Do you trust that current security measures adequately protect organizations from modern ransomware threats?
Security researchers have identified the operational playbook of the Play ransomware group, also known as PlayCrypt. The group executes double-extortion attacks by exfiltrating sensitive data before encrypting local systems.
Why it matters
Understanding these specific attack vectors is critical for organizations to secure their perimeters, as the group demonstrates a high level of sophistication in bypassing endpoint security tools.
The group gains initial access via SonicWall VPN vulnerabilities before moving laterally using Mimikatz—a credential harvesting tool—and PsExec, a command-line utility for remote process execution.
The players
Play ransomware group
An organized threat actor also known as PlayCrypt that executes double-extortion ransomware attacks.
SonicWall
A developer of network security appliances and VPN hardware used as an entry point in these attacks.
SentinelOne
A cybersecurity firm that produces endpoint protection software later weaponized by the attackers.
The details
PlayCrypt employs a systematic approach to disabling security software by leveraging the victim's own SentinelOne uninstallation utility. Attackers stage tools through the SYSVOL directory and SystemBC malware, while clearing event logs and using WinSCP—a secure file transfer client—to manage stolen data. These actions demonstrate a focus on evading detection while maintaining persistence within target environments.
Timeline
October 3, 2026: Investigative research detailing Play ransomware activities was published.
The Tech Race
This disclosure highlights a shift in ransomware operations toward utilizing legitimate administrative software to bypass modern endpoint protection. It follows a pattern set by the 2021 Kaseya VSA supply chain attack, where attackers increasingly weaponize existing infrastructure to maintain long-term persistence.
Organizations relying on SonicWall VPNs should immediately verify that all firmware is patched and that administrative access is restricted. IT teams should monitor for the presence of unauthorized WinSCP activity and unusual usage of built-in uninstallation utilities.
The takeaway
Security teams should prioritize monitoring for the specific use of legitimate uninstallation utilities as a marker of an active breach. Watch for future updates from incident response firms regarding the expansion of PlayCrypt's target list across new infrastructure types.
