How Vapor Malware Operates
Vapor malware disguises itself as legitimate apps, often promising utility and useful features. While some of these apps initially function as advertised, adware capabilities are introduced later through updates. The malware is heavily obfuscated, detecting when it is launched in a virtual or debugging environment to prevent security analysis.
One of its most alarming features is its ability to bypass Android 13 security restrictions without requesting extensive permissions. Vapor malware utilizes Android ContentProvider to gain a foothold in the system automatically upon installation. This enables it to hide its icon, preventing users from easily locating and uninstalling it. Some variants even attempt to disappear from the device settings.
Additionally, Vapor collects sensitive device information, such as:
- Device brand and model
- Unique identifiers
- Geolocation data
- Language settings
The Adware Component
The primary objective of Vapor is monetization through aggressive advertising. It delivers interstitial ads (full-screen advertisements that overlay app interfaces). Many of these ads contain malicious links leading to phishing pages, scam promotions, and malware-laden websites.
Cybercriminals use Vapor to conduct phishing scams, tricking users into entering login credentials, personal information, and credit card details. This stolen data is then exploited for fraudulent transactions and identity theft.
