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.
