The Singapore office takes on claim surveys, mainly for corporate cargo and hull insurance, from several insurers including a subsidiary of Mitsui Sumitomo Insurance. Mitsui Sumitomo Insurance said customer information might have leaked and had a third-party body investigate. The association is running a forensic investigation with a specialist firm. The extent of the damage was not known when the case was announced. No cyberattack was found at the association's other overseas offices, local companies, or headquarters and offices in Japan.
