  • The malware continuously monitors its access to GitHub (for exfiltration) and npm (for propagation). If an infected system loses access to both channels simultaneously, it triggers immediate data destruction on the compromised machine. On Windows, it attempts to delete all user files and overwrite disk sectors. On Unix systems, it uses shred to overwrite files before deletion, making recovery nearly impossible.

    shred is intended to overwrite the actual on-disk contents by overwriting data in the file prior to unlinking the files. However, shred isn’t as effective on journalled filesystems, because writing in this fashion doesn’t overwrite the contents on-disk like this. Normally, ext3, ext4, and btrfs are journalled. Most people are not running ext2 in 2025, save maybe on their /boot partition, if they have that as a separate partition.

    It could be a backronym, where the meaning of something is changed after the name is selected to fit the name. I mean, the company is Chinese. I doubt that they initially chose an English-based name, but they sure could have adopted it later.

    And yes, at least according to Wikipedia:

    https://en.wikipedia.org/wiki/BYD_Company

    “BYD” is the pinyin initials of the company’s Chinese name Biyadi. The company was originally known as Yadi Electronics (亚迪电子), named after the Yadi Road in Dapeng New District, where the company was once based.[23] According to Wang Chuanfu, when the company was registered, the character “Bi” (比) was added to the name to prevent duplication, and to provide the company with an alphabetical advantage in trade shows.[24] As the name “BYD” had no particular meaning, BYD started adopting a backronymic slogan “Build Your Dreams” when it participated at the 2008 North American International Auto Show in the US.[25][26][27]

    EDIT: Ah, @[email protected] already pointed this out.




  • From my /etc/resolv.conf on Debian trixie, which isn’t using openresolv:

    # Third party programs should typically not access this file directly, but only
    # through the symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a
    # different way, replace this symlink by a static file or a different symlink.
    

    I mean, if you want to just write a static resolv.conf, I don’t think that you normally need to have it flagged immutable. You just put the text file you want in place of the symlink.


  • Also, when you talk about fsck, what could be good options for this to check the drive?

    I’ve never used proxmox, so I can’t advise how to do so via the UI it provides. As a general Linux approach, though, if you’re copying from a source Linux filesystem, it should be possible to unmount it — or boot from a live boot Linux CD, if that filesystem is required to run the system — and then just run fsck /dev/sda1 or whatever the filesystem device is.



  • I’d suspect that too. Try just reading from the source drive or just writing to the destination drive and see which causes the problems. Could also be a corrupt filesystem; probably not a bad idea to try to fsck it.

    IME, on a failing disk, you can get I/O blocking as the system retries, but it usually won’t freeze the system unless your swap partition/file is on that drive. Then, as soon as the kernel goes to pull something from swap on the failing drive, everything blocks. If you have a way to view the kernel log (e.g. you’re looking at a Linux console or have serial access or something else that keeps working), you’ll probably see kernel log messages. Might try swapoff -a before doing the rsync to disable swap.

    At first I was under suspicion was temperature.

    I’ve never had it happen, but it is possible for heat to cause issues for hard drives; I’m assuming that OP is checking CPU temperature. If you’ve ever copied the contents of a full disk, the case will tend to get pretty toasty. I don’t know if the firmware will slow down operation to keep temperature sane — all the rotational drives I’ve used in the past have had temperature sensors, so I’d think that it would. Could try aiming a fan at the things. I doubt that that’s it, though.


  • My only complaint is that the volume knob does not work.

    I’d guess, without looking, that instead of controlling hardware in the interface, it probably intends to talk to the PC. It may do this by presenting itself as an attached USB keyboard and simulating media key presses.

    If this is Linux, you’re likely seeing XF86AudioLowerVolume and XF86AudioRaiseVolume keysyms sent. You can run xev (this works on Wayland as well, but be sure to have your mouse cursor over the xev window) and turn the knob to check.

    This would be consistent with it doing that:

    https://old.reddit.com/r/SoundBlasterOfficial/comments/ox2xhs/sound_blaster_x4_volume_issue/

    Firstly, the volume knob control directly adjust the PC master volume, it is a great feature as external volume button however the volume changes is so drastic that even a 2% up in master volume can be uncomfortably loud.

    If this is Linux, you can probably set up software to have those keysyms do whatever you want when pressed, but under Wayland, it’ll depend on the compositor you’re using. I use sway, which doesn’t appear to have them do anything out of box, but you could set it up to fiddle the volume on your currently active sound output or whatever.


  • Note that just because a sound interface is on USB is not a hard guarantee that you aren’t going to get noise from the power supply leaking into the audio, if it’s getting power from the USB port. USB power can be remarkably dirty. I owned one USB audio interface that also let very audible noise into the output, as well as other (more expensive) interfaces that don’t. Or at least that I could hear; I didn’t try running measuring hardware against it. Very much possible to have power supply circuitry inside the USB audio interface clean that up, but it costs more money, so…

    I wish that there was someone that intentionally induced noise on the USB power lines and tested USB audio interfaces to see how much leaks through into their output, but I haven’t seen anyone out there doing that.

    Worst case, it is possible to get a powered USB hub and just plug a single USB DAC into it, at least.


  • The motherboard has functioning built-in surround sound. And yet they sold my father a goddamn Soundblaster.

    The SoundBlaster card may have a better signal-to-noise ratio than whatever on-motherboard sound is present, even if the motherboard has sound hardware with a lot of outputs.

    …speaking as someone who has used sound hardware with annoying noise that could be induced when the CPU was under load.
