ADDCN says misconfigured test source code briefly exposed some members’ names, national IDs and emails

Listed company ADDCN (5287) said on 26 May 2026 that during internal campaign-page development and testing on 25 May, misconfigured source-code handling briefly pushed some non-de-identified test source to an external platform, including names, national ID numbers and email addresses of members in a specific project ^[1]. The company said its security team found the issue the same day and completed a full takedown, deletion and block by 14:00, then cleared history, checked for external access, rotated keys and scanned the site, and assessed no material operational impact; it also said the data fields were independent and not linked, and that payment data, bank accounts, credit-card data or full resumes were not involved ^[1]. ADDCN said it has notified the personal-data authority as required and will email affected individuals and provide a dedicated customer-service contact; those affected should rely on that official notice and help line ^[1].
