teamsters175.org Listed by incransom Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to target labor organizations and membership-based entities across the United States, often seeking leverage through the theft of internal records rather than solely encrypting systems. In this environment, the appearance of a union local on a threat actor’s leak site signals a potential compromise that can affect workers and their families long after the initial intrusion.

On January 29, 2025, the website teamsters175.org was listed by the ransomware group known as incransom. Public reporting indicates that internal files were exfiltrated during a ransomware attack. The number of people affected remains unknown, and further operational details have not been disclosed. The listing itself constitutes a claim by the group rather than independently verified confirmation of the full scope of the incident.

Inside the incident

According to available records, teamsters175.org was added to incransom’s listings on January 29, 2025. The sole description of exposed material is that internal files were allegedly exfiltrated in a ransomware attack. No public information has been released about the precise date of intrusion, the initial access method, the volume of data taken, or whether systems were encrypted in addition to the theft. The number of individuals potentially impacted is listed as unknown. Beyond the group’s claim on its leak site, no further technical indicators or official statements from the organization have been incorporated into the public record at this time.

Inside incransom

Incransom is a ransomware operation that follows a double-extortion model common among contemporary groups: after gaining access to a network, operators typically exfiltrate data before deploying encryption and then threaten to publish the stolen material if a ransom is not paid. The group maintains a leak site where it posts victim names and, in some cases, samples of purportedly stolen files to increase pressure. Like other actors in this category, incransom has historically focused on organizations that hold sensitive operational or personal records, using the prospect of public disclosure as leverage. Claims appearing on such sites are assertions by the threat actor and should be treated as unverified until corroborated by the victim organization or independent investigation. No additional statements by incransom specifically detailing the contents or volume of data from teamsters175.org beyond the listing itself have been recorded in the available facts.

Who is teamsters175.org?

Teamsters Local 175 is a labor union local affiliated with the International Brotherhood of Teamsters. Public materials associated with the site describe the local as proudly serving Teamster members and their families in West Virginia, Kentucky, Ohio, and Virginia since 1940. The organization engages in collective bargaining, contract negotiations, solidarity actions, and member support activities typical of a regional union local. Labor organizations of this type routinely maintain membership rosters, contact information, employment and benefit records, grievance files, and internal correspondence related to negotiations and workplace issues. A compromise of such an entity can therefore touch both active members and retirees whose personal and employment data may be held for administrative purposes. The consequential nature of a breach here stems from the trust members place in their local to safeguard information connected to their livelihoods and families.

What data was at risk

The facts state that internal files were exfiltrated in a ransomware attack. No more granular inventory of data types—such as specific categories of personal identifiers, financial records, or health-related information—has been disclosed. Organizations of this kind typically hold membership lists, addresses, phone numbers, Social Security numbers or other identifiers used for benefits administration, employment histories, and internal documents concerning contracts and negotiations. Because the exact contents remain unconfirmed, it is not possible to state with certainty which of these categories, if any, were among the files taken. Public detail is limited to the general characterization of “internal files.”

Why it matters

For members and their families, the primary risk is the potential misuse of personal and employment-related information that may have been present in the exfiltrated files. Even when precise data types are unknown, internal union records can enable identity theft, targeted phishing, or social-engineering attempts that reference genuine workplace details. For the organization itself, the incident raises operational concerns around member trust, the integrity of bargaining-related materials, and the administrative burden of responding to inquiries and potential regulatory obligations. Because the number of affected individuals is unknown and the full contents of the files have not been publicly itemized, the concrete impact on any given person cannot yet be quantified; the risk remains real but currently unmeasured.

Were you affected?

If you are a current or former member of Teamsters Local 175 or have reason to believe your information may have been held by the local, begin by monitoring financial accounts and credit reports for unexpected activity. Consider placing a fraud alert or credit freeze with the major credit bureaus and remain alert for phishing messages that reference union membership or workplace matters. Official notifications, if any are issued by the organization, should be followed carefully. Readers can also run a free exposure scan of their email address to check whether their information has already surfaced in known breach data sets. Public detail on this specific incident remains limited; any further confirmed information should come from the organization or law-enforcement sources rather than from the threat actor’s claims alone.
