Disclosure context

About aurora

Aurora is a recently emerged ransomware group first observed in April 2026, operating with apparent financial motivations through targeted attacks across multiple sectors. Given its recent emergence, limited public documentation exists regarding the group's specific country of origin or affiliations with established ransomware operations, though its targeting patterns suggest a professional operation potentially operating as an independent entity rather than a known Ransomware-as-a-Service model. The group has demonstrated a preference for attacking business-critical sectors including business services, consumer services, manufacturing, healthcare, and financial services, with documented attacks spanning the United States, Canada, the Maldives, and Great Britain, though specific initial access vectors and technical methodologies remain undocumented by major threat intelligence firms. With only seven known victims documented since April 2026, Aurora represents a relatively small-scale operation compared to established ransomware families, though its cross-sector targeting approach and international victim scope indicate deliberate selection criteria rather than opportunistic attacks. The group remains active as of current reporting, though the limited victim count and recent emergence suggest either a highly selective targeting approach or a nascent operation still developing its operational capabilities. The group has been linked to 21 public disclosures across our corpus. First observed on a leak site on April 29, 2026; most recent post June 30, 2026. The operation is currently active.

If your organisation is affected

A listing by aurora means NTP B.V. Civil Engineering Construction 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 aurora'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.
