Doubts about the erro infos about creepjs HOT 9 CLOSED

Special thanks to adtechmadness for the article. I'm just a fan of the blog.

JS evasions cause glowing leaks in the native code. As outlined in the article, patching them is possible and that can cause more leaks. The use of a Proxy is a technique described. It has some less obvious leaks.

I see, thank you about your awnser, and why the value is changed this error appears : Navigator.deviceMemory:
failed undefined properties

from creepjs.

This should return undefined.

Object.getOwnPropertyDescriptor(navigator, 'deviceMemory')

If we do something like this, the above no longer returns undefined

Object.defineProperty(navigator, 'deviceMemory', { value: 4 })

from creepjs.

Object.defineProperty(navigator, 'deviceMemory', { value: 4 })

I am making exactly this and its returnig undefined.

Can you share your code?

from creepjs.

Yes i can.

Here :

js_code = f""" Object.defineProperty(navigator, 'deviceMemory', {{ "get": () => 4 }}); """ driver = uc.Chrome(options=options) driver.execute_cdp_cmd("Page.addScriptToEvaluateOnNewDocument", {"source": js_code})

from creepjs.

Here it is. If we run Object.getOwnPropertyDescriptor like so, it correctly returns undefined. If we apply the change and run it again, it fails. It should always return undefined with those arguments.

Pardon me, i did not realize that were a diferent method.
Thank you very much.
