numbers-to-string.py is a tool to help with deobfuscation: it transforms numbers found in its input into strings.
This new version adds option -b to produce binary output.

This new version of cut-bytes.py, a tool to select a byte sequence from its input, has bug fixes (including Python 3 fixes) and 2 new options: -p –prefix and -s –suffix.
With these options, arbitrary data can be prefixed or appended to the input.

This new version of pecheck.py, a tool to analyze PE files, comes with a small update to option -l.
The overview of embedded PE files produced with option -l P now reports the hash of the embedded PE file without overlay:
By default, this is an MD5 hash, but can be changed to your liking using environment variable DSS_DEFAULT_HASH_ALGORITHMS, like this:
I will introduce this environment variable to my other tools with new releases.

My new tool simple_tcp_stats.py is a Python program that reads pcap files and produces simple statistics for each TCP connection.
For the moment, it calculates the entropy of the data (without packet reassembling) of each TCP connection (both directions) and reports this with a CSV file:

This is an update of my PDF tools.
There are a couple of bug fixes for pdf-parser and pdfid.
And 2 new features in pdf-parser, inspired by a private training on maldoc analysis I gave last week. I often get good ideas from my students, and sometimes, even I get a good idea in class đŸ™‚ .
Option -o can now be used to select multiple objects: separate the indices by a comma.
There’s a new environment variable, PDFPARSER_OPTIONS, that can be used to provide extra options you want to include with each execution of pdf-parser.py. This is useful for option -O, an option to parse stream objects.
It’s actually best to always parse stream objects, i.e. always use option -O. But I decided not to make this an option that is on by default, so that the behavior of pdf-parser would remain unchanged. I consider this important for the many people that rely on a predictable behavior of pdf-parser, like teachers and students of infosec trainings where my tools are used/mentioned.
However, always including option -O is tedious and error prone. So now you can have best of both worlds, by defining an environment variable with name PDFPARSER_OPTIONS and value -O.
And finally, I started to add a man page (option -m), like I do with many of my other tools. This is a work in progress: for the moment, it points to my free PDF analysis e-book that explains the use of pdfid and pdf-parser.

hex-to-bin.py is a program to convert hexadecimal dumps (text) to binary data.
This new version of hex-to-bin.py can handle different hexdump formats, like registry dumps (text files). Use option -x to handle these hexdumps.
And option -t was added if the input is a text file that is non-ASCII, like UTF16. Option -t can be used to convert the text file.
And it supports Python3, but that code is a kludge. Something I’ll have to do better later.

This new version of msoffcrypto-crack.py, a simple tool to crack passwords of MS Office documents, adds rules via option -r.
In this release, there is only one rule to modify candidate passwords: case toggle.
If you use option -r, all passwords in the provide list will be tested, together with their case toggle variant: Secret -> sECRET.
