Hacker Stephanie "Snow" Carruthers and her team found phishing emails written by security researchers saw a 3% better click rate than phishing emails written by ChatGPT.

The research project was performed at one global healthcare company based in Canada. In order to get ChatGPT to write an email that lured someone into clicking a malicious link, the IBM researchers had to prompt the LLM. They asked ChatGPT to draft a persuasive email taking into account the top areas of concern for employees in their industry, which in this case was healthcare.
Microsoft has disabled a bad anti-spam rule flooding Microsoft 365 admins' inboxes with blind carbon copies of outbound emails mistakenly flagged as spam.
