Grand Theft Auto VI, widely heralded as the game event of the decade, took a significant hit last week after a cybercriminal sent much of the internet into pandemonium after publishing gameplay footage a week before the game’s publisher planned to reveal core portions of the game to the public.  

The files posted by the online persona “CyberLeek” indicate either a hacker had direct access to Rockstar Games’ most sensitive systems or was given proprietary data by an insider, eventually becoming one of the highest-profile data extortion attacks of the year — a vexing, almost-daily occurrence hitting industries of all types.

While most data extortion attacks rattle companies due to regulatory or privacy concerns, this particular incident has caused an outsized response from Rockstar’s parent company, Take-Two Interactive Software, because it has an audience. While no lives are at risk, as they would be in an attack on critical infrastructure, the financial and reputational stakes are magnified precisely because people are watching every drip of stolen footage become a news story or a trending topic. 

“IP theft — whether it’s conducted by a cybercriminal, an insider, or even potentially [an artificial intelligence] model — rips away the hard work, passion, and livelihood among employees and companies that created the product in the first place,” Cynthia Kaiser, senior vice president of Halycon’s ransomware research center, told CyberScoop.

The game’s prior release, GTA V, along with its online component, has sold over 230 million copies and earned Take-Two over $11 billion since its release in 2013. Industry analysts say GTA VI is on pace to make between $3.3 billion to $5.2 billion in cumulative global sales by the end of its launch week in November. 

“The crown jewels of a company are whatever makes it differentiated and special,” said Kaiser, the former deputy assistant director of the FBI’s cyber division. “For some, that means customer data or source. For a studio in the final stretch before launch, the crown jewel is the surprise.”

While Take-Two hasn’t said anything publicly about the leaks, it has responded feverishly via its legal team. The company petitioned a federal court for subpoenas under the Digital Millenium Copyright Act against Discord, Google, Microsoft and X, seeking the identity of CyberLeeks and other user accounts it accuses of copyright infringement.

Federal judges granted the subpoenas against Discord, Microsoft and X, but the petition against Google remained unapproved as of Monday. Take-Two’s legal representatives also sent copyright notices to the four companies, informing them of the copyrighted material published on their platforms, but it’s unclear if any of the tech companies have been formally served with the signed subpoenas. 

Take-Two and Rockstar did not respond to a request for comment.

The subpoenas may have been enough to spook those responsible for the leaked footage. As of Monday, the websites where those behind CyberLeek were posting leaked information and links to a memecoin were offline.

Zach Edwards, staff threat researcher at Infoblox and a self-proclaimed fan of the series, initially thought the leaks were part of a Rockstar guerrilla marketing campaign. But the company’s response “confirms that this is a real investigation, and the content being shared is likely real to some degree,” he said. 

Take-Two’s actions thus far indicate the company is approaching the breach and leaks like an insider threat investigation, Edwards said. Whoever leaked the footage may have had access to an actual build of the game, he added. That could point to an insider, someone who could have saved a copy to a cloud service, uploaded it to a file-hosting site, or walked out with it on an external drive.

CyberLeek’s conflicting motivations

The hacker or group behind CyberLeek claim they are releasing the gameplay videos to protest Rockstar’s decision to not release physical copies of the game. Yet, watermarks on the leaked videos include addresses to crypto wallets, which indicate CyberLeek is also, and perhaps primarily, seeking a payout. 

“The persona behind the leaks, CyberLeek, published an anti-corporate manifesto targeting digital pre-orders and disc-less releases to frame the breach as hacktivism,” Ben Bernstein, manager of Huntress’ cybersecurity advisors team, told CyberScoop. “Yet behind the political posturing, there’s clear financial monetization and clout-chasing.”

Kaiser draws the same conclusion. “Let’s separate stated motive from observed behavior,” she said. “Threat actors who talk about principle while running a monetization channel are usually only telling you what they think will land with an audience, not actually what is driving them.”

Katie Moussouris said “this is what the alternative vulnerability economy looks like.” The founder and CEO at Luta Security has spent decades building legitimate channels for people who find security problems to get paid without turning to crime.

“The leaker launched a cryptocurrency token, watermarked stolen footage with a buy link, and offered to sell ad space on future leaks. Each of those pays out in proportion to how many people are watching. The manifesto is what keeps them watching,” Moussouris said. 

“That is a genuinely new monetization model for stolen pre-release content, and it means the usual playbook of negotiating a ransom payment quietly or paying to make it stop won’t work,” she added.

Different flavor, same crime

Despite its unique characteristics, the rhythm of the attack and its fallout is familiar territory for cybersecurity experts. 

“Steal, publish a sample, promise more, deliver, repeat. Just like ransomware attacks, in cases like these criminals use every lever of pressure they can against a company — including the fear of what is coming next — to profit from their actions,” Kaiser said. 

“The attackers are crowdsourcing their pressure tactics. A meaningful share of the player base is treating the leaks as free content and amplifying them,” she added.

Kaiser also sees some clear parallels with previous attacks targeting major entertainment companies, including the 2014 attack on Sony Pictures and the HBO hack in 2017. 

“The Sony comparison is useful for how these things escalate, but this incident reminds me more of the Iranian hackers’ leak of ‘Game of Thrones’ episodes a few years back,” she said. “North Korea attacked Sony for political purposes, destroying its data along the way; Iranian threat actors compromised HBO, along with hundreds of universities and over forty other companies, in a hacking-for-hire scheme stealing American intellectual property.”

Federal authorities earlier this month unsealed a second wave of indictments against 17 Iranians affiliated with the tech firm Mabna Institute who allegedly stole troves of data from government agencies and dozens of companies, including HBO.

This isn’t the first time Rockstar has been hit with a security incident. In 2022, an 18-year old British man who was a member of the Lapsus$ cybercriminal gang was sentenced to an indefinite hospital order after leaking gameplay footage. According to the BBC, the incident cost Rockstar, along with ridehauling company Uber and chipmaker NVidia, over $10 million. 

The subpoena that worries security experts

Security professionals expect the situation to escalate on all sides. Leaks have hit the internet daily for the past eight days, including a series of leaks Tuesday morning. Meanwhile, Take-Two has not relented on its subpoenas. Its broadest move was a subpoena against Discord, seeking identifying data on CyberLeek, two other users and every member of three Discord servers where the copyrighted material was posted.  

Moussouris said the scope of that inquiry should worry people well beyond this case. 

“Take-Two asked for Windows device identifiers, login records, and cloud storage contents for every person who spoke in three Discord servers going back to June,” she said. “The people with the best chance of uncovering the culprits are those doing the unglamorous investigation forensics work of figuring out how the build may have leaked.”

Discord would not say whether it had been formally served or what it has done in response. A company spokesperson said it reviews and complies with valid subpoenas when they are received. 

While the breach and leak of ‘GTA VI’ material is a serious matter, Edwards noted that Take-Two is also benefiting from greater interest in the unreleased game on a daily basis. 

“The threat actor leaking these videos has failed by essentially creating a successful underground marketing campaign for the game while also putting themselves at serious risk of being eventually caught,” he said. 

“This incident is playing out like a classic insider threat exploitation scheme. Someone got access to sensitive data, they had a political agenda which clashed with the owner of the sensitive data, and they decided to do something stupid to try and force a change,” Edwards added. “This attack has done nothing but spread ‘GTA VI’ content further than it would have otherwise, and it’s creating ripples across other industries like cybersecurity who would have never covered ‘GTA 6’ issues previously.”
