It should be noted that Google removed those tools from the Play Store after the reports, though these may still be active on many devices. That is why it is important to pay attention to the recommended security tips in case you have any of these programs active on your cell phone.
The following are the discovered applications, which were “disguised” as useful tools to infect devices to steal data and money. The first on the list is the one with the highest circulation, with more than 50,000 downloads.

A group of apps “loaded” with Joker malware
After the review of the Phone Arena site, the aforementioned malicious applications contain prankster malware, an old acquaintance in the Android universe.
As we mentioned earlier in TN Technology, Joker is an infamous malware among Android device users. With a history of considerable damage, it hides in applications that simulate various uses. Their actions consist mainly of making automatic subscriptions (without the user’s consent) to paid services.
The intruder also accesses phone notifications which they then silently use to perform SMS verification for the aforementioned subscriptions.

Joker belongs to a family of malware also known as “Pan”, which targets the user’s cell phone bill. Google first identified it in 2017 and has been fighting infected tools ever since, removing them periodically, as happened in this case, which we suspect will be repeated.
As we have noted, all four apps with Prankster were removed from the Google store. If one of them is on your device (already installed), it is urgently necessary to remove it to stop the action of the malicious program.
