Play Ransomware Claims Attacks on Three US Companies

Originally published on CyberNetSec.

Executive Summary

The prolific Play ransomware group, also known as PlayCrypt, demonstrated a high level of activity on August 1, 2026, by adding at least three U.S.-based companies to its public data leak site. The victims span multiple industries and include Cambridge Management (property management), The Butcher Brothers (retail), and Sigma Plastics Group (manufacturing). In each case, the group claims to have exfiltrated internal company files and is threatening to publish the data if a ransom is not paid. None of the named companies have publicly confirmed the attacks.

Threat Overview

  • Threat Actor: Play (PlayCrypt)
  • Victims: Cambridge Management, The Butcher Brothers, Sigma Plastics Group
  • Claim: Ransomware deployment and data exfiltration.
  • Status: Unconfirmed by the victims.

Play ransomware has been active since mid-2022 and is known for its speed and efficiency in compromising networks. The group is a prominent double-extortion operator, meaning they steal data (T1041 - Exfiltration Over C2 Channel) before encrypting systems (T1486 - Data Encrypted for Impact). Their typical initial access vectors include the exploitation of unpatched vulnerabilities in public-facing infrastructure (e.g., Fortinet VPNs) and the use of compromised Remote Desktop Protocol (RDP) credentials.

Technical Analysis

Play ransomware's TTPs are well-documented. Once inside a network, they are known to:

  • Use legitimate system tools (AdFind, net, etc.) for network reconnaissance to identify high-value targets. (T1018 - Remote System Discovery)
  • Employ tools like Mimikatz to dump credentials and escalate privileges. (T1003 - OS Credential Dumping)
  • Move laterally across the network using RDP, PsExec, or WMI.
  • Exfiltrate large amounts of data to cloud storage providers before deploying the final encryption payload. The group's ability to target and list three separate companies in a single day indicates a well-resourced and organized operation, likely leveraging a Ransomware-as-a-Service (RaaS) model with multiple affiliates.

Impact Assessment

The collective impact of these three incidents, if confirmed, demonstrates the broad threat that ransomware poses to the U.S. economy. The targeting of diverse sectors—property management, retail, and manufacturing—shows that no industry is immune. For each company, a successful attack would result in significant business disruption, financial costs for remediation and recovery, and potential data breach notification requirements. The exfiltration of data from a manufacturer like Sigma Plastics could expose valuable intellectual property and trade secrets.

Cyber Observables — Hunting Hints

To hunt for Play ransomware activity, security teams should look for:

Type Value Description
File Name AdFind.exe A legitimate Active Directory query tool often dropped by Play affiliates for reconnaissance.
Command Line Pattern schtasks.exe /Create /SC ONLOGON Play has been observed using scheduled tasks to establish persistence.
Network Traffic Pattern Outbound SMB (TCP/445) traffic to unexpected internal systems. Could indicate lateral movement attempts.
File Extension .play The file extension appended to encrypted files by the Play ransomware.

Detection & Response

  1. Vulnerability Management: Proactively scan for and patch vulnerabilities known to be exploited by Play, such as those in Fortinet and other VPN appliances. This is a key part of Exploit Protection (M1050).
  2. EDR and Behavioral Analysis: Deploy an EDR solution capable of detecting the specific tools and techniques used by Play, such as the execution of AdFind or attempts to dump LSASS memory. D3FEND's Process Analysis (D3-PA) is critical.
  3. Lateral Movement Detection: Monitor for anomalous RDP and SMB connections between workstations and servers. Create alerts for accounts logging into an abnormally high number of systems.

Mitigation

  1. Harden VPNs and RDP: Enforce MFA on all VPN and RDP access. Do not expose RDP to the internet. This aligns with Multi-factor Authentication (M1032).
  2. Disable Unused Tools: Use application control policies to block the execution of tools commonly abused by threat actors (like PsExec, AdFind) if they are not required for legitimate administrative purposes. This is an application of Disable or Remove Feature or Program (M1042).
  3. Immutable Backups: Follow the 3-2-1 backup rule, ensuring that at least one copy of critical data is stored offline or in an immutable format, making it inaccessible to ransomware actors.
