I got a client with Windows 10 Pro that key loggers will never work on
I tried
Quasar's builtin key logger
Revenge's builtin key logger
Metasploit's key logger
Costex key logger
Aradamax key logger
and another one written by python
none of it works although all of them are tested and working fine in a virtual environment.
I also Disabled the Antivirus and the Windows Defender
so is there any service or software that might be blocking key loggers I should search for ?
side note: Remote Desktop as well never works for some reason it only shows black screen all the time.

Do you use any third party apps?

What do you mean exactly by third party apps ?

Which Software is installed else? For example its running something like this https://www.qfxsoftware.com/
But it depends on if and which input you get from the keylogger

gonna check the installed Software

another thing I forgot to mention

I had been trying for more than 5 days now all the SMTP based keyloggers sent nothing.
Quasar Rat worked once and gave me that

which I don't know what the hell is it.

I assumed he is typing in a language that's not English and that Quasar doesn't support other languages but at least the SMTP based keyloggers would have sent the same logs, right ?

Looks exactly like what the Software does i linked. But i wonder why it just come through once, may the software tampers somehow with some .dll

It looks like the keylogger couldn't convert the vcode, it can be due 2 things which are:
- The rat/keylogger doesn't support your language or it is not multi-language
- Something is encrypting it, example keyscrambler (mentioned above)

if i forgot something correct me.

yeah it's either such a software or he is just writing in a different language than those supported by the keyloggers I used.
don't know tho why it didn't show except once that's the weird part although he is a developer and I think he types a lot don't know really ..
Anyway Thanks for replaying tho.

nah you didn't forget anything it's one of those for sure but sending once only and not showing anymore is just weird
Thanks for replaying tho.
