Skira is a recently emerged ransomware group first observed in March 2025, operating with apparent financial motivations through targeted attacks against organizations primarily in the United States, India, Japan, and Turkey. The group's origin and potential affiliations remain unclear given their recent emergence, and there is insufficient public documentation to determine whether they operate as a Ransomware-as-a-Service model or as an independent entity. Based on their targeting pattern across diverse geographic regions and sectors including financial services, technology, manufacturing, and construction, the group appears to employ opportunistic attack vectors, though specific technical methodologies, encryption techniques, and data extortion tactics have not been publicly documented by major security researchers or government agencies. With only eight documented victims since their March 2025 emergence, Skira has not yet conducted any widely publicized high-profile campaigns or attracted significant law enforcement attention. The group appears to remain active as of current reporting, though comprehensive threat intelligence remains limited due to their recent operational timeline. The group has been linked to 8 public disclosures across our corpus. First observed on a leak site on March 6, 2025; most recent post November 18, 2025. The operation is currently active.

If your organisation is affected
A listing by skira means INNOVEX HOLDINGS CO., LTD 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, JPCERT/CC (Japan), as required for your jurisdiction.
- Monitor for the data appearing on skira'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.
