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 bausubstanz.com and not a lookalike like b-ausubstanz.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.
- OpenDiscuss this site on the forum
