Are there any tools for simulating attacks on Bitcoin network?

I'm working on my thesis about Bitcoin security, and I'm wondering if there is any software available for simulating various attacks on Bitcoin network / testnet?

Doesn't gavinandresen have a protocol fuzzer?

... but it is pretty narrowly targeted at stress-testing the transaction validity code.

Last year at the NYC conference I mentioned that I would really like to see somebody who knows a lot more about network simulation than I do develop tools to help test proposed protocol changes, simulate Sybil or DoS attacks, etc.

I'd still really like to see that...

You got it!

I created this...

Was just to simulate how Address messages propagated.

Also simulates how transactions/blocks get sent.

Could easily adapt to see what happens if someone tries to dos the network.

afiak Yifu from BitSyncom is to plan to test-execute a Finny Attack with Sybil elements on the prod-network after they get back from GDC, and documenting how hard is actually to pull off, and how it is generally a no-issue to accept 0 confirmation tx and talk about how to minimize risk.
