Disclosure context

About Play

**Overview:** Play (also known as PlayCrypt) is a financially motivated ransomware group that emerged in late 2022, conducting targeted attacks against organizations across multiple sectors with a focus on financial extortion. **Origin & Affiliation:** The group's country of origin remains unclear based on public reporting, though they appear to operate independently rather than as a traditional ransomware-as-a-service model. **Attack Methodology:** Play ransomware operators typically gain initial access through compromised Remote Desktop Protocol (RDP) credentials and exploit valid accounts, then move laterally through networks using tools like Cobalt Strike before deploying their custom ransomware payload. The group employs double extortion tactics, stealing sensitive data before encryption and threatening to publish it on their leak site if ransom demands are not met. **Notable Campaigns:** According to CISA advisories, Play has targeted over 300 entities globally since its emergence, with significant impacts on critical infrastructure sectors including healthcare, education, and government services, though specific ransom amounts and individual victim details vary in public reporting. **Current Status:** Play remains an active threat as of 2024, continuing to target organizations primarily in North America and Europe according to ongoing security researcher observations and law enforcement warnings. The group has been linked to 1,311 public disclosures across our corpus. First observed on a leak site on November 26, 2022; most recent post June 30, 2026. The operation is currently active.

If your organisation is affected

A listing by Play means Kuhnline 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.
  • Report the incident to your national CERT, CERT-Bund (Germany), as required for your jurisdiction.
  • Monitor for the data appearing on Play'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.
