Disclosure context

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.

About the victim

AI dossier — public-source company profile

AbelZeta Pharma is a global cell therapy company focused on discovering, developing, and manufacturing T cell-based therapeutics, including CAR-T therapies, to address unmet medical needs in hematologic malignancies, inflammatory and immunological diseases, and solid tumors. The company operates globally and is headquartered in the United States (area code +1 240, suggesting Maryland/DC area). It is an independent biopharmaceutical firm, distinct from Johnson & Johnson despite the group's misleading post framing.

Industry: Biotechnology & Cell Therapy (Oncology & Immunology)

Attack summary

Severity: high — Data has been published (data_published status) by the threat actor against a biopharmaceutical company with proprietary CAR-T and cell therapy research; exfiltration of clinical, research, or patient-adjacent data from a pharma/biotech firm constitutes significant sensitive business and potentially regulated data exposure. The misleading J&J framing in the post does not reduce the risk to AbelZeta's actual data.

The Spacebears ransomware group claims to have compromised AbelZeta Pharma and has published data (disclosed status: data_published), though the leak post text describes Johnson & Johnson Innovative Medicine rather than AbelZeta, suggesting possible mislabeling or deliberate obfuscation. The nature of exfiltrated data and encryption status are not explicitly described in the post excerpt.
