Although most Apple users install updates immediately, there is always an exception. If you are one of those who do not update the Appliances them, you should know that the letter “d” is not always the letter “d” when it appears in the Safari address bar.
It may not sound serious to you, but it is a very important problem because it can lead you to adventures according to various researchers security.
IDN homogeneity attacks can occur if you write a domain name with Unicode characters that resemble typical Latin letters, but they are not.
These domains are used for phishing, and they deceive users to think they have access to a regular site instead of a cleverly created clone.
Xisigr, a security researcher at Tencent Security Xuanwu Lab, recently discovered how they manage Apple's Unicode characters.
This, which he found the researcher is that Apple has done a good job with most Unicode characters, except one that is letter letter (ꝱ) (U + A771).
The character looks like a regular letter 'd', except it also features a lower apostrophe. So xisigr discovered that Safari was not showing the apostrophe, but was showing the letter dum as the Latin letter d.
The researcher reported his findings to Apple, which released security updates in July for its Safari app, and software for iOS, macOS, tvOS and WATCH.
