We’re shipping look-alike SSID detection.
A network name spelled with a Cyrillic letter — or an invisible character — can render identical to yours. Now the app reads the bytes, not the pixels.
Our fourth detector goes after the lure itself: homoglyph SSID detection. It catches network names spelled with confusable or invisible Unicode characters — the ones that render pixel-identical to a name you trust — on Windows, free.
Same pixels, different bytes. The eye sees one network; the computer sees two.
A lure that passes a human glance
A homoglyph SSID is a network whose name looks identical to one you trust but is spelled with different characters — a Cyrillic “а” for a Latin “a,” for instance. Paired with an evil-twin access point, it’s a powerful lure: the name passes a glance, and a distracted user connects.
Cyrillic а
Characters that render as nothing
The subtlest version uses invisible characters — a zero-width space spliced into a trusted name renders as nothing, so the SSID looks byte-for-byte identical while being a different string underneath. No human eye, and most software, would ever catch it.
Canonical comparison, not pixels
The detector reduces every nearby network name to a canonical comparison key: it drops invisible and zero-width characters, normalizes the text, strips combining marks, maps every Unicode digit to ASCII, and applies a curated confusables table. When two networks produce the same key but have different raw characters, that’s a look-alike — flagged as a medium-severity alert. It deliberately does not case-fold, because SSIDs are case-sensitive and a capitalization difference isn’t an attack.
Detection is free
Look-alike SSID detection ships in the free version and always will. Being warned that an impostor of your network is broadcasting nearby — before you tap connect — is exactly the kind of awareness that shouldn’t be paywalled.
