This post was updated throughout on Thursday, Feb 9, to make clear that the method used to bypass ChatGPT restrictions is employing APIs for a GPT-3 model known as text-davinci-003 instead of ChatGPT. Both text-davinci-003 and ChatGPT are GPT-3 models (OpenAI later distinguished them as GPT-3.5 models.) ChatGPT is specifically designed for chatbot applications and has been fine tuned from GPT-3.5 models.

Hackers have devised a way to bypass ChatGPT’s restrictions and are using it to sell services that allow people to create malware and phishing emails, researchers said on Wednesday.

ChatGPT is a chatbot that uses artificial intelligence to answer questions and perform tasks in a way that mimics human output. People can use it to create documents, write basic computer code, and do other things. The service actively blocks requests to generate potentially illegal content. Ask the service to write code for stealing data from a hacked device or craft a phishing email, and the service will refuse and instead reply that such content is “illegal, unethical, and harmful.”

Opening Pandora’s Box

Hackers have found a simple way to bypass those restrictions and are using it to sell illicit services in an underground crime forum, researchers from security firm Check Point Research reported. The technique works by using the application programming interface for one of OpenAI’s GPT-3  models known as text-davinci-003, instead of ChatGPT, which is variant of the GPT-3 models that’s specifically designed for chatbot applications. OpenAI makes the text-davinci-003 API and other model APIs available to developers so they can integrate the AI bot into their applications. It turns out the API versions don’t enforce restrictions on malicious content.

“The current version of OpenAI’s API is used by external applications (for example, the integration of OpenAI’s GPT-3 model to Telegram channels) and has very few if any anti-abuse measures in place,” the researchers wrote. “As a result, it allows malicious content creation, such as phishing emails and malware code, without the limitations or barriers that ChatGPT has set on their user interface.”

A user in one forum is now selling a service that combines the API and the Telegram messaging app. The first 20 queries are free. From then on users are charged $5.50 for every 100 queries.
