Intensive Care On-Line Network , Inc Listed by avaddon Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Intensive Care On-Line Network , Inc Listed by avaddon Ransomware Group (reported September 9, 2021) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
In September 2021, Intensive Care On-Line Network, Inc appeared on a ransomware group's data-leak site, an event that reflects the broader pattern of targeted attacks against healthcare-adjacent organizations during that period. Public records show only that the group listed the company and asserted possession of internal files; no independent confirmation of the volume or contents has been released, and the number of individuals potentially affected remains unknown.
Such listings matter because they place pressure on affected entities to respond while leaving patients, staff, and partners with limited information about what, if any, records may have left the organization's control. The incident fits into an established tactic in which operators combine encryption with the threat of disclosure to prompt payment.
Breaking down the breach
The only confirmed public detail is the listing itself, reported on 9 September 2021. The ransomware group placed Intensive Care On-Line Network, Inc on its leak site and stated that internal files had been removed. No figure for records, files, or individuals has been published, and the organization has not released a statement detailing the intrusion vector, duration, or scope of access. Whether encryption occurred alongside the claimed exfiltration is also undisclosed.
Who is avaddon?
Avaddon operated as a ransomware-as-a-service group that relied on double-extortion methods: encrypting systems and separately threatening to publish stolen material. The group maintained a public leak site where it listed victims that had not paid demanded ransoms. Its activity peaked in 2020 and 2021 before the operators later discontinued the operation. Listings on the site constituted claims by the group rather than independently verified events.
Who is Intensive Care On-Line Network , Inc?
Intensive Care On-Line Network, Inc functions in the healthcare technology sector, providing online services and network infrastructure that support intensive-care operations. Organizations of this type routinely process clinical records, staff credentials, operational logs, and communications with hospitals or care providers. A compromise at such an entity can affect both the continuity of care systems and the confidentiality of information that patients and clinicians expect to remain protected.
The information in question
The listing described only “internal files” without further enumeration. Exact data categories have not been confirmed by any public source. Entities in this sector commonly hold patient identifiers, treatment notes, diagnostic results, billing information, and internal administrative documents; however, whether any of these categories were present in the claimed exfiltration cannot be established from available information.
Why it matters
Healthcare-related data carries long-term sensitivity because medical details cannot be changed and may influence insurance, employment, or future care decisions. When an organization’s internal files are claimed to have been removed, downstream risks include unauthorized access to operational procedures and potential misuse of any personal information that those files contained. For the organization, the episode adds operational disruption and regulatory scrutiny even when the precise scale of exposure stays unknown.
If your data was in this claimed breach
Individuals connected to the organization should begin with basic protective steps while awaiting any official notification.

- Review account statements and credit reports for unusual activity.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
