Problem
An attacker uses a shortened URL in a sponsorship message, hiding the actual phishing destination from the creator.
Solution
Root Cause / Diagnostic:
URL shortening services (e.g., bit.ly, tinyurl, or custom redirects) obscure the destination hostname and bypass automated corporate email security filters. Creators click what appears to be a media kit or product brief link, which redirects through multiple hops to a sophisticated credential-harvesting portal or zero-day browser exploit page.
Actionable Fix:
1. URL Expansion & Sandbox Inspection: Enforce the use of URL expansion tools (e.g., `checkshorturl.com` or `curl -I`) and automated sandbox previewing before opening shortened links in incoming sponsorship emails.
2. Organizational Link-Clicking Policy: Require sponsors to provide fully qualified, transparent corporate domain URLs for all contracts, briefs, and brand assets; reject shortened redirect links.
3. Safe Browsing Enforcement: Enable Google Chrome "Enhanced Safe Browsing" mode across all production machines to detect and block malicious redirection chains in real time.
Pro Tip:
Legitimate brands don't send important sponsorship contracts through bit.ly or tinyurl links; expand shortened links using a URL checker or tell the sponsor to email links from their corporate domain.
