Works only for apk size < 16MB about mara_framework HOT 10 CLOSED

The 16MB apk file size restriction for APK DeGuard was lifted and it now supports unlimited APK sizes.

That is correct. The tools uses apk-deguard for the deobfuscation hence the reason for that limit. You could have a look at mobile security wiki for a list of other deobfuscation tools.

Which one would you recommend?

from mara_framework.

I suggest you try all of them and see which one works for you. On my end, i had mixed results, so i opted for apk-degard and with large APKs i put more effort on dynamic analysis.

The deobfuscation problem can be easily solved if we can obtain the mapping file somehow (here). I don't know how to do proceed on this. Could you suggest me any pointers?

from mara_framework.

That is quite true. However in most cases you won't get the mapping file together with the APK you want to analyze. As for the deobfuscator in MARA, that mapping file is generated by apk-deguard.

I reached out to Prof. Dr. Martin Vechev on increasing the APK size limit, and he said that a new version is soon to be released. So we just have to wait till then.

You could try this one. I haven't tried it though.

Thanks for the link.

Unfortunately, for us the java deobfuscator doesn't support proguard. Thanks for helping out though. I am trying to create a web application around MARA using flask (python). Have been somewhat successful; stuck at this juncture.

Did he mention anything regarding whether he would open-source the project or not?

I guess we'll have to wait till then

from mara_framework.

Nice! That's pretty neat. Can't wait to see the MARA web app. You can try reach him on his email [email protected] for any inquiries you may have.

With all due respect @xtiankisutsa , I think the issue is still open.
You may add this to a milestone for an upcoming release.

Thanks @xandfury, I have re-opened this issue, and will update the deobfuscation module as soon as Martin makes the apk-deguard API available.
