GMO Internet says suspected attackers published information claimed to concern the company and its customers at 12:30 p.m. JST on October 27 following the Onamae.com Desktop Cloud breach. The company is still checking authenticity and the scope of customer information and warns that inaccurate material may be included. Publication is a material development beyond the previously reported service breach and compensation plans. Customers should rely on official notices rather than visit leak sites, and reject requests for recovery fees, passwords or verification codes. The company had not confirmed a ransomware attack in that day’s update.
