Two obscure letters reportedly make some fake URLs look genuine in Chromium

TECHNOLOGY & SOFTWARENEEDS REVIEWUpdated:

A report says researchers found that two uncommon letters—Cyrillic ө and Latin ƙ—can be used in lookalike web addresses that Chromium-based browsers display in Unicode rather than in their more revealing Punycode form. The letters reportedly resemble ordinary characters closely enough to help a fake address look like a familiar site.

Testing display and detection with twenty demonstration domains

According to the report, the researchers registered 20 demonstration domains and said the characters could evade Chromium’s Unicode-display and similar-domain checks. That is the odd mismatch: safeguards intended to expose suspicious internationalized addresses may reportedly show some impostor addresses in the friendlier-looking form instead.
