Description of sin1.contabostorage.com
sin1.contabostorage.com appears to be a subdomain hosted under contabostorage.com, which suggests it may be part of a cloud storage or object storage infrastructure operated through Contabo-related hosting services. The "sin1" label likely refers to a Singapore region or endpoint, and the domain structure is consistent with storage buckets, hosted assets, or region-specific delivery endpoints rather than a standalone consumer-facing website.
Based on the available categorization data, the domain has been associated by multiple web-classification providers with information technology or hosting-related use. At the same time, some classification sources also associate it with malicious or phishing-related activity, which may indicate that this storage endpoint has been used to host abusive content, temporary phishing pages, or files delivered through shared infrastructure. Because this is a storage-style subdomain rather than a branded business homepage, its purpose may depend heavily on the specific content served at a given time.
Safety Assessment for sin1.contabostorage.com
This domain shows several risk indicators at the time of this scan. It was flagged by 12 out of 90 security engines, with multiple detections describing phishing or malicious activity. In addition, one major phishing database listing and another generic malicious-object listing were present, even though other content-malice databases were clean. These findings suggest that the subdomain may have been involved in deceptive or abusive activity, or may have hosted content that triggered phishing-related detections.
Other signals are more neutral. The malware scan reported no flagged files in the sampled content, there were no external links or iframes detected in that scan, and the domain itself is not newly registered. However, the absence of detected malicious files in a limited scan does not outweigh the broader multi-engine phishing consensus. Because this appears to be a hosted storage endpoint on shared infrastructure, risk can also vary depending on the specific object or page being accessed.
Following a manual review by the PCRisk team, the published trust score has been adjusted to reflect additional context. Based on these findings, this website may pose potential risks to visitors.
Technical Description
The domain uses a valid SSL/TLS certificate issued by ZeroSSL, with expiry extending to 2026-11-22. DNSSEC appears to be unsigned, which is common but means DNS responses do not benefit from DNSSEC validation. The nameservers are provided through Cloudflare, while the resolved server IP is hosted by Contabo Asia Private Limited in Singapore.
From an infrastructure perspective, this appears to be a cloud-hosted storage or delivery endpoint rather than a traditional website running on an identifiable web server stack. No DNS-based mail-reputation blocklist hits were reported in this scan. The main technical concern is not the certificate or hosting setup itself, but the reputation signals indicating that content served from this endpoint may have been associated with phishing-related activity at the time of review.
