Attackers omit destination URLs from visible posts and instead embed them in the small "From:" field under video cards, which X apparently does not scan. By prompting Grok with queries like "where is this video from?", actors get the assistant to repost the hidden link as a clickable reference, effectively legitimizing and amplifying scams, malware distribution, and deceptive CAPTCHA schemes across the platform.
