How they got the name What they are How they spread How to prevent them
and how to prevent their annoying evil twin, virus hoaxes
PC Viruses
How they got that name
How they got the name
PC Viruses
Computer viruses are called viruses because they share some of the traits of biological viruses.
• A computer virus passes from computer to computer like a biological virus passes from person to person.
How they got the name
PC Viruses
A biological virus is not living.
• It’s a fragment of DNA inside a protective jacket. Unlike a cell, a virus has no way to do anything or to reproduce by itself -it is not alive.
Computer viruses also can not reproduce by themselves
How they got the name
PC Viruses
A biological virus inject itself into a cell
• And uses the cell's existing machinery to reproduce itself
A computer virus “piggybacks” on top of a program or document
• And “reproduces (gets executed)
• Once running, it’s able to infect other programs or documents
PC Viruses
What they are
What they are
PC Viruses
A virus is a small piece of software (code) that piggybacks on real programs, like Excel, that have “embedded executable languages”
• Macro languages -- Visual Basic, etc.
• Each time the program runs the virus runs, too
• and it has the chance to reproduce (by attaching to other programs) or wreak havoc.
What they are
PC Viruses
E-mail viruses
• An e-mail virus moves around in attachments to e-mail messages, and usually replicates itself by automatically mailing itself to dozens of people in the victim's e-mail address book.
What they are
PC Viruses
Dave Parry, TPC User explains
• Most e-mails are sent as plain ASCII text, which cannot run programs.
• Word and Excel files can carry viruses because they have a macro language. • The files as such are quite harmless if they have no macros.
• One way to cleanse WinWord DOC files is to save them as RTF, which is text only and no macros.
What they are
PC Viruses
TPC October Meeting participants respond:
• email that uses HTML coding can carry viruses embedded in the HTML coding of the message. • Users have a choice to use HTML coding or not
• the suggestion from the floor was to turn it off
What they are
PC Viruses
Trojan Horse
• A Trojan horse is a computer program
• The program claims to do one thing
(it may claim to be a game)
but instead does damage when you run it
(it may erase your hard disk)
• Trojan horses have no way to replicate automatically.
What they are
PC Viruses
Worms
• A worm is a small piece of software that uses computer networks and security holes to replicate itself.
• A copy of the worm scans the network for another machine that has a specific security hole. • It copies itself to the new machine and starts replicating from there
What they are
PC Viruses
Worms and Trojan horses are actually more common today than viruses.
• Antivirus programs offer protection against all viruses, worms, and Trojans • refer to all of these types of malware as viruses.
PC Viruses
How they spread
How they spread
PC Viruses
A virus runs first when a legitimate program is executed.
• The virus loads itself into memory and looks to see if it can find any other programs on the disk.
• If it can find one, it modifies it to add the virus's code to the new program. • Then the virus launches the "real program."
How they spread
PC Viruses
The user has no way to know that the virus ever ran.
• Unfortunately, the virus has now reproduced itself, so two programs are infected. • The next time either of those programs gets executed, they infect other programs, and the cycle continues.
How they spread
PC Viruses
When the infected program
• is distributed by
• floppy disk • uploaded to a bulletin board • zipped and delivered as an executable
• then other programs get infected
This is how viruses spread
How they spread
PC Viruses
Virus Attacks
• Some sort of trigger will activate the attack phase, and the virus will then "do something” • Anything from printing a silly message on the screen to erasing all of your data.
• The trigger might be a specific date, or the number of times the virus has been replicated, or something similar.
How they spread
PC Viruses
Virus creator’s tricks
• load viruses into memory so they ran in the background • infect the boot sector on floppy disks and hard disks
PC Viruses
How to prevent them
How to prevent them
PC Viruses
Run a secure operating system like UNIX or Windows NT
• security features keep viruses away
Buy virus protection software Avoid programs from unknown sources (like the Internet) Stick with commercial software purchased on CDs
How to prevent them
PC Viruses
With E-mail viruses
• defense is personal discipline
• Never double-click on an attachment that contains an executable program • Attachments that come in as
• Word files (.DOC), spreadsheets (.XLS), images (.GIF and .JPG), etc., are data files • and they can do no damage • excepting the macro virus problem in Word and Excel documents mentioned above
How to prevent them
PC Viruses
With E-mail viruses
• defense is personal discipline
• Never double-click on an attachment that contains an executable program • A file with an extension like .EXE, .COM or .VBS is an executable
• and an executable can do all sorts of damage • once run, you have given it permission to do anything on your machine.
• Never run executables from e-mail.
How to prevent them
PC Viruses
Don’t victimize yourself
• learn where to find legitimate information on hoaxes, myths etc.
• do not forward warnings if you haven’t personally checked them out!

How to prevent them
PC Viruses
Some rules of thumb:
• if you merely find JDBGMGR.EXE on your computer, then it's probably not infected;
But. . .
• if you receive JDBGMGR.EXE as an email attachment, then it probably is infected.
How to prevent them
PC Viruses
TPC Member Jim Tittsler reports:
• “...there have been problems with buffer overflows where downloading a message with carefully crafted Date: header was enough to execute code.
• No attachment, no preview or "opening" required, since the attack begins when the client retrieves the Date: header of the message from the server.
• http://www.iss.net/security_center/static/4953.php

PC Viruses
"False Authority Syndrome”
• Most people who claim to speak with authority about computer viruses have little or no genuine expertise.
• The person feels competent to discuss viruses because of
• his job title, • because of expertise in another computer field, • simply because he knows how to use a computer
How to prevent them
PC Viruses
E-mail is clearly the predominant vulnerability point for viruses
• Current viruses are spread via security holes in Microsoft Outlook and Outlook Express
• Free patches are available from Microsoft to address these problems
• many people are reluctant to apply them.
How to prevent them
PC Viruses
First, update your system with Windows Update and Office Update
• or, buy a Mac

How to spot a hoax

"Thoughts travel faster in a vacuum."
• Think about it. By removing the actual thinking process, thoughts can travel uninhibited and thus exceed all logical bounds. • In addition, such thoughts often tend to become hyperdriven (adj. driven by hype).
How to spot a hoax
PC Viruses
Rule of thumb: If you receive a virus
alert message, don't believe it.
• There are warnings usually in ALL CAPS about reading or downloading an e-mail message
• Also look for the multiplication of exclamation marks.
• Salvation by immediate deletion is also nearly universal.
How to spot a hoax
PC Viruses
For some reason the word "miscreant" is a common catchphrase in hoaxes. Hoax viruses always seem to wield the powers of a vengeful binary god.
• Such godlike viruses can often do nasty things to your system that are beyond the abilities of software, mere mortals, or even most hardware technicians.
How to spot a hoax

(it says) forward this mail to anyone you care about.
• Here it is. This is the replication engine. This is what gives the virus the pesky lifelike ability to multiply. This is also a dead giveaway that it is a hoax.

The Authoritative Source Syndrome
• "Whoa! The FCC. This must be real."
• This aspect of cited authority is meant to lend credibility to the hoax.
• The truth is, however, that according to the FCC they have never, and will never, send out virus warnings.
How to spot a hoax

Superlative abilities of the virus:
• unparalleled in its destructive capability • this virus is "highly intelligent”
• Odd. All the viruses seen (at IBM Research) are extremely dumb.
• “most destructive” • “most polymorphic” • “stealthiest” virus.

The language is crafted to sound technical. It uses computer jargon
• It tends to lend credibility to the hoax.
• Do you believe that a CPU can be melted down by "an nth-complexity infinite binary loop”?
