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 252 public disclosures across our corpus. First observed on a leak site on December 7, 2025; most recent post May 12, 2026. The operation is currently active.
