At DEF CON Singapore 2026 Demo Labs I have presented RedTeamSimmer, an open-source way to run Atomic Red Team from the browser across many Windows machines at once.
I walked people through deploying agents, picking techniques from the ATT&CK catalog and running full emulation plans for groups like APT28, FIN7 and Lazarus. On the detection side, every technique is checked against Sigma, Splunk and Elastic rules, so a missing alert shows up the moment the technique runs.
