Genesis
Genesis is a ransomware group active since at least October 2025. It launched a dark web data leak site in October 2025 and was described in 2026 reporting as a newer/emerging ransomware actor. Reporting cited in the content states that Genesis malware steals data and locks systems, and that the group demands payment to destroy stolen data and restore infected systems. Separate reporting in the content also associates Genesis with credential access and underground market activity, including the sale or use of compromised enterprise access; in 2026, Genesis-linked activity was reported as contributing to healthcare intrusions by enabling initial access through stolen credentials, facilitating downstream ransomware and data theft operations. Genesis shows a strong US focus. One cited Q1 2026 assessment says 27 of 29 confirmed victims were in the United States (93.1%), with a notable emphasis on the healthcare sector (20.7%), and no documented affiliate program. The content repeatedly links Genesis to healthcare and healthcare-adjacent victims, including the National Association on Drug Abuse Programs (NADAP), Advanced Family Surgery Center (AFSC), and Community Health Action of Staten Island. In the NADAP case, Genesis claimed responsibility in March 2026, said it stole 2 TB of data including medical information and HR files, and listed the organization on its leak site. In the AFSC case, Genesis claimed it exfiltrated 100 GB of healthcare, personal, financial, and operational data and posted a file tree; reviewed sample files reportedly included PHI. In the Community Health Action of Staten Island case, Genesis added the organization to its leak site and claimed exfiltration of approximately 200,000 records, including sensitive personal and medical data. The content also states that Genesis had claimed 49 ransomware attacks in total at the time of one report, with seven attacks confirmed by targeted organizations. Additional cited victims or claimed victims include Upper Township and the local government of Hart, Michigan. Known alias information in the provided content is limited to the lowercase form "genesis"; no sub-groups are identified in the source material.
