Disclosure context

About nightspire

Nightspire is a ransomware group that first emerged in March 2025 and appears to be primarily financially motivated, having targeted over 215 victims in a relatively short operational timeframe. The group's origin and affiliations remain unclear due to limited public documentation from major cybersecurity organizations, though their targeting patterns suggest a broad opportunistic approach rather than nation-state backing. Based on available victim data, Nightspire appears to employ common ransomware attack vectors targeting organizations across multiple sectors, with a particular focus on manufacturing, technology, healthcare, and construction industries, while demonstrating a geographic preference for victims in the United States, India, Taiwan, France, and Hong Kong. The group's rapid victim acquisition rate since their March 2025 emergence suggests an active and potentially effective operational capability, though specific technical details about their attack methodology, encryption techniques, or extortion tactics have not been publicly documented by major threat intelligence firms. Given the recent emergence of this group and limited public reporting from established cybersecurity organizations like CISA, FBI, or Mandiant, Nightspire remains an active threat with insufficient public documentation to fully assess their operational sophistication or organizational structure. The group has been linked to 335 public disclosures across our corpus. First observed on a leak site on March 12, 2025; most recent post August 22, 2026. The operation is currently active.

If your organisation is affected

A listing by nightspire means Guy E******* & F*******, P.A 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.
  • Monitor for the data appearing on nightspire'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.
