An Obfuscation-Neglect Android Malware Scoring System

# Quark Script - Dig Vulnerabilities in the BlackBox

### Innovative & Interactive

• The goal of Quark Script aims to provide an innovative way for mobile security researchers to analyze or pentest the targets.
• Based on Quark, we integrate decent tools as Quark Script APIs and make them exchange valuable intelligence to each other. This enables security researchers to interact with staged results and perform creative analysis with Quark Script.

### Dynamic & Static Analysis

• In Quark script, we integrate not only static analysis tools (e.g. Quark itself) but also dynamic analysis tools (e.g. objection).

### Re-Usable & Sharable

• Once the user creates a Quark script for specific analysis scenario. The script can be used in another targets. Also, the script can be shared to other security researchers. This enables the exchange of knowledges.

### More APIs to come

• Quark Script is now in a beta version. We'll keep releasing practical APIs and analysis scenarios.
• See API document here.

# Quick Start

In this section, we will show how to detect CWE-798 with Quark Script.

### Step 1: Environments Requirements

• Quark requires Python 3.8 or above.

### Step 2: Install Quark Engine

• Install Quark Engine by running:
$pip3 install -U quark-engine  ### Step 3: Prepare Quark Script, Detection Rule and the Sample File 1. Get the CWE-798 Quark Script and the detection rule here. 2. Get the sampe file (ovaa.apk) here. 3. Put the script, detection rule, and sample file in the same directory. 4. Edit accordingly to the file names: SAMPLE_PATH = "ovaa.apk" RULE_PATH = "findSecretKeySpec.json" # Now you are ready to run the script!  ### Step 4: Run the script $ python3 CWE-798.py

# You should now see the detection result in the terminal.
