Cedar Grove Composting Listed by conti Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Cedar Grove Composting Listed by conti Ransomware Group (reported September 24, 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.
Inside the incident
Cedar Grove Composting was listed on the Conti ransomware leak site on September 24, 2021. The group stated that it had exfiltrated internal files during a ransomware attack. No information has been released about the number of records involved, the precise date of the intrusion, or the method used to gain access. Public reporting has not confirmed whether any of the claimed data was subsequently published or sold.
Who is conti?
Conti is a ransomware operation that emerged publicly around 2020 and became known for encrypting victim systems and threatening to publish stolen data if ransom demands were not met. The group has targeted organizations across multiple sectors and has used dedicated leak sites to pressure victims. Its listings represent claims made by the operators rather than independently verified events.
Who is Cedar Grove Composting?
Cedar Grove Composting operates in the organic-waste processing sector, converting food scraps and yard waste into compost and soil products. Companies of this type maintain records on employees, commercial customers, delivery schedules, and regulatory compliance. A breach at such a firm can therefore involve both personal identifiers and operational details that are not otherwise public.
The information in question
The Conti listing described the material as internal files taken during a ransomware attack. No inventory of specific data fields has been published. Organizations in this sector commonly store employee contact and payroll information, customer account details, and records of business transactions, yet the exact contents of any files claimed in this case remain unconfirmed.
Why it matters
Exposure of internal files can lead to follow-on fraud attempts, phishing campaigns, or misuse of personal information belonging to employees and customers. For the organization, the incident adds costs related to investigation, potential regulatory review, and restoration of systems. Because the scale of the data remains undisclosed, individuals cannot yet assess their personal level of exposure.
If your data was in this claimed breach
Monitor accounts for unusual activity and consider placing fraud alerts with credit agencies if employment or financial records may have been involved. Change passwords for any services tied to the organization and enable multi-factor authentication where available. Readers can run a free exposure scan of their email address against known breach data to check for appearances in public listings.

Publicly posted by conti — unverified claim, pending independent verification
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.
