OpenAI Reportedly Hacked Last Year, Didn't Tell Anyone About It

OpenAI declined to inform the FBI or law enforcement because executives believe the hacker is a private individual rather than a member of a state-sponsored hacking group.

ChatGPT developer OpenAI reportedly suffered a breach last year involving a hacker who stole details about the company’s systems. 

The hacker infiltrated an internal OpenAI forum where employees chat about the company’s technology, according to The New York Times, citing two sources familiar with the incident. The attacker did not gain access to systems where OpenAI houses or builds its AI models. 

The company told employees about the hack in April 2023 but refrained from notifying the public since no data from customers or partners was stolen. The Times also says OpenAI declined to inform the FBI or law enforcement about the breach because executives believe the hacker is a private individual rather than a member of a state-sponsored hacking group. 

OpenAI didn’t immediately respond to a request for comment. But the reported breach may explain why it hired former NSA director Paul Nakasone to sit on the company’s board.

Critics, including former NSA leaker Edward Snowden, condemned the hiring over concerns that OpenAI will secretly partner with the US government to spy on users. However, OpenAI has said the Nakasone hiring is about bolstering the company’s cybersecurity. This includes protecting its supercomputers and the company’s “sensitive model weights,” which define how OpenAI’s models work. 

Still, others question why OpenAI didn’t inform the public since it collects massive amounts of user data through ChatGPT and its APIs. "Company executives decided for themselves that it wasn't a national security threat?” tweeted John Scott-Railton, a researcher at surveillance watchdog Citizen Lab. “Bright red flag as company races to accumulate data and power.”

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
