Transport for London (TfL)

Transport for London (TfL)

In August 2024, **Transport for London (TfL)** suffered a cyber-attack orchestrated by suspected members of the **Scattered Spider** group, specifically **Thalha Jubair (19) and Owen Flowers (18)**, who were later charged under the UK’s **Computer Misuse Act**. The breach compromised **sensitive personal data of ~5,000 customers**, including **Oyster refund records with bank account numbers and sort codes**. The attack disrupted TfL’s operations, incurring **£30m (~$40.6m) in total costs**, with **£5m (~$6.7m) spent on external recovery efforts**. The incident targeted **critical national infrastructure**, highlighting the group’s focus on high-impact extortion. Jubair alone was linked to **120+ network intrusions** and **$115m in ransom payments** across 47 US entities, with cryptocurrency transfers (e.g., **$8.4m moved during law enforcement seizures**) suggesting sophisticated financial exploitation. The attack underscored the **growing threat of UK-based cybercriminal syndicates** leveraging **social engineering** to infiltrate systems, extort victims, and evade detection through minimal digital trails.
