cran.rstudio.com Overview

Description of cran.rstudio.com

cran.rstudio.com appears to be a mirror endpoint for the Comprehensive R Archive Network (CRAN), the primary distribution network for the R programming language and its contributed packages. The page shown offers downloads for R on Windows, macOS, and Linux, along with source code, manuals, FAQs, package listings, and links related to the broader R ecosystem.

Based on the domain structure and page content, this subdomain is associated with RStudio's infrastructure for accessing CRAN resources, while the underlying content serves the R community and the R Foundation ecosystem. Its purpose appears to be software distribution, package hosting, and documentation access for developers, researchers, students, and data analysts who use R for statistical computing and graphics.

Safety Assessment for cran.rstudio.com

The available scan data is broadly reassuring. No security engines flagged the domain at the time of this scan, and the site was not listed by the checked blacklist and threat-database sources. The domain is also long-established, which generally reduces the likelihood of opportunistic abuse compared with newly registered domains.

One malware scan reported a generic "suspicious" result tied to a mirrors page and several external CRAN mirror links. However, these detections appear to be low-confidence heuristic findings rather than corroborated malware identifications, and they are not supported by the broader engine consensus or blacklist checks. The screenshot and page content also match a legitimate software archive and download portal rather than a phishing page, scam storefront, or impersonation site.

Based on available data, no threats were detected at the time of this scan.

Technical Description

The site presents a valid SSL/TLS certificate issued through Amazon infrastructure, with certificate validity extending to 2026-11-14. It is served via AWS CloudFront and reports an Apache/2.4.66 (Unix) web server, with the observed edge location in Paris, France. The domain itself is mature, created in 1998, and uses Amazon Registrar nameservers.

DNSSEC appears to be unsigned, which is not uncommon but means DNS responses do not benefit from DNSSEC validation. Aside from that, the technical posture appears routine for a large content-distribution setup. No major infrastructure-level security concerns were evident from the provided scan details.
