Analyzing Android Malware with Apktool

Name: analyzing-android-malware-with-apktool
Author: mukul975

Overview

Android malware distributed as APK files can be statically analyzed to extract permissions, activities, services, broadcast receivers, and suspicious API calls without executing the sample. This skill uses androguard for programmatic APK analysis, identifying dangerous permission combinations, obfuscated code patterns, dynamic code loading, reflection-based API calls, and network communication indicators.

When to Use

When investigating security incidents that require analyzing android malware with apktool
When building detection rules or threat hunting queries for this domain
When SOC analysts need structured procedures for this analysis type
When validating security monitoring coverage for related attack techniques

Prerequisites

Python 3.9+ with androguard
apktool (for resource decompilation)
jadx (for Java source recovery, optional)
Isolated analysis environment (VM or sandbox)
Sample APK files for analysis

Steps

Parse APK with androguard to extract manifest metadata
Enumerate requested permissions and flag dangerous combinations
List activities, services, receivers, and providers from manifest
Scan for suspicious API calls (reflection, crypto, SMS, telephony)
Detect dynamic code loading patterns (DexClassLoader, Runtime.exec)
Extract hardcoded URLs, IPs, and C2 indicators from strings
Generate risk assessment report with MITRE ATT&CK mobile mappings

Expected Output

JSON report with permission analysis, component listing, suspicious API calls, network indicators, and risk score
Extracted strings and potential IOCs from the APK

Use it

Copy one of these into your project. Installing also returns the manifest and these snippets.
