Is it safe to use the wifi inside the hotel? Do you steal personal information?

Unsafe, may steal personal information. Public ***WIFI is insecure because it collects your information when you use it. The Mac address, these hardware information and your Zhihu ID (or others) are monitored.

Or it just hijacked your network to do something ulterior (for example, you visited Baidu, jumped to hao 123 and then jumped back to Baidu, shamelessly jumping to other homepages without returning). Without this network environment, you can't continue to hijack you (unless your device is recruited).
