Today we are joined by Jean-Pierre Mouton, Senior Threat Intelligence Consultant at GuidePoint Security, discussing their work on "How Play Achieves Encryption." Play ransomware, also known as PlayCrypt, continues to target organizations across multiple sectors using a consistent double-extortion playbook that combines data theft with widespread encryption.
Summary
A recent investigation details how the group gained access through a SonicWall VPN, moved laterally using tools such as Mimikatz and PsExec, exfiltrated sensitive data, and used the victim’s own SentinelOne uninstallation utility to disable endpoint protection. The findings highlight several behavioral indicators defenders can monitor, including tool staging through SYSVOL and SystemBC for command and control, event log clearing, and suspicious WinSCP activity.
This is a brief wire summary, the full story (linked below) has the complete details.
KazaSec's take
Incidents like this rarely start with the headline event itself, they usually trace back to an exposed remote-access endpoint, an unpatched perimeter system, or a credential phished weeks earlier. The organizations that recover fastest are the ones that tested their defenses and their incident response plan before they needed them.
