Disclosure context

About Hiveleak

Hiveleak is a financially-motivated ransomware group that emerged in August 2021, conducting targeted attacks primarily against organizations in the United States, United Kingdom, Netherlands, Spain, and Germany with a focus on manufacturing, business services, information technology, healthcare, and education sectors. Limited public documentation exists regarding this group's specific country of origin or affiliations with other ransomware operations, though their targeting patterns and operational timeline suggest they operate as part of the broader ransomware ecosystem that proliferated during the 2021-2022 period. The group's attack methodology and technical capabilities remain largely undocumented in major threat intelligence reports from CISA, FBI, or leading security research firms, though their victim count of 208 organizations indicates sustained operational capability over their known active period. Notable campaigns and high-profile victims have not been extensively documented in public threat intelligence reporting, suggesting the group may have maintained a lower profile compared to major ransomware operations like Conti or LockBit during the same timeframe. The current operational status of Hiveleak remains unclear based on available public intelligence reporting. The group has been linked to 208 public disclosures across our corpus. First observed on a leak site on August 14, 2021; most recent post May 26, 2023. The operation is currently inactive.
