About GenomeCrawlerd

GenomeCrawlerd is the crawler of Nokia Deepfield Genome, which maps internet services and content for network operators.

Security scanners probe sites for vulnerabilities, certificates and exposed services. Some are research projects, some are vendors you hired. Allow your own scanners and block the rest at the WAF.

GenomeCrawlerd user agent

GenomeCrawlerd identifies itself with this user agent string:

  • Mozilla/5.0 (compatible; GenomeCrawlerd/1.0; +https://www.nokia.com/genomecrawler)

Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.

How to block GenomeCrawlerd in robots.txt

We have not confirmed whether GenomeCrawlerd follows robots.txt. Add a rule, then check your logs to see that it stopped. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.

Block GenomeCrawlerd from the whole site

User-agent: GenomeCrawlerd
Disallow: /

Block GenomeCrawlerd from some folders

User-agent: GenomeCrawlerd
Disallow: /private/
Disallow: /search

Allow GenomeCrawlerd only on some folders

User-agent: GenomeCrawlerd
Allow: /blog/
Disallow: /

Allow GenomeCrawlerd and block other crawlers

User-agent: GenomeCrawlerd
Allow: /

User-agent: *
Disallow: /

Things to know

  • Each host needs its own file. Rules on www.example.com do not apply to shop.example.com.
  • A crawler obeys only the most specific group that names it. Once you add a User-agent: GenomeCrawlerd group, GenomeCrawlerd ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take GenomeCrawlerd from GenomeCrawlerd's user agent; check Nokia's own documentation if it publishes a different robots.txt name.
  • Crawlers cache robots.txt, so changes can take up to a day to apply. Disallow stops crawling but does not remove pages already collected or indexed.

Limits of robots.txt

  1. GenomeCrawlerd may not follow the rule. robots.txt is a request that nothing enforces, and we have not confirmed that GenomeCrawlerd follows it. Check your logs after adding a rule.
  2. The user agent could be fake. robots.txt matches the name a request claims. Anyone can send GenomeCrawlerd's user agent, and a scraper using it is not bound by Nokia's robots.txt policy. Only checking the source network tells a real GenomeCrawlerd from a fake one.

Treat robots.txt as a statement of your policy, and enforce it where requests arrive.

Who should care about GenomeCrawlerd

Publishers

Allow GenomeCrawlerd if it is a service you use, and keep its visits out of page views and ad requests either way.

Media buyers and advertisers

GenomeCrawlerd is not a person. Exclude it from campaign and conversion data so reports reflect real visitors.

Transfon Security for advertisers

E-commerce

Allow GenomeCrawlerd only if it works for your store, and keep it away from cart and checkout.

SaaS and APIs

If GenomeCrawlerd is a service you use, allow it on the endpoints it needs and block it elsewhere.

Block GenomeCrawlerd with Transfon Security

robots.txt is a request, not an enforcement. Transfon Security shows GenomeCrawlerd by name in the Top Bots report, so you can see how often it visits and which pages it reads. Block or allow it with a User Agent rule, or slow it down with a rate limit decision rule.

Transfon Security

Control GenomeCrawlerd on your site

  • See every GenomeCrawlerd visit and the pages it reads
  • Spot bots that fake trusted crawler names
  • Block, allow or rate limit GenomeCrawlerd with one rule
  • Works with or without robots.txt support

Frequently asked questions

What is GenomeCrawlerd?

GenomeCrawlerd is a bot in the security scanners category, operated by Nokia. GenomeCrawlerd is the crawler of Nokia Deepfield Genome, which maps internet services and content for network operators.

Does GenomeCrawlerd respect robots.txt?

We have not confirmed whether GenomeCrawlerd follows robots.txt. Add a robots.txt rule, then check your logs to see that it stopped, and block it by user agent if it did not.

How do I block GenomeCrawlerd?

Add "User-agent: GenomeCrawlerd" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "GenomeCrawlerd" at your WAF. In Transfon Security that is one User Agent block rule.

Is robots.txt enough to block GenomeCrawlerd?

No. robots.txt is voluntary, so GenomeCrawlerd may not follow it, and anyone can send GenomeCrawlerd's user agent, so a fake GenomeCrawlerd ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.

Should I block GenomeCrawlerd?

Security scanners probe sites for vulnerabilities, certificates and exposed services. Some are research projects, some are vendors you hired. Allow your own scanners and block the rest at the WAF.
