Description of clc.trkblue.com
The domain "clc.trkblue.com" appears to be a subdomain used within a URL-shortening or click-tracking service, based on its naming pattern ("clc" likely standing for "click" and "trkblue" suggesting "tracking" branding). Such subdomains are typically used to redirect visitors from marketing emails, advertisements, or affiliate links to other destination pages. The operator of the parent domain "trkblue.com" is not clearly identified in available registration data, which is common for link-tracking infrastructure providers.
At the time of this scan, the specific page loaded at this subdomain returned a "404 Not Found" error, indicating that the tracking link or redirect target is no longer active, has been removed, or was never properly configured. This suggests the subdomain may have previously been used to host or redirect to a specific campaign page that is no longer available.
Without additional context, it is difficult to determine the precise business purpose of the broader trkblue.com service, but click-tracking subdomains of this type are frequently leveraged in email marketing, SMS marketing, and sometimes in phishing or spam campaigns, since they can mask the true destination URL from the recipient.
Safety Assessment for clc.trkblue.com
This domain was flagged by 3 out of 91 security engines at the time of this scan, with designations including "malicious," "phishing," and "spam." Additionally, one classification provider listed the associated content as phishing-related, and another heuristic-based provider flagged it under a generic suspicious-object designation. These signals, while not overwhelming in volume, do span multiple independent categories of concern (malware/phishing classification and spam), which raises some caution.
The domain's IP address was also found listed on one DNS-based mail-reputation blocklist (SURBL). This type of listing primarily reflects email-sending reputation rather than confirmed malicious web content, and can sometimes result from shared hosting infrastructure rather than the site's own behavior - however, it is still noted here for completeness. Meanwhile, a widely used web-safety blacklist reported no issues, and the malware file scan of the single page found showed no flagged files.
Considering the combination of phishing/spam classifications from multiple distinct sources, the 404 error page currently being served, and the lack of ranked traffic data for this domain, this website may pose potential risks to visitors, particularly if it is being used to redirect users from unsolicited messages. Visitors who arrived at this link via an unexpected email or text message should exercise added caution.
Technical Description
The site uses a valid SSL/TLS certificate issued by Google Trust Services, currently set to expire in December 2026, and is served through Cloudflare's network infrastructure with an IP address located in Toronto, Canada. The domain itself was registered through NameSilo, LLC in December 2024, making it a little under two years old at the time of this scan, and DNSSEC is not enabled for this domain.
The web server is identified as nginx behind Cloudflare's proxy, and the page currently returns a generic "404 Not Found" response, suggesting the specific tracking link or resource requested is no longer valid or has been deactivated. No iframes, external links, or referenced domains were detected during the malware scan of the current page content.
