In February 2024, Hamilton was hit by a devastating cyberattack. Nearly 80% of the city’s digital systems were locked down overnight, and the hackers demanded an $18.5 million ransom. What made headlines? Hamilton Cyberattack: Insurance Didn’t Help. When the city looked to its cyber insurance, they were left on their own to pay the $18.3 million recovery bill because the insurer said Hamilton failed to meet key policy requirements.
How the Breach Happened
- Unsecured Server: Hackers accessed the city’s network through an internet-facing server with no extra protection.
- Missing Multi-Factor Authentication (MFA): Departments ignored warnings, skipping vital MFA safeguards required by insurance.
- Rapid Spread: Once inside, hackers quickly locked down core city services before staff could react.
Why Insurance Refused To Pay
- Policy Exclusion: Insurance coverage depended on having MFA in place. Despite warnings in 2022, Hamilton didn’t finish implementing MFA before the attack. Insurance cited this as grounds to deny the claim.
- Lack of Security Controls: Experts and city officials agreed: incomplete cyber hygiene, outdated systems, and poor adoption of basic requirements allowed the breach—and invalidated insurance protection.
The result: Hamilton taxpayers are left with the full cost and months of disruption.
