Description of yifubafu.s3.ap-southeast-1.amazonaws.com
This domain is an Amazon S3-hosted subdomain under amazonaws.com, which suggests it is likely being used to serve files or web content from an object storage bucket rather than operating as a standalone branded website. The hostname structure indicates a bucket or project-specific name hosted in the Asia Pacific (Singapore) AWS region, and the web server infrastructure points to AmazonS3.
Because this is a cloud-storage subdomain rather than a conventional business domain, the apparent operator may be the AWS account holder controlling the S3 bucket, while the parent domain itself is operated by Amazon. Based on the available categorization data, this specific hosted resource appears to have been associated with malicious or phishing-related activity at the time of the scan.
Safety Assessment for yifubafu.s3.ap-southeast-1.amazonaws.com
Multiple security signals raise concern about this URL at the time of the scan. It was flagged by 16 out of 91 security engines, and several web-classification sources categorized it as malicious, phishing-related, or associated with malware activity. Although one malware scan did not detect flagged files in the limited content it checked, that clean result is outweighed by the broader multi-engine consensus around harmful behavior.
Blacklist and threat-database results were mixed rather than fully clean. Major content-malice checks shown here did not report a listing at the time of the scan, and the IP was not listed on the checked mail-reputation blocklists, but one blacklist provider associated with the scan data did list the URL with a generic malicious-object label. The very low published trust score and phishing designation also align with the broader detection pattern.
Based on these findings, this website may pose potential risks to visitors.
Technical Description
The host is served from Amazon S3 infrastructure in the ap-southeast-1 region (Singapore) and resolves to an AWS IP address. It presents a valid SSL certificate issued for Amazon infrastructure, with expiry shown as 2026-11-28. The web server identifies as AmazonS3, which is consistent with a storage-bucket endpoint rather than a traditional dedicated web application stack.
The parent domain amazonaws.com is long-established, but that age does not meaningfully validate this specific S3 subdomain because cloud-hosted subpaths and bucket endpoints can be created and repurposed independently. DNSSEC appears to be unsigned in the provided data. The main technical concern here is not TLS configuration, but the reputation-based evidence indicating that this hosted resource may have been used for phishing or malware-related delivery at the time of the scan.
