abo1.exe advanced_buffer_overflow challenge is packed, I've tried to unpack it, but I am still beginner in unpacking.It seems it is packed manually. I've also tried OllyDump and ImortREC.
Can any body give me a hand on unpacking it? Here is the file : http://www.binary-auditing.com/binary-auditing-training-package.zip
