Disclosure context

About lockbit5

Based on the provided data, LockBit5 appears to be a recently emerged ransomware operation first observed in December 2025, representing what may be a new iteration or rebrand within the LockBit ransomware ecosystem, with primary financial motivations evidenced by their targeting of high-value sectors. Given the LockBit naming convention and the timing of emergence, this group likely operates from Eastern Europe or Russia and may represent either a continuation of previous LockBit operations or a new affiliate group leveraging the established LockBit brand, though specific organizational details remain undocumented by major security agencies. While detailed attack methodologies have not been publicly documented by CISA, FBI, or major security researchers, the group's targeting pattern across 157 victims suggests a broad-spectrum approach focusing on technology, manufacturing, healthcare, and transportation sectors primarily in the United States, Brazil, Germany, Italy, and Mexico. Due to the group's recent emergence in December 2025, there are no publicly documented notable campaigns or major incidents reported by established threat intelligence sources, though the victim count indicates active operations. The group appears to be currently active based on the recent first observation date, though comprehensive analysis from major security agencies has not yet been published given the short timeframe since emergence. The group has been linked to 370 public disclosures across our corpus. First observed on a leak site on December 7, 2025; most recent post September 29, 2026. The operation is currently active.

If your organisation is affected

A listing by lockbit5 means spg.co.kr 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, KrCERT/CC (South Korea), as required for your jurisdiction.
  • Monitor for the data appearing on lockbit5'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.
