Re: [Vol-users] Sample error or real module? (and other questions)

Thanks Michael. I did try that, and received an error. That's why I thought I must be doing/forgetting something stupid. Now that I'm back at my analysis machine, here's the output: Traceback (most recent call last): File "<console>", line 1, in <module> NameError: name 'f9805ba44800' is not defined <volatility.plugins.addrspaces.amd64.AMD64PagedMemory object at 0xbef520c> Note that I'm using Volatilty through the VM provided for the most recent class in Reston, in case the version is in question. The profile for this sample is WIn7SP1x64.
