A data breach that crossed every moral line. Eight thousand children, families, and staff exposed.

In September 2025, Kido International, a nursery chain operating 18 sites across London and abroad, suffered one of the most disturbing cyberattacks in recent history. A new ransomware group calling itself Radiant infiltrated the organisation using stolen staff credentials and no multi-factor authentication, accessing safeguarding notes, medical records, and confidential family details.

What made this attack unprecedented wasn’t just the breach — it was the cruelty. Radiant contacted parents directly, published children’s photos, names, and home addresses on the dark web, and issued threats demanding a £600,000 ransom. The group’s tactics triggered nationwide outrage, condemnation from cybersecurity experts and government officials, and even backlash from within the cybercriminal underground.

Presented by ProtekCyber, UK-based cybersecurity consultancy helping businesses build clarity, control, and cyber confidence, this episode dissects how poor credential hygiene and weak access controls allowed such a devastating failure in digital safeguarding — and how public pressure forced Radiant into an extraordinary retreat, deleting the stolen data and issuing an apology.

The case stands as a chilling warning that cybersecurity is now child protection — and that failing to enforce basic defences like MFA, encryption, and data minimisation can directly endanger lives.
