Analysis time between the old version and 2.5.1 #46

Open yedyed opened 6 years ago

Hi, Currently, I'm trying to switch using the previous versions of FlowDroid to the current version (2.5.1). As I can see, the current version never finish its job, it exceeded more than 12 hours, but the previous one has used only 28-29 seconds for the same APK file.

Here is the command for 2.5.1 which I use: java -Xmx60g -jar soot-infoflow-cmd-jar-with-dependencies.jar -a app_test1.apk -p /FlowDroid/android-platforms/platforms -s SourcesAndSinks.txt -o flowdroid/test.xml --nostatic --aliasflowins --aplength 1 --noexceptions

The previous version: java -Xmx60g -cp soot-trunk.jar:soot-infoflow.jar:soot-infoflow-android.jar:slf4j-api-1.7.5.jar:slf4j-simple-1.7.5.jar:axml-2.0.jar soot.jimple.infoflow.android.TestApps.Test ../source/app_test1.apk /FlowDroid/android-platforms/platforms ... Maximum memory consumption: 1535.117312 MB Analysis has run for 28.42890296 seconds

Please give me advice to optimise this.

Cheers

Can you please provide the APK file with which you encounter the problem?

Hi Steven,

This is the APK file which I use it to test. https://github.com/yedyed/samples/raw/master/ransom1.apk (f836f5c6267f13bf9f6109a6b8d79175) PS. it is ransomware http://contagiominidump.blogspot.com/2015/06/androidtrojanslockerdz-fake-videoplayer.html.

Many thanks
