DARTMOUTH.EDU Listed by clop Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Dartmouth.edu was listed today by the Clop ransomware group after internal files were exfiltrated in a ransomware attack. An undisclosed number of individuals may have been affected; anyone connected to the institution should check official notices and change passwords or enable additional security steps if advised.
What happened
The only confirmed public information is the listing of DARTMOUTH.EDU on a site associated with the Clop group on November 13, 2025. The group claims to have exfiltrated internal files in a ransomware attack. No official statement from the organization has confirmed the intrusion, and details such as the date of any compromise, the volume of data taken, or the method of access remain undisclosed.
The group behind it: clop
Clop is a ransomware operation that has conducted multiple campaigns since at least 2019. It is known for encrypting systems and then threatening to publish stolen data unless a ransom is paid. The group maintains a leak site where it lists organizations it claims to have targeted. Such listings are unverified claims until corroborated by the affected organization or independent investigation.
DARTMOUTH.EDU and its sector
DARTMOUTH.EDU is the primary internet domain for Dartmouth College, a private research university. Institutions in higher education maintain large volumes of records related to enrollment, employment, financial aid, research, and institutional operations. These records are subject to regulatory requirements around data protection in the United States.
The information in question
The listing refers to internal files exfiltrated during a ransomware attack. The precise categories of data involved have not been disclosed. Organizations of this type routinely store names, contact details, academic records, financial information, and employment documents, but it is not confirmed whether any of these specific types were taken in this case.
What's at stake
For individuals, exposure of internal files can lead to misuse of personal identifiers for fraud or targeted scams. For the institution, the event may prompt regulatory review, increased security costs, and loss of trust among students and staff. The absence of Reported Details means the actual impact cannot yet be measured.
If your data was in this claimed breach
Monitor financial accounts and academic portals for unusual activity. Enable multi-factor authentication on any associated services and review privacy settings. Individuals can also run a free exposure scan of their email address against known breach data to check for appearances in previously published records.

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.
