• Could a legitimate site like mirrors.tuna.tsinghua.edu.cn still be used in a scam?

Even trustworthy domains get spoofed in phishing emails (a fake message that only looks like it's from mirrors.tuna.tsinghua.edu.cn), and legitimate sites are occasionally compromised on specific pages.

  No — mirrors.tuna.tsinghua.edu.cn is not currently on the major browser blocklist feeds that Chrome, Safari, Firefox, and Edge rely on. Note that blocklists can lag behind brand-new scam domains, so "not listed" is reassuring but not a guarantee on its own.

• Where is mirrors.tuna.tsinghua.edu.cn hosted?
  mirrors.tuna.tsinghua.edu.cn resolves to an IP operated by China Education and Research Network in CN (University/College/School).
