Disclosure context

About Quantum

Quantum is a ransomware group that emerged in September 2021, operating with primarily financial motivations and demonstrating a focus on high-value targets across English-speaking nations. The group's geographic targeting patterns and operational characteristics suggest possible connections to established ransomware ecosystems, though specific attribution or confirmed affiliations with other threat actors remain undocumented in public reporting. Quantum operators typically employ double extortion tactics, combining data encryption with the threat of public data exposure to maximize pressure on victims, and their campaigns have consistently targeted sectors with critical operational dependencies including business services, manufacturing, and information technology infrastructure. The group has maintained a relatively low public profile compared to other major ransomware operations, with their 68 documented victims representing a more selective approach to target acquisition rather than broad-scale campaigns. Despite limited public law enforcement reporting specifically focused on Quantum operations, the group's continued activity pattern suggests they remain an active threat as of recent observations, though comprehensive operational details remain scarce in publicly available threat intelligence reporting. The group has been linked to 68 public disclosures across our corpus. First observed on a leak site on September 9, 2021; most recent post December 9, 2022. The operation is currently inactive.
