Toll scam software that enables automated subscription to premium services has been warned against by Microsoft. One of the most common risks to Android smartphones is malware.


Malware used in toll fraud


Technical details on how toll fraud malware operates and how it may be blocked on Android are provided in a thorough report by Microsoft.


Wireless Application Protocol (WAP), which enables customers to subscribe to premium content, is how toll fraud operates.


The consumer must click a subscription button to complete the process, which requires a connection over the mobile network.


The spyware gathers information on the subscriber’s nation and cell network, and Android needs permission to do this.

Malware threats that enable toll fraud automatically carry out the aforementioned procedures by starting phoney subscriptions, watching OTPs, and turning off notifications that would alarm the victim.


Remaining discrete

If the mobile network of infected devices is not on the list, the malware controllers have put in place techniques to keep the spyware static. This keeps the bad behaviour a secret.

Another method is dynamic code loading, which only permits some code to load under specific circumstances. This makes detecting the spyware tougher.

Additional Perspectives

Disabling WiFi and forcing the device to utilise the operator’s network is another common malware method. With a standard protection permission level, this is possible on Android version 9 or any older version.

The’requestNetwork’ method for higher API levels is covered by the CHANGE NETWORK STATE permission and has an additional average protection level.

Security advice

Users are advised to make sure they download apps or other media from a trustworthy source in order to protect themselves against toll scam virus. Additionally, to lessen the chance of malware spreading like wildfire on cellphones, constantly pay attention to the permissions given during installation.
