activetk.jp Overview

Description of activetk.jp

ActiveTK.jp appears to be a Japanese technology website offering free web-based utilities and small online tools. The page title and description indicate a focus on making everyday tasks more convenient, and the homepage presents the service as a collection of easy-to-use web tools that are described as open source.

Based on the domain name, metadata, and third-party categorization, the site appears to fit within the technology or software-tools space rather than commerce or media. The navigation links suggest sections for service information, terms, privacy, notes, developer information, and contact details, which is consistent with a small independent web-tools platform operated under the ActiveTK name.

Safety Assessment for activetk.jp

Scan results were broadly favorable at the time of this scan. The domain was not flagged by any of 91 security engines, and the checked malware and phishing blacklist databases did not report active listings. The domain is also several years old and has measurable traffic presence, which can be mildly reassuring in context.

There were, however, some limited caution signals from a heuristic malware scan. One scanned page was marked as suspicious, and several referenced domains or subdomains were labeled with generic heuristic names rather than a confirmed malware family. Those kinds of generic detections can sometimes reflect pattern-based matches, research-related content, or false positives rather than verified malicious activity. The homepage also references an onion mirror and includes some security- or research-themed subdomains, which may contribute to heuristic alerts even when broader engine consensus remains clean.

Taking the full picture into account, the stronger signals are the zero out of 91 engine detections and clean blacklist checks, while the adverse findings appear lower-confidence and uncorroborated. Based on available data, no significant threats were detected at the time of this scan.

Technical Description

The site uses a valid Let's Encrypt SSL certificate with expiry in October 2026, and it is served over an nginx web server from an IP located in Japan. DNS points to Cloudflare nameservers, while the reported hosting infrastructure is associated with BETINC. The domain has been registered since March 2022 and is set to expire in March 2027.

From a security-configuration perspective, DNSSEC appears to be unsigned, which is not uncommon but means DNS responses do not benefit from DNSSEC validation. No blacklist-database issues were reported in the provided checks, and no iframe usage was noted in the scan summary.
