    Re: Dvr password

    It's a linux system so there is a filesystem there, and maybe the password is located in the filesystem and not in a separate NVRAM or SPI Flash, and maybe the password is even saved in cleartext.

    That's a lot of maybes, though.

    I filtered out all the textstrings out of the dump-file that are at least 8 readable characters long, and filtered that to strings that only contain the following characters:
    A-Z a-z 0-9 ! . -
    Then I sorted that and removed any duplicates.

    The result is 292 lines, and that's reasonable to look through:
    Code:
    $ strings -n 8 'FNK VISION XWH AVI5004-3520D V4.01B DVR PSW.BIN' | grep -E '^[A-Za-z0-9!.-]+$' | sort | uniq
    One line that sticks out as a typically human-sourced term is this: topsofia

    It appears to be the name of some instagram account:
    https://www.google.com/search?q=topsofia
    Perhaps it's a username on the device, but if not, maybe it's a password?

    However, if by "bios" you mean a bootstrap-environment on the device, then you wouldn't find a password to that on the operating system's filesystem, because the operating system is not loaded yet when the bootstrap executes.

        Consider this your one and only warning about ever asking for money around here.

          HP Omen 15-dh0052nf power-on & bios password
          by Nopslide
          Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

          My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).

          Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....

          Should I buy a Lenovo Thinkpad E495 with bios password?
          by RMDUiFT
          Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.

          I have a few questions:
