Ransomware protection for Illinois — where an attack once closed a hospital
Illinois holds a sobering distinction: it was home to what's believed to be the first US hospital to close in part because of a ransomware attack. From the state government's exposure in the 2023 MOVEit campaign to the 2024 shutdown of a major Chicago children's hospital, Illinois has seen ransomware's full range. Immune keeps Illinois organizations running through an attack — detecting in seconds, containing before spread, and self-healing from immutable backups.
Immune adds the resilience layer Illinois organizations need — agentless coverage for the medical devices endpoint tools can't reach, and validated recovery — with controls that map to the state's strong PIPA and BIPA data-protection laws.
Why ransomware targets Illinois's industries
Illinois pairs a large manufacturing base with Chicago's role as a major financial and commodities center — derivatives exchanges, banks, and trading firms — and a significant agricultural economy downstate. This mix of high-value data and industrial systems gives ransomware groups a wide range of targets across the state.
The public sector has been hit at the highest level. In 2023, the State of Illinois was among the many governments caught in the CL0P group's mass exploitation of the MOVEit file-transfer software, exposing data held by state agencies — a demonstration that even state government is reachable through the software it relies on.

The Illinois healthcare landscape
Illinois healthcare is anchored by Chicago's renowned academic and children's hospitals and large regional systems, serving millions across the state. But Illinois also holds a grim milestone: St. Margaret's Health in Spring Valley became what's widely reported as the first US hospital to close, in part, because of a ransomware attack — a 2021 incident that crippled billing for months and contributed to the hospital ceasing operations in 2023.
The threat continued into recent years, with the 2024 attack on Lurie Children's Hospital in Chicago taking core systems offline for weeks. Together these show the existential stakes ransomware can pose to Illinois healthcare.
