Summary

Ridgecrest Regional Hospital logo

Ridgecrest Regional Hospital in California confirmed a Nov. 9, 2026, cyber incident and took systems offline amid computer and telephone outages. Hospital phone service returned, while its pharmacy reported a contemporaneous prescription-processing and payment outage, followed by partial recovery and a backlog. ScarlettGroup claims patient, employee and financial records and displays apparent surveillance images and a countdown; attribution, data theft and broader recovery remain unconfirmed.

Key facts

Timeline

  • Incident start:
    ? Earliest known or assessed start of malicious activity or incident activity.
  • First public signal:
    ? Earliest public indication of an outage, disruption, closure or other observable incident impact. The signal does not need to mention cybersecurity.
  • First public cyber evidence:
    ? Earliest credible public information connecting the incident or disruption to malicious cyber activity.
  • Official cyber disclosure:
    ? First official acknowledgment by the affected organization or an authoritative public body that the incident was cyber-related.
  • Last impact seen:
    ? Latest public indication that disruption, degraded operations, recovery work or unresolved impact was still ongoing.

Incident characteristics

Assessments

Attack mechanisms

  • Unknown cyber mechanism

    The incident is confirmed to be cyber-related, but the specific attack mechanism is unknown.

Data impacts

  • Unknown data impact

    The incident is cyber-related, but available evidence does not establish whether or how data was affected.

Operational impacts

  • Phone service disruption

    Telephone, voice-over-IP, call-center, or related voice communication services were unavailable or materially impaired.

  • Internal systems unavailable

    Internal business, administrative, operational, or staff-facing systems were unavailable.

  • Payment processing disruption

    The organization could not process, receive, issue, reconcile, or record payments normally.

  • Healthcare operations disrupted

    Clinical, diagnostic, pharmacy, patient-care, medical-record, or other healthcare operations were materially affected.

  • Backlog created

    The disruption caused an accumulation of unprocessed requests, cases, orders, records, appointments, or other work.

  • Alternate service channel required

    The organization redirected users to a different website, office, telephone number, email address, provider, or service channel.

Extortion indicators

  • Leak-site listing

    The victim was listed on a threat actor or ransomware data-leak site as an alleged target or nonpaying victim.

  • Countdown or payment deadline

    The actor imposed a deadline or public countdown before increasing the demand, publishing data, deleting keys, or taking another threatened action.

Incident narrative

Analyst assessment

Ridgecrest Regional Hospital confirmed a cyber incident on Nov. 9, 2026, and said it proactively took systems offline to investigate. The Ridgecrest Daily Independent published the hospital’s statement amid a phone and computer outage. The acknowledgment establishes cyber involvement, while the initial access method and affected technical environment remain unknown.

ScarlettGroup listed the hospital’s rrh.org domain and claimed to possess patient, employee, payroll, clinical and financial records. In our Nov. 10 reporting, we documented the listing’s claimed record categories, apparent surveillance images and countdown labeled “Negotiation Deadline.” The claims and the images’ authenticity have not been independently verified, and the countdown does not establish that the hospital is negotiating. The tracker-derived claim report separately records discovery on Nov. 9; discovery does not establish the original publication time.

Operational significance

The confirmed effects include loss of normal telephone access and disruption to computer systems. In an outage update, the hospital supplied an alternate contact number and said calls could not be transferred internally. This documents degraded communications with departments and clinics; it does not establish canceled appointments, emergency department closure, ambulance diversion or loss of clinical records.

The hospital system’s Center Professional Pharmacy reported an internet outage that halted new prescription and refill processing and electronic payments. Customers notified that prescriptions were ready might still collect them using cash. The pharmacy did not identify the outage’s cause, so its notice does not independently establish the technical connection to the hospital’s cyber incident.

The affected organization is a private nonprofit hospital and integrated health system based in Ridgecrest, Kern County. Public communications about a system outage are operationally significant for access to hospital staff, but the available notices do not establish interruption to inpatient or emergency care, or effects at every affiliated clinic.

Current status

The hospital subsequently announced that its phone lines were restored and departments and clinics could again be reached through their usual numbers. That is affirmative partial recovery. The announcement addresses telephone access rather than confirming restoration of every computer system. As of Nov. 10, the hospital’s website still displayed an undated telephone and computer outage banner with the earlier alternate contact number. The banner’s lack of a timestamp leaves it unclear whether it reflected current conditions; it does not establish a renewed phone outage.

In a Nov. 9 afternoon update, the pharmacy said its software and electronic payments were working again, but phones remained down and staff were “WAY behind.” No estimate was given for clearing the prescription backlog. The hospital’s separate telephone-restoration announcement does not independently establish when the pharmacy’s remaining phone issues ended.

DysruptionHub assesses the incident as presumed active because a system shutdown was documented Nov. 9 and the subsequent recovery notice specifically restores phones. The pharmacy’s same-day backlog and limited recovery notices leave the remaining scope and duration of computer-system disruption unresolved. One day had elapsed since the last dated operational observation; this assessment does not imply continuing attacker access.

Confidence and uncertainty

Confidence is high that the hospital experienced a cyber incident with computer and telephone disruption because of its statement and official service notices. Ransomware involvement and ScarlettGroup attribution remain low confidence. The listing provides a detailed allegation and observable countdown pressure, not independent confirmation of a compromise mechanism or the claimant’s responsibility. Patient-data theft, surveillance access and any ransom demand received by the hospital remain unconfirmed.

Analytic gaps

The public record does not establish the intrusion vector, malware, encryption scope, clinical-system effects, data-access findings, the authenticity or capture dates of the apparent surveillance images, negotiations or method of restoration. A broader recovery statement and investigative findings are needed to determine the full operational duration and whether the claim corresponds to the hospital’s confirmed incident.

Claim details

ScarlettGroup claimed to possess patient, employee, payroll, clinical and financial records from Ridgecrest Regional Hospital and listed its rrh.org domain on its extortion site. The indexed claim was discovered Nov. 9, 2026; the listing also displays a Nov. 9 date label, which does not establish its original publication time.

The alleged material includes patient identity and account records, emergency contacts, allergy and consent records, clinical and release-of-information archives, payroll and benefits information, wage histories, HR files, billing and legal documents, database tables and email. The listing also displays apparent surveillance images of interior work areas. Neither the claimed access nor the images’ authenticity, location or capture dates has been independently verified.

A Nov. 10 capture shows a countdown labeled “Negotiation Deadline,” with five days and about 21 hours remaining, pointing to approximately Nov. 16. That estimate depends on capture timing and an unchanged timer; the label does not establish that the hospital is negotiating. Our reporting documents the claim alongside the hospital’s acknowledged cyber incident and operational disruption.

The hospital has not attributed the incident to ScarlettGroup or confirmed ransomware or the theft of patient information. The public listing and its allegations do not establish that the group caused the system outage.
