One of the characteristics of Android system is openness. In addition to enjoying rich application programs, consumers can also deeply transform the system through root and customized ROM, which greatly improves the playability of the system. But with Google stepping up its efforts to protect the Android platform, the era of cracking and root may come to an end.
But Google's latest safetynet could end that. Safetynet is a set of Google play services APIs that applications can use to verify that the phone is compromised in terms of security. This is critical for applications such as banking and financial applications, but also for applications that don't really need it.
rooting frameworks like Magisk used to be able to use the same API to bypass these API, and tell apps that phones are not being root.. And in the latest version, this behavior has become very difficult.
According to senior developers, safetynet has quietly begun to use hardware certificates to check the integrity of devices. It will verify many factors, including bootloader unlock status, whether there is root program, signed firmware, etc. to check the status of the phone. In other words, it's hard to hide a mobile phone after it's root.
It needs to be clear that users can still root Android devices or install custom ROM. However, with the new safetynet, users will have to choose between these super user features and being able to use some popular and important Android applications.
