Disclosure context

About unsafe

The "unsafe" ransomware group is a relatively new threat actor that emerged in December 2022, operating with primarily financial motivations through ransomware deployment and extortion schemes. Based on limited public documentation, the group's origin and specific affiliations remain unclear, though their operational patterns suggest they function as an independent ransomware operation rather than a established Ransomware-as-a-Service model. With 14 documented victims since their emergence, the group has demonstrated a focused targeting approach, primarily concentrating their attacks on manufacturing organizations, transportation and logistics companies, and government entities across the United States, Switzerland, and France. Their attack methodology and specific technical capabilities have not been extensively documented by major security research organizations such as CISA, FBI, or Mandiant, limiting detailed analysis of their initial access vectors, encryption methods, or data exfiltration practices. No major high-profile campaigns or significant law enforcement actions have been publicly reported against this group, likely due to their relatively recent emergence and smaller scale of operations compared to more established ransomware families. Current intelligence suggests the group remains active as of available reporting, though their limited public footprint makes definitive status assessment challenging without additional threat intelligence sources. The group has been linked to 14 public disclosures across our corpus. First observed on a leak site on December 21, 2022; most recent post January 14, 2024. The operation is currently inactive.
