Link: .su domain link redirection from new sender domains

Catches inbound messages from recently established sending domains where a link in the body ultimately redirects through a .su (Soviet Union) top-level domain, despite the visible link pointing elsewhere. These messages often masquerade as academic transcript requests, invitations, or administrative notices, using legitimate-looking business or organizational senders to deliver links that funnel recipients through .su-based redirect infrastructure, a technique commonly used to obscure the final malicious destination.
