Disclosure context

About Knight

Knight is a relatively new ransomware group that emerged in September 2023, operating with primarily financial motivations and demonstrating a focus on targeting critical infrastructure and high-value sectors. The group's origin and specific affiliations remain largely undocumented in public threat intelligence reports, though their operational patterns suggest they operate as an independent entity rather than a established ransomware-as-a-service model. With 48 known victims since their emergence, Knight has shown a preference for targeting organizations across the United States, Brazil, Italy, Spain, and Germany, with particular focus on healthcare, manufacturing, media, and government sectors. Their attack methodology and specific technical capabilities have not been extensively documented by major security firms, though their targeting of healthcare and government entities suggests they employ effective initial access techniques and likely utilize double extortion tactics common among contemporary ransomware groups. While specific notable campaigns have not been widely publicized by CISA, FBI, or major security researchers, the group's consistent activity across multiple countries and high-value sectors indicates sustained operational capability. Knight appears to remain active as of current reporting, though detailed technical analysis and specific law enforcement actions against the group have not been publicly documented by authoritative sources. The group has been linked to 48 public disclosures across our corpus. First observed on a leak site on September 6, 2023; most recent post February 12, 2024. The operation is currently inactive.

If your organisation is affected

A listing by Knight means Studio D.EL.LA. SRL 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, CSIRT Italia (Italy), as required for your jurisdiction.
  • Monitor for the data appearing on Knight'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.
