About kryptos

Kryptos is a recently emerged ransomware group first observed in October 2025, operating with apparent financial motivations based on their targeting patterns across multiple countries and sectors. The group's origin and potential affiliations remain unclear due to limited public documentation from established security researchers, though their geographic targeting spanning the United States, Australia, India, Sri Lanka, and Canada suggests either broad opportunistic attacks or potential coordination across different threat actors. With only five documented victims to date, specific details about Kryptos's attack methodology, initial access vectors, and technical capabilities have not been extensively analyzed or published by major cybersecurity firms or government agencies. The group has demonstrated a preference for targeting public sector and educational institutions, which aligns with common ransomware tactics of pursuing organizations with potentially weaker security postures and critical operational requirements that may increase payment likelihood. Given the group's recent emergence and limited victim count, comprehensive threat intelligence regarding their specific tools, techniques, procedures, and notable campaigns remains insufficient for detailed characterization. Kryptos appears to remain active as of late 2025, though their operational tempo and long-term persistence cannot be definitively assessed given the brief observation period and sparse public reporting. The group has been linked to 5 public disclosures across our corpus. First observed on a leak site on October 8, 2025; most recent post November 6, 2025. The operation is currently inactive.
