Disclosure context

About payload

Based on the limited publicly available information, Payload is an emerging ransomware group first observed in February 2026 with a primarily financial motivation, having targeted 19 documented victims across multiple countries and sectors. The group's origin and affiliations remain unclear, with no documented evidence of their operational structure, country of origin, or whether they operate as a Ransomware-as-a-Service model or independent entity. Their attack methodology, encryption techniques, and specific tools used have not been publicly documented by major cybersecurity firms or law enforcement agencies. The group has demonstrated a diverse targeting approach, focusing primarily on victims in the Philippines, United States, United Kingdom, Mexico, and Dominican Republic, with particular emphasis on manufacturing, agriculture and food production, transportation/logistics, and telecommunication sectors, though the specific campaigns and ransom demands remain undisclosed in public threat intelligence reports. Given the group's recent emergence and limited public documentation, Payload appears to be currently active but remains a relatively obscure threat actor with insufficient publicly available data to establish comprehensive intelligence assessments from major cybersecurity organizations or law enforcement agencies. The group has been linked to 46 public disclosures across our corpus. First observed on a leak site on February 17, 2026; most recent post May 19, 2026. The operation is currently active.
