GMO Internet Group held a press conference on November 2, 2026, to apologize for a data leak caused by unauthorized access to Onamae.com Desktop Cloud, which is run by subsidiary GMO Internet. Partway through, group president Masatoshi Kumagai stopped an executive answering a question to point out that his jacket was unbuttoned.
The breach at Onamae.com Desktop Cloud let someone obtain users' securities account login details without authorization, and information believed to be personal data was made public. Separately, GMO GlobalSign said on October 30 that a configuration error had left information at GMO Trust Login viewable from outside for about nine years.
Kumagai opened the conference with an apology. "I offer my heartfelt apologies to the customers and everyone involved who have been affected," he said. He said the group had been warned in advance about problems in its systems and had failed to put those warnings to use in running its services.
He also apologized for his own social media activity, including a photo of himself smiling that he posted to X.
Asked about the GMO Trust Login leak, Kumagai said the matter should have raised alerts through vulnerability assessments and similar checks. The group would investigate why it was not resolved, he said, then handed over to the responsible executive at GMO GlobalSign to give an accurate answer.
Kumagai cut in as the executive began to speak. "Hold on a moment," he said, and told him to do up his jacket. "Button your jacket properly. You're apologizing, what are you doing with your jacket open?" He then apologized to the reporters in the room.
The executive buttoned his jacket and explained what had happened since the configuration error came to light. He said countermeasures are being pursued with a target of November 30.
