OpenAI’s official press account on X was compromised on September 23, marking the fifth cybersecurity breach linked to the firm since January 2023.
Hackers used the account to promote a phishing scam involving a fake "OPENAI" token, urging users to claim tokens for access to future beta programs.
The malicious posts have since been removed from the account.
The breach was first noticed by X users at around 10:26 p.m. UTC, with many pointing out that the posts shilling "OPENAI" tokens were not from the real OpenAI team.
Screenshots revealed that the hackers had posted links to a website labeled as a phishing site, warning users who tried to access it.
Benjamin De Kraker, a developer at Grok, highlighted the hack, stating, "The official OpenAI Newsroom account has been hacked and is shilling fake shitcoins."
Users attempting to claim the tokens were met with a phishing warning on the associated website, which has been flagged for suspicious activity.
OpenAI has not yet publicly addressed the incident.
This is not the first time OpenAI has been targeted.
Since June 2023, there have been three other hacks involving X accounts tied to OpenAI employees, including Chief Scientist Jakub Pachocki and CTO Mira Murati.
All the incidents involved similar attempts to promote fake "OPENAI" tokens.
In addition to these account breaches, OpenAI was also hit by a separate hack in early 2023 that compromised an internal forum, allowing attackers access to proprietary information and employee data.
Fortunately, core systems and code remained unaffected in that breach.
