A virus writer with something to prove has written a proof-of-concept
OpenOffice document to demonstrate a way to infect Windows, Linux and
Mac OS X systems with a single script.

The virus, dubbed BadBunny by antivirus firm Sophos, is a script
embedded in an OpenOffice Draw file and performs different actions
based on the host’s operating system. On Windows, the program drops a
file for the instant messaging client mIRC that attempts to spread the
virus. On the Mac OS X, the program places two Ruby scripts that
attempt to propagate the file, and on Linux systems, BadBunny drops
scripts written in Python and Perl to copy itself to other systems.
