[Play](https://attack.mitre.org/groups/G1040) is a ransomware group that has been active since at least 2022 deploying [Playcrypt](https://attack.mitre.org/software/S1162) ransomware against the business, government, critical infrastructure, healthcare, and media sectors in North America, South America, and Europe. [Play](https://attack.mitre.org/groups/G1040) actors employ a double-extortion model, encrypting systems after exfiltrating data, and are presumed by security researchers to operate as a closed group.(Citation: CISA Play Ransomware Advisory December 2023)(Citation: Trend Micro Ransomware Spotlight Play July 2023)
