September 20, 2025

London, United Kingdom – Two teenagers are now facing prosecution following a prolonged cyberattack against Transport for London (TfL) that initiated on August 31, 2024, and resulted in months of operational disruptions and substantial financial losses.

Authorities have connected teh intrusion to Scattered Spider, a cybercriminal institution increasingly recognized as a major threat to critical infrastructure. The National Crime Agency (NCA) confirmed the arrests and subsequent charges, highlighting the complexity and duration of the investigation.

Thalha Jubair,19,from east London,and Owen Flowers,18,from Walsall,were taken into custody at their respective homes by a joint operation involving the NCA and City of London Police. Both individuals have been remanded in custody pending trial in October.

Extensive Damage and Financial Impact

The cyberattack led to significant disruption of TfL’s systems, impacting various online platforms and digital facts resources for an extended period. The NCA estimates the financial damage to be in the millions, a figure that reflects not only immediate repair costs but also long-term operational consequences.

Flowers was already under bail conditions related to other offenses when the TfL attack occurred. Subsequent investigations revealed evidence linking him to attacks targeting healthcare organizations in the United States, leading to additional charges. Jubair stands accused of obstructing the investigation by refusing to disclose passwords for seized electronic devices.

Paul Foster, Deputy Director and head of the NCA’s National Cyber Crime Unit, emphasized the seriousness of the incident, stating, “This attack caused significant disruption and millions in losses to TfL, part of the UK’s critical national infrastructure.” He further underscored the increasing threat posed by cybercriminals originating from the UK and English-speaking countries,with Scattered Spider being a prime example.

Hannah Von Dadelszen, Chief Crown Prosecutor for the Crown Prosecution Service (CPS), affirmed the strength of the evidence, stating that prosecutors determined sufficient grounds existed for a trial and that pursuing criminal proceedings was in the public interest.

TfL officials released a statement acknowledging the charges and expressing gratitude to the National Crime Agency for their diligent work. The attack prompted TfL to alert approximately 5,000 customers about potential compromise of their banking and personal information.

This incident aligns with a broader trend of young individuals being implicated in large-scale cyber offenses. Recent cases include attacks on major retailers like M&S, Co-op, and Harrods, and also breaches targeting educational institutions.

Do you think critical infrastructure is adequately protected against these types of attacks? What further measures could be implemented to enhance cybersecurity defenses?

Understanding the Growing threat of Cyberattacks

Cyberattacks against critical infrastructure are becoming increasingly frequent and sophisticated. The rise of ransomware-as-a-service (RaaS) has lowered the barrier to entry for cybercriminals, allowing even individuals with limited technical skills to launch damaging attacks. According to a report by the UK government’s Cyber Security Breaches Survey 2023, 39% of UK businesses experienced a cyberattack in the last 12 months.

The impact of these attacks can be far-reaching, extending beyond financial losses to include disruptions in essential services, damage to reputation, and erosion of public trust. Proactive cybersecurity measures, including regular vulnerability assessments, employee training, and incident response planning, are essential for mitigating these risks.

Pro Tip: Regularly update your software and operating systems to patch security vulnerabilities. Enable multi-factor authentication (MFA) whenever possible to add an extra layer of protection to your accounts.
