I haven't paid any attention to the virus scene for quite a while but the Bliss thing got me wondering. Found this at datafellows site, if anyone is interested. Doesn't look to me like being a Linux virus writer has any long term career opportunities.

NAME: Staog SIZE: 4744
This virus spreads only under Linux operating system, infecting Elf-style executables. Found in the fall of 1996, Staog is the first known Linux virus.
Staog is written in assembler. It attempts to stay resident and infect binaries as they are executed by any user. Stoag tries to subvert root access via three known vulnerabilities (mount buffer overflow, tip buffer overflow and one suidperl bug).
Staog contains several text strings, including:
Staog by Quantum / VLAD /dev/kmemx/etc/mtab~ /sbin/mount /tmp/t.dip /bin/sh /sbin/dip /tmp/t.dip chatkey /tmp/hs #!/bin/sh\nchmod 666 /dev/kmem\n/tmp/hs #!/usr/bin/suidperl -U\n$ENV{PATH}=\"/bin:/usr/bin\"; \n$>=0;$<=0;\nexec(\"chmod 666 /dev/kmem\");\n
VLAD is an Australian virus group, which also wrote the first Windows 95 virus, Boza.
Staog can be detected by searching all binaries for the following hex search string:
215B31C966B9FF0131C0884309884314B00FCD80
Staog is not known to be in the wild at the time of this writing (February 1997).
