A study of 150,000 apps found that the Android system is as secure as nothing

Recently, a study from Ohio State University, New York University and the Helmholtz Center for Information Security showed that thousands of Android apps have hidden backdoors, posing security risks.

The sample for this study is massive, including 100,000 of the most popular apps on Google Play, 20,000 apps from Baidu Store, and 30,000 apps pre-installed on Samsung phones, totaling 150,000 apps.

The study found that among these 150,000 apps, as many as 13,000 apps have backdoors that can secretly access keys and master passwords. In addition, 4,000 apps have blacklist systems.

The study showed that 7% of Google Play Store apps showed the presence of backdoors, while 5.3% of Baidu Store apps had backdoors.

The researchers also selected 30 apps with more than 1 million installations and found that one of them allowed remote login.

In other words, a considerable number of Android apps pose security risks, not to mention the common problem of abuse of permissions.

However, Google is not indifferent. Google Play is ruthless towards malware and will remove it as soon as it is found. Google also continues to add a one-time permission design in new Android versions, such as Android 11, which allows users to authorize certain permissions of APP (such as location, phone calls, etc.) at a time.
