OKX-dolphin-crawler is a bot in the security scanners category, operated by OKX.
OKX Dolphin Crawler simulates visits to target web pages as part of malicious dApp scanning
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.
OKX-dolphin-crawler identifies itself with this user agent string:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/110.0.0.0 Safari/537.36 OKX-dolphin-crawlerAnyone 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.
We have not confirmed whether OKX-dolphin-crawler 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.

We have not confirmed whether OKX-dolphin-crawler 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.
Add "User-agent: OKX-dolphin-crawler" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "OKX-dolphin-crawler" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so OKX-dolphin-crawler may not follow it, and anyone can send OKX-dolphin-crawler's user agent, so a fake OKX-dolphin-crawler ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
