Discarded industrial equipment can retain sensitive data
Retired industrial equipment can still hold recoverable data after files are deleted or storage is formatted.
The warning concerns old machines, control systems and specialist instruments used by businesses and organisations in China.
These devices can store production details, system settings, business records and precise location data from past work.
Reselling equipment without securely destroying its data can expose sensitive information to competitors or people seeking to misuse it.
Data linked to energy, transport and other key infrastructure could reveal how systems operate and where their weaknesses lie.
The risks extend from business losses to infrastructure and national security, especially when equipment containing sensitive geographic information is involved.
Organisations are advised to destroy data before equipment changes hands and to use qualified disposal services rather than casual resale.
People who suspect targeted collection of sensitive equipment can report it through China's national security reporting channels, including hotline 12339.
Discarded industrial equipment and specialist instruments can retain sensitive data even after files are deleted or storage is formatted, China News Service reports.
Residual data may include production parameters, control logic, customer records, financial reports, precise coordinates and system security information.
If equipment enters second-hand markets without proper handling, recovered data could expose commercial secrets or create risks for critical infrastructure and national security.
The article recommends professionally destroying storage media before transfer and using qualified recovery or destruction channels.

A retired device sheds its production function, but not its data risks.
National security is everyone’s responsibility, and everyone can contribute.
