Undetectable 2.51.0 Update: Chromium 153 and Advanced Protection Against Detection

The Undetectable team has prepared a fresh release. In version 2.51.0, we focused on the stealth of your digital fingerprints. We updated the core components and refined the spoofing mechanisms so anti-fraud systems have nothing to flag. Let’s break down all the changes in this article.

Chromium 153

We updated the browser core to the latest version of Chromium 153. Using an outdated engine can lead to a drop in your accounts’ trust. Platform protection algorithms instantly notice when your browser version lags behind what most real users are using.

A fresh core ensures that your sessions generate the correct network noise and blend in completely with the flow of regular users. In addition, it provides proper support for new web standards.

Improved Masking

We improved several masking algorithms, closing a number of non-obvious vulnerabilities at once.

Correct Locales for English

The browser now uses full regional locales en-US and en-GB instead of the generic en value. For real users, the language is always tied to a specific OS region. This is a small but important detail that strict anti-fraud filters often pay attention to.

Control Over DPR Spoofing

The Window Size settings now include an option to disable DPR (devicePixelRatio) spoofing. Previously, spoofing changed the system value itself, while the page was still rendered at the real scale. Because of this, some sites encountered discrepancies during checks, which reduced the profile’s trust.

Now you have a choice for protection against detection. If the DPR in the config differs from the system value, you can either adjust the scale in the window using “Ctrl + mouse wheel” or simply disable spoofing. This will eliminate any technical discrepancies.

Widevine DRM Update

We also improved the operation of the Widevine DRM module in the browser. The protection algorithms of streaming and advertising platforms often check this component to assess the legitimacy of a device. This improvement reduces the chances of a profile being detected even by the most advanced checkers.

What We Fixed

We also worked on interface stability. In version 2.51.0, the Start page behavior has been fixed. The start page now loads according to your settings.

In Conclusion

Undetectable 2.51.0 delivers the most up-to-date core and more controllable masking. The fresh Chromium 153 provides a baseline level of trust, while targeted DPR settings and new locales close vulnerabilities against sophisticated anti-fraud algorithms. We continue to develop a tool that takes care of all the technical routine for you. Update to the latest version and scale your projects!
