About Spacebears

Spacebears is a recently emerged ransomware group first observed in April 2024, operating with apparent financial motivations and demonstrating a broad targeting approach across multiple sectors and geographic regions. The group's origin and potential affiliations remain unclear due to limited public documentation from established threat intelligence sources, though their targeting pattern suggests a professional operation focused on maximizing financial returns rather than geopolitical objectives. With 117 known victims since their emergence, Spacebears has shown particular focus on organizations in the United States, Germany, Spain, Italy, and Canada, with their attacks primarily affecting technology, healthcare, manufacturing, and business services sectors, indicating they likely employ opportunistic targeting rather than sector-specific specialization. Their attack methodology, initial access vectors, and specific technical capabilities have not been extensively documented in public reporting from major cybersecurity firms or law enforcement agencies, limiting detailed analysis of their operational procedures and tools. Due to the group's recent emergence and limited public intelligence reporting, notable high-profile campaigns and specific victim details remain largely undocumented in established threat intelligence channels. The group's current operational status appears active given their recent emergence timeline, though comprehensive analysis is constrained by the lack of detailed public reporting from authoritative cybersecurity sources. The group has been linked to 147 public disclosures across our corpus. First observed on a leak site on April 29, 2024; most recent post May 13, 2026. The operation is currently active.
