Understanding How Mirror Sites Work
https://onionlinks.live/blog/d....arknet-desires-revie
A mirror is simply a copy of a website hosted on a different address. Legitimate services often use them to balance heavy traffic or provide backups if one entry point is under a DDoS attack. Bad actors create "evil twins" of these mirrors - these fake sites act as a middleman, passing your login details to the real site while keeping a copy for themselves.
You should understand that these clones are often automated. They use scripts to pull live data from the real site - the prices, listings and even the "users online" counts look real. Because the content is mirrored in real time, the only way to tell the difference is often the onion address itself or a specific verification key provided by the developers.
