Disclosure context

About cmdorganization

Based on the limited available information, cmdorganization is an obscure ransomware group first observed in May 2026 with only three documented victims to date, suggesting either a newly emerged threat actor or a small-scale operation with primarily financial motivations. The group's targeting pattern shows a geographic focus on Canada, the United States, and Italy, with a sectoral preference for healthcare and construction industries, though the limited victim count makes it difficult to establish definitive targeting criteria. Due to the recent emergence and low victim count, there is insufficient publicly documented information from major cybersecurity firms or law enforcement agencies regarding their specific attack methodologies, encryption techniques, or operational structure. No notable high-profile campaigns or significant ransoms have been publicly reported for this group, likely due to their limited operational scope and recent emergence. Current intelligence suggests the group remains active but operates at a relatively small scale compared to established ransomware families. The group has been linked to 12 public disclosures across our corpus. First observed on a leak site on May 2, 2026; most recent post May 18, 2026. The operation is currently active.
