high severity December 22, 2022 · 3 min read Unverified claim — what this is

COLORADO.EDU Listed by Clop Ransomware Group

If you are a customer of Colorado.Edu, here’s what is being claimed, and what it would mean for you.

Colorado.Edu was listed on Clop's leak site. Clop claims to have stolen internal data. This is the group's claim, not a confirmed finding.

COLORADO.EDU Listed by Clop Ransomware Group

On December 22, 2022, the University of Colorado Boulder appeared on the leak site operated by the Clop ransomware group. The listing states that internal files were exfiltrated during a ransomware attack on the university’s systems. The disclosure does not specify the number of people affected or list exact data types beyond claiming that internal files were taken.

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

Details in the Primary Listing

The Clop leak site entry for colorado.edu, accessible via the onion link indexed by ransomware.live, claims successful data theft from the University of Colorado Boulder. It presents the institution as a victim of a ransomware operation and gives a deadline for public release of the stolen material if demands are not met. The listing does not quantify records, name specific databases, or describe the content of the files. Public reporting on Clop’s past postings shows the group often posts proof-of-exfiltration samples and later releases full archives when victims refuse payment.

Why This Matters for You and Your Family

Universities hold enormous amounts of personal information about students, alumni, faculty, staff, and their families. Even without an exact count in the disclosure, a breach at colorado.edu can expose names, addresses, Social Security numbers, financial aid records, medical details from campus health services, and academic transcripts. If any member of your household attended, applied to, or worked with the University of Colorado Boulder, your family’s data may now sit in an attacker’s archive. Once exfiltrated files leave institutional control, they can circulate for years on dark-web forums and resale markets.

Credential reuse across personal and academic accounts turns this incident into a direct threat to everyday digital life. A password tied to a university email can unlock banking, shopping, and social-media profiles that contain far more sensitive details about you and your children.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
