Description of facebook-com.gitbook.io
This URL appears to be a GitBook-hosted page published under the subdomain facebook-com.gitbook.io. GitBook is commonly used for documentation, knowledge bases, and lightweight web publishing, and the visible page layout matches a standard GitBook documentation template rather than a full standalone website. The page title and branding shown in the screenshot reference "Facebook.com," which suggests the content may be attempting to present itself as related to Facebook while actually being hosted on GitBook infrastructure.
Based on the screenshot, the page itself is minimal and largely empty, showing an "Initial page" heading, a search box, and standard GitBook interface elements. There is no clear evidence of a legitimate corporate Facebook property here, and the use of a third-party publishing subdomain with a brand-like name may indicate an unofficial page or a look-alike setup rather than an authorized Facebook-owned service.
Safety Assessment for facebook-com.gitbook.io
Multiple independent security signals raise concern about this URL at the time of this scan. It was flagged by 14 out of 91 security engines, and several web-classification providers categorized it as phishing or fraud-related. In addition, one phishing-focused threat database listed the domain, which is a stronger warning sign than a generic heuristic match. The domain name also closely resembles the Facebook brand while being hosted on a GitBook subdomain, which may indicate a look-alike page intended to benefit from user trust in that brand.
The malware scan did not report confirmed malicious files, but it did attach a generic suspicious label to the domain and several internal links. That kind of heuristic finding alone would be low confidence, but here it is accompanied by broader phishing-related detections from multiple sources. There is also a DNS-based mail-reputation blocklist listing on the IP, although that signal is weaker and does not by itself prove harmful website content.
Based on these findings, this website may pose potential risks to visitors.
Technical Description
The site is served over HTTPS with a valid TLS certificate issued by a mainstream certificate authority, and the observed hosting stack appears to rely on Cloudflare infrastructure. The resolved IP address is 104.18.40.47, the web server is reported as Cloudflare, and the nameservers are also on Cloudflare. This setup is common for both legitimate and abusive sites, so it should not be treated as a trust signal by itself.
The domain record indicates an older registration date, but because this is a GitBook subdomain, the age of the parent domain does not necessarily reflect the age or legitimacy of the specific hosted page. DNSSEC appears to be unsigned, which is not unusual but means DNS responses do not benefit from DNSSEC validation. No confirmed malicious files were identified in the page scan, though the broader reputation data and phishing classifications remain the primary technical concern.
