Update: search-for-compression.py Version 0.0.4
This tool is still beta.
VBA compression is now supported, besides zlib compression. Option -t (–type) was added so that one can choose the compression type to search for. Possible values are zlib (default) or vba.
And shortcut #p# was added to the yara option, to predefine these rules:
rule attribute_vb_name {
strings:
$a = "Attribute VB_Name = "
condition:
$a
}
rule dir {
strings:
$a = { 01 00 04 }
condition:
$a at 0
}
I’ll explain in another blog post how these features can be used to analyze MS Access databases with VBA project.

Update: myjson-transform.py Version 0.0.2
This update brings options -f and -c.
Option -f is used to define a Python function (function name or lambda) that will be applied to the content of each item in the MyJSON data.
Option -c is a shortcut for calling the CutData function via option -f. The lambda that is generated is: lambda data: CutData(data, ‘CUTEXPRESSION’)[0]
CUTEXPRESSION is the cut-expression provides as value for option -c.
