National Safety Council Listed by medusa Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

For employees, partners, and others connected to the National Safety Council, the appearance of the organization on a ransomware group's leak site raises immediate questions about whether personal or organizational information has left its control. Public reporting indicates that internal files were taken in a ransomware attack, yet the number of people affected remains unknown and the precise contents of those files have not been detailed. That uncertainty itself is the practical stake: without confirmed scope, individuals must weigh the possibility that workplace records, contact details, or other sensitive material could surface or be misused.

The National Safety Council was listed by the Medusa ransomware group, according to reports dated March 17, 2025. The listing is a claim by the group that it holds data obtained through the attack; independent confirmation of the full extent of the incident has not been provided in the available facts.

Breaking down the breach

Public information states that the National Safety Council experienced a ransomware attack in which internal files were exfiltrated. The organization was subsequently listed by the Medusa ransomware group. The report date associated with this listing is March 17, 2025. No figure has been given for the number of people affected, and no further technical details—such as the initial access method, the duration of the intrusion, or the exact volume of data taken—have been disclosed in the available record. The facts describe the event only as a ransomware attack involving the theft of internal files, followed by the group's public listing of the victim.

Because the scale and precise timeline remain undisclosed, it is not possible to state how many individuals or which specific systems were involved. The listing itself functions as the group's assertion that it possesses the stolen material and may publish or auction it if its demands are unmet. No independent verification of that claim appears in the provided facts.

The group behind it: medusa

Medusa is a well-documented ransomware operation that has been active for several years. Like many modern ransomware groups, it typically follows a double-extortion model: encrypting systems while also copying data, then threatening to leak the stolen files on a dedicated leak site if a ransom is not paid. The group has previously claimed responsibility for attacks against a range of organizations across sectors, often posting sample files or full archives to pressure victims. Its listings are claims made by the operators and should be treated as such until corroborated by the victim organization or independent investigators.

In this case, Medusa has listed the National Safety Council. The facts do not record any specific statements the group made about the contents of the files beyond the general assertion that internal material was exfiltrated. Public knowledge of Medusa's tactics does not extend to inventing details unique to this incident; only the listing and the description of internal-file exfiltration are established in the record.

Who is National Safety Council?

The National Safety Council is a nonprofit, nongovernmental public-service organization founded in 1913. Its stated mission is to protect life and promote health in the United States. The corporate office is located at 1121 Spring Lake Drive, Itasca, Illinois, and the organization employs approximately 501 people. As a long-standing safety-advocacy body, it works with employers, communities, and government partners on injury prevention, workplace safety standards, and public-health initiatives.

Organizations of this type routinely handle employee records, membership or partner contact information, research data, training materials, and correspondence related to safety programs. A breach involving internal files is therefore consequential because it can affect both the people who work for or with the council and the integrity of the safety information the organization stewards. The facts do not assert any specific security failing; they simply record that the organization was listed after a ransomware attack that involved data exfiltration.

What was likely exposed

The available facts state only that internal files were exfiltrated in a ransomware attack. No inventory of file types, no count of records, and no confirmation of personal identifiers have been released. Because the exact contents remain undisclosed, it is not possible to declare with certainty what was taken.

Organizations similar to the National Safety Council commonly hold employee personnel files, payroll and benefits data, email archives, project documents, partner and donor lists, and research or program materials. Any of these categories could fall under the broad description of “internal files.” Until the organization or investigators publish a verified list, however, those possibilities remain unconfirmed. Readers should treat claims about specific data elements as speculative unless and until they are substantiated.

What's at stake

For individuals whose information may have been among the internal files, the primary risks are identity-related misuse, targeted phishing, and unauthorized contact. Even limited personal details—names, work emails, phone numbers, or employment records—can be combined with other publicly available data to craft convincing social-engineering attempts. For the organization itself, the stakes include operational disruption, potential regulatory scrutiny if personal data of employees or partners is involved, and reputational harm that can affect partnerships and public trust in its safety mission.

Because the number of people affected is unknown and the precise data types are unconfirmed, the practical impact cannot yet be quantified. The absence of those details does not eliminate risk; it simply means affected parties must proceed on the assumption that some internal material left the organization's control and could be misused.

What to do if you're exposed

If you are an employee, former employee, partner, or other individual connected to the National Safety Council, treat the possibility of exposure seriously until more information is released. Monitor financial and email accounts for unexpected activity, enable multi-factor authentication wherever available, and be cautious of unsolicited messages that reference the organization or safety programs. Consider placing a fraud alert with the major credit bureaus if you believe sensitive personal data may have been involved. Keep records of any suspicious contacts.

You can also run a free exposure scan of your email address to check whether it has already appeared in known breach data sets. That step provides an immediate, practical way to assess whether your information has surfaced publicly and helps prioritize further protective measures while official details remain limited.
