MADLIRA

Malware detection using learning and information retrieval for Android

Overview

MADLIRA is a tool for Android malware detection. It consists in two components: TFIDF component and SVM learning component. In gerneral, it takes an input a set of malwares and benwares and then extracts the malicious behaviors (TFIDF component) or computes training model (SVM classifier). Then, it uses this knowledge to detect malicious behaviors in the Android application.

Insalling

Download file MADLIRA.7z and decompress it.

Installed Data:

MADLIRA.jar is the main application.
noAPI.txt declares the prefix of APIs.
family.txt lists malwares by family.
Folder TrainData contains the training configuration and training model.
Folder Samples contains sample data.
Folder TempData contains data for kernel computation.

Functionality

This tool have two main components: TFIDF component and SVM component.

TFIDF component

Command: java -jar MADLIRA TFIDF

For this component, there are two functions: the training function (Malicious behavior extraction) and the test function (Malicious behavior detection)

Malicious behavior extraction

Collect benign applications and malicious applications and oput them in folders named benginAPKFolder and maliciousApkFolder, respectively.
Prepare training data and pack them in two files named benignPack and maliciousPack by using the command:

MADLIRA TFIDF packAPK -PB benignApkFolder -B benignPack -PM maliciousApkFolder -M maliciousPack

Extracting malicious behaviors from two packed files (benignPack and maliciousPack) by using the command:

java -jar MADLIRA TFIDF train -B benignPack -M maliciousPack

Malicious behavior detection

Collect new applications and put them in a folder named checkApk.
Detect malicious behaviors of applications in the folder checkApk by using the command:

java -jar MADLIRA TFIDF check -S checkApk

Command:

java -jar MADLIRA TFIDF train <Options>
        Compute the malicious specifications for given training data.
                -B <filename>: the archive file contains all graphs of training benwares.
                -M <filename>: the archive file contains all categories of training malwares.

java -jar MADLIRA TFIDF check <Options>
        Check malicious behaviors in the given applications in a folder.
                -S <folder>: the folder contains all applications (apk files).

java -jar MADLIRA TFIDF test <Options>
        Test the classifier for a given test data.
                -S <folder>: the folder contains all graphs for testing.

java -jar MADLIRA TFIDF clear
        Clean all training data.

java -jar MADLIRA TFIDF install
        Clean old training data and install a new data for training.
                -B <filename>: the archive file contains all graphs of training benwares.
                -M <filename>: the archive file contains all categories of training malwares.

Examples:

Training new data:

First collect training applications (APK files) and store them in folders named MalApkFolder and BenApkFolder.
Pack training applications into archive files named MalPack and BenPack by using this command:

java -jar MADLIRA TFIDF packAPK -PB BenApkFolder -B BenPack -PM MalApkFolder -M MalPack

Clean old training data:

java -jar MADLIRA TFIDF clear

Compute the malicious graphs from the training packs (BenPack and MalPack)

java -jar MADLIRA TFIDF train -B BenPack -M MalPack

Checking new applications:

put these applications in a folder named checkApk and use this command:

java -jar MADLIRA TFIDF check -S checkApk

Output: output

SVM component

Command: java -jar MADLIRA SVM

For this component, there are two functions: the training function and the test function.

Training phase

Collect benign applications in a folder named benignApkFolder and malicious applications in a folder named maliciousApkFolder.
Prepare training data by using the commands:

java -jar MADLIRA SVM packAPK -PB benignApkFolder -B benignPack -PM maliciousApkFolder -M maliciousPack

Compute the training model by this command:

java -jar MADLIRA SVM train -B benignPack -M maliciousPack

Malicious behavior detection

Collect new applications and put them in a folder named checkApk
Detect malicious behaviors of applications in the folder checkApk by using the command:

java -jar MADLIRA SVM check -S checkApk

Command:

java -jar MADLIRA SVM train <Options>
        Compute the classifier for given training data.
                -T <T>: max length of the common walks (default value = 3).
                -l <lambda>: lambda value to control the importance of length of walks (default value = 0.4).
                -B <filename>: the archive file contains all graphs of training benwares.
                -M <filename>: the archive file contains all graphs of training malwares.

java -jar MADLIRA SVM check <Options>
        Check malicious behaviors in the applications in a folder.
                -S <foldername>: the folder contains all apk files.

java -jar MADLIRA SVM test <Options>
        Test the classifier for given graph data.
                -S <foldername>: the folder contains all graphs of test data.
                -n <n>: the number of test samples.

java -jar MADLIRA SVM clear
        Clean all training data.
