Google Chrome's secret mode has not yet become "completely secret"

Internet.

Google Chrome secret mode is a function to maintain privacy on the Internet.The website will not know when the user has visited, and you may be lucky that you can go beyond the pay wall (you can browse content that can only be accessed by users who pay for the price).

However, web developers and publishers are becoming smarter, and there are sites that detect secret mode and warn them.Google recently released Chrome 76.It has been updated so that secret mode becomes more secret.

However, some sites have already been confirmed to avoid it.

Apde to make sure that it is secret mode

Before Chrome 76, the website was able to use a loop hole.In the secret mode, the "Filesystem API", which creates and reads files in a user local, was disabled.The website side recognized that the API call failed = browsing in secret mode, with a code that calls the Filesystem API.

This point has been revised in Chrome 76, and the FileSystem API is also effective in secret mode.In other words, websites could no longer determine what mode they were browsing in the previous way.

It looks like NYT is finding a way to avoid

However, as 9to5 Google pointed out, The New York Times (hereinafter NYT) has found a way to avoid this correction.If you visit NYT in secret mode and exceed the monthly free viewing article, a pop -up notification will be displayed that encourages you to log in and continue browsing.It is not clear whether NYT has found another loop hole, but 9to5 Google states that "NYT did not have a source code written as a CHROME 76 measure."

Maybe there is still a missing path ...

According to a security researcher, it may be possible to determine the secret mode by focusing on the capacity available in the FileSystem API.In secret mode, the storage that can be temporarily used in the FileSystem API is limited to 120MB.Another security researcher has discovered that tabs open in normal mode are slower than tabs open in secret mode.

In either case, of course, the correction on Chrome 76 is meaningless, even if NYT is doing it.The Chrome development team seems to have to start over again from the beginning ...
