Description
This rule identifies suspicious URLs that exploit the username component in links with 'youtube.com'. Attackers use this technique to trick users into believing the link is legitimate while redirecting to a malicious domain. The rule detects:
Links where youtube.com is used as a username (e.g., [email protected]).
and where the root domain does not match youtube.com.
Excessive URL-encoded padding (%20) that obscures the malicious domain in previews, such as in email clients or chat applications.
