Buttery (butterycompany.com) Listed by fog Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to dominate the cyber-threat landscape in 2025 by combining encryption with data theft and public leak-site postings, pressuring organisations to pay while exposing victims to secondary risks. Against that backdrop, the listing of Buttery (butterycompany.com) by the fog ransomware group, reported on 14 January 2025, adds another entry to the growing roster of claimed double-extortion incidents.

Public reporting indicates that fog claims to have exfiltrated 1.7 GB of internal files from the organisation. The number of people affected remains unknown, and independent confirmation of the intrusion or the precise contents has not been released. The episode matters because even limited internal data can enable further fraud, social engineering or competitive harm once it leaves an organisation’s control.

Breaking down the breach

According to the available record, Buttery (butterycompany.com) was listed by the fog ransomware group on or around 14 January 2025. The group asserts that it carried out a ransomware attack and exfiltrated 1.7 GB of internal files. No further technical details—such as the initial access vector, the duration of the intrusion, or whether systems were encrypted—have been disclosed in the public summary. The number of individuals whose information may have been involved is listed as unknown. Because the listing originates from the threat actor’s own site, it constitutes an unverified claim rather than a confirmed forensic finding.

Who is fog?

Fog is a ransomware operation that became publicly visible in 2024 and has since maintained an active leak site used for double-extortion campaigns. Like many contemporary groups, it typically gains access through common vectors such as compromised credentials or unpatched services, deploys ransomware to encrypt systems, and simultaneously steals data to increase leverage. Victims are then threatened with publication of the stolen material if a ransom is not paid. Fog has listed organisations across multiple sectors and geographies; its postings usually include a claimed data volume and a countdown before full release. In the present case the group claims to hold 1.7 GB of Buttery’s internal files; no additional statements attributed specifically to this victim beyond that listing appear in the public record.

About Buttery (butterycompany.com)

Buttery operates under the domain butterycompany.com. Publicly available detail about the organisation’s precise industry, size or geographic footprint is limited. Companies of this general commercial character commonly maintain internal repositories that include employee records, customer correspondence, financial documents, operational plans and proprietary materials. A breach of such material is consequential because it can disrupt day-to-day operations, expose confidential business relationships and create lasting trust issues with partners and clients, even when the full scope remains unconfirmed.

The information in question

The facts name the exposed material only as “internal files” amounting to 1.7 GB that were allegedly exfiltrated during a ransomware attack. No further breakdown—such as whether the files contain personal identifiers, financial data, intellectual property or other categories—has been disclosed. Organisations of this type typically hold a mix of employee information, client details, contracts and operational documents. Because the exact contents remain unconfirmed, it is not possible to state with certainty which specific data elements, if any, are in the hands of the threat actor.

What's at stake

For individuals whose information may be among the files, the principal risks are identity theft, targeted phishing and unsolicited contact that leverages any personal or professional details that surface. For the organisation itself, the stakes include potential regulatory scrutiny, contractual liabilities, reputational damage and the operational cost of investigation and remediation. Even a modest volume of internal files can supply attackers with enough context to craft convincing follow-on attacks against employees, suppliers or customers. Until the full nature of the material is verified, both the company and any potentially affected parties must treat the claim as a credible but unconfirmed exposure.

Were you affected?

If you have a past or present relationship with Buttery—whether as an employee, customer or partner—monitor financial statements and account activity for unusual transactions, and treat unexpected emails or calls that reference the company with caution. Enable multi-factor authentication on important accounts and consider placing fraud alerts with credit bureaus if you believe personal data may be involved. Readers can also run a free exposure scan of their email address to check whether that address has already appeared in known breach data sets; such a scan provides an early indication of wider exposure even when the precise contents of a single incident remain undisclosed.
