Title: Research: Viruses and Spam on the Internet


Mystic Mage - January 8, 2007 06:21 PM (GMT)
First lets start with

Spam

Definition: Spam is another term for unsolicited commercial email (UCE). Most people with an account on the Internet are familiar with spam - it usually is advertising "spamware" (software for spammers), pornography, shady MLM (multi-level marketing) deals, and other scams. Spam was originally used to describe unwanted, off-topic, excessive posting on usenet, but has come to include email as well.

Spammer

Definition: A spammer, simply, is a person who sends spam. Usually, these are people who think that they are going to get rich on the Internet by flooding it with messages and hoping for a response. They often do get a response. However, the response is from outraged people who receive the spam and complain to the ISP of the spammer, which usually gets the spammers dial-in accounts, email addresses, and/or web pages cancelled. Instead of deleting your spam, become one of those who fight spam.

How do they get email adresses?
By people themselves
From a mailing list
Buying lists from other spammers or companies
Specialized spambots
Using spambots that scour usenet
Using spambots to scour web pages

Spambot

Defintion:A Spambot is a piece of software, a program that someone has written. Which language it was written in does not matter, but most are probably written in C for speed and portability reasons. A spambot should not be confused with regular robots, also known as spiders or web-crawlers.

A spambot starts out on a web page. It scans the page for two things: hyperlinks and email addresses. It stores the email addresses to use as targets for spam, and follows each hyperlink to a new page, starting the process all over. Spambots also usually do not follow the guidelines in the robots.txt file, like civilized robots are supposed to. Most spambots are a part of a larger program, allowing them to send out the spam to email addresses as it find them. Others merely store the email addresses for later use.

Spambots vary in their intelligence and sophistication, but even the smartest can be fairly easily fooled by the tricks on this site. The simplest spambot would simply find mailto links, and follow each hyperlink as it comes up, until it reaches a dead end. The smartest ones can recognize email addresses in many forms, recognize dead links, avoid certain types of email addresses (such as *.edu and *.gov) and track many pages at once.

Note: Do not confuse the real spamming and annoying spamming. Spamming in games or chat is when someone says something over and over again. The real spamming is when they try to sell something

That was easy to find since you can find sites with good info(Got info from http://www.turnstep.com/Spambot/info.html) :p (The note was mine)

I won't go into to much detail but I'll post the 4 Viruses you'll find

Viruses - A virus is a small piece of software that piggybacks on real programs. For example, a virus might attach itself to a program such as a spreadsheet program. Each time the spreadsheet program runs, the virus runs, too, and it has the chance to reproduce (by attaching to other programs) or wreak havoc.

E-mail viruses - An e-mail virus moves around in e-mail messages, and usually replicates itself by automatically mailing itself to dozens of people in the victim's e-mail address book.

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 using the security hole, and then starts replicating from there, as well.

Trojan horses - A Trojan horse is simply 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.

I really see no need to go onto porn or anything

That's the info got out I'm gonna start on the research and look into WoW, CS and Guild Wars... While I'm at it anyone want me to check another game or anything?

A virus can replicate itself multiple times on run of a program and thusly infect more files... Viruses can also have a payload effect in which they are dormant until triggered either by a set date, a remote trigger, a set of keystrokes, or even rebooting the computer, once the trigger is activated the virus can then fulfill its preprogrammed mission, whether that be deletion of all files, specific files (such as doc files), or even just duplicating itself and filling every spare bit/byte of space on the computer. Sometimes a viral effect may be a simple message across the screen or system wide changes, it all depends on what has been programmed into it.

So no wonder, those stupid people were giving me stupid spams and they never stop. This happens all the time.

also don't get trojan and virus confused, a trojan is not self replicating and can be far more damaging than a virus. When a trojan infects your computer it then tries to connect out to a remote host, and when it does this, it turns every function of control of your computer over to the remote host. They can use any hardware attached to your computer (like open your cd/dvd drive, turn your microphone on and listen to whats going on by the computer), see any files you have, they can transmit them to themselves, they can basically lock you out of your own computer and steal every bit of info it posesses, and then if this wasn't bad enough, they can use this info for illegal means, ex phishing scams... or since they have you computer, they can use it to launch attacks on other computers, use it to spread viruses/trojans to all your friends


Snowflame - January 8, 2007 09:55 PM (GMT)
Speaking of trojans, I never heard of them.

VirusZero - January 8, 2007 11:23 PM (GMT)
Trojans are less heard of because they are easier to stop/prevent, they can't self replicate so once you nuke it then you won't have to worry about it popping up because it infected a normally harmless file, and often times once a trojan is detected then it is much easier to stop, because a simple firewall or router can negate it's effects ( by blocking the outbound path, it never connects to it's host so technically it can't send any data, and the host of the trojan doesn't know if the trojan sucessfully infected the target because they can't get a response from it. )
but trojans are also heard of less because the media often mislabels them as viruses, which is incorrect as they are an entirely different class of hazards, a connected trojan is infinitely more dangerous than a virus, a virus at max can wipe your harddrive, a trojan can expose your life to the internet and allow the host to do anything they want with anything they got from your computer (ex. scams, spam, fraud, attacks, even have you arrested.)

In my opinion, torajans are a lot harder to catch because they disguise themselves as legitimate processes, or programs on your computer..

I once had a trojan passing itself off as a .dll in my windows system 32 folder.

The name looked wierd, and so I googled the name and found that it was a trojan.

Basically, a trojan will disguise itself as a legitimate program, file, or process, and then will proceed to infest your computer at a later time.. (hence the name Trojan horse.

Well I really don't see any point looking into Viruses but I'm gonna have a look at some Game hacks
I hear alot of them on WoW and CS... nost sure bout Guild Wars

VirusZero - January 9, 2007 08:39 PM (GMT)
All I know about game hacks is that most games have an anti-cheating system set up, there are various methods that can be used, but the one I've heard of is this:

Using a server that you have to bypass before it'll let you into the game. Usually it works by the server pinging the game and asking for a list of plugins and the game sending the list (so that it shows that it hasn't been tampered with) so it'll allow you access. There are methods to bypass this but even if you do manage to use one then it's not a guarantee it'll work and you can use the hacks...
Plus even if you do slip through with hacks, if someone notices and reports you then they can easily check up on it... and then you'd be banned for cheating.

I read something about hacking once. It seemed fairly easy after you have the host computers IP. I won't explain anything but it is a nasty thing. I researched it after I had two trojans on my comp, which my anti virus caught. Sometimes those viruses are on files as simple as sprites or when you enter a site from google. That's also why I have anti-virus on my email. I run on a network so I don't want trojans getting through and having access to six computers.

CS is easy to hack... I've seen a lot of hack videos... here's one called "CS Pro Cheater" they think it's funny but it's stupid

WoW hacking is harder to get so i have to get some of people using it on private servers and one of someone recording a hacker

I'm looking for other hacks but it's hard to find some that are obliously not photoshopped

Snowflame - January 10, 2007 09:05 PM (GMT)
Could someone ask me what's a "Spyware"?

Mystic Mage - January 11, 2007 06:59 AM (GMT)
Ok...
What's a Spyware?

Snowflame - January 11, 2007 11:42 AM (GMT)
You don't know also Mystic?
