Description of codeforces.com
Codeforces appears to be a long-running competitive programming platform focused on coding contests, problem solving, rankings, and community participation. The homepage screenshot shows contest announcements, user ratings, contributor tables, and navigation items such as Contests, Problemset, Groups, Rating, EDU, and API, which suggests a service aimed at programmers, students, and algorithm enthusiasts.
Based on the domain name, visible content, and web-categorization data, the site appears to operate in the technology and education space. It functions as a hub for programming competitions and learning resources rather than as a commercial storefront. The platform is widely established online, with a strong traffic ranking and a domain registration history dating back many years, which is generally consistent with a mature community website.
Safety Assessment for codeforces.com
Scan results are largely reassuring at this point in time. Only 1 out of 91 security engines flagged the domain, while the malware scan reported no flagged files and blacklist checks did not indicate listings in major threat databases at the time of this scan. The screenshot also shows a normal-looking programming community website with contest posts and user statistics, rather than common signs associated with phishing pages, fake giveaways, or malware delivery.
One classification source labeled the site with elevated exposure and one security engine marked it as suspicious, so a small amount of caution is still appropriate. However, those signals appear limited and are not strongly corroborated by the broader scan data. The domain is also well established at 17 years old and has a meaningful traffic presence, which can modestly reduce concern when viewed alongside otherwise clean results.
Based on available scan data, no significant threats were detected at the time of this scan.
Technical Description
The site is served through Cloudflare infrastructure and resolves to an IP address hosted by Cloudflare in Toronto, Canada. It uses a valid SSL/TLS certificate issued by Google Trust Services, with validity extending to 2026-09-29, which indicates that encrypted HTTPS connections are supported. The visible challenge-platform URL in the scanned links suggests the site may use anti-bot or traffic-filtering mechanisms as part of its edge protection setup.
DNSSEC appears to be unsigned, which is not uncommon but means DNS responses do not benefit from that additional layer of authenticity protection. No major technical security issues were evident from the provided scan data beyond that relatively minor observation.
