Rooting is, in effect, do-it-yourself hacking of the operating system of your tablet or smartphone. Normally, Android apps work in isolated environments in so-called sandboxes and cannot gain access to other apps or the system. However, an app with superuser access rights can venture out of its isolated environment and take full control over the device.
With superuser access rights, apps can do whatever they like — for example, view, modify, or delete files, including those that are required for device operation. After gaining superuser access rights, malicious applications enjoy full freedom. In fact, the first thing many Trojans for Android do is attempt to gain root access. Users rooting their own devices offer quite a gift to malware developers.
Some ransomware Trojans use superuser access rights to improve their chances of staying in the system. In most cases, malware is capable of gaining superuser access rights on its own by exploiting vulnerabilities in the system. But some malware applications use existing permissions. As for Russia, 6. Neither North America nor Western Europe includes any top-rooting countries. And 9 of the 10 countries with the largest number of rooted devices are in the top 25 countries where devices are attacked most often.
Regrettably, although criminals can exploit the advantages of gaining superuser rights and use them to bypass security mechanisms, the good guys still have to play by the rules. Of course, how well malware can take advantage of the capabilities of a rooted system varies. But the risk of a security solution letting a threat through on a rooted device is higher than on a device without superuser access rights.
Using a system with superuser access rights is similar to driving a heavy truck. If you are really capable of handling that, then why not? To help enforce the contract terms, phones may be configured by the carrier so they can only be used on certain networks.
People root smartphones for many reasons. In the early years of Android smartphones, rooting was popular among tech enthusiasts as a way to strip back user interface customizations made by manufacturers to the Android platform. In other instances, the motivation has been to remove preloaded applications. The presence of a Kinguser or Superuser application on the device is an obvious sign the device has been rooted. These applications are typically installed as part of the rooting process to allow access to superuser privileges.
Users can also download a root checker app or a terminal client to determine if superuser access is configured. Any irregularities in the software will be noted. Rooting disables some of the built-in security features of the operating system, and those security features are part of what keeps the operating system safe and your data secure from exposure or corruption.
Quantifying that increased level of risk is hard, because it depends on how the phone was rooted and what happens next.

On the other hand, IT managers know that many users root their phones and then engage in unsafe behaviors, such as installing pirated applications or malware — even unintentionally.
In that case, the security risk rises quickly. Mobile Device Manager Plus scans the device for such apps and if it is present the device is marked as rooted. This is the most accurate rooted device detection method. If either su or sudo commands can be run from the terminal, it means that the device is rooted. Many of the malware created for mobile devices now also have rooting capabilities and using this method we can also detect if a malware has gained the root access of the device.
This condition can be true in 2 cases- if the user has rooted the device or if the OEM has signed the OS build using a test-key instead of a release-key. Though the second case could mean that the device is not rooted by the user or a malware, it is inherently a security risk for organization to use such devices and that is why these devices are also marked as rooted.
