Python reading a PE file and changing resource section
I am trying to open a Windows PE file and alter some strings in the resource section.
f = open('c:testfile.exe', 'rb')
file = f.read()
if b'A'*10 in file:
s = file.replace(b'A'*10, newstring)
In the resource section I have a string that is just:
AAAAAAAAAA
And I want to replace that with something else. When I read the file I get:
x00Ax00Ax00Ax00Ax00Ax00Ax00Ax00Ax00Ax00A
I have tried opening with UTF-16 and decoding as UTF-16 but then I run into a error:
UnicodeDecodeError: 'utf-16-le' codec can't decode bytes in position 1604-1605: illegal encoding
Everyone I seen who had the same issue fixed by decoding to UTF-16. I am not sure why this doesn't work for me.

What codes are those, in that position 1604-1605? Windows does not use UTF-16, it has a multibyte wide encoding of its own. Presumably – just like with a UTF-8 file that contains nothing higher than a tilde – those others for whom it worked just got lucky.

If resource inside binary file is encoded to utf-16, you shouldn't change encoding.
try this
f = open('c:\test\file.exe', 'rb')
file = f.read()
unicode_str = u'AAAAAAAAAA'
encoded_str = unicode_str.encode('UTF-16')
if encoded_str in file:
s = file.replace(encoded_str, new_utf_string.encode('UTF-16'))
inside binary file everything is encoded, keep in mind
