A 15-year-old in Japan just showed the entire security industry its next problem. 🤯

He found the vulnerability the old-fashioned way, studying Bandai Channel's network traffic by hand. That part isn't new. What's new is what happened after. He handed the exploit to ChatGPT and had it write the program that automated 46,812 account cancellations. When Bandai Namco tried to block him, he rotated his IP roughly 30 times and kept going.
The company had to take the entire platform offline for a month. Member emails and nicknames were exposed in the process.
He told police he had no grudge against the company. He just had access and a tool that removed the only bottleneck that used to matter, which is the time it takes to turn a discovered flaw into working code.
That bottleneck is gone now. Vulnerability discovery is still a skill. Exploitation is turning into a prompt.
