sysnc

sysnc is a bash wrapper around netcat designed for simplified remote command execution and interactive shell access, particularly on Android devices running Termux. Notably, it can exploit zygote injection (CVE-2024-31317) to establish a system-level shell, allowing for configurable command execution and interaction with a remote server. Key features include an interactive mode with a colored prompt, support for streaming scripts via stdin, and configurable options for host, port, and UID through command-line flags or environment variables.
