A report from a Google security team said that millions of Android smartphones are pre-loaded with malicious and malicious software from the factory.
This is the first time that such a phenomenon is detected. According to previous reports, there are millions of malicious apps on the Google PlayStore.
The new warning poses a greater risk as buyers purchase these smart devices and make sure they are free of malicious and harmful applications.
The danger is that some of these pre-installed malware can download other malware in the background, perform advertising scams or even control the host machine (for applications).
According to Google's security report, new phones can hold up to 400 apps installed. Note that many of these applications have not been reviewed, as the security team has found.
Google's Madi Stone, Project Zero's security researcher, presented her team's findings at the Black Hat Vulnerability Detection Conference.
"If harmful applications are pre-installed applications, the damage they can cause is even greater, and that's why we need a lot of analysis, analysis and analysis," warned Stone.
However, the warning does not apply to major manufacturers of complete Android devices, such as Samsung and Google, but to companies that use the less open source Android system, according to Sky News.
Despite this warning, the Google team did not disclose any details about the names of the smartphones involved, knowing that there are more than 200 device manufacturers that failed the tests, which allowed malicious software to attack remote devices.
Chamois and Triada are examples of malicious applications. They generate many misleading ads, install applications in the background, download plug-ins, and send paid text messages without user authorization.
