Go : File permission manipulation

The application changes the file access permissions. The extra permissions (e.g., the right to execute) for an unlimited number of users can facilitate the organization of the attack.

Unix-like systems use the commands MkdirAll, OpenFile, Chmod for rights management. Here, the “file” is understood in a broad sense - file, directory, socket, symbolic link, etc. For each file there are three groups of users: the file owner (user), the group to which the file owner belongs (group) and the rest (other). Each group can have the following access rights: read, write, and execute (abbreviated as r, w, and x, respectively).
