Security threats are always ongoing, and although Google does its best to prevent malware from affecting Android users, there are many threats that are impossible to stop every day, so Google always recommends installing apps only from Google Play directly, and it also took time To explain how one of the most dangerous malware works in recent months so users know when they are infected.
As Google made clear in its official blog about some malware-caused scams, Joker is one of the malware that tried to affect users, and there were already many victims of this malware.
The first time that Google discovered this malware was in 2017, it managed to trick users into subscribing to the premium SMS service, thus stealing their money without knowing what was really going on.
Google took action on this issue and was able to prevent Joker from continuing to use the premium SMS service, so try the popular WAP Billing Scam, which for those who don't know what a WAP bill is, that telecom companies use so that we can subscribe to the service Or pay for an item that is then charged to our phone bill.
Since then, Joker officials have not changed the method, but Google has reported that it has already removed 1700 apps containing this malware before downloading by users, part of that effort is due to Google Play Protect.
According to the company, the first thing that this malware does is launch a clean copy in the Google Play Store, then it raises false positive reviews and ratings about the app for people to encourage them to download it, and once users start downloading, the developer starts an update that already contains malware .
Google is constantly reviewing app updates in the Google Play Store and has been able to eliminate malware that has been able to move to its store.
Google has also reported that Joker administrators usually post up to 23 different apps daily, rest a week, and then start updates with malware.
The company requires users to pay attention to billing through their carrier.
