Beware android users installing apps from Play Store may wipe entire data of your phone or malware can cause harm to your device. According to A University of Michigan study found 410 Android apps in the Google Play store with open ports. Those 410 apps can be exploited in 956 different ways.
The University of Michigan team built a program called OPAnalyzer, described as “a static analysis tool which can effectively identify and characterize vulnerable open port usage in Android applications,” which it used to find open ports. The researchers then manually tested 57 apps to confirm what they suspected.

The report didn’t list any of the vulnerable apps, and with good reason: 50% of those discovered have more than 500,000 downloads.
Smartphones connected to the Internet via wireless network behind a router are less impacted by this issue, because in that case, attackers would need to be on the same wireless network as the victim.
Open ports don’t mean much if you don’t know what they’re used for and how that use can be exploited. The research team found that 99% of traffic on reachable open Android app ports.
Infosec professionals have a whole other list of problems stemming from vulnerable apps that are already installed.
