In the name of fake and legitimate application tool apps or game apps, it is actually a malicious fraudulent activity with advertising intrusion. These malicious deceptive methods are constantly being introduced and new ones are introduced from time to time.

In addition to being listed on the Google Play Store from time to time, even the Apple App Store, which has always been more rigorous, has also suffered.

According to a recent security report released by Human Security, a foreign-invested security company, it was found that the two major application store platforms, Google Play and App Store, were covered, including 9 iOS models and 80 Android models. A total of 89 apps (click here for a complete list), with a total of over 13 million downloads worldwide, were infected with a new type of malicious fraud program called "Scylla".

After reporting, the above-mentioned 89 apps have been removed from the two major app store platforms and have been forcibly deleted.

However, if the mobile phone has previously downloaded the 89 apps identified this time, it must be manually deleted on the mobile device to avoid the intrusion and interference of malicious advertisements in the future.
