About

Fusion is the next step from the protostar setup, and covers more advanced styles of exploitation, and covers a variety of anti-exploitation mechanisms such as: + Address Space Layout Randomisation + Position Independent Executables + Non-executable Memory + Source Code Fortification (_DFORTIFY_SOURCE=) + Stack Smashing Protection (ProPolice / SSP)

In addition to the above, there are a variety of other challenges and things to explore, such as: + Cryptographic issues + Timing attacks + Variety of network protocols (such as Protocol Buffers and Sun RPC) + At the end of Fusion, the participant will have a through understanding of exploit prevention strategies, associated weaknesses, various cryptographic weaknesses, numerous heap implementations.

Getting started

Have a look at the levels available on the side bar, and pick which ones interest you the most. If in doubt, begin at the start. You can log into the virtual machine with the username of "fusion" (without quotes), and password "godmode" (again, without quotes).

To get root for debugging purposes, do "sudo -s" with the password of "godmode".

About

Nebula takes the participant through a variety of common (and less than common) weaknesses and vulnerabilities in Linux. It takes a look at + SUID files + Permissions + Race conditions + Shell meta-variables + $PATH weaknesses + Scripting language weaknesses + Binary compilation failures At the end of Nebula, the user will have a reasonably thorough understanding of local attacks against Linux systems, and a cursory look at some of the remote attacks that are possible.

Levels

Have a look at the levels available on the side bar, and log into the virtual machine as the username "levelXX" with a password of "levelXX" (without quotes), where XX is the level number.

Some levels can be done purely remotely.

Getting root

In case you need root access to change stuff (such as key mappings, etc), you can do the following:

Log in as the "nebula" user account with the password "nebula" (both without quotes), followed by "sudo -s" with the password "nebula". You'll then have root privileges in order to change whatever needs to be changed.

About

Protostar introduces the following in a friendly way:

• Network programming
• Byte order
• Handling sockets
• Stack overflows
• Format strings
• Heap overflows The above is introduced in a simple way, starting with simple memory corruption and modification, function redirection, and finally executing custom shellcode.

In order to make this as easy as possible to introduce Address Space Layout Randomisation and Non-Executable memory has been disabled.

Getting started

Once the virtual machine has booted, you are able to log in as the "user" account with the password "user" (without the quotes).

The levels to be exploited can be found in the /opt/protostar/bin directory.

For debugging the final levels, you can log in as root with password "godmode" (without the quotes)

Core files

README! The /proc/sys/kernel/core_pattern is set to /tmp/core.%s.%e.%p. This means that instead of the general ./core file you get, it will be in a different directory and different file name.
