Play is a ransomware group that has been active since at least 2022 deploying Playcrypt ransomware against the business, government, critical infrastructure, healthcare, and media sectors in North America, South America, and Europe. Play actors employ a double-extortion model, encrypting systems after exfiltrating data, and are presumed by security researchers to operate as a closed group.[1][2]

Reach is how much of ATT&CK this group touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 176 ATT&CK groups only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.
