North Korea's Smartphone Surveillance and Information War

North Korea is using specially modified smartphones to control what its citizens see and do.

These phones automatically censor South Korean words and take screenshots to monitor users.

While the government uses this technology to control information, some people are fighting back by hacking the phones to access banned content.

The phones themselves are also a business, violating international rules and making money for the government.

This shows how technology can be used by governments to control their citizens, and how some people are trying to resist.
