In August 2021, Tokio Marine Insurance Singapore Ltd. (TMiS), a subsidiary of the Tokio Marine Group, experienced a ransomware attack. The intrusion was detected early, prompting immediate containment measures, including network isolation to prevent further spread.

Despite the attack, no evidence was found of customer data breaches or leaks of confidential company information. The incident remained localized to TMiS, with no reported impact on other entities within the Tokio Marine Group. The swift response mitigated potential damage, ensuring no financial, reputational, or operational consequences beyond the initial intrusion.
