Internet-Security.com TCP port 2345 details

TCP port 2345 is commonly used by GNU gdbserver, which provides the GDB Remote Serial Protocol for remote debugging.
Many embedded Linux SDKs and vendor boards use gdbserver on :2345 in their official guides and images, including TI Processor SDK Linux (Sitara), NXP i.MX BSPs, and ST’s STM32MP1 OpenSTLinux.
QEMU can expose a GDB debugging endpoint on tcp::2345 (e.g., qemu -gdb tcp::2345), and numerous tutorials connect gdb to :2345.
Developer workflows and IDE integrations that wrap gdb/gdbserver (e.g., VS Code/CLion remote debug setups) often configure the target as host:2345 in examples.
Security note: gdbserver on 2345 has been found exposed on IoT and embedded devices; if reachable, attackers can attach via GDB and achieve code execution with the target’s privileges.
