Disclosure context

About payoutsking

PayoutsKing is a recently emerged ransomware group first observed in July 2025, operating with apparent financial motivations and demonstrating broad geographic and sectoral targeting capabilities. With limited public documentation available from major threat intelligence sources, the group's origin and affiliations remain unclear, though their targeting pattern suggests a professional ransomware operation rather than opportunistic attacks. Based on available victim data, PayoutsKing has compromised approximately 60 organizations across multiple sectors, with primary focus on the United States, Germany, United Kingdom, France, and Spain, targeting manufacturing, healthcare, technology, and construction industries alongside various other sectors. The group's attack methodology, encryption techniques, and whether they employ double or triple extortion tactics have not been publicly detailed by established security researchers or government agencies. Given the group's recent emergence in July 2025, there are no widely reported major campaigns or high-profile incidents documented by reputable sources such as CISA, FBI, or Mandiant at this time. PayoutsKing appears to remain active as of current reporting, though comprehensive threat intelligence profiles from established security firms have not yet been published due to the group's recent emergence. The group has been linked to 100 public disclosures across our corpus. First observed on a leak site on July 7, 2025; most recent post May 13, 2026. The operation is currently active.

If your organisation is affected

A listing by payoutsking means Vereinigte-stadtwerke 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 payoutsking'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.
