speccalc.web[.]app Overview

Description of speccalc.web[.]app

speccalc.web[.]app appears to be a small web-based calculator project hosted on a cloud app platform. The page title, "Scientific Calculator," and the meta description suggest it is presented as a calculator intended for students, with a visually styled interface rather than a business or transactional website.

Based on the screenshot and metadata, the site seems to function as a simple front-end utility page with custom JavaScript and CSS assets. It does not appear to represent a major brand, organization, or formal software vendor, and no clear operator identity is visible from the provided scan data.

The domain uses a hosted subdomain under web.app, which is commonly used for lightweight web applications, demos, and personal projects. Classification data also places it broadly in information technology or web hosting-related categories, which is consistent with a small hosted web tool.

Safety Assessment for speccalc.web[.]app

The scan results show mixed signals. On one hand, 3 out of 92 security engines flagged the domain, and the malware scan marked one page object as malicious using a generic detection label. Several local assets such as CSS and JavaScript files were also flagged by the same scan process, which may indicate suspicious scripting behavior, obfuscation, or simply a low-confidence heuristic match rather than confirmed malware.

On the other hand, major blacklist and threat-database checks were largely clean at the time of this scan, including broad browsing-protection and DNS-based checks. The domain is also relatively old at about 7 years, which can modestly reduce concern compared with newly created throwaway domains. However, the presence of multiple engine detections, a low trust score, and one blacklist-style listing mean the site should still be treated cautiously.

The page content itself appears minimal and somewhat unusual for a calculator, with a sparse interface and external references to development and hosting platforms. Based on these findings, this website may pose potential risks to visitors.

Technical Description

The site uses a valid SSL/TLS certificate issued by a mainstream certificate provider, and it is hosted on infrastructure associated with Google LLC at IP address 199.36.158.100. The domain is a web.app subdomain, which indicates deployment on a managed hosting platform rather than a standalone dedicated server. Nameservers also point to Google-managed DNS.

DNSSEC appears to be unsigned, which is not uncommon but does mean DNS responses do not benefit from that additional integrity layer. The scan also noted several flagged local script and stylesheet resources, plus a challenge-platform URL consistent with an anti-bot or access-control component. While these findings do not by themselves confirm malicious behavior, they do suggest that the site's client-side resources warranted scrutiny at the time of analysis.
