Is aumentoja83.s3.us-east-005.backblazeb2.com legit or a scam?
Phishing subdomain on Backblaze B2 storage; G-Data and Gridinsoft detect it as phishing; part of a known malicious bucket prefix used for credential theft.
These checks passed — but they don't clear the site. A clean antivirus result, valid SSL, and a calm server only mean it isn't hosting malware; they say nothing about whether the business is real. This verdict is based on the site's conduct and content, not a malware detection.

MT Intelligence
The domain is a subdomain of the legitimate Backblaze B2 object-storage service, but the specific bucket (aumentoja83.s3.us-east-005.backblazeb2.com) is being used to host phishing content. G-Data and Gridinsoft both classify it as phishing. Our research found multiple related subdomains on the identical bucket prefix—aumentoja21, aprovacoestododia, beneficioexclusivo—all flagged as phishing by security vendors and sandboxes. The shared s3.us-east-005.backblazeb2.com hostname is classified as a malware distributor with a 1/100 trust score. Although the parent domain (backblazeb2.com) is 3625 days old and legitimate, individual bucket subdomains like this one are created on-demand for short-lived phishing campaigns. The pattern—disposable B2 buckets used for credential harvesting—is well-documented in phishing infrastructure research.
