A Reddit user warned of a sophisticated phishing attack they narrowly escaped. While asking ChatGPT a question, they were almost tricked into pasting a malicious command into the Windows Run dialog.

Investigation revealed that this was caused by a malicious Google Ad. Attackers purchase top ad placements on Google search that direct users to a custom GPT or clone site looking exactly like ChatGPT. This fake interface then injects phishing instructions, attempting to trick users into executing dangerous commands. The disguise is so convincing that even experienced users can fall for it if they aren't paying close attention.
