KernelSU is going to develop a feature called the "App Profile", which consists of three parts:
1. Root Authorization: granting specified applications access to root permissions 2. Blacklist and Whitelist: providing a list of modules to mount or hide 3. Root Profile
The Root Profile can be used to restrict applications that already have root privileges.
Root permissions can actually be divided into several aspects:
- UID and GID - Groups - Capabilities - SELINUX
In all previous root implementations, permissions in these aspects have been unlimited. This means that a firewall app could format your phone and delete all data, even though it only needed network management privileges; a file manager app could implant viruses, load kernel modules, and hide itself, even though it only needed full file access permissions. There are many similar examples. Imagine hiring a cleaner to tidy up your house, only for them to open your safe and transfer all your possessions away. In fact, most root apps only need a very small subset of root permissions. Why should we grant them unrestricted root privileges?
The Root Profile aims to solve this problem by granting applications restricted root permissions based on appropriate identification, groups, capabilities, and a series of SELinux rules. You can customize the rules yourself or use rules created by others. Of course, if you want to use unrestricted root permissions, there is no problem.
This feature is still in development, and we welcome any feedback and suggestions!

In 2018, Russia banned Telegram although it reversed the prohibition two years later. Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. At its heart, Telegram is little more than a messaging app like WhatsApp or Signal. But it also offers open channels that enable a single user, or a group of users, to communicate with large numbers in a method similar to a Twitter account. This has proven to be both a blessing and a curse for Telegram and its users, since these channels can be used for both good and ill. Right now, as Wired reports, the app is a key way for Ukrainians to receive updates from the government during the invasion. Telegram has gained a reputation as the “secure” communications app in the post-Soviet states, but whenever you make choices about your digital security, it’s important to start by asking yourself, “What exactly am I securing? And who am I securing it from?” These questions should inform your decisions about whether you are using the right tool or platform for your digital security needs. Telegram is certainly not the most secure messaging app on the market right now. Its security model requires users to place a great deal of trust in Telegram’s ability to protect user data. For some users, this may be good enough for now. For others, it may be wiser to move to a different platform for certain kinds of high-risk communications. "Someone posing as a Ukrainian citizen just joins the chat and starts spreading misinformation, or gathers data, like the location of shelters," Tsekhanovska said, noting how false messages have urged Ukrainians to turn off their phones at a specific time of night, citing cybersafety.
