Homoglyph attacks: when 0 looks like o
By Trusterity · Updated 14 November 2026
kestre1bank.com and kestrelbank.com look identical at a glance. That's the whole attack.
Typical swaps
- o ↔ 0, l ↔ 1 ↔ i, e ↔ 3
- m ↔ rn, w ↔ vv
- Characters from other alphabets that look Latin (shown in browsers as “xn--” addresses)
How to spot them
- Don't trust what a link says — hover or long-press to see the real address.
- Type important addresses yourself or use bookmarks.
- Be suspicious of any “updated details” email, however familiar the sender looks.
