What the group claims

Hunter was created by Antoine Finkelstein and François Grante in 2015. Freshly graduated, they saw the untapped potential of cold emails and wanted to address the challenges of prospecting and finding contact information. To achieve great success rate while complying with privacy regulations, they decided to use emails found on the public web. Email Hunter was born. Soon rebranded as Hunter, the tool quickly became a game-changer in business intelligence. Within weeks, it attracted thousands of users thanks to its user-friendly interface, handy browser extension, affordable pricing, and data accuracy. Unlike its peers, Hunter aimed not at large enterprises but at making cold emailing accessible to all. Over time, Hunter grew into a comprehensive email outreach platform, offering everything from finding contact information to sending cold emails. Antoine and François, with a focused team, continued to empower professionals with simple, powerful tools.-Personal information of employees and clients-Databse-Financial documents-Other files https://hunter.io/

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 159 public disclosures across our corpus. First observed on a leak site on April 29, 2024; most recent post May 31, 2026. The operation is currently active.
