Hackers often spare no effort in coming up with new ways to achieve their duplicitous ends, and some could very well use ChatGPT with such unscrupulous intent.
With cleverly written prompts, they may indeed be able to obtain the passwords of some individuals, at least those who have chosen something related to their own life (date of birth, children’s names, pets, etc.) as a source of inspiration.
Computer security specialists, like Check Point, have already tested the approach. In fact, just by giving information about someone, or referring to their online biography, ChatGPT is able to imagine examples of passwords that this person could use based on their life, hobbies, preferences, jobs, etc.
Fortunately, ChatGPT isn’t fooled by direct requests of this type, responding with answers like “I’m sorry, but it would be inappropriate and potentially dangerous to suggest or guess passwords that this person might use to access their online account.”
However, an artificial intelligence specifically dedicated to password cracking has been available on GitHub for a few years now. PassGan has been fed with machine learning from a database of several hundred million passwords.
The cybersecurity specialists at Home Security Heroes have also put together a tool that shows, in theory, how long it would take an artificial intelligence to crack a password. Depending on its complexity, it could take from a few seconds to several billion years!
So far, it has been found that around half (51%) of “classic” passwords can be cracked in less than a minute, 35% in less than an hour, and 71% in less than a day. The more complex the chosen password is, the longer it will take to crack, even for a well-trained artificial intelligence.
To summarize, beyond 10 characters mixing lowercase, uppercase, numbers, and special characters, you are relatively safe.
But in any case, double authentication, which consists of validating access to your account via a code provided by SMS, email, or a dedicated app, will prevent anyone from approaching your data, even after successfully cracking your password via ChatGPT or otherwise.
