An employee at Elon Musk’s artificial intelligence company xAI leaked a private key on GitHub that for the past two months could have allowed anyone to query private xAI large language models (LLMs) which appear to have been custom made for working with internal data from Musk’s companies, including SpaceX, Tesla and Twitter/X, KrebsOnSecurity has learned.

Philippe Caturegli, “chief hacking officer” at the security consultancy Seralys, was the first to publicize the leak of credentials for an x.ai application programming interface (API) exposed in the GitHub code repository of a technical staff member at xAI.
Caturegli’s post on LinkedIn caught the attention of researchers at GitGuardian, a company that specializes in detecting and remediating exposed secrets in public and proprietary environments. GitGuardian’s systems constantly scan GitHub and other code repositories for exposed API keys, and fire off automated alerts to affected users.
GitGuardian’s Eric Fourrier told KrebsOnSecurity the exposed API key had access to several unreleased models of Grok, the AI chatbot developed by xAI. In total, GitGuardian found the key had access to at least 60 fine-tuned and private LLMs.
“The credentials can be used to access the X.ai API with the identity of the user,” GitGuardian wrote in an email 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 found GitGuardian had alerted the xAI employee about the exposed API key nearly two months ago — on March 2. But as of April 30, when GitGuardian directly alerted xAI’s security team to the exposure, the key was still valid and usable. xAI told GitGuardian to report the matter through its bug bounty program at HackerOne, but just a few hours later the repository containing the API key was removed 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 said. “I definitely don’t think a Grok model that’s fine-tuned on SpaceX data is intended to be exposed publicly.”
xAI did not respond to a request for comment. Nor did the 28-year-old xAI technical staff member whose key was exposed.
Carole Winqwist, chief marketing officer at GitGuardian, said giving potentially hostile users free access to private LLMs is a recipe for disaster.
“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 said. “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 exposure of internal LLMs for xAI comes as Musk’s so-called Department of Government Efficiency (DOGE) has been feeding sensitive government records into artificial intelligence tools. In February, The Washington Post reported DOGE officials were feeding data from across the Education Department into AI tools to probe the agency’s programs and spending.
The Post said DOGE plans to replicate this process across many departments and agencies, accessing the back-end software at different parts of the government and then using AI technology to extract and sift through information about spending on employees and programs.
“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 called GSAi to 1,500 federal workers at the General Services Administration, part of an effort to automate tasks previously done by humans as DOGE continues its purge of the federal workforce.
A Reuters report last month said Trump administration officials told some U.S. government employees that DOGE is using AI to surveil at least one federal agency’s communications for hostility to President Trump and his agenda. Reuters wrote that the DOGE team has heavily deployed Musk’s Grok AI chatbot as part of their work slashing the federal government, although Reuters said it could not establish exactly how Grok was being used.
Caturegli said while there is no indication that federal government or user data could be accessed through the exposed x.ai API key, these private models are likely trained on proprietary data and may unintentionally expose details related to internal development 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 said. “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.”
Wired reported this week that a 19-year-old working for Elon Musk‘s so-called Department of Government Efficiency (DOGE) was given access to sensitive US government systems even though his past association with cybercrime communities should have precluded him from gaining the necessary security clearances to do so. As today’s story explores, the DOGE teen is a former denizen of ‘The Com,’ an archipelago of Discord and Telegram chat channels that function as a kind of distributed cybercriminal social network for facilitating instant collaboration.
Since President Trump’s second inauguration, Musk’s DOGE team has gained access to a truly staggering amount of personal and sensitive data on American citizens, moving quickly to seize control over databases at the U.S. Treasury, the Office of Personnel Management, the Department of Education, and the Department of Health and Human Resources, among others.
Wired first reported on Feb. 2 that one of the technologists on Musk’s crew is a 19-year-old high school graduate named Edward Coristine, who reportedly goes by the nickname “Big Balls” online. One of the companies Coristine founded, Tesla.Sexy LLC, was set up in 2021, when he would have been around 16 years old.
“Tesla.Sexy LLC controls dozens of web domains, including at least two Russian-registered domains,” Wired reported. “One of those domains, which is still active, offers a service called Helfie, which is an AI bot for Discord servers targeting the Russian market. While the operation of a Russian website would not violate US sanctions preventing Americans doing business with Russian companies, it could potentially be a factor in a security clearance review.”
Mr. Coristine has not responded to requests for comment. In a follow-up story this week, Wired found that someone using a Telegram handle tied to Coristine solicited a DDoS-for-hire service in 2022, and that he worked for a short time at a company that specializes in protecting customers from DDoS attacks.

Internet routing records show that Coristine runs an Internet service provider called Packetware (AS400495). Also known as “DiamondCDN,” Packetware currently hosts tesla[.]sexy and diamondcdn[.]com, among other domains.
DiamondCDN was advertised and claimed by someone who used the nickname “Rivage” on several Com-based Discord channels over the years. A review of chat logs from some of those channels show other members frequently referred to Rivage as “Edward.”
From late 2020 to late 2024, Rivage’s conversations would show up in multiple Com chat servers that are closely monitored by security companies. In November 2022, Rivage could be seen requesting recommendations for a reliable and powerful DDoS-for-hire service.
Rivage made that request in the cybercrime channel “Dstat,” a core Com hub where users could buy and sell attack services. Dstat’s website dstat[.]cc was seized in 2024 as part of “Operation PowerOFF,” an international law enforcement action against DDoS services.
Coristine’s LinkedIn profile said that in 2022 he worked at an anti-DDoS company called Path Networks, which Wired generously described as a “network monitoring firm known for hiring reformed blackhat hackers.” Wired wrote:
“At Path Network, Coristine worked as a systems engineer from April to June of 2022, according to his now-deleted LinkedIn résumé. Path has at times listed as employees Eric Taylor, also known as Cosmo the God, a well-known former cybercriminal and member of the hacker group UGNazis, as well as Matthew Flannery, an Australian convicted hacker whom police allege was a member of the hacker group LulzSec. It’s unclear whether Coristine worked at Path concurrently with those hackers, and WIRED found no evidence that either Coristine or other Path employees engaged in illegal activity while at the company.”
The founder of Path is a young man named Marshal Webb. I wrote about Webb back in 2016, in a story about a DDoS defense company he co-founded called BackConnect Security LLC. On September 20, 2016, KrebsOnSecurity published data showing that the company had a history of hijacking Internet address space that belonged to others.
Less than 24 hours after that story ran, KrebsOnSecurity.com was hit with the biggest DDoS attack the Internet had ever seen at the time. That sustained attack kept this site offline for nearly 4 days.
The other founder of BackConnect Security LLC was Tucker Preston, a Georgia man who pleaded guilty in 2020 to paying a DDoS-for-hire service to launch attacks against others.
The aforementioned Path employee Eric Taylor pleaded guilty in 2017 to charges including an attack on our home in 2013. Taylor was among several men involved in making a false report to my local police department about a supposed hostage situation at our residence in Virginia. In response, a heavily-armed police force surrounded my home and put me in handcuffs at gunpoint before the police realized it was all a dangerous hoax known as “swatting.”
CosmoTheGod rocketed to Internet infamy in 2013 when he and a number of other hackers set up the Web site exposed[dot]su, which “doxed” dozens of public officials and celebrities by publishing the address, Social Security numbers and other personal information on the former First Lady Michelle Obama, the then-director of the FBI and the U.S. attorney general, among others. The group also swatted many of the people they doxed.
Wired noted that Coristine only worked at Path for a few months in 2022, but the story didn’t mention why his tenure was so short. A screenshot shared on the website pathtruths.com includes a snippet of conversations in June 2022 between Path employees discussing Coristine’s firing.
According to that record, Path founder Marshal Webb dismissed Coristine for leaking internal documents to a competitor. Not long after Coristine’s termination, someone leaked an abundance of internal Path documents and conversations. Among other things, those chats revealed that one of Path’s technicians was a Canadian man named Curtis Gervais who was convicted in 2017 of perpetrating dozens of swatting attacks and fake bomb threats — including at least two attempts against our home in 2014.

On May 11, 2024, Rivage posted on a Discord channel for a DDoS protection service that is chiefly marketed to members of The Com. Rivage expressed frustration with his time spent on Com-based communities, suggesting that its profitability had been oversold.
“I don’t think there’s a lot of money to be made in the com,” Rivage lamented. “I’m not buying Heztner [servers] to set up some com VPN.”
Rivage largely stopped posting messages on Com channels after that. Wired reports that Coristine subsequently spent three months last summer working at Neuralink, Elon Musk’s brain implant startup.
The trouble with all this is that even if someone sincerely intends to exit The Com after years of consorting with cybercriminals, they are often still subject to personal attacks, harassment and hacking long after they have left the scene.
That’s because a huge part of Com culture involves harassing, swatting and hacking other members of the community. These internecine attacks are often for financial gain, but just as frequently they are perpetrated by cybercrime groups to exact retribution from or assert dominance over rival gangs.
Experts say it is extremely difficult for former members of violent street gangs to gain a security clearance needed to view sensitive or classified information held by the U.S. government. That’s because ex-gang members are highly susceptible to extortion and coercion from current members of the same gang, and that alone presents an unacceptable security risk for intelligence agencies.
And make no mistake: The Com is the English-language cybercriminal hacking equivalent of a violent street gang. KrebsOnSecurity has published numerous stories detailing how feuds within the community periodically spill over into real-world violence.
When Coristine’s name surfaced in Wired‘s report this week, members of The Com immediately took notice. In the following segment from a February 5, 2025 chat in a Com-affiliated hosting provider, members criticized Rivage’s skills, and discussed harassing his family and notifying authorities about incriminating accusations that may or may not be true.

Given the speed with which Musk’s DOGE team was allowed access to such critical government databases, it strains credulity that Coristine could have been properly cleared beforehand. After all, he’d recently been dismissed from a job for allegedly leaking internal company information to outsiders.
According to the national security adjudication guidelines (PDF) released by the Director of National Intelligence (DNI), eligibility determinations take into account a person’s stability, trustworthiness, reliability, discretion, character, honesty, judgment, and ability to protect classified information.
The DNI policy further states that “eligibility for covered individuals shall be granted only when facts and circumstances indicate that eligibility is clearly consistent with the national security interests of the United States, and any doubt shall be resolved in favor of national security.”
On Thursday, 25-year-old DOGE staff member Marko Elez resigned after being linked to a deleted social media account that advocated racism and eugenics. Elez resigned after The Wall Street Journal asked the White House about his connection to the account.
“Just for the record, I was racist before it was cool,” the account posted in July. “You could not pay me to marry outside of my ethnicity,” the account wrote on X in September. “Normalize Indian hate,” the account wrote the same month, in reference to a post noting the prevalence of people from India in Silicon Valley.
Elez’s resignation came a day after the Department of Justice agreed to limit the number of DOGE employees who have access to federal payment systems. The DOJ said access would be limited to two people, Elez and Tom Krause, the CEO of a company called Cloud Software Group.
Earlier today, Musk said he planned to rehire Elez after President Trump and Vice President JD Vance reportedly endorsed the idea. Speaking at The White House today, Trump said he wasn’t concerned about the security of personal information and other data accessed by DOGE, adding that he was “very proud of the job that this group of young people” are doing.
A White House official told Reuters on Wednesday that Musk and his engineers have appropriate security clearances and are operating in “full compliance with federal law, appropriate security clearances, and as employees of the relevant agencies, not as outside advisors or entities.”
NPR reports Trump added that his administration’s cost-cutting efforts would soon turn to the Education Department and the Pentagon, “where he suggested without evidence that there could be ‘trillions’ of dollars in wasted spending within the $6.75 trillion the federal government spent in fiscal year 2024.”
GOP leaders in the Republican-controlled House and Senate have largely shrugged about Musk’s ongoing efforts to seize control over federal databases, dismantle agencies mandated by Congress, freeze federal spending on a range of already-appropriated government programs, and threaten workers with layoffs.
Meanwhile, multiple parties have sued to stop DOGE’s activities. ABC News says a federal judge was to rule today on whether DOGE should be blocked from accessing Department of Labor records, following a lawsuit alleging Musk’s team sought to illegally access highly sensitive data, including medical information, from the federal government.
At least 13 state attorneys general say they plan to file a lawsuit to stop DOGE from accessing federal payment systems containing Americans’ sensitive personal information, reports The Associated Press.
Reuters reported Thursday that the U.S. Treasury Department had agreed not to give Musk’s team access to its payment systems while a judge is hearing arguments in a lawsuit by employee unions and retirees alleging Musk illegally searched those records.
Ars Technica writes that The Department of Education (DoE) was sued Friday by a California student association demanding an “immediate stop” to DOGE’s “unlawfully” digging through student loan data to potentially dismantle the DoE.
