Event summary

Trio-Tech International, a semiconductor services firm, experienced a ransomware attack on its Singapore subsidiary where files were encrypted and data was stolen and published online by the Gunra ransomware group. Initially deemed immaterial by Trio-Tech, the incident escalated once the data leak confirmed the severity, prompting a revised SEC disclosure. This highlights the increasing targeting of smaller, critical firms in supply chains by ransomware groups and the potential financial and reputational impacts on companies like Trio-Tech.
