!exploitable is a crash analyzer plug-in for windows debugger (windbg) that does post-mortem analysis of a crash and assists its security risk, very cool! The project is licensed under Microsoft Public License (Ms-PL) and you can download it at codeplex. The analyzer rates the crash one of the following ratings: Exploitable, Probably Exploitable, Probably Not Exploitable, or Unknown. Here are the usage instructions as listed on the project’s website:

!exploitable
Gives an analysis, including a proposed bug title

!exploitable -v
Gives a verbose analysis

!exploitable -m
Gives the same output as -v, but formatted for easy machine parsing

!exploitable -jit:address
Use the JIT Exception Record to determine the exception

!ror [-n <Rotation Count> [-c] <Value>
Get the API name for hash value <Value> using rotation count <Rotation Count>. Use -c to do a reverse lookup from an API name to a hash value. Run !ror without options for examples.

!xoru -b <addr> <length> <key>
Do the Xor transformation on the buffer from address <addr> to address <addr> + <length> using the key <key> and disassemble the buffer. Use -b to leave the transformed buffer in memory. Run !xoru without options for examples. You can do other types of transformation using xora, xorui, xorua, suba, subu, adda, addu, rola, or rolu.
