AI getting dangerous: Polish researcher uses ChatGPT-4.o to generate fake passport in 5 minutes!

Artificial intelligence is growing popular day by day in almost every field, but its vast potential is also associated with some significant risks. As AI is continuously evolving, it’s leveling up the industries by improving their efficiencies and generating new possibilities. However, the darker side of this rapid technological progress is the growing potential for misuse. The ability of AI to generate realistic fakes, like IDs and documents, is a prime example of how malicious actors can exploit these advancements.

As we are discovering the boundaries of AI capabilities, it's becoming clear that the consequences are far-reaching, which can also lead to questioning the very foundations of security and trust in our digital world.


Recently, a case has come to the limelight that questions the boundaries of AI's use, a Polish researcher Borys Musielak used ChatGPT-4o , to create a realistic fake passport in just five minutes. The fake document was so convincing that it could easily pass through most automated Know Your Customer (KYC) systems.

Musielak shared this on X, writing , “You can now generate fake passports with GPT-4o. It took me 5 minutes to create a replica of my own passport that most automated KYC systems would likely accept without blinking.” He also emphasised the implications of this breakthrough, suggesting that any verification system relying on photos or selfies is now obsolete, as AI can easily manipulate both static and video images.

The AI-generated passport was so convincing that it bypassed basic KYC checks used by major fintech platforms such as Revolut and Binance. Musielak pointed out the vulnerabilities in current digital identity verification systems, which rely heavily on photo matching. Unlike traditional forgeries, the use of AI made the process much faster and more efficient than older tools like Photoshop.

Tech News reported that Musielak's demonstration is an eyeopener about the rising threat of mass identity theft, fraudulent credit applications, and fake account creation, all of which could now be scaled through generative AI. Musielak urged the need for stricter verification systems, calling for the adoption of NFC-based verification and electronic identity documents (eIDs), which offer stronger, hardware-level authentication.

Within hours of Musielak’s demonstration, ChatGPT began rejecting similar prompts, giving its safety policies against generating fake documents. As Musielak also said, “The only viable path forward is digitally verified identity, like eID wallets mandated by the EU. One of the companies ahead of this shift is our portfolio startup. @authologic. If you’re running KYC in banking, insurance, travel, crypto, or anywhere else — it’s time to upgrade your process. Your users deserve better. So does your compliance team.”
