Text version:
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
and rerun it.
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
I 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.
And just linux in general. It's literally so weird
