About Cron-jobOrg

Scheduled execution of your websites and scripts.

Webhook senders call your endpoints to deliver events from payment, messaging and SaaS platforms. Blocking them breaks integrations. Allow them on the webhook paths they need and nowhere else.

Cron-jobOrg user agent

Cron-jobOrg identifies itself with this user agent string:

  • http://cron-job.org/

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 Cron-jobOrg in robots.txt

We have not confirmed whether Cron-jobOrg 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.

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: Cron-jobOrg group, Cron-jobOrg ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take Cron-jobOrg from Cron-jobOrg's user agent; check cron-job.org'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. Cron-jobOrg may not follow the rule. robots.txt is a request that nothing enforces, and we have not confirmed that Cron-jobOrg 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 Cron-jobOrg's user agent, and a scraper using it is not bound by cron-job.org's robots.txt policy. Only checking the source network tells a real Cron-jobOrg from a fake one.

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

Does Cron-jobOrg respect robots.txt?

We have not confirmed whether Cron-jobOrg 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 Cron-jobOrg?

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

Is robots.txt enough to block Cron-jobOrg?

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