This new version has many new features and options.

First there is the remainder (*) when using option -f to specify a parsing format.

For example, -f “<i25s” directs format-bytes to interpret the provided data as a little-endian integer followed by a 25-byte long string:

With the remainder (-f “<i25s*”), format-bytes will provide info for the remaining bytes (if any) after parsing (e.g. after the 25-byte long string):

Options -c and -s changed ito -C and -S, so that option -s can be used to select items (to be consistent across my tools).

Option -s can be used to select an item, like a string, to be dumped (options -a, -x and -d). If no dump option is provided, an hex-ascii dump (-a) is the default.

And option –jsoninput can be used to process JSON output produced by oledump.py or zipdump.py, for example.

This new version of oledump.py adds option –vbadecompressskipattributes to decompress VBA code while skipping the initial attribute definitions (those that are hidden in the MS Office VBA Editor).

Here is an example of output with option -v you are familiar with:

When replacing option -v with option –vbadecompressskipattributes, the initial attributes are no longer displayed:

These attributes are actually hidden in the MS Office VBA Editor:

I added this option because lately, I’ve analyzed several samples where I had to extract all strings for further decoding, and the strings in the attribute definitions were interfering with the decoding. With this new options, I can prevent these strings from appearing in the output.

plugin_msg.py was updated to version 0.0.3 to include plugin option -k, to display only known MSG streams.

This new version of python-per-line.py adds new options: –grep, –grepoptions, –begingrep, –begingrepoptions, –endgrep and –endgrepoptions

With –grep and –grepoptions, you can select the lines to be processed by python-per-line.py.

If you want to skip lines at the beginning of the file, use option –begingrep to grep for the first line where processing should start.

And if you want to skip lines at the end of the file, use option –endgrep to grep for the last line to be processes.

This new version of numbers-to-string.py adds new options: –grep, –grepoptions, –begin and –end.

With –grep and –grepoptions, you can select the lines to be processed by numbers-to-string.py.

And if you don’t want the tool to take a whole line into account when processing numbers, but only part of the line, you can use option –begin to specify where in the line processing should start.

Likewise, with –end you can specify where processing should end.

This new version of re-search adds 3 regular expressions to the library: str-e matches quoted strings like str but including the empty string too. str-u matches strings like str, but strips the double quotes. str-eu matches like str-e and also strips double quotes.

This new version of base64dump adds option -I (ignorehex). Like -i, -I can be used to specify characters to be ignore by base64dump. Option -I takes the characters to be ignored as hexadecimal values, like this:

base64dump.py -I 2209

This will ignore the double-quote character (0x22) and the TAB character (0x09).

2 new operations were added to this version: sample and join.
