search term

Hi :), In the previous post, I discussed automation of decompiling apks. Now, let’s have a look on how to check the availability of some text or term in the decompiled files.

So let’s continue our python script

decompileApk.py

#---------------------------filter for any term-------------------------------

#Create a new folder to include output files
if not os.path.exists(walk_dir + "_Decompiled/Outputs"):
 os.makedirs(walk_dir + "_Decompiled/Outputs")

primary_path = os.path.dirname(os.path.abspath("decompileApk.py"))
root_output = ''

# Create output file for each apk file
for dirs in os.walk(walk_dir+ "_Decompiled").next()[1]:
 root_output = os.path.join(walk_dir+ "_Decompiled/Outputs", dirs+'_output_paypal.txt')
 with open(root_output, 'a') as f:
 f.close

for root, subdirs, files in os.walk(walk_dir+ "_Decompiled"):

# exclude the files with .py
if 'Outputs' in subdirs:
 subdirs.remove('Outputs') 
 files = [ fi for fi in files if not fi.endswith(".py") ]

parent_directory = os.path.split(os.path.abspath(os.path.join(root, os.pardir)))[1]
if os.path.exists('./Outputs/'+parent_directory+'_output_paypal.txt'):
 root_output = os.path.join(walk_dir+ "_Decompiled/Outputs", parent_directory+'_output_paypal.txt') 
 
 with open(root_output, 'a') as f:
 for filename in files: 
    file_path = os.path.join(root, filename) 
 (out,err) = subprocess.Popen(['grep', '-rinIe', 'okhttp',file_path],stdout=f,stderr=f).communicate()
    print('--\nfile_path = ' + file_path)
    print out 
 f.close;
