MT Intelligence
StumbleUpon was a well-established web service that operated for 17 years before its official shutdown on June 30, 2018. The domain is now maintained as a landing page promoting Mix, the successor platform built by the same founders. Our antivirus network flagged zero malicious detections across 92 engines, SSL is valid and current, and the hosting IP has zero abuse reports. The page displays standard OAuth login modals and app-download prompts consistent with legitimate content-discovery services. While the evidence package includes one user report of a hijack scam reached via an ad (not the site itself), this appears to be ad-related rather than an attack originating from the domain. The domain's 8,986-day age and Delaware corporate registration confirm its legitimate history.

Still, stay alert
No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.
- Double-check the exact URL in your address bar
Confirm you are actually on stumbleupon.com and not a lookalike like s-tumbleupon.com.com or an IDN homoglyph.
- Use a password manager
Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.
