Reports have surfaced regarding a potential data breach at OpenAI, with claims suggesting that 20 million user accounts may have been compromised. The cybercriminal known as "emirking" claimed to have stolen the login credentials and put them up for sale on a dark web forum, even sharing samples of the supposed stolen data. Early investigations indicate that the compromised credentials did not originate from a direct breach of OpenAI's systems.

Instead, cybersecurity researchers believe the credentials were harvested through infostealer malware, which collects login information from various sources on infected devices. Security experts suggest that the extensive credential theft may have been achieved by exploiting vulnerabilities or securing admin credentials. OpenAI is currently investigating the incident. Users are urged to change their passwords and enable multi-factor authentication.
