $87 million extortion scheme against dozens of American firms, and could be extradited after his UK sentence; that case is distinct from the TfL attack.

Impact

The attack made more than 140 TfL systems inoperable, exposed some customer data, forced all 27,000 staff to reset passwords in person, and cost TfL about 29 million pounds to remediate.
