Right, this is re-hash of the "Good Times" virus hoax. If
you consider what it's saying carefully you'll see that it's absurd.
Obviously, a text e-mail message body can't delete your hard drive.
It would have to (a) be a program and (b) be loaded, as a program,
into memory by the OS or called by a running program. It would be
real hard to get your virus code from an e-mail text item into the
CPU's instruction registers, especially if the hexadecimal values
for the code had to map into readable English text! I don't know if
you've ever tried typing a program before but there isn't usually
much readable text in there.
Seriously, a weakness in a particular e-mail program might be exploited
in a way similar to this, i.e., as in the the internet worm case,
but if such a weakness were uncovered and exploited, which would be
far more difficult for e-mail than for ftp (for the reasons noted
above), only one specific e-mail program would be affected, and probably
only specific versions.
I think we're safe from the "Penpal" virus.

a message i received from a friend at BELL ATLANTIC
-- If anyone receives mail entitled: PENPAL GREETINGS! please delete
it WITHOUT reading it. This is a warning for all internet users -
there is a dangerous virus propogating across the internet through
an e-mail message entitled "PENPAL GREETINGS!".
DO NOT DOWNLOAD ANY MESSAGE ENTITLED "PENPAL GREETINGS!"
This message appears to be a friendly letter asking you if you are
interested in a penpal, but by the time you read this letter, it is
too late. The "trojan horse" virus will have already infected
the boot sector of your hard drive, destroying all of the data present.
It is a self-replicating virus, and once the message is read, it will
AUTOMATICALLY forward itself to anyone who's e-mail address is present
in YOUR mailbox!
This virus will DESTROY your hard drive, and holds the potential to
DESTROY the hard drive of anyone whose mail is in your inbox, and
who's mail is in their inbox, and so on. If this virus remains unchecked,
it has the potential to do a great deal of DAMAGE to computer networks
worldwide!!!!
Please, delete the message entitled "PENPAL GREETINGS!"
as soon as you see it! And pass this message along to all of your
friends and relatives, and the other readers of the newsgroups and
mailing lists which you are on, so that they are not hurt by this
dangerous virus!!!!
Good Times Hoax Update

Yes. It is a joke both literally and technically.
Basically, his is re-hash of the "Good Times" virus hoax.
If you step back and think about what's involved
you can see why this is absurd. A text e-mail message body cannot
delete your hard drive. For a virus to get from a static message body
(data being manipulated by an application) to running it would first
have to be a binary executable (not text) and it would have to be
be loaded as a program into memory by the OS or called by a running
program, e.g., as a DLL.
To do this, the CPU's instruction pointer would have
to skip from the application code to the starting memory address of
the virus program which is the application's data. i.e., a file attachment.
Given an attached virus program file, it would have to be loaded into
memory, and the application or OS would have to change the CPUs instruction
pointer to start executing data rather than the e-mail program's own
code. In addition to the virtual impossibility of accomplishing these
things through mere message text, a properly written program would
never be capable of executing its data lieu of its own code. In the
Internet worm case, it was a serious bug of this kind that made the
whole thing possible.
A weakness in a specific e-mail program might be
exploited in a way similar to this, i.e., as in the famous Internet
worm case, but it would be difficult because the mechanisms necessary
to do it would be specific to one e-mail package and to one platform/OS.
In the Internet worm case, the OS was UNIX.
Some interesting possibilities arise through cross-platform
macro and scripting languages such as Word Basic and Lotus Script.
The Word Macro Virus is an example of this.
The biggest risk in Internet-connected shops is from
users downloading files over the Internet with web browsers and ftp
utilities. More program files come in this way than through e-mail.
Nonetheless, if you're concerned about viruses via e-mail, buy MIMESweeper
from Central House Technologies.

Hi CC:Mail administrators,
Just received the attached mail talking about "PENPAL GREETINGS"
virus.
Is it a hoax similar to the
"GOOD TIMES" virus we had seen on the NET or is it for real
?
Any info/confirmation will
be most welcome.
