An worker at Elon Musk’s synthetic intelligence firm xAI leaked a personal key on GitHub that for the previous two months might have allowed anybody to question non-public xAI giant language fashions (LLMs) which seem to have been customized made for working with inside knowledge from Musk’s corporations, together with SpaceX, Tesla and Twitter/X, KrebsOnSecurity has discovered.

Philippe Caturegli, “chief hacking officer” on the safety consultancy Seralys, was the primary to publicize the leak of credentials for an x.ai software programming interface (API) uncovered within the GitHub code repository of a technical workers member at xAI.
Caturegli’s submit on LinkedIn caught the eye of researchers at GitGuardian, an organization that focuses on detecting and remediating uncovered secrets and techniques in public and proprietary environments. GitGuardian’s programs consistently scan GitHub and different code repositories for uncovered API keys, and hearth off automated alerts to affected customers.
GitGuardian’s Eric Fourrier informed KrebsOnSecurity the uncovered API key had entry to a number of unreleased fashions of Grok, the AI chatbot developed by xAI. In complete, GitGuardian discovered the important thing had entry to no less than 60 fine-tuned and personal LLMs.
“The credentials can be used to access the X.ai API with the identity of the user,” GitGuardian wrote in an e-mail explaining their findings to xAI. “The associated account not only has access to public Grok models (grok-2-1212, etc) but also to what appears to be unreleased (grok-2.5V), development (research-grok-2p5v-1018), and private models (tweet-rejector, grok-spacex-2024-11-04).”
Fourrier discovered GitGuardian had alerted the xAI worker in regards to the uncovered API key almost two months in the past — on March 2. But as of April 30, when GitGuardian straight alerted xAI’s safety group to the publicity, the important thing was nonetheless legitimate and usable. xAI informed GitGuardian to report the matter by way of its bug bounty program at HackerOne, however only a few hours later the repository containing the API key was faraway from GitHub.
“It looks like some of these internal LLMs were fine-tuned on SpaceX data, and some were fine-tuned with Tesla data,” Fourrier mentioned. “I definitely don’t think a Grok model that’s fine-tuned on SpaceX data is intended to be exposed publicly.”
xAI didn’t reply to a request for remark. Nor did the 28-year-old xAI technical workers member whose key was uncovered.
Carole Winqwist, chief advertising officer at GitGuardian, mentioned giving doubtlessly hostile customers free entry to non-public LLMs is a recipe for catastrophe.
“If you’re an attacker and you have direct access to the model and the back end interface for things like Grok, it’s definitely something you can use for further attacking,” she mentioned. “An attacker could it use for prompt injection, to tweak the (LLM) model to serve their purposes, or try to implant code into the supply chain.”
The inadvertent publicity of inside LLMs for xAI comes as Musk’s so-called Department of Government Efficiency (DOGE) has been feeding delicate authorities information into synthetic intelligence instruments. In February, The Washington Post reported DOGE officers had been feeding knowledge from throughout the Education Department into AI instruments to probe the company’s applications and spending.
The Post mentioned DOGE plans to copy this course of throughout many departments and businesses, accessing the back-end software program at completely different components of the federal government after which utilizing AI know-how to extract and sift by way of details about spending on staff and applications.
“Feeding sensitive data into AI software puts it into the possession of a system’s operator, increasing the chances it will be leaked or swept up in cyberattacks,” Post reporters wrote.
Wired reported in March that DOGE has deployed a proprietary chatbot referred to as GSAi to 1,500 federal staff on the General Services Administration, a part of an effort to automate duties beforehand performed by people as DOGE continues its purge of the federal workforce.
A Reuters report final month mentioned Trump administration officers informed some U.S. authorities staff that DOGE is utilizing AI to surveil no less than one federal company’s communications for hostility to President Trump and his agenda. Reuters wrote that the DOGE group has closely deployed Musk’s Grok AI chatbot as a part of their work slashing the federal authorities, though Reuters mentioned it couldn’t set up precisely how Grok was getting used.
Caturegli mentioned whereas there isn’t any indication that federal authorities or person knowledge may very well be accessed by way of the uncovered x.ai API key, these non-public fashions are possible skilled on proprietary knowledge and should unintentionally expose particulars associated to inside growth efforts at xAI, Twitter, or SpaceX.
“The fact that this key was publicly exposed for two months and granted access to internal models is concerning,” Caturegli mentioned. “This kind of long-lived credential exposure highlights weak key management and insufficient internal monitoring, raising questions about safeguards around developer access and broader operational security.”
