Microsoft warns about Android malware that could secretly steal your money

• Microsoft has issued a warning to Android users about toll fraud malware that is constantly evolving.
• This type of malware subscribes unsuspecting users to premium services without their knowledge.
• Hefty subscription fees will then be charged on your monthly phone bill with no consent.

Microsoft has warned users of older versions of the operating system that there is a threat to their wallet.

About toll fraud is a type of billing fraud that is designed to sign you up for unwanted premium services without your consent. It is one of the most dangerous types of software because it is constantly changing.

The Wireless Application Protocol (WAP) is a billing mechanism that is abused by toll fraud software. Users can be charged for paid content through their phone bill.

The toll fraud software automatically enrolls you in premium services. The attack begins when you are disconnected from a wi-fi network. When you're connected to a mobile network, the malicious software opens a subscription page and subscribes on your behalf. After reading an one-time password, it will fill out the required fields to complete the process. The attackers are able to hide this activity.

The hefty charges on your phone bill are one of the risks posed by this software. The toll fraud is designed to be difficult to detect.

According to Microsoft, toll fraud is hidden behind legitimate apps that are designed to request permission beyond what is required. An example is a camera app that asks for permission to send text messages.

The researchers noted that the software targets older versions of the phone's operating system. If you're running a newer version of the OS, you're safe, but it's worth using some of the best apps for protection. Users are reminded not to install apps from unreliable sources.
