Description of qrsu.io
qrsu.io appears to be a web-based QR code generator and URL shortener. Based on the page title, meta description, and visible homepage content, the site offers users a way to paste a link, generate a QR code, and create a shortened URL for sharing. The interface is minimal and presents itself as a free utility with no registration required.
The site appears to be hosted as a lightweight web application rather than a large consumer platform. Its branding is limited to the qrsu.io name, and the available content suggests it is operated by an unidentified party rather than a clearly disclosed company or organization. The presence of privacy-policy and terms-of-service pages indicates an attempt to present standard service documentation, although the homepage itself provides limited operator transparency.
Functionally, services like this can be used for legitimate link sharing, marketing, and convenience. However, URL shorteners can also obscure destination addresses, which may increase abuse potential if the operator does not enforce strong moderation or destination screening.
Safety Assessment for qrsu.io
Multiple security signals raise concern about this domain at the time of this scan. It was flagged by 17 out of 91 security engines, and several web-classification sources categorized it as phishing or fraud-related. In addition, some blacklist and threat-database checks indicated listings associated with suspicious or phishing-related activity, even though other checks were clean. This mixed but notably negative pattern is stronger than a single low-confidence heuristic and suggests the domain may have been associated with abusive behavior.
The site presents itself as a QR code and URL shortening service, which is a category that can be attractive for misuse because shortened links may conceal the final destination from visitors. While the page design looks simple and functional, the combination of multi-engine phishing detections, phishing-oriented categorization, and threat-database listings materially increases risk. The malware scan did not report flagged files, but its generic object labeling and the broader reputation data do not offset the larger number of phishing-related detections.
Based on these findings, this website may pose potential risks to visitors at the time of this scan, particularly if used to create or follow shortened links without independently verifying the destination.
Technical Description
The domain uses a valid Let's Encrypt SSL certificate with an expiry in September 2026, which indicates encrypted HTTPS connectivity was available at the time of testing. It appears to be hosted on Vercel infrastructure at IP address 76.76.21.21 in the United States, with GoDaddy-listed nameservers. The site appears to be built with a modern JavaScript framework, as suggested by the _next static asset paths.
From a security posture standpoint, DNSSEC is not enabled, and the domain is unsigned. No DNS-based mail-reputation blocklist hits were reported in the provided data. The main technical concern is not the TLS setup or hosting stack, but the reputation layer: numerous phishing-related detections and suspicious classifications associated with the domain outweigh the otherwise ordinary hosting configuration.
