Getting python struct.error: unpack requires a string argument of length #1

Hello Steve, Would it possible for you to give me an example of an APK file leading to the crashes you reported ? Best regards. |
|
We used QuranAndroid which is on Google Play. Also, we have found a workaround for this error by unpacking and repacking the APK using zip/unzip on Ubuntu. However, it should probably still be fixed in androwarn. |

Hello @StephenQuirolgico, Could you test again and tell me if the bug stills exists ? I'm in that environment:

Thomas,
Thank you very much! I’ll check it out and provide feedback. Again, thanks
very much!

FYI I just tested with the current QuranAndroid application on the Play
Store (version 2.9.1-p1) and I haven't encountered that issue, in that
environment:

Thomas,
I installed the latest version of Androguard and Androwarn and but I'm
getting a path error when running Androwarn:
File "/data/appvetBin/androwarn/androwarn.py", line 30, in
from androguard.misc import AnalyzeAPK
ImportError: No module named androguard.misc
Also, what versions of Python are you using for Androguard and Androwarn?
The new version of Androguard recommends v3.6 but Androwarn still says to
use v2.7.
Thanks,
Steve

Thomas,
For some reason, I'm unable to run pip install androwarn from this machine, so
I did a git clone and ran pip install -r requirements.txt instead Now, I
am getting a different error message:
…-bash-4.2# python /data/androwarn-master/androwarn.py -i
/home/squirolgico/test-apps/GrouPing.apk -v 1 -d -L ERROR -n
Traceback (most recent call last):
File "/data/androwarn-master/androwarn.py", line 31, in <module>
from warn.search.search import grab_application_package_name
File "/data/androwarn-master/warn/search/search.py", line 25, in <module>
from warn.util.util import *
File "/data/androwarn-master/warn/util/util.py", line 25, in <module>
from HTMLParser import HTMLParser
ModuleNotFoundError: No module named 'HTMLParser'
I am using Python 3.6.6.
Also, there were a couple of print statements in androwarn.py that needed
parentheses (for Python 3.x).
Thanks,
Steve

The minimum androguard version is documented in the requirements.txt file
<https://github.com/maaaaz/androwarn/blob/master/requirements.txt>, to
date it's >= 3.2.1.
Could you try a simple pip install androwarn ?

Okay, |
|
Thanks, Thomas. Please let me know if Androwarn moves to Python >=3.6.
Also, are there plans to implement CVSS (Common Vulnerability Scoring
System) and/or NIAP to Androwarn? Androwarn is currently being used by the
US Govt as part of a suite of tools for testing Android apps. Having CVSS
and/or NIAP would help to maintain its position as a cost-effective
solution for helping to ensure the safety of Android apps used by federal
agencies.
Thanks,
Steve

Okay, androwarn is, for the moment, a Python 2-only program.

Hello @StephenQuirolgico, Androwarn now works with Python 3. Cheers. |

Thanks Thomas — I’ll check it out.

For some apps, we are getting a python struct error. I don't know if this is a problem with androwarn, python, or the APK file itself. Below is an example error message. How can we fix this?
Traceback (most recent call last):
File "/home/blive/androwarn/androwarn-master/androwarn.py", line 116, in
main(options, arguments)

a, d, x = AnalyzeAPK(APK_FILE)
File "/home/blive/androwarn/androwarn-master/androwarn/analysis/analysis.py", line 48, in AnalyzeAPK
a = APK(filename, raw)
File "/home/blive/androwarn/androwarn-master/androguard/core/bytecodes/apk.py", line 156, in init
self.zip = zipfile.ZipFile( StringIO.StringIO( self.raw ), mode=mode )

tp, ln = unpack('<HH', extra[:4])
