How Can ChatGPT be Used Maliciously?
Recently, researchers from Check Point Software discovered that ChatGPT could be utilized to create phishing emails. When combined with Codex, a natural language-to-code system by OpenAI, ChatGPT can develop and disseminate malicious code.
According to Sergey Shykevich, threat intelligence group manager at Check Point Software, “Our researchers built a full malware infection chain starting from a phishing email to an Excel document that has malicious VBA [Visual Basic for Application] code. We can compile the whole malware to an executable file and run it in a machine.”
He adds that ChatGPT primarily produces “much better and more convincing phishing and impersonation emails than real phishing emails we see in the wild now.”
In regards to the same, Lorrie Faith Cranor, director and Bosch Distinguished Professor of the CyLab Security and Privacy Institute and FORE Systems Professor of computer science and of engineering and public policy at Carnegie Mellon University says, “I haven’t tried using ChatGPT to generate code, but I’ve seen some examples from others who have. It generates code that is not all that sophisticated, but some of it is actually runnable code[…]There are other AI tools out there for generating code, and they are all getting better every day. ChatGPT is probably better right now at generating text for humans, and may be particularly well suited for generating things like realistic spoofed emails.”
Moreover, the researchers have also discovered hackers that create malicious tools like info-stealers and dark web markets using ChatGPT.
What AI Tools are More Worrisome?
Cranor says “I think to use these [AI] tools successfully today requires some technical knowledge, but I expect over time it will become easier to take the output from these tools and launch an attack[…]So while it is not clear that what the tools can do today is much more worrisome than human-developed tools that are widely distributed online, it won’t be long before these tools are developing more sophisticated attacks, with the ability to quickly generate large numbers of variants.”
Furthermore, complications could as well arise from the inability to detect whether the code was created by utilizing ChatGPT. “There is no good way to pinpoint that a specific software, malware, or even phishing email was written by ChatGPT because there is no signature,” says Shykevich.
What Could be the Solution?
One of the methods OpenAI is opting for is to “watermark” the output of GPT models, which could later be used to determine whether they are created by AI or humans.
In order to safeguard companies and individuals from these AI-generated threats, Shykevich advises using appropriate cybersecurity measures. While the current safeguards are still in effect, it is critical to keep upgrading and bolstering their application.
“Researchers are also working on ways to use AI to discover code vulnerabilities and detect attacks[…]Hopefully, advances on the defensive side will be able to keep up with advances on the attacker side, but that remains to be seen,” says Cranor.
While ChatGPT and other AI-backed systems have the potential to fundamentally alter how individuals interact with technology, they also carry some risk, particularly when used in dangerous ways.
“ChatGPT is a great technology and has the potential to democratize AI,” adds Shykevich. “AI was kind of a buzzy feature that only computer science or algorithmic specialists understood. Now, people who aren’t tech-savvy are starting to understand what AI is and trying to adopt it in their day-to-day. But the biggest question, is how would you use it—and for what purposes?”
