Full breach record for OSF HEALTHCARE SYSTEM

Regulator's decision — not a breach notification

This record is a regulator's decision, not the organisation's own breach notice. Breach-notification fields (discovery date, notification clock) are structurally absent — what this source establishes is the outcome and the provisions the decision cites.

HHS OCR settled a ransomware investigation with OSF Healthcare System regarding a 2021 breach affecting 53,907 patients. OSF agreed to pay $552,250 and implement a Corrective Action Plan addressing risk analysis, risk management, and notification failures.

No linked breach filing · watching

Compliance clocks stay unassessable until a breach filing is linked. This record is the regulator's action, not a breach notice. Dashed segments fill in automatically when corroboration arrives.

Evidence ladder

Leak-site claim

Attacker assertion only. Establishes: claim date, group, alleged victim.

Press / market report

Unlocks: incident narrative, operational impact. Still no compliance clock.

State AG / regulator filingThis record

Unlocks: discovery date, data types, affected count, compliance clock.

SEC 8-K / victim statement

Unlocks: materiality, stated response, full audit trail. Ceiling removed.

Source ceiling

  • instrument + outcome
  • amount as filed (USD)
  • CFR provisions
  • the breach it recites
  • discovery date
  • notification clock

The dates the agreement recites belong to the underlying breach, years earlier, and are kept as evidence of WHICH breach rather than as this record’s timeline.
