It seems the culprit behind the massive leak may be a 17-year-old based in London, though little about the hacker's identity is known at the time.

The FBI was reportedly conducting an investigation into the attack and had knowledge that it was done by someone who goes by the online alias "White" and is apparently a member of the known hacking group Lapsus$. The hacker's recent attack was also allegedly extended to Uber Technologies.

On the morning on Sept. 23, the City of London police tweeted that it had apprehended a 17-year-old "on suspicion of hacking, as part of an investigation supported by the... National Cyber Crime Unit (NCCU)."

Though the City of London police did not confirm that this arrest was made in relation to the hacking at Rockstar Games, journalist Matthew Keys later tweeted confirmation that the suspect was allegedly behind the GTA VI leak.

At this time, as the suspect is a minor, no information on their name or gender has been released. As the proceedings continue to move forward, it's likely more information on the hacker will come to light.
