# Java 1.6.0u27 mass-pwner
# - run metasploit (./msfconsole -r ../BeEF.rc)
# - get browser plugins
# - get OS type and browser type/version
# - in order to achieve persistence:
#   - if the hooked browser is IE launch the iFrame above,
#   - otherwise MitB
# - launch get_system_info if java version is not exposed by plugins
# - retrieve exact version of the JDK
# - if JDK is vulnerable -> launch Rhino RCE exploit (reverse Java meterpreter)
