Security researchers found 17 Android apps infected with the Joker (Bread) malware, one of the most notorious security threats Google has been dealing with since 2017. Google Play Store has now removed them this week to prevent WAP billing fraud.
"This spyware is designed to steal SMS messages, contact lists, and device information, along with silently signing up the victim for premium wireless application protocol (WAP) services," said Viral Gandhi, one of Zscaler's security researchers.
Play Store published the 17 malicious apps, which were downloaded more than 120,000 times before the security researchers detected the malware. Here are the names of the applications.

Although Google Play Store has already removed these apps, you still need to intervene and remove the app from your device manually if you downloaded one of them.
How powerful is Joker malware?
The infected apps could easily sneak past Google's defenses and reach the Play Store, using a technique called "droppers," where the user's device is infected in a multi-stage process. Although the cyber attackers' strategy is simple, Google still finds it challenging to deal with it.
The security scans could not easily detect malicious code since the malicious attacks are usually delayed by hours or days. Once a malicious app is installed, it will download and "drop" other apps or components that contain the Joker malware or different malware strains.
What makes this malware notorious is that it can be uploaded by third-party Android app stores, making it more widespread. Security researchers detected more than 13,000 Joker samples ever since it was identified way back in 2016.
