What is an information-stealing ad library?
When it comes to free apps, there still may be a price, although it doesn’t always cost the user. There are other ways applications can earn revenue, such as running advertisements within the app itself. Ad libraries are a legitimate part of an application, however, they are software and can become compromised by cybercriminals in a myriad of different ways.
What does Xavier do?
This particular variant of the malicious ad library is what is known as a Trojan horse. This type of malware can collect sensitive user information such as email addresses, Device ID, device model, operating system version, country, device manufacturer, SIM card operator, screen resolution, and installed apps, all without the users knowledge.
