reverse-shell:
  label: Reverse shell
  description: It can send back a reverse shell to a listening attacker to open a remote network access.

non-interactive-reverse-shell:
  label: Non-interactive reverse shell
  description: It can send back a non-interactive reverse shell to a listening attacker to open a remote network access.

bind-shell:
  label: Bind shell
  description: It can bind a shell to a local port to allow remote network access.

non-interactive-bind-shell:
  label: Non-interactive bind shell
  description: It can bind a non-interactive shell to a local port to allow remote network access.

file-upload:
  label: File upload
  description: It can exfiltrate files on the network.

file-download:
  label: File download
  description: It can download remote files.

file-write:
  label: File write

library-load:
  label: Library load
  description: It loads shared libraries that may be used to run code in the binary execution context.

suid:
  label: SUID
  description: It runs with the SUID bit set and may be exploited to access the file system, escalate or maintain access with elevated privileges working as a SUID backdoor. If it is used to run `sh -p`, omit the `-p` argument on systems like Debian (<= Stretch) that allow the default `sh` shell to run with SUID privileges.

sudo:
  label: Sudo
  description: It runs in privileged context and may be used to access the file system, escalate or maintain access with elevated privileges if enabled on `sudo`.

capabilities:
  label: Capabilities
  description: It can manipulate its process UID and can be used on Linux as a backdoor to maintain elevated privileges with the `CAP_SETUID` capability set. This also works when executed by another binary with the capability set.

limited-suid:
  label: Limited SUID
  description: It runs with the SUID bit set and may be exploited to access the file system, escalate or maintain access with elevated privileges working as a SUID backdoor. If it is used to run commands it only works on systems like Debian (<= Stretch) that allow the default `sh` shell to run with SUID privileges.
