Problem:

macOS (14.2.1) ssh (OpenSSH_9.4p1, LibreSSL 3.3.6) is vulnerable to Terrapin attack (as reported by the scanner).
The regular OpenSSH (e.g. via Homebrew) doesn't support the UseKeychain option

Workaround:

Installation

mkdir -p ~/.config && touch ~/.config/ssh-agent.pid
Paste the contents of ssh-agent-manage.sh into your .bashrc or .bash_profile or similar
killall -9 ssh-agent
Start a new terminal session (note: old sessions will not see ssh-agent, only new ones)

Details

This snippet, when included in .bashrc, will ensure that your session has a working ssh-agent with all your ssh keys loaded into it. It does this without creating separate ssh-agent processes by:

	#!/bin/bash

	# Requesting sudo privileges at the start
	log "Requesting sudo privileges..."

	#!/usr/bin/env bash
