Disclosure context

About Nokoyawa

Nokoyawa is a ransomware group that emerged in December 2022, operating with primarily financial motivations and targeting organizations across multiple sectors including healthcare, non-profit, education, finance, and energy. The group has claimed at least 36 victims since its emergence, with attacks predominantly focused on the United States, Canada, United Kingdom, France, and the Philippines. While detailed technical analysis of Nokoyawa's operations remains limited in public reporting, the group appears to follow conventional ransomware tactics targeting critical infrastructure and essential services sectors. Their targeting of healthcare and educational institutions suggests they operate without the sector restrictions that some other ransomware groups have adopted. Notable campaigns include attacks across their preferred geographic regions, though specific high-profile incidents have not been extensively documented in public threat intelligence reporting from major security firms. As of current reporting, Nokoyawa appears to remain an active threat, though the group's relatively recent emergence means long-term operational patterns and potential law enforcement disruption efforts are still developing. The group has been linked to 36 public disclosures across our corpus. First observed on a leak site on December 9, 2022; most recent post August 4, 2023. The operation is currently inactive.
