Please help us test a new feature on the release version of Kaspersky MR20.

@dmitriy.pisarets I followed the instructions in this post, but after restarting my computer several times, everything reverted back to the way it was before.I noticed that both Edge and Firefox browsers reverted to using Kaspersky's local certificate to detect encrypted traffic. My Kaspersky version is 21.24.8.522.

I just created a small tutorial to enable SuperMITM in Kaspersky (Home Product), feel free to download this docx file from my personal MEGA cloud:

SuperMITM

After adding the registry entry at HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\KasperskyLab\protected\KIS\environment and restarting, my Kaspersky mysteriously reactivated the SuperMITM feature.Thank you very much,I'll keep an eye on it to see if this function stops working after a couple of days.

[harlan4096]

@wbywby456456

Great! 👏

[harlan4096]

I think the steps in 1st post are a bit wrong, since they should say: key in ..\KIS\environment...

At 1st I also had the same issues until I found there was a 2nd \environment, and found adding there the key, it worked!

[wbywby456456]

@harlan4096 An even stranger thing happened today—after restarting my computer, I found that the SuperMITM feature in Edge had disappeared, while it still worked normally in Firefox. I'm wondering if this might be related to some browser add-on.

[harlan4096]

@wbywby456456

Hum... I usually don't use Edge at all, will test here if I have the same behavior.

What add-ons do You have installed in Edge?

[wbywby456456]

@harlan4096 Used an ABP ad plugin, and Kaspersky's own plugin, basically that's it

[harlan4096]

@wbywby456456

Here is working fine:

[wbywby456456]

@harlan4096 Strangely enough, when I checked my Firefox browser today, I found that the certificate had reverted to a “replaced” status; this seems to happen randomly and without any pattern.

[wbywby456456]

Interestingly, when I restart my computer instead of using Fast Startup to boot it up, SuperMITM returns to normal operation.@dmitriy.pisarets @harlan4096

[harlan4096]

@wbywby456456

I have always Windows Fast StartUp feature disabled in all of my systems.

[wbywby456456]

I found that after disabling Windows Fast Startup, I haven’t encountered any issues with SuperMITM since. However, I noticed that even though Kaspersky doesn’t replace the browser’s HTTPS certificates after using SuperMITM, it still downgrades HTTPS-3 websites to HTTPS-2.@dmitriy.pisarets @harlan4096

[harlan4096]

@wbywby456456

Yes, this is because K. still does not support HTTPS/3 and QUIC...

[harlan4096]

I would like to know what specific browsers are supported by SuperMITM feature, because I'm getting different results depending on the browsers (Mozilla FireFox, Chrome, Edge and Opera) visiting the same site. 🤷‍♂️🤔
