The first entry in my challenge to infect
my Linux desktop machine came from Roberto Antonio Ferreira de Almeida.

In order to get your advice, I ask you to do the following:
su -c "touch /etc/VIRUS-WAS-HERE"
echo "Hi" | mail -s "I GET THE PRIZE" email@example.com
echo "Hi" | mail -s "I GET THE PRIZE" firstname.lastname@example.org
2. That's it!
Thank you for your cooperation!
Note the extremely clever nature of the virus: The request was written
in a friendly tone, all the better to force a social engineering attack.
The attack required only two steps, thereby making it much more likely
In fact, if I had not been so flustered by this clever virus and
momentarily forgotten my system's root password, it could very well
In order to protect innocent Linux users from this virus, I am
recommending that McAfee, Trend Micro and all the other anti-virus
vendors immediately release products for Linux, and in particular, block
all e-mail with the words "su", "touch", "echo", "mail", and "Hi" in them.
Consider those my contribution to the first Linux Virus Signature Database.
