About urlscan.io

A sandbox for the web

urlscan.io is a service to scan and analyse websites. When a URL is submitted to urlscan.io, an automated process will browse to the URL like a regular user and record the activity that this page navigation creates. This includes the domains and IPs contacted, the resources (JavaScript, CSS, etc) requested from those domains, as well as additional information about the page itself. urlscan.io will take a screenshot of the page, record the DOM content, JavaScript global variables, cookies created by the page, and a myriad of other observations.

Finally, urlscan.io will try to make a verdict whether the scanned website is considered malicious or suspicious. If the site is targeting the users one of the almost 400 brands tracked by urlscan.io, this will be shown in the scan results.

Q: What is difference between public and private scans?
A: Private scans can only be viewed if you know their full URL. They don't appear in search results and aggregations. We don't share private scan information with third parties, ever.

Q: How can I request the content of a scan to be removed from your website?
A: Please use the orange Report button on the result page of the scan.

Q: Can you prevent my domain from being scanned?
A: Yes, please send us a email at [email protected] with the domains you want to be blacklisted.

Q: Does urlscan.io show whether a website contains malware or phishing attempts?
A: Yes, we have some basic mechanisms for determining whether a website contains malicious content. Our proprietary phishing detection mechanism tracks 400 popular brands and can identify phishing or impersonation attempts of these brands.
We do record file downloads, but we do not detect whether a downloaded file is malicious, e.g. a malicious executable.

Q: Does urlscan.io detect when a malicious site is no longer active, e.g. cleaned up?
A: No, our website scans only provide point-in-time snapshots of the website content, we do not re-crawl existing scans.

Q: Can I use the "malicious" verdicts on urlscan.io as a blocking feed?
A: We don't recommend it as the occasional false positive verdicts still occur.

Q: Can I search urlscan.io for pages which have been detected as malicious?
A: This feature is available as part of the commercial urlscan Pro subscription and not available through the community search.

Q: Do you use my browser or Internet connection to analyze a website?
A: No! urlscan.io will browse any website you request itself, your browser is not involved. The website you want to scan will never learn your IP address and you will not be at risk when looking at the results.

Q: How does urlscan.io work?
A: We use the Google Chrome browser in Headless Mode to browse to the URLs submitted by users. We record the interaction of the page with the Internet and after the page has finished loading, we annotate the results with additional data sources.

Q: Do you store results indefinitely?
A: Yes, but right now we're not making a guarantee that the results of a scan will stay up for any period of time. When we hit certain limits we will have to start purging old scans.

Q: Do you support other browsers besides Google Chrome?
A: No, but you can set a custom User Agent during submission.

Q: Do you support IPv6?
A: Yes, and we're very happy about that because many similar services do not support it.
If you want to try a cool site, submit http://test-ipv6.com.

Q: Do private submissions deliver different results than public ones?
A: No, private submissions will deliver the same results as public ones. The only difference is that private submissions will not show up in the list of recently scanned sites and in the search results.

Q: Do you offer different browser locations/countries?
A: Not right now, we might include this feature in the future.

Q: Between different runs, websites often have a different number of HTTP transactions. Why is that?
A: The number of HTTP transactions depends on many factors:

  • Time of day and actual content of the site
  • Speed of the site (as we do have timeouts)
  • Advertising embedded in the site
Especially sites which employ a large amount of third-party ads and tracking will yield different results on each run. News website are the best example, as they often rely on ad revenue and have to deliver multiple ads from different sources.
