Только вместо Python запускать нужно Iptables для блокировки ненужных Ip

on beacon_initial {
    println("Initial Beacon Checkin: " . $1 . " PID: " . beacon_info($1, "pid"));

    $externalIP = replace(beacon_info($1, "external"), " ", "_");
    $computerName = replace(beacon_info($1, "computer"), " ", "_");
    $userName = replace(beacon_info($1, "user"), " ", "_");

    if ($computerName == "" ||
        str_contains($computerName, "john") ||
        str_contains($computerName, "borisov")) {

        local('$cmd');
        $cmd = 'iptables -A INPUT -s '. $externalIP . '/24 -j DROP';
        exec($cmd);

        println("Blocked IP range: " . $externalIP . " for computer: " . $computerName);
        println($cmd);

    } else {
        println("No matching computer name found. Skipping IP block.");
    }
}
