<code class="language-bash">
./ -n document.pdf
./ -s objstm document.pdf

# decode stream objects ('-f' = filter)
./ -s objstm -f document.pdf

# force '' to parse the output of above (even though it's
# missing a proper PDF header)
./ -s objstm -f document.pdf | ./ -n -f

# which is (I think?) is roughly the same as
./ -a -O document.pdf

Decompress FlateDecode Objects in PDF
Tips on how to get working in Python 3 here:

<code class="language-python">import re
import zlib

pdf = open("some_doc.pdf", "rb").read()
stream = re.compile(r'.*?FlateDecode.*?stream(.*?)endstream', re.S)

for s in stream.findall(pdf):
s = s.strip('\r\n')

PyREBox is a Python scriptable Reverse Engineering sandbox. It is based on QEMU, and its goal is to aid reverse engineering by providing dynamic analysis and debugging capabilities from a different perspective. PyREBox allows to inspect a running QEMU VM, modify its memory or registers, and to instrument its execution, by creating simple scripts in python to automate any kind of analysis. QEMU (when working as a whole-system-emulator) emulates a complete system (CPU, memory, devices...). By using VMI techniques, it does not require to perform any modification into the guest operating system, as it transparently retrieves information from its memory at run-time.

ReversingHero - Learn Reverse Engineering
What is Reverse Engineering?

Reverse Engineering is the process of taking something and trying to figure out how it works from the inside.

Reverse Engineering a computer program is done by reading the low level machine code it is made of, and understanding how it works internally.
Why learn Reverse Engineering?

You are curious about how things really work.
Reverse Engineering is a fundamental technological skill. If you can understand how computer programs work, you can do anything.
Reverse Engineering is an important skill for any security researcher or pentester.
Become a better developer by understanding how the programs you write work from the inside.
