  • It already is pretty rampant, however most Linux admins have minimal if any detection strategy.

    Additionally, while there’s plenty of binaries about like VoidLink, almost all campaigns against Linux hosts target SSH, or RCE vulnerabilities, and deliver shell scripts that orchestrate the attack.

    Why compile a binary when the shell has everything you need? The threat models are pretty different between Windows and the *nix world.

    When you look at botnet composition, they’re usually made up of outdated Linux hosts with SSH open with password-based authentication.

    Seriously people, switch to key-based auth and disable password auth entirely.










  • I’d rather a Mac than a Windows box. At least you get a proper shell (zsh or bash - zsh is the default now I think), python installed by default, can install package managers (macports, brew), can get coreutils, etc and most FOSS software from the Linux world runs since macs are UNIX at heart.

    I’m pretty sure cd isn’t even coreutils but implemented by shells as a wrapper for chdir/fchdir which is part of the kernel. Which has always bugged me since you can’t reliably pipe or redirect to cd since shells do things differently; it doesn’t handle stdin or the last component of a command runs in a subshell so doesn’t affect your current shell, blah blah.
