Disclosure context

About radar

Radar is an emerging ransomware group that first appeared in September 2025, operating with apparent financial motivations based on their targeting patterns across multiple sectors and countries. The group's origin and affiliations remain unclear due to limited public documentation from established threat intelligence sources, though their geographic targeting suggests a focus on English-speaking nations and select international markets. Based on available victim data, Radar appears to employ opportunistic targeting methods that have successfully compromised 23 organizations across diverse sectors including construction, financial services, transportation/logistics, and technology, with operations spanning the United States, United Kingdom, Australia, Kuwait, and other regions. The group's attack methodology, encryption techniques, and whether they employ double or triple extortion tactics have not been extensively documented by major threat intelligence firms or law enforcement agencies. No significant high-profile campaigns, major ransoms, or law enforcement disruption actions against Radar have been publicly reported by CISA, FBI, or established security research organizations. Given the group's recent emergence and limited public intelligence reporting, Radar's current operational status and long-term capabilities remain under assessment by the cybersecurity community. The group has been linked to 26 public disclosures across our corpus. First observed on a leak site on September 10, 2025; most recent post May 18, 2026. The operation is currently active.
