What the group claims

The data contains really sensitive information from 4 PV projects looking for investment/financing of Hanwha. We extracted around 12GB of highly sensitive information relating to the following projects: - Bonanza Peak (3GB) - Boulder Solar III (0.7GB) - Obreron Portfolio (4.8GB) - Project Sprout (3.7GB) In the data we found highly sensitive information including: - PPAs - Financial models - Interconnection agreements - Engineering designs of the assets - Personal identifiable information - Sensitive reports, budgets, financial information Reach out to prevent the leak. Cost of litigation from counterparties for breach of confidentiality is way higher. Commercially, good luck negotiating after your practices and contracts are leak. Good luck looking for financing/investment for these assets with the data leaked. [Size: 11.7 GB | Sector: Energy]

Disclosure context

About emperador

Emperador is a ransomware group first observed in August 2026 with an apparent financial motivation, though its limited operational history makes comprehensive attribution difficult at this time. Based on available data, the group has recorded at least one confirmed victim, with targeting concentrated in the Philippines and a demonstrated focus on the Government and Defense sector, suggesting either opportunistic targeting or a deliberate interest in sensitive public-sector data. Specific details regarding initial access vectors, encryption methodologies, and tooling have not been publicly documented by CISA, the FBI, Mandiant, or other reputable threat intelligence sources as of this profile's compilation, and no affiliation with known ransomware-as-a-service ecosystems or established threat actor clusters has been formally established. No notable high-profile campaigns, record ransom demands, or law enforcement actions have been publicly attributed to this group, which is consistent with its nascent operational timeline and minimal victim count. Given its very recent emergence and limited observed activity, Emperador should be considered an emerging and uncharacterized threat requiring continued monitoring, particularly by organizations operating within Philippine government and defense environments. The group has been linked to 18 public disclosures across our corpus. First observed on a leak site on August 12, 2026; most recent post August 31, 2026. The operation is currently active.

If your organisation is affected

A listing by emperador means Hanwha Renewables 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, KrCERT/CC (South Korea), as required for your jurisdiction.
Monitor for the data appearing on emperador'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. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
