# API Reference: Detecting Mobile Malware Behavior
|
|
|
|
## Android Dangerous Permissions
|
|
|
|
| Permission | Risk | Abuse Scenario |
|
|
|------------|------|---------------|
|
|
| SEND_SMS | HIGH | Premium rate SMS fraud |
|
|
| READ_SMS | HIGH | OTP/2FA theft |
|
|
| BIND_ACCESSIBILITY_SERVICE | CRITICAL | Screen scraping, keylogging |
|
|
| BIND_DEVICE_ADMIN | CRITICAL | Device lockout, ransomware |
|
|
| INSTALL_PACKAGES | CRITICAL | Dropper functionality |
|
|
| SYSTEM_ALERT_WINDOW | HIGH | Overlay phishing attacks |
|
|
|
|
## Android Analysis Tools
|
|
|
|
```bash
|
|
# Extract permissions from APK
|
|
aapt dump permissions app.apk
|
|
|
|
# Decompile APK
|
|
apktool d app.apk -o output_dir/
|
|
|
|
# Decompile to Java source
|
|
jadx app.apk -d java_output/
|
|
|
|
# Run MobSF scan
|
|
docker run -p 8000:8000 opensecurity/mobile-security-framework-mobsf
|
|
```
|
|
|
|
## Suspicious API Patterns
|
|
|
|
```python
|
|
# Dynamic code loading
|
|
r"DexClassLoader|PathClassLoader"
|
|
# Shell execution
|
|
r"Runtime\.exec|ProcessBuilder"
|
|
# Device fingerprinting
|
|
r"TelephonyManager\.getDeviceId"
|
|
```
|
|
|
|
## MobSF REST API
|
|
|
|
```python
|
|
import requests
|
|
# Upload APK
|
|
resp = requests.post("http://localhost:8000/api/v1/upload",
|
|
files={"file": open("app.apk", "rb")},
|
|
headers={"Authorization": API_KEY})
|
|
|
|
# Get scan results
|
|
resp = requests.post("http://localhost:8000/api/v1/scan",
|
|
data={"hash": file_hash},
|
|
headers={"Authorization": API_KEY})
|
|
```
|
|
|
|
## Android Broadcast Receivers (Persistence)
|
|
|
|
| Action | Malware Use |
|
|
|--------|-------------|
|
|
| BOOT_COMPLETED | Auto-start on reboot |
|
|
| SMS_RECEIVED | SMS interception |
|
|
| PHONE_STATE | Call monitoring |
|
|
| CONNECTIVITY_CHANGE | Network-triggered C2 |
|
|
|
|
## CLI Usage
|
|
|
|
```bash
|
|
python agent.py --apk suspicious.apk
|
|
python agent.py --source-dir jadx_output/
|
|
python agent.py --apk app.apk --source-dir decompiled/
|
|
```
