cs204.github.io Overview

Description of cs204.github.io

This domain appears to be a GitHub Pages site hosting educational material related to computer science or informatics. The page title is in Russian ("Информатика"), and the visible navigation plus linked resources suggest a collection of notes, lessons, and technical examples covering topics such as programming, control systems, convolution, computer vision, and mathematics-related concepts.

Based on the domain structure, the site is likely operated by an individual, student, educator, or course maintainer using GitHub's static hosting platform rather than by a standalone commercial organization. The referenced resources include developer documentation, academic links, and embedded video content, which is consistent with a personal or instructional project site.

Safety Assessment for cs204.github.io

The available scan data is broadly reassuring. No detections were reported by the security engines referenced in the scan, and the domain was not listed by the major malware, phishing, or URL-blocking databases checked at the time of this scan. The domain is also relatively old, which can modestly reduce risk compared with newly created sites.

One automated malware scan did note a generic suspicious indicator tied to a referenced IP address rather than to flagged files on the site itself. In this case, no local files were flagged, no external links were flagged, and the finding appears to be a low-confidence heuristic associated with a referenced domain/IP rather than clear evidence of harmful site content. Based on available data, no threats were detected at the time of this scan.

Technical Description

The site is hosted on GitHub Pages infrastructure and resolves to an IP associated with GitHub, Inc. It presents a valid Let's Encrypt SSL certificate with expiry listed as 2026-12-29. The web server is identified as GitHub.com, which is consistent with a static site deployment on a mainstream hosting platform.

DNSSEC appears to be unsigned, which is common but means DNS responses do not benefit from DNSSEC validation. No blacklist hits were reported in the provided threat-database checks, and the main technical caution in the scan is the presence of a generic heuristic flag on one referenced IP address. Based on the provided data, there are no strong technical indicators of active malicious behavior on the site itself at the time of this scan.
