How NativeWorm Works
Contacts Exfiltration
NativeWorm first gains access to the Contacts application and extracts phone numbers and names. The stolen data allows attackers to send malware-laced phishing messages to a victim’s contacts, propagating NativeWorm or other malicious payloads.
SMS Interception
The malware is capable of reading SMS messages, which poses several threats:
- 2FA Code Theft: Many online services send one-time passwords (OTPs) for authentication via SMS. NativeWorm steals these messages, allowing attackers to bypass security measures.
- Private Conversations Exposure: Attackers may blackmail victims or use personal data for social engineering scams.
- Financial Fraud: If a message contains banking details or passwords, cybercriminals could use this information for unauthorized transactions.
Device Information Theft
NativeWorm collects device-specific data, including:
- Device model
- OS version
- Installed applications
- Unique device identifiers
This information can be used to track the user, personalize further attacks, or sell data on the dark web.
Symptoms of NativeWorm Infection
If your Android device exhibits the following symptoms, it may be infected with NativeWorm:
✅ Sluggish Performance – The device becomes slow due to background data exfiltration.
✅ Battery Drain – The malware continuously runs in the background, consuming battery life.
✅ Increased Data Usage – NativeWorm transmits stolen data over the internet, leading to unexpected spikes in data usage.
✅ Unauthorized Settings Modifications – Security settings may be altered, disabling security features.
✅ Unwanted Applications – New, suspicious apps may appear on your device.
✅ Intrusive Advertisements – Pop-ups and redirects may appear even when not using the browser.
✅ Strange SMS Activity – Your device may send spam messages to contacts without your knowledge.
How Does NativeWorm Spread?
Malicious Advertisements
Cybercriminals embed malware within fraudulent ads on suspicious websites. Clicking on these ads can initiate an automatic malware download.
Fake/Deceptive Apps
Users who download apps from third-party stores or unknown sources are at risk. Malicious apps may disguise themselves as legitimate tools, tricking users into granting permissions.
Phishing Messages
Attackers send fraudulent SMS or email messages containing infected links. When victims click these links, the malware gets installed.
Scam Websites
Visiting malicious websites that prompt users to download a required “update” or “security patch” can trigger an infection.
