Attack summary

Severity: high — Data has been confirmed published by the threat actor, indicating exfiltration of significant business data including tenant PII, real estate records, and potentially financial/contractual documents across a multi-division holding company. Publication without a stated ransom suggests the exfiltration phase is complete.

The ThreeAM ransomware group claims to have attacked Bun Holding and has published data (disclosed status: data_published), suggesting both exfiltration and likely encryption occurred. No specific ransom amount or data volume was stated in the leak post.

Disclosure context

About Threeam

Threeam is a financially motivated ransomware group that emerged in September 2023, operating as a relatively new player in the ransomware ecosystem with 64 documented victims across multiple countries and sectors. The group's origin and potential affiliations remain unclear due to limited public documentation from major security agencies, though their targeting patterns suggest a broad opportunistic approach rather than nation-state backing. Based on available victim data, Threeam appears to employ common initial access vectors targeting organizations across business services, healthcare, manufacturing, and technology sectors, with the United States, United Kingdom, Australia, France, and Brazil representing their primary geographic focus areas. While specific technical details about their encryption methods and extortion tactics have not been extensively documented by major threat intelligence firms, their emergence in late 2023 and victim count suggests they have established operational capabilities within the competitive ransomware landscape. The group's current operational status remains active based on the recency of their emergence, though detailed law enforcement actions or disruption efforts have not been publicly reported by CISA, FBI, or other major security organizations. The group has been linked to 88 public disclosures across our corpus. First observed on a leak site on September 14, 2023; most recent post July 18, 2026. The operation is currently inactive.

If your organisation is affected

A listing by Threeam means bun.nl appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Report the incident to your national CERT, NCSC-NL (Netherlands), as required for your jurisdiction.
Monitor for the data appearing on Threeam's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable.
