Disclosure context

About netrunner

Based on the limited publicly available information, netrunner is a relatively new ransomware group that first emerged in April 2026 with documented attacks against at least six organizations. The group appears to be financially motivated, targeting a diverse range of sectors including healthcare, consumer services, telecommunications, manufacturing, and agriculture across multiple countries including Japan, the United States, Jordan, Italy, and South Korea. Due to the recent emergence of this group and limited public reporting from established threat intelligence sources, detailed information about their country of origin, operational affiliations, specific attack methodologies, encryption techniques, or whether they operate as a Ransomware-as-a-Service model remains undocumented by major cybersecurity organizations such as CISA, FBI, or Mandiant. The group's targeting pattern suggests opportunistic victim selection rather than geopolitically motivated attacks, given the broad geographic and sectoral distribution of their documented victims. No major high-profile campaigns or significant law enforcement actions against netrunner have been publicly reported by reputable security researchers at this time. Given the group's recent emergence in 2026, current activity status and operational capabilities require further monitoring and analysis by the cybersecurity community. The group has been linked to 14 public disclosures across our corpus. First observed on a leak site on April 3, 2026; most recent post October 3, 2026. The operation is currently active.

If your organisation is affected

A listing by netrunner means Precon Marine Inc 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 netrunner'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.
