    "Linux Virus is Hard …" - tilde.zone
    😂

    Copie ici:
    « Downloaded a virus for Linux lately and unpacked it.
    Tried to run it as root, didn't work.
    Googled for 2 hours, found out that instead of /usr/local/bin the virus unpacked to /usr/bin for which the user malware doesn't have any write permissions, therefore the virus couldn't
    create a process file.
    Found patched . configure and .make files on some Chinese forum, recompiled Tem Cee
    The virus said it needs the library
    cmalw-lib-2.0. Turns out
    cmalw-lib-2.0 is shipped with CentOS but not with Ubuntu. Googled for hours again and found an instruction to build
    a .deb package from source.
    The virus finally started, wrote some logs, made a core dump and crashed.
    After 1 hour of going through the logs | discovered the virus assumed it was running on ext4 and called into its disk encryption API. Under btrfs this API is deprecated. The kernel noticed and made this partition read-only.
    Opened the sources, grep'ed the Bitcoin wallet and sent $5 out of pity.
