I have Huawei HG8145V5 and I backed up config file which contains encrypted root and admin credentials, but I dont know how they are encrypted. Here is an example of one password

$2*FuHXY<y5$VJl(9f^9z%7;vR%K;84JG$.&O`qM17$

Can anyone identify which algo is used ?

It's probably AES. I saw config files at HG8245Hv5 and HG8245H5 and passwords are looking similar. A bit (just a bit:D) more info is here: https://the-infosec.com/2017/03/20/huawei-hg8245h-router-privilege-escalatio/

  • Hi, @Vido I have one question for you:) In this topic reverseengineering.stackexchange.com/questions/11626/… the issue of decrypting modem config file was discussed. It was recommended to find a file named 'tagparam_m', perform MD5sum of it, get this way AES-key, decrypt config file with this key, decompress zlib and finally get config file in xml. I want to ask you: where did you find this 'tagparam_m' file? I'm looking at firmware file directories (including /var), but I can't find this file. Thank you:)
