Japan’s GMO Internet Offers $1M Bounty After FX Trading Cloud Breach

Japan’s GMO Internet Group has announced a reward programme offering up to $1 million (£820,000) for information leading to the arrest of attackers who breached its Onamae.com Desktop Cloud service. The move follows the company’s refusal to comply with an extortion demand from the cybercriminals.

The bounty programme, which opened on 28 October 2026, seeks to identify and apprehend the individuals responsible for the intrusion. The Onamae.com Desktop Cloud service provides Windows desktop environments primarily used by clients for foreign exchange (FX) trading activities.

GMO Internet Group specified that the reward will only be paid if a tip directly assists law enforcement in securing an arrest or an international wanted notice for the perpetrators. The company has taken a firm stance against negotiating with cybercriminals, opting instead to leverage public assistance to bring the attackers to justice.

Details regarding the specifics of the breach, such as the exact date of the incident or the types of data potentially compromised, were not immediately disclosed. However, the decision to offer a substantial bounty underscores the severity of the incident and GMO Internet Group’s commitment to holding the attackers accountable.
