Transcript of Malware
What is it, what does it do, and how do we stop it?
Dave Daku, CSC-124 at PCT (pct.edu)
the quick definition
Malware: Malicious Software
(and any other harmful software)
"viruses" not "virii"
a computer program which can infect a computer without the permission or knowledge of the owner
Often hidden in programs or documents, a virus
is activated when opened/executed
Viruses often seek to disable or destroy computers or data, but can act like almost any sort of Malware
a self-replicating progam which sends copies of itself
to any other computers on the same network
A worm's goal is just to propagate itself and infect as many networked systems as possible
Often worms are carriers for other types of malware which do the actual damage, or have that nefarious code built-in
a program which appears to be
legitimate, but is really malware
This sort of Malware completely bypasses all computer
security by tricking someone into allowing it to run
To avoid allowing Trojans in:
Never click on pop-up ads
Only open email attachments if you were expecting them
Be suspicious of any software you don't recognize
Be suspicious of any virus/malware warnings
designed to collect information about users without their knowledge
Usually delivered as a virus, worm, or trojan
Collects personal information and sends it home to The Bad People
one or more programs designed to obscure the fact that the system has been compromised
Usually accompanies another piece of malware, and hides itself and the other program
Sometimes intentionally spread by companies incorrectly attempting to enforce Digital Rights Management software
Prevents the user or any anti-virus software from cleaning the computer
SO MANY TERMS
Malware goes by many names, and comes in many subtle variations
Creators of malicious software rely on people not being able to keep up with each new type of attack
A comprehensive security program will protect against all types of Malware it knows about - keep your security software up-to-date!
Three types of security software can help keep you safe:
Prevents or eliminates spyware
Helps protect against viruses, worms, and trojans
Almost all Anti-Virus applications now also protect against SpyWare, making a dedicated program for that far less useful
Blocks unrecognized network communications
A firewall is your first line of defense, and comes packaged into Windows (and some other OSes): make sure it's on!
Is any harmful software
and comes in many forms
Involves having up-to-date protection software
and being careful with any suspicious files/messages
