01
Background & Context
GMO Internet Group, a major Japanese internet services provider, has been confronting an alleged hacker group that posted personal data of its customers on a public website. The hackers warned that, unless a $1 million ransom was paid by noon on Tuesday, they would release additional compromised accounts each day. After GMO refused the demand, the group posted the information of at least one customer before the site was taken down.

Official Statements & Responses
GMO’s chief executive, Masatoshi Kumagai, announced that the company’s cybersecurity team uncovered critical clues that could help identify the perpetrators. The firm submitted this intelligence to police and other relevant authorities to facilitate a swift arrest or the issuance of an international wanted notice. GMO also warned that visiting the illicit site could result in further data collection and urged anyone who had accessed it to run a full antivirus scan. The company said it would pursue decisive legal action, including criminal complaints, against anyone who spreads the data, creates counterfeit sites, or impersonates GMO.
The Internal Affairs and Communications Ministry intervened by asking telecommunications carriers, through industry bodies, to block any sites that continue to host the leaked personal information.

Data & Statistics

- The bounty will remain in effect for one year or until the perpetrators are apprehended.

- The hacker group had previously claimed to have obtained vulnerability details from an external source via an online contact form, but GMO did not respond.

Potential Impact
The bounty and government blocking order illustrate a coordinated effort between the private sector and Japanese authorities to combat large-scale data breaches. By incentivizing tip submissions and restricting access to leaked sites, GMO aims to limit further exposure of customer data and deter future extortion attempts. The case also highlights the challenges companies face when balancing ransom negotiations against legal and security considerations.
