Japanese Internet services group GMO apologized on Monday for recent security breaches resulting from cyber attacks, pledging to prevent their recurrence and to compensate those affected. During a press conference in Tokyo, CEO Masatoshi Kumagai and other senior executives of the group bowed out, according to Japanese tradition, after the hack led to the leakage of information and the execution of transactions that affected dozens of securities companies and other companies, with a total of more than 26 thousand cases.
