What to do

No action needed. Stay alert as usual — a clean result reflects this scan only, and sites can change after they are checked.

A clean result means no known threat signals were found in this scan — it is not an absolute guarantee, and a site can change after it is checked.

Findings

Strongest first
InfoCross-domain scripts injected at runtime
16 script(s)

The page dynamically injected scripts from other domains. This is extremely common on legitimate sites (CDNs, analytics, asset domains) and is shown for context only.

Analyst noteNoisy by itself — a CDN/asset domain (e.g. a brand's own *.githubassets.com) is normal. Only meaningful if the source domain is unrelated/suspicious.
