Diagnose Website Phishing Warning

My site is suddenly being flagged with a phishing warning and visitors see a “risky site” message. I haven’t touched the code or added new pages in quite some time, so I need a fresh set of expert eyes to uncover what’s triggering the alert and to get the flag removed.

Small task, couple of hours research by someone with the right skills.

Current situation
• Phishing warning appears on major browsers and link-sharing platforms.
• No recent content or code updates on my end.
• The site does rely on a few third-party plugins/integrations that could be a vector.

What I’m after
I want a concise security assessment that pinpoints the root cause—whether it’s injected scripts, compromised plugin files, mixed-content issues, or something sitting on the server itself—and a clean fix that will clear the warning with Google Safe Browsing and similar services.

Deliverables
1. Brief report outlining the vulnerability or misconfiguration you find.
2. Steps you take to remediate it (e.g., file cleanup, plugin patch, DNS tweak).
3. Confirmation that the phishing warning no longer appears once caches propagate.

I will give url to candidates at the interview stage.
