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 54 public disclosures across our corpus. First observed on a leak site on February 17, 2026; most recent post June 13, 2026. The operation is currently active.

If your organisation is affected

A listing by payload means Thai Solar Energy Public appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Monitor for the data appearing on payload's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
