Malicious Link Detection

Keeping Your Links Safe

We automatically scan every link you try to create and shorten with utm.rocks shortener to protect you and your audience from security threats. This article explains how our detection system works and what to do if your link is flagged.


How We Protect Your Links

When We Scan

Your links are checked at multiple points:

  • Before saving – When you create, edit, or duplicate a link
  • Daily rescans – Every day for a set period of time after the link is created or edited
  • Following redirects – We scan the final destination, not just the first hop

What We Check For

Using Google Web Risk technology, we detect:

  • Phishing sites – Fake pages designed to steal credentials
  • Malware – Sites that distribute viruses or harmful software
  • Deceptive content – Fraudulent or misleading websites

How Deep We Look

  • We follow up to 3 redirects to find the true destination
  • Links with more than 3 redirects are automatically blocked
  • We scan the final URL, not just your short link

When a Link Gets Flagged

🚫 Blocked Before Creation

If we detect a threat while you're creating, editing, or duplicating a link:

  1. You'll see a blocked modal
  1. The link won't be saved – We block it before it gets saved
  1. You can try again – Fix the destination URL and recreate the link

⚠️ Flagged After Creation

Sometimes a safe link becomes dangerous later. If our daily scans detect a new threat:

What you'll see:

  • A warning icon (⚠️) next to the link in your dashboard, and the link color will turn red
  • You will not be able to click, edit, delete, duplicate, copy the link, or download the QR Code

Troubleshooting Flagged Links

Step 1: Investigate the Destination

Check where your link actually goes:

  1. Manually visit the destination URL
  1. Follow any redirects to see the final page
  1. Look for anything suspicious: unexpected pop-ups, download prompts, or unfamiliar content

Common causes:

  • The destination site was hacked or compromised
  • A redirect in your chain points to a malicious site
  • The page content changed after you created the link

Step 2: Fix or Replace

If you control the destination:

  • Remove any malicious content or suspicious scripts
  • Check if your site was compromised
  • Eliminate any unwanted redirects
  • Update your security measures

If you don't control the destination:

  • Contact the site owner to alert them
  • Find an alternative, secure URL
  • Use a different source for your campaign

Step 3: Create a New Link

Once the issue is resolved:

  1. Verify the destination is clean and working
  1. Create a new shortened link
  1. Test it to confirm it works properly

False Positives: What If Your Link Is Safe?

We understand that security tools can occasionally flag legitimate content by mistake.

If You Believe Your Link Was Incorrectly Flagged

Contact our support team and include:

  • The destination URL where it should redirect
  • Why you believe it's safe – Explain the legitimate business purpose
  • Any context – Is this your own site? A well-known brand? Educational content?

What happens next:

  1. Our team will manually review your link within 3-4 business days
  1. If it's a false positive, we'll unblock it and email you
  1. If the security concern is valid, we'll explain why and suggest alternatives

Frequently Asked Questions

Why does UTM.io scan links? Other shorteners don't.

We're committed to keeping our platform safe for everyone. Link shorteners are sometimes abused for phishing and malware, and we take proactive steps to prevent that.

Can I disable scanning for my links?

Security scanning protects both you and your audience. However, Enterprise accounts have different scanning policies. Contact sales if you have specific requirements.

How long does the review process take?

Manual reviews typically take 1-2 business days. We'll email you as soon as we've made a decision.

Will my link be automatically unblocked if the destination is fixed?

No. Our daily scans will continue, but once flagged, a link requires manual review before it's unblocked.
