An endemic malware

Since 2017, Google has been trying to improve its malware detection system to take down Joker, but they seem to have met his match. The team behind Joker he modifies it frequently to get around the Google Play Protect controls. In addition, according to Google, it is a very prolific team, capable of sending dozens of infected applications to the Google store in a single day.

The detection of Joker has other difficulties, and it is that applications are submitted to Google Play for review “clean”, and it is not until later when they are updated with the “viral load”, either as updates to Google Play or as an update as soon as the application is opened. All this trying to stand out in the app store through fake reviews and / or incentivized downloads in other apps.

Rather than come back, the Joker malware has arguably never left Google Play

The result is a perfect storm in which the most accurate thing is not to say that the Joker returns, but that he has never left. In the arms race between Google and Joker, the bad guys seem to be winningWell, we’ve seen it back on Google Play over and over again. Google is capable of filtering a good part of the malware (last year they claimed to have killed more than 1,000 applications with the malware), but the villain continues to appear, time and time again.

Without tighter control of the Android ecosystem and a more thorough review of the apps before and after they hit the store, it looks like Joker is going to have a good season with us. However, it is estimated that almost 4,000 applications are uploaded every day new to Google Play, so the percentage of infection remains low, although never zero.
