URGENT Since today (06/28/2020) BAS is detected as a bot by google after UPDATE

[0xSentinel]

No these example ways how to detect browser versions from other element except Canvas, user-agent header etc.
TCP stack sounds overkill I dont think google use it, maybe mostly for banks and financial institutions.

Haven't tried recaptchav3 much since few months back where I scored 0.7 many times but most times were 0.1 and 0.3 using fingerprint switcher. I can look into it again when I have time later. For now I don't think problem because not many sites uses recaptcha v3 at the moment but as soon as it becomes a problem to me I will make sure to find a solution.

Have you tried set user agent to as close to stock Chromium as possible? I think this is what CEF is based on so using Googles own product as useragent and hope to bypass their own system is hard job. Better try set the user agent header for Chromium, Brave, etc and other browsers using Chromium.

@0xSentinel

Yes it is exactly true, my bot operates in the following way :

• first it will get a fingerprint and assigned it a score according to the results from multiple tests (Recapctha V3 is the first one).

• if the score is low, browser is resetting and go to get another fingeprint and test it again
• until to find a fingerprint that pass google whit a minimum score of 0.7 the bot continue to get and try fingerprints ...

I take for example my works from this last month, the bot has never exceeded 3 or 4 attempts before having a fingerprint which obtains a score of 0.7 at least, today i can let it run for hours it no longer finds any fingerprint which get socre more than 0.3, so i wase thinking of a problem with fingerprints from fingerprinswitcher, to test this hipothese i use a profile that have a fingerprint which has a score of 0.7 on Recapctah V3 befor the problem, and it does not pass the test, it now gets a 0.3, it seems that the problem does not come from fingerprintswitcher.

I can look into it again when I have time later. For now I don't think problem because not many sites uses recaptcha v3 at the moment but as soon as it becomes a problem to me i will make sure to find a solution.

It is not my case :) I am impacted by this problem and must find a solution to be able to continue to use BAS :)

Yes, as i said i strongly doubt that this is the case for google, it was just to evoke all the possibilities on this post in order to avoid future quesitons...

You are right It is quite obvious, i will try and give you my feedback.

thanks

@jonigood How are you even getting an score of 0.3? I am getting only a score of 0.1 which causes me to get a lot of captchas, How are you getting a score of 0.3? Also how are you putting in verification checks to get fingerprints that are above a specific score? Could you help me do that?

[jonigood]

@tatwa Hi, each user of BAS have these tips and configurations to get a better score, it depends on a lot of parameters, you must configure and test your project before launching the recaptcha test, you must pass all the online detection tests like f.vision ect ect ... this n 'is that you have to try recatcha, i provided one or two test project on this post, try them ...

[tatwa]

@jonigood I am passing all the online detection tests and that is not what I am asking about, What I am asking is how are you implementing a test to filter out fingerprints that give a low score and only select fingerprints that are high quality and use them?

@tatwa

• Set browser setting
• Get Fingerprint
• Apply fingerprint
• Proxy set (to synchronize language/geolocation/webrtc/timezone)
• Open link : recaptcha v3 socre request link
• parse result : capture text score like 0.1, 0.3, 0.7, 0.9 ...
• If :
  capture text score less then 0.7
  stop script and start it again (whit a loop or label ...)
• else :
  continue your script ....

@jonigood Что ты какой-то сказочник. Скор дает еще гретый профиль.
Кстате у меня с кучей авторизации в нормальном хроме тоже 0.3.

I scrolled through with my regular browser with regular activity. Recaptcha must have had an update as I was hit with lots of captchas. Before I got about 80-90% of the times green checkbox but the last day I have had to solve fast fading images.
This is with a stock browser and clean IP.
No wonder then it's harder to get good score.

Figured I tell you this, may be valueable to you.

@FastSpace Я раньше рукапчей увлекался, так там после 10-15 минут решения рекапчи в боте вообще score до 0.1 падал. Кроме прогретого профиля влияет и количество решённых за последнее время рекапч, и то, насколько давно вы последний раз грели профиль и, наверное, уйма других факторов.

friends, please write in english, we don't understand notthing, google translat is ineffective with abbreviated russian language ...

I never had less than 0.9 on a real chrome

@0xSentinel hi, Recaptcha V3 updated its code betwen the 27/06/2020 and 28/06/2020 ... it is now very "difficult" (to not write "impossible") to obtain an acceptable score of 0.7 whit BAS.
